Referring to fig. 1, fig. 1 is a schematic structural diagram of a data access system to which a data access method according to an embodiment of the present disclosure is applied, and as shown in fig. 1, the data access system may include a data access device 10 and a server 20 communicatively connected to the data access device 10. The data access device 10 may include, but is not limited to, a smart phone, a tablet computer, a desktop computer, or the like. The server 20 may be a smartphone, tablet or desktop computer, etc.
The data access device 10 further includes application programs 30 (only one of which is shown in the figure).
In the embodiment of the present application, the data access device 10 is further configured with a predetermined connection pool (not shown in the figure). The preset connection pool is used for storing a plurality of connections, and the connections are used for sending a data access request from the application program 30 to the server 20 and returning response information for the data access request from the server 20 to the application program 30. The data access request is used to request data, i.e., response information corresponding to the data access request, to be acquired from the server 20.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a data access method according to an embodiment of the present application. In the embodiment of the application, the execution subject of the data access method is a data access device. As shown in fig. 2, a data access method provided in an embodiment of the present application may include S201 to S203, which are detailed as follows:
in S201, calling a target connection from a preset connection pool through an application program, and sending a first data access request to a server; and the server is used for returning response information according to the first data access request.
In the embodiment of the application, when an application program in the data access device needs to access the server, the data access device may call the target connection from the preset connection pool through the application program, and send the first data access request to the server. Wherein the target connection refers to a connection for sending the first data access request.
It should be noted that, when the data access apparatus invokes the target connection from the preset connection pool through the application program and sends the first data access request to the server, the server may return response information according to the first data access request, that is, the response information is for the first data access request.
In S202, an operating system snoop function is called to perform a snoop operation on the response information.
In the embodiment of the application, after the data access device sends the first data access request to the server, an operating system monitor function can be called to monitor the response information. The os snoop function may be determined according to actual needs, and is not limited herein, and the os snoop function may be, for example, an epoll function, a select function, or a poll function.
In an embodiment of the present application, since the epoll function is used to listen for the response message, the data access device does not need to add an additional module to poll for the response message, and the target connection is configured with a Socket (Socket), and the application is configured with a callback function.
The socket is a basic operation unit of network communication supporting a Transmission Control Protocol (TCP)/Internet Protocol (IP), and may be regarded as an end point of two-way communication performed by processes between different hosts, which is simply an agreement between two communicating parties, and a communication process is completed by using a related function in the socket.
A callback function refers to a function called by a function pointer. In particular, a pointer (address) to a function may be passed as a parameter to another function, and when this pointer is used to call the function to which it points, the function to which it points is a callback function. It should be noted that the callback function is not directly called by the implementing side of the function, but is called by another side when a specific event or condition occurs, and is used for responding to the event or condition.
Based on this, the data access device can specifically implement the listening operation through steps S301 to S302 shown in fig. 3, which are detailed as follows:
in S301, the target connection is placed in a listening queue of the epoll function, and the target connection is bound to the callback function.
In this embodiment, the epoll function may monitor multiple connections at the same time, and therefore, the data access device may place the target connection in a monitoring queue of the epoll function. Meanwhile, in order to return the response information to the application program in time when the epoll function monitors the response information, the data access device can also bind the target connection with the callback function, so that the data access device can call the target connection to acquire the response information through the callback function when monitoring the response information.
In S302, the epoll function is called to monitor the socket of the target connection.
In this embodiment, after the data access device places the target connection in the listening queue of the epoll function and binds the target connection with the callback function, the data access device may call the epoll function to listen to the socket of the target connection, and determine whether response information for the first data access request is returned.
In the embodiment of the application, after calling the monitoring function of the operating system to perform monitoring operation on the response information, the data access device determines whether the response information is returned or not through the monitoring function of the operating system. If the data access device monitors the response message, the data access device executes step S203.
It should be noted that, in an actual application, since the server will send the response information of the data access request to the application program in a short time after receiving the data access request, in another embodiment of the present application, after the data access device calls the operating system snoop function to perform a snoop operation on the response information, if the response information of the data access request is not returned within the first preset time period, which indicates that the response information of the data access request is lost, the data access device sends the second prompt information to the application program. The first preset time period may be set according to actual needs, and is not limited herein, and for example, the first preset time period may be one minute. The second prompt message is used for prompting that the response message of the data access request is not monitored in the first preset time period.
In S203, if the response information is monitored, the application program calls the target connection to acquire and load the response information.
In the embodiment of the application, after monitoring the response information, the data access device indicates that the server returns corresponding information according to the first data access request, and therefore, the data access device can call the target connection through the application program to acquire and load the response information.
In an embodiment of the application, after the data access device calls the target connection through the application program to obtain and load the response information, the target connection can be put back to the preset connection pool, so that the data access device can conveniently continue to use the target connection to send other data access requests to the server.
As can be seen from the above, in the method provided in this embodiment, the target connection is called from the preset connection pool through the application program, and the first data access request is sent to the server; the server is used for returning response information according to the first data access request; calling an operating system monitoring function to monitor the response information; and if the response information is monitored, calling the target connection through the application program to acquire and load the response information. According to the data access method, the first data access request is sent by obtaining the target connection in the preset connection pool, and the response information is obtained by calling the target connection when the response information is monitored, so that the first data access request in the data access method does not need to carry identification information, the response information corresponding to the first data access request does not need to be determined through the identification information, the response information corresponding to the first data access request can be obtained by only calling the target connection sending the first data access request, the data access method is simple in implementation process, the complexity of a processing process is reduced, and the processing efficiency is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating an implementation of a data access method according to another embodiment of the present application. With respect to the embodiment corresponding to fig. 2, the data access apparatus of the present embodiment further includes S401 after S202, which is detailed as follows:
in S401, if the response message is not monitored, a first preset operation is performed.
In this embodiment, when the data access apparatus does not listen to the response information, the first preset operation may be executed. The first preset operation may be set according to actual needs, and is not limited herein.
In an implementation manner of the embodiment of the present application, the first preset operation may be: and calling a second connection from the preset connection pool through the application program, and sending a second data access request to the server. Wherein the second connection is different from the target connection and the second data access request is different from the first data access request.
The data access device executes the first preset operation, so that the data access device can continue to call a new connection from the preset connection pool through the application program and send the new data access request to the server without waiting for the response information of the first data access request to return after sending the first data access request to the server, and the speed of processing the data access request by the data access device is improved.
In another implementation manner of the embodiment of the present application, the first preset operation may further be: and processing the preset transaction. The preset transaction may be determined according to actual needs, and is not limited herein. It should be noted that the preset transaction refers to a transaction other than sending a data access request to the server.
As can be seen from the above, according to the data access method provided in this embodiment, when the response information is not monitored, the first preset operation may be executed, so that the data access apparatus does not need to wait for the response information to return when the response information is not monitored, but may execute other operations.
In practical applications, because the target connection is usually configured with an execution function, and the data access apparatus usually calls the target connection to execute the execution function through the application program to implement sending of the data access request and returning of the response information, after the data access apparatus calls the target connection to execute the execution function through the application program and sends the data access request to the server, the data access apparatus can only wait for the return of the response information all the time, and continue to call the target connection to execute the execution function to obtain the response information, and then can process other transactions, which not only takes a long time, but also reduces the processing efficiency of the data access apparatus.
Based on this, in one embodiment of the present application, the data access device splits the execution function of the target connection into a sending function and a receiving function, i.e., the target connection is configured with the sending function and the receiving function. Referring to fig. 5, fig. 5 is a flowchart illustrating an implementation of S201 and S203 in the embodiment corresponding to fig. 2 according to the present application; in some possible implementations of the present application, the S201 specifically includes S501, and the S203 specifically includes S503, which is detailed as follows:
in S501, the sending function is executed through the target connection, and the first data access request is sent to the server.
In S202, an operating system snoop function is called to perform a snoop operation on the response information.
In S503, the target connection is called by the callback function to execute the receiving function, and the response information is received.
In this embodiment, when the data access device needs to send the first data access request to the server, the target connection may be called from the preset connection pool through the application program, and the sending function is executed through the target connection, so as to send the first data access request to the server.
After the data access device sends the first data access request to the server, the data access device can also call an operating system monitoring function to monitor the response information. The os snoop function may be determined according to actual needs, and is not limited herein, and the os snoop function may be, for example, an epoll function, a select function, or a poll function.
In an embodiment of the present application, since the epoll function is used to listen for the response message, the data access device does not need to add an additional module to poll for the response message, and the target connection is configured with a Socket (Socket), and the application is configured with a callback function.
The socket is a basic operation unit of network communication supporting a Transmission Control Protocol (TCP)/Internet Protocol (IP), and may be regarded as an end point of two-way communication performed by processes between different hosts, which is simply an agreement between two communicating parties, and a communication process is completed by using a related function in the socket.
A callback function refers to a function called by a function pointer. In particular, a pointer (address) to a function may be passed as a parameter to another function, and when this pointer is used to call the function to which it points, the function to which it points is a callback function. It should be noted that the callback function is not directly called by the implementing side of the function, but is called by another side when a specific event or condition occurs, and is used for responding to the event or condition.
When the data access device monitors the response information, the target connection can be called through a callback function of the application program, and the response information is received by executing the receiving function through the target connection.
As can be seen from the above, in the data access method provided in this embodiment, the executing function of the target connection is split into the sending function and the receiving function, so that the data access device can respectively call the sending function or the receiving function of the target connection as needed, and when the response information is monitored, the receiving function of the target connection is called to receive the response information without waiting for the return of the response information, thereby improving the processing efficiency of the data access device.
Referring to fig. 6, fig. 6 is a flowchart illustrating an implementation of a data access method according to still another embodiment of the present application. With respect to the embodiment corresponding to fig. 2, the data access device in this embodiment further includes steps S601 to S603 after S201, which are detailed as follows:
in S601, response information returned by the server is received.
In this embodiment, after sending the first data access request to the server, the data access device may receive response information returned by the server. And the response information is used for describing whether the server successfully receives the first data access request.
After receiving the response information returned by the server, the data access device may perform a corresponding operation according to the response information. If the data access device detects that the response information is used to indicate that the server successfully receives the first data access request, which indicates that the data access device has successfully sent the first data access request, then step S602 is executed; if the data access device detects that the response information indicates that the server has not received the first data access, and indicates that the data access device has failed to send the first data access request to the server, the data access device executes step S603.
In an embodiment of the present application, the failure of the data access apparatus to send the first data access request to the server may be: the data access device does not receive the response information sent by the server within a second preset time period. The second preset time period may be set according to actual needs, and is not limited herein.
In S602, if the response information is used to indicate that the server successfully receives the first data access request, a second preset operation is performed.
In this embodiment, when the data access device detects that the response information is used to indicate that the server successfully receives the first data access request, it indicates that the data access device successfully sends the first data access request to the server, and therefore, the data access device may perform the second preset operation. The second preset operation may be set according to actual needs, and is not limited herein.
In an implementation manner of the embodiment of the present application, the first preset operation may be: and calling a second connection from the preset connection pool through the application program, and sending a second data access request to the server. Wherein the second connection is different from the target connection and the second data access request is different from the first data access request.
The data access device executes the first preset operation, so that the data access device can continue to call a new connection from the preset connection pool through the application program and send the new data access request to the server without waiting for the response information of the first data access request to return after sending the first data access request to the server, and the speed of processing the data access request by the data access device is improved.
In another implementation manner of the embodiment of the present application, the first preset operation may further be: and processing the preset transaction. The preset transaction may be determined according to actual needs, and is not limited herein. It should be noted that the preset transaction refers to a transaction other than sending a data access request to the server.
In S603, if the response information is used to indicate that the server does not receive the first data access request, sending first prompt information to the application program; the first prompt message is used for prompting that the first data access request fails to be sent.
In this embodiment, when the data access device detects that the response information is used to indicate that the server has not received the first data access request, it indicates that the data access device has failed to send the first data access request to the server, and therefore, the data access device may send the first prompt information to the application program. The first prompt message is used for prompting that the first data access request fails to be sent.
As can be seen from the above, in the data access method provided in this embodiment, after the first data access request is sent to the server, the response information sent by the server may also be received, and it is determined whether the first data access request is successfully sent to the server according to the response information, so that the data access device may execute corresponding operations according to whether the first data access request is successfully sent to the server, and the processing efficiency of the data access device is improved.
In another embodiment of the present application, the data access apparatus may further perform an initialization operation on a preset number of connections before the first data access request is sent to the server by using the application program to call the target connection from the preset connection pool, and place the connections after the initialization operation in the preset connection pool. When the data access device needs to send a data access request to the server, the target connection can be directly obtained from the preset connection pool without creating a new connection, so that the time and the resources of the data access device are saved, and the processing efficiency of the data access device is improved.
The preset data may be set according to actual needs, and is not limited here, for example, the preset number is determined according to how many data access requests need to be sent. The initialization operation refers to restoring the connection to a default state.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
