Example one
An embodiment of the present application provides a data transmission method based on a pipeline, and as shown in fig. 1, the method may include the following steps:
step S101, a first process corresponding to a local target application program sends a service processing request to an application system server;
step S102, the application system server determines that the inter-process communication mode is a pipeline communication mode and resource request content based on the service processing request, and feeds back the determined inter-process communication mode and resource request content to the local target application program;
step S103, the first process corresponding to the local target application program transmits the resource request content to the second process corresponding to the pipeline program in a pipeline communication mode;

and step S106, the first process corresponding to the local target application program receives the service processing result sent by the application system server.
Inter-process Communication (IPC) refers to data sharing and data exchange between different processes.
Specifically, a first process corresponding to the local target application program and a second process corresponding to the pipeline can interact based on an interprocess communication technology, so that data transmission is realized.
Wherein Pipe (Pipe) is a communication channel with two endpoints: a process with one handle may communicate with a process with another handle. A pipe may be unidirectional-one end is read-only and the other end is write-only; or bi-directional-both ends of the pipe are both readable and writable.
(1) An Anonymous Pipe (Anonymous Pipe) is an Anonymous, one-way Pipe that transfers data between a parent process and a child process, or between two child processes of the same parent process. The pipe is typically created by a parent process, then inherited by a child process to be communicated by a read or write endpoint handle of the channel, and then communication is effected. The parent process may also establish two or more child processes that inherit the anonymous pipe read and write handles. These child processes can communicate directly using the pipeline, without going through the parent process.
An anonymous pipe is an efficient way to implement sub-process standard I/O redirection on a single machine, and it cannot be used on the web, nor between two unrelated processes.
Anonymous pipeline communication process:
r > parent process read-write process
Creating anonymous pipe
Creating sub-process and initializing the sub-process related data (assigning the input/output handle of the sub-process with the read/write handle of the anonymous pipeline).
And thirdly, closing the relevant handle of the child process. (Process handle, Main thread handle)
Read-write to pipeline
Sub-process read-write process
Obtaining I/O handle
② reading and writing for pipeline
(2) Named Pipe (Named Pipe) is a one-way or two-way Pipe for communication between a server process and one or more client processes. Named pipes can be used between unrelated processes and between different computers, where a server assigns a name to a named pipe when it is established, and any process can open the other end of the pipe by that name to communicate with the server process under the given authority.
Named pipes provide a relatively simple programming interface that makes transferring data over a network less difficult than communicating between two processes on the same computer, but do not care if it is to communicate with multiple processes simultaneously.
Named pipes have two communication modes:
A. byte mode: in byte mode, data flows between the client and server in a continuous byte stream
B. Message mode: in the message mode, the client and server transmit and receive data through a series of discontinuous data units, and after each message is sent on the pipeline, the message must be read in as a complete message
Communication flow:
a server side: creating named pipe- > server waits for user connection- > reads and writes data
A client: connecting named pipes- > opening named pipes- > reading and writing data
In particular, the local target application may be a browser or a wechat applet; the application system server can be an online banking system server; the business process request may be one or more of a certificate login, a form signature, and a certificate binding.
According to a specific application scenario of the application, a user can perform interprocess communication with a second process corresponding to a pipeline through a first process corresponding to a browser or a WeChat applet, so that resource content information needing to be acquired is sent to the second process corresponding to the pipeline, and then the second process corresponding to the pipeline program sends the acquired target resource content to an online banking system server (application system server) for service handling.
The embodiment of the application provides a data transmission method based on a pipeline, and the application sends a service processing request to an application system server through a first process corresponding to a local target application program; the application system server determines that the interprocess communication mode is a pipeline communication mode and resource request content based on the service processing request, and feeds back the determined interprocess communication mode and the resource request content to the local target application program; the first process corresponding to the local target application program transmits the resource request content to the second process corresponding to the pipeline program in a pipeline communication mode; a second process corresponding to the pipeline program sends the acquired target resource content to the application system server; the application system server is used for determining a service processing result based on the acquired target resource content; and receiving the service processing result sent by the application system server by the first process corresponding to the local target application program. The interaction between a local target application program (namely a browser or a wechat applet) and a pipeline program is realized through a pipeline communication mode of interprocess communication, so that target resource content is obtained, the problem that the development amount is large due to the fact that different plug-ins need to be developed for different browsers to achieve the fact that the browser or the wechat applet locally obtains the resource content is solved, the problem that the program is complex due to the fact that the browser generally needs to be restarted to achieve the function of the plug-in is solved, and the user experience can be improved.
