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 clipboard can interact based on an interprocess communication technology, so that data transmission is realized.
The clipboard (clipboard) is essentially a group of functions and messages used for transmitting data in WINDOWS API, and provides an intermediary for data sharing between WINDOWS applications, and the established cut (copy) -paste mechanism of WINDOWS provides a shortcut for sharing data with different formats between different applications. When a user performs a cut or copy operation in an application, the application places the selected data on the clipboard in one or more formats. Any other application can then pick up data from the clipboard, selecting a format suitable for itself from the given formats.
The clipboard is a very loose exchange medium that can support any data format, each identified by an unsigned integer, whose value is a constant defined by the Win32 API for the standard (predefined) clipboard format; the non-standard Format can be registered as a new Clipboard Format using the Register Clipboard Format function. The data exchanged using the clipboard need only be consistent in data format or can all be converted to a certain format. However, the clipboard can only be used in Windows-based programs, and cannot be used on a network.
The ClipBoard (ClipBoard) is an area in the memory, is a very useful tool built in Windows, and a color bridge is erected through the small ClipBoard, so that information can be transferred and shared among various applications. However, the disadvantage is that the clipboard only holds one copy of data, and each time new data is entered, the old is overwritten.
Communication flow:
and (3) sending data:
(1) opening clipboard
(2) Emptying and occupying clipboard
(3) Putting data into the clipboard:
firstly, obtaining a heap memory Globlalloc
② locking the GlobaloLock of the heap memory and obtaining the first address of the heap memory
Third, put data SetClipboardData into clipboard
Releasing heap memory Globalenlock
(4) Closing clipboard
Receiving data:
(1) opening clipboard
(2) Checking data format in clipboard
(3) Obtaining data from the clipboard:

③ using GlobaalUnlock to unlock the memory
(4) Closing clipboard
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 inter-process communication with a second process corresponding to a clipboard through a first process corresponding to a browser or a WeChat applet, so that target resource content is obtained, and the obtained target resource content is fed back to an online banking system server (application system server) to perform service handling.
