How to call the api interface in python

There are actually two ways to call the windows API. The first is through the third-party module pywin32.

If you have pip installed, you can install pywin32 through pip

Run pip list on the command line to check whether pywin32 is installed

As shown in the figure

Here we call the most basic API of Windows, MessageBox, which can display a dialog box.

The editor will not introduce too much here, but simply describe the MessageBox interface. MessageBox is an API interface of windows, and its function is to display a dialog box.

The prototype is:

int WINAPI MessageBox(HWND hWnd,LPCTSTR lpText,LPCTSTR lpCaption,UINT uType);

The first parameter hWnd indicates that the dialog box belongs to Which window, lpText is the window prompt information, lpCaption is the window title, and uType defines the buttons and icons of the dialog box.

Here we need to import the win32api module (belonging to pywin32). If macro definition is needed, the API macro is defined in the win32con (also belongs to pywin32) module.

Here we only import a win32api module, and then simply call MessageBox to display a dialog box.

If we don’t know how to install the pywin32 module, or we don’t want to install this third-party module. At this time we have another way.

Call the Python built-in module ctypes. If you have a foundation in Windows programming, or have read a little bit of MSDN, you should know that the Windows API actually exists in the form of a dll file (dynamic link library).
