The whole process of linux C++ crash stack capture
1. Crash signal processing When a program crashes, the operating system sends a signal to the program to notify it that an exception has occurred. In C++, you can register a signal handler through the signal function so that the program can execute custom code when it receives the signal. #include <execinfo.h> #include <signal.h> #include […]
Android—screen adaptation processing skills
A few years ago, screen adaptation has been a major problem that troubled Android development engineers. However, with the birth of various screen adaptation solutions in recent years and the launch of various Google adaptation controls, screen adaptation has become increasingly easier.

iOS in-app packet capture, NSURLProtocol intercepts network requests within APP
Foreword When developing, you need to obtain data in the SDK. Since you cannot see the code, you can only monitor all network request data and intercept the corresponding return data. This can be achieved through NSURLProtocol, and can also be used to interact with H5. 1. NSURLProtocol intercepts requests 1. Introduction to NSURLProtoco Official […]
