At work, you often need to capture mobile app network packets. For example, if an image is inaccessible only on the mobile app but the web version is normal, you need to capture packets to quickly identify the cause of the problem. A common approach is to install packet capture software on your computer to act as a proxy, and then connect your phone to this proxy. This will allow the phone's network packets to pass through the packet capture software, allowing you to capture and analyze the packet details. Mastering the network packet details is like using Chrome's debugging tools; nothing can escape your gaze.
