Apr 01, 2025 pm 08:24 PMFailed to catch the WeChat public account news list? Solutions to failure of Charles and Fiddler packet capture
Many developers often encounter the problem of failing to catch packets when trying to obtain the news list data of WeChat public account. This article provides analysis and possible solutions for the failure of using Charles and Fiddler to capture WeChat public accounts.
The problem is not a simple tool setting error, but WeChat's anti-crawling mechanism is at work. The questioner can only crawl the news details page data, which means that WeChat may use technologies such as encryption, data obfuscation or dynamic loading. Fiddler's limited support for the H2 protocol may also be one of the reasons for the failure of packet capture. Even more powerful Charles may not be able to bypass WeChat's more advanced anti-crawling measures.
Solution: WeChat's anti-crawl strategy is updated quickly and complex, and relying solely on Charles or Fiddler may not work. It is recommended to try the following more advanced strategies:
- In-depth analysis of network requests: Carefully study the network requests when the WeChat public account loads the news list, and analyze their request parameters, encryption methods and data structures.
- Simulate login: Try to simulate WeChat login to get more complete access.
- Advanced packet capture tools or techniques: Consider using more powerful packet capture tools or techniques, such as analyzing JavaScript code to find the source of data.
- Looking for alternatives: Direct crawling may not work, look for other ways to get the required data, such as the official API provided by WeChat (if it exists).
Important tips: When crawling WeChat official account data, you must comply with the rules and laws and regulations of the WeChat platform to avoid burdening the server or violating relevant regulations.
