No Root to achieve mobile phone packet capture, take wechat articles as an example

Caught the purpose

Two days ago, wechat introduced a paid article model, but the number of views of such articles is not publicly displayed. But for these hidden things, people want to know more.

First, let’s talk about the idea of obtaining relevant information without capturing packets. However, in the BS architecture, messages are transmitted through response headers and request headers, as well as the message body itself. That wechat article is actually a web page, copy the article link can be opened to non-wechat browser (such as Chrome).

Therefore, method one is to copy the wechat article and open it in a non-wechat browser, and view the request and response data through the developer tools of the current browser. The first problem with this operation is that although the corresponding interface and corresponding field are found, there is no data. There are two possible reasons, one is that I did not pay for this article, and the other is that in other browser environments, the values of these fields are not displayed.

However, after paying for the article, clicking on the link still shows paying to view all the content, which may be because the wechat browser environment cannot identify whether the user has purchased the article.

However, in wechat, there is no developer tool as powerful as desktop browser, so we can only use other tools to capture the data of relevant requests at the moment the article is opened.

Try something else

A search turned up two simple bag-catching apps that work directly on your phone, without the fiddle or Charles requirement that your phone work with your computer’s network environment. Packet Capture and AndroidHttpCapture respectively. The first try is the first one, when looking at the interface related data, there is a garbled code problem, looking for a good solution to use the second one.

Find the interface and click on it again to find that those fields have data. ReadCount and payCount are the number of readers and paycounts, respectively.

The link to the second tool is here, github.com/JZ-Darkal/A… .
