Preface
In the process of learning crawlers, I gradually felt that there was something missing from simply relying on the browser's built-in packet capture. In order to understand network data more accurately, I hereby learn packet capture technology.
There are many kinds of capture tools, this time I will learn how to use fiddler
Tip: This is a summary of my practice
1. What is fiddler?
Fiddler is an http protocol debugging proxy tool. It can record and check all the http communication between your computer and the Internet, set breakpoints, and view all the "in and out" data of Fiddler (referring to cookies, html, js, css and other files) ). Fiddler is simpler than other network debuggers because it not only exposes http communication but also provides a user-friendly format.
It must have more functions than simply using the browser’s built-in packet capture tool
