I won’t talk about fiddler’s background here, but baidu has many tutorials as well. Here I will focus on some of the problems that occurred during the trial.
Here are a few steps to try out the Fiddler capture tool:
1. Configure the proxy
The configuration of the proxy needs to be specific to the configuration of the browser to capture the package configuration of that browser proxy. The first step to configure the proxy is to know the address of the local machine, which can be viewed by CMD after Win+R and enter ipconfig after calling the command line
The ipv4 option is the local IP address. The default fiddler port is 8888. It can be set to any other port, but it is important not to conflict with other software ports.
2. Install the certificate
The purpose of installing the certificate is to enable Fiddler to grab packets from HTTPS, which is the protocol that small games use to communicate with the server. So to catch small games, small procedures of the students will need to install the certificate this step. I won’t explain the steps here, but there are many tutorials online.
Now that you’re ready to grab HTTPS packages, the next section is a practical example of grabbing a small game package and changing its value.
