1. First, you need to download and install the Charles packet capture tool. You can find the version suitable for your operating system on the official website ( https://www.charlesproxy.com/) and follow the installation wizard to install it.

2. After the installation is complete, start Charles. If you are using it for the first time, you may see an "SSL Proxying" setting prompt box. Select Allow and install the Charles root certificate so that HTTPS requests can be crawled.

6. Now you can start performing various operations on the device, and Charles will automatically capture and display the relevant requests and responses. You can view the details of the request and even modify the request and response data.

7. If you want to filter and search for specific requests or responses, you can use the filtering function provided by Charles. Enter a keyword in the search box in the top toolbar, and Charles will display the corresponding content based on the matching results.

8. When you finish capturing packets, remember to turn off the proxy settings to avoid affecting other network access.
