How to use Fiddler to grab Apple bags

1. Mobile phones and computers need to be connected to the same network: the same local area network or the same WiFi signal.

2. Configure Fiddler

First download and install Fiddler. After running, select the menu Tools- > Fiddler Options to open the https page.

Select "Decrpt HTTPS traffic" and Fiddler can intercept HTTPS requests

Check Ignore server certificate errors (unsafe)

Open the Connections page and select "Allow remote computers to connect" to allow other machines to send HTTP/HTTPS requests to Fiddler.

Click OK.

Restart Fiddler.

3. Install the certificate

Get the IP address of the current computer, for example, here is: 10.102.2.215

Then open safari in iPhone and access the address http://10.102.2.215:8888, click "FiddlerRoot certificate" and install the certificate.

Install the certificate.

4. Set Fiddler as the proxy

Open Settings-> WiFi on iPhone, click the I icon after the current WIFI to view the current connection information, scroll to the HTTP agent at the bottom, and switch to "Manual"

Fill in your IP address and corresponding port number: 8888.

5. After the configuration is completed, you can open your phone APP, and the network request will be uploaded to Fiddler through the same local area network or WiFi for packet analysis.

6. Because some users have adopted IPv6's IP address network. Currently, the HTTP agent through IPv6 cannot open the certificate download page for Fiddler

It is recommended that you first switch to the IPv4 network for Fiddler setting, and then switch the network to IPv6 for HTTP proxy setting and packet capture analysis.
