3. After saving, you can catch the request from the mobile phone.
4. Use a browser on the mobile phone to access http://IP: port, use the computer port and the port set by fiddler to access the installation certificate, access the network, and observe whether fiddler can successfully capture the packet. At this time, under normal circumstances, the mobile phone network can be accessed, and the packet capture is successful.
5. After connecting to the computer, the mobile phone may not be connected to the Internet, the solution

2. Open the mobile browser and enter: http://10.168.xx.xx:8888 , the host address in the middle is the address of the local machine found earlier.
3. The following screen appears, click the position pointed by the arrow, and click install.

This part of android and ios is a little different.
Method 1:
1) Android can be connected to the computer, open the memory card of the phone from the computer, and directly copy the certificate to the SD card.
2) Click Settings -> Security -> Install from SD Card -> Find the certificate from the internal storage space, click Install (the certificate name can be named whatever you want)
Method two:
1) Android can be connected to the computer, open the memory card of the phone from the computer, and directly copy the certificate to the SD card.
2) Find the storage location of the file on the phone, click on the file name, and you will be prompted to install (the name of the certificate can be named arbitrarily)
Method 3:

8. View HTTPS
Open fiddler, Tools——>Fiddler Options…, switch to the HTTPS tab, check all the options, click Save, and you can view the HTTPS interface
#8. Setting up filtering
1. After setting up the proxy on the mobile phone, all the requests from the pc and app are caught on fiddler at this time. If the URL is opened on the pc, there will be a lot of requests. At this time, the filtering function needs to be turned on.
2. Open fiddler>Tools>Fiddler Options>HTTPS>…from remote clients only, check this option.
…From all processes: catch all requests
…From browsers only: only grab browser requests
…From non-browsers only: Only grab requests from non-browsers
…From remote clients only: only grab remote client requests
(note: if the phone is set to proxy, remember to restore it after testing and playing, otherwise the phone cannot access the Internet normally.)
