environment:
Native Mac (I use a Mac, the simulator installed in the first phase)
Simulator: mumu simulator - Portal
Let me tell you here, window supports most emulators, you can download them directly from Baidu, and there should be quite a few that support Mac, but I only found this one.
burp
Set address and port on burp
open emulator
Enter https://burp and click CA to download.
Find the file manager - click on the shared folder
Modify the downloaded CA file and change the suffix to .cer
Set name (whatever)
This will grab the package.
