Python

1. Install Proxyman on Python environment
By default, Python on macOS doesn't trust Proxyman self-signed certificate. As a result, you might encounter SSL Error if you try to intercept HTTPS traffic. 
If you would like to intercept HTTPS Traffic from your Python script, you have to explicitly tell Python to use the Proxyman Root Certificate at ~/.proxyman/proxyman-ca.pem
Please follow the guideline:
1.Install Proxyman Certificate on Mac (If you've done it, please skip it. If not, please check out MacOS Guideline).
2.Run the following CLI on your Terminal app
1
$ export SSL_CERT_FILE=~/.proxyman/proxyman-ca.pem
2
$ export REQUESTS_CA_BUNDLE=~/.proxyman/proxyman-ca.pem
3
$ echo "export REQUESTS_CA_BUNDLE=~/.proxyman/proxyman-ca.pem" >> ~/.bash_profile ; source ~/.bash_profile
Copied!
3. Done.
2. Revert the change
If you don't use Proxyman, please revert the change by commenting out:
1
# export REQUESTS_CA_BUNDLE=~/.proxyman/proxyman-ca.pem
Copied!
in ~/.bash_profile
3. Automatic solutions
1.Use the following script to automatically install/remove the certificate to Python.
2.Run python script.py add ~/.proxyman/proxyman-ca.pem

4. Troubleshooting
4.1 Proxyman could not capture HTTP traffic from my python code.
Solution: You have to explicitly tell python to use HTTP Proxy at IP=127.0.0.1 port = 9090.
You can find a solution by googling: macos python set http proxy
4.2 Get SSL Error when intercepting HTTPS Traffic
Solution: You have to tell Python to trust the Proxyman Certificate  at ~/.proxyman/proxyman-ca.pem
You can find a solution by googling: macos python trust self signed certificate
