Problem:

Sometime, if you open the fiddler for sniffing, then you send a GET request:

You will meet these great amount of errors, caused by _ssl.c:852 when the fiddler is sniffing.

---

Solution: 

 Configure HTTPS options, make system Browsers trust the Fiddler Certificate.

Swtich to Internet Options: 

 

Export the certificate, follow these steps. 

 

Store the ".cer" file then fill in this file with this ".cer" file path.

 Restart python, then as long as the response server does not have a certificate check, you can sniff the traffic yourself~!

 Attention:

When you finish sniffing and wanna shutdown fiddler for normal use, remember to set the verify parameter to None as default!!!
