If you want to block HTTPS requests, you need to install a certificate, the code is as follows:
Attached is the code to determine if the certificate exists:
The results we achieved were as follows:
1. Interceptwww.itsvse.comSite request, which returns a piece of JSON content directly.
2. Block the down.itsvse.com site, and after the response, replace the string "Uploaded by" with "Uploaded by"
The code is as follows:
Then set the ie agent 127.0.0.1:9099 manually, also with the code settings, as follows:
The renderings are as follows:
Note: When modifying the content after the response, you need to set up a session in the BeforeRequest eventsession.bBufferResponse = true;, otherwise you can't modify the response content!
