Why Doesn't Fiddler Show Curl Traffic?

Question

Why doesn't Fiddler show curl traffic? Other traffic gets displayed, just not curl. How can I get fiddler to intercept curl traffic?

Fiddler will not intercept curl traffic by default. You'll need to specify the -x proxy option. If curl displays an SSL error message, additionally use the -k option to disable SSL validation.

curl -x 127.0.0.1:8888 -k www.example.com

Is there a way to get curl to trust the Fiddler root cert? – user24601 Nov 05 '17 at 21:25

In Telerik Fiddler Classic, use

curl --url example.com -x 127.0.0.1.8888 --ssl-no-revoke
