Capturing CURL Traffic with Fiddler Everywhere

Environment

Product	Fiddler Everywhere
Product Version	1.0.0 and above
3rd-party tool	curl
Supported OS	macOS, Linux, Windows

Description

Some 3rd-party tools like curl doesn't use the OS system proxy by default. To intercept traffic generated from similar applications, we will need to explicitly set the Fiddler Everywhere proxy.

CURL

When executing a request through curl (that needs to be captured by Fiddler), use the optional parameter -x to pass the Fiddler Everywhere proxy. The ssl-no-revoke option tells curl to disable certificate revocation checks. The -v parameter is to show verbose logs after the command is executed.

curl --url https://www.example.com/ -x 127.0.0.1:8866 --ssl-no-revoke -v

Alternatively, you could set the proxy settings for your terminal app (which runs the curl app) to use the Fiddler Everywhere proxy.
