How to capture http messages from Request Node library with Fiddler

Question

Regular client initiated requests to the node server are captured fine in Fiddler. However, requests sent from node to a web service are not captured. It did not help to pass in

Answer 1

To do this on an ad-hoc basis, without changing your code, you can use environment variables.

Request respects:

• HTTP_PROXY
• HTTPS_PROXY
• NO_PROXY

So, to proxy just set these in your console before running your process.

For example, to setup http and https proxy use:

set HTTP_PROXY="http://127.0.0.1:8888"
set HTTPS_PROXY="http://127.0.0.1:8888"
set NODE_TLS_REJECT_UNAUTHORIZED=0

The latter line stops issues with SSL through the fiddler proxy.
