Can a proxy (like fiddler) be used with Node.js's ClientRequest

Question

Can node.js be setup to recognize a proxy (like Fiddler for example) and route all ClientRequest's through the proxy?

I am using node on Windows and would like to debug the http requests much like I would using Fiddler for JavaScript in the browser.

Just be clear, I am not trying to create a proxy nor proxy requests received by a server. I want to route requests made by http.request() through a proxy. I would like to use Fiddler to inspect both the request and the response as I would if I was performing the request in a browser.

To route your client-requests via fiddler, alter your options-object like this (ex.: just before you create the http.request):

options.path = 'http://' + options.host + ':' + options.port + options.path;
options.headers.host = options.host;
options.host = '127.0.0.1';
options.port = 8888;

myReq = http.request(options, function (result) {
    ...
});

I find the following to be nifty. The request module reads proxy information from the windows environment variable.

Typing the following in the windows command prompt, will set it for the lifetime of the shell. You just have to run your node app from this shell.

set https_proxy=http://127.0.0.1:8888 
set http_proxy=http://127.0.0.1:8888
set NODE_TLS_REJECT_UNAUTHORIZED=0

If you want to montior outgoing reqeusts from node you can use the request module

and just set the proxy property in the options, like that

request.post('http://204.145.74.56:3003/test', {
headers :{ 'content-type' : 'application/octet-stream'}, 
'body' : buf ,
 proxy: 'http://127.0.0.1:8888'
}, function() {
   //callback
});

8888 is the default port , of fiddler .

Solution 4

process.env.https_proxy = "http://127.0.0.1:8888";
process.env.http_proxy = "http://127.0.0.1:8888";
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

Answering my own question: according to https://github.com/joyent/node/issues/1514 the answer is no, but you can use the request module, http://search.npmjs.org/#/request, which does support proxies.
