Multipart upload

[alexyhkim]

I am trying to use node-curl to post an image to facebook's api, I have to use multipart/form-data as the content type because that is what their api expects. I thought node-curl would simplify this process, because facebook expects a simple curl request : curl
-F '[email protected]'
-F 'access_token=___'
"https://graph.facebook.com/act_368811234/adimages"

I tried duplicating the multipart example, but it failed, and trying to get this module to tell me anything useful about what happened has been a nightmare... no examples on how to "Retrieve data from curl". status, body, and header are all undefined, I'm assuming because the request failed. But the request's error handler callback is not firing at all. Trying to call .info() on the object built by CurlBuilder mysteriously logs some more information (no idea how this is happening as I am passing no parameters to .info(), which should then immediately throw an error, which it does eventually, but it logs some stuff) and I have no idea what to pass it (tried 'RESPONSE_CODE' which failed). Here is my code for reference:

var nc = require('node-curl'); var curlReq = nc.create(); curlReq.open(); curlReq('https://graph.facebook.com/act_1374394842779617/adimages', { VERBOSE: 1, MULTIPART: [ {name: 'balloons.jpg', file: req.files.file.path, type: 'image/jpeg'}, {name: 'access_token', contents: accessToken, type: 'text/plain'} ] }, function(e) { console.log("ERROR!!!!"); console.log(e); console.log(this.body); this.close(); });

    console.log(curlReq);

    console.log(curlReq.status);
    console.log(curlReq.body);
    console.log(curlReq.curl_);
    curlReq.close();

Here is my console's log:

Also, I don't know if you intended for other people to use this module, but the documentation and examples aren't very helpful. Needs to be way more detailed in exposing what's going on behind the scenes.

You close the curl before the request finished by code curlReq.close();. close should be in the callback function.
