Curl command to test the API - api

Question

I need to test an API of following spec
URL: http://myapp.com/api/upload/
Method: POST
Parameters:
image: (binary data of image)
returns
a JSON Object
sample php implementation to test the api
<?php
$ch = curl_init();
$url = 'http://myapp.com/api/upload/';
$fields = array('image'=>file_get_contents('profile-pic.jpg'));
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_URL, $url);
$json = curl_exec($ch);
echo "\n".$json."\n";
?>
I use RESTClient and Poster extensions to test other api, I'm not sure how to send binary data for a parameter named image with those tools.
How do I test the above api using Curl command?
No luck with this one
curl -X POST --data-binary "image=#test.jpg" "http://myapp.com/api/upload/"
test.jpg is in current directory. I can't change the 3rd party API, to be able to test with other encoding formats.

Answer 1

curl -X POST --data-urlencode 'image#test.jpg' 'http://myapp.com/api/upload'
It’s image#, not image=#.
This is assuming that the image data is urlencoded before sending, which is what I figure the PHP code does.

Answer 2

CURLOPT_POSTFIELDS with a hash array in PHP corresponds to the command line -F option. Thus, it should be something similar to:
curl -F image=#profile-pic.jpg http://myapp.com/api/upload/
If that isn't the exact thing, add '--trace-ascii dump.txt' to get a full trace logged and check that out closely to see what's wrong.
