php curl - access url via browser response: 200 access url via curl response:401?

I have a url which contains all information in the url (username/password/content ect)

If i visit the u开发者_开发百科rl in my browser I get a successful response.

However If I visit the url through curl I get 401.

There is no authentication on the url.

What could be causing this?

Code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://mconnect.co.nz/v1/sendmessage?appname=app&pass=pass&msgclass=test&msgid=6&body=Some+Content&to=02712345678');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, $mconnect[$index]['app_name'] . ":" . $mconnect[$index]['app_pass']);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.12 (KHTML, like Gecko) Chrome/9.0.587.0 Safari/534.12');
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_POST, false);
if(curl_exec($ch) === false) 
  echo 'fail: '.curl_error($ch);

So,

I am building my url through $mconnect[$index]['url'] . '?' . http_build_query($url);

which gives me the above url.

So,

If I have

$url = $mconnect[$index]['url'] . '?' . http_build_query($url);
curl_setopt($ch, CURLOPT_URL, $url);

I get the 401.

But,

If I then do echo $mconnect[$index]['url'] . '?' . http_build_query($url);

I get

http://mconnect.co.nz/v1/sendmessage?appname=app&pass=pass&msgclass=test&msgid=6&body=Some+Content&to=02712345678

so if I then do

$url = 'http://mconnect.co.nz/v1/sendmessage?appname=app&pass=pass&msgclass=test&msgid=6&body=Some+Content&to=02712345678';
    curl_setopt($ch, CURLOPT_URL, $url);

Then it works...

any ideas?

The server is likely verifying the user-agent. You probably need to set it to whatever your browser uses.

The parameters you're sending might need to be sent via POST.

$posts = array('pass' => 'password', 'body' => 'lots of content'); // ... etc;
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $posts);

And if this is the case you might not need to use the CURLOPT_USERPWD option.

"There is no authentication on the url." however i see

curl_setopt($ch, CURLOPT_USERPWD, $mconnect[$index]['app_name'] . ":" . $mconnect[$index]['app_pass']);

isnt that for authentication?

Note: You may also try sending the HTTP login details like this

curl_setopt($ch, CURLOPT_URL, 'http://'.$mconnect[$index]['app_name'] . ":" . $mconnect[$index].'@mconnect.co.nz/v........

Try setting the authorization header manually. With something like

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Basic ' . base64_encode($mconnect[$index]['app_name'] . ":" . $mconnect[$index]['app_pass'])));

Although not sure why The fix was to build the URL myself instead of using php 5's build_query_string
