desire2learn: create user API path - desire2learn

Question

I am trying to use the path
POST /d2l/api/lp/(D2LVERSION: version)/users/
and am running into an error. I'm hoping there is something not in the documentation that I am missing, because from what I can tell, this should work.
HTTP/1.1 400 Bad request
Cache-Control: private
Content-Length: 0
Server: Microsoft-IIS/7.5
X-XSS-Protection: 0
X-Powered-By: ASP.NET
Date: Wed, 23 Jan 2013 18:37:07 GMT
The data I'm sending looks like this:
{
"OrgDefinedId":"190006002",
"FirstName":"Jesty",
"MiddleName":"Q",
"LastName":"McTest",
"ExternalEmail":"privateemail#gmail.com",
"UserName":"190006002",
"RoleId":115,
"IsActive":true,
"SendCreationEmail":true
}
My PHP code looks like this at the moment:
$random_hash = "xxBOUNDARYxx";
$request ="--".$random_hash.
"\r\nContent-Type: application/json\r\n\r\n$data\r\n\r\n--".
$random_hash;
$length=strlen($request);
$url = $opContext->createAuthenticatedUri($url,"POST");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("HTTP/1.1", "Content-Type: multipart/form-data; boundary=xxBOUNDARYxx","Content-Length:".$length));
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_POST,true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
return curl_exec($ch);

Ok, after several hours of tinkering I figured it out. The original code I posted was based off of code that worked for posting the profile image through the API. The code for just posting JSON was much simpler. Here is a generic PHP function for sending JSON to Valence through the POST method
/*
* $opContext is your user context object
* $url is the route
* $data is the well formed JSON in a string ( use json_encode() )
* $ct is the count of json fields
*/
static function basic_post($opContext,$url,$data,$ct){
$url = $opContext->createAuthenticatedUri($url,"POST");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_POST,$ct);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
return curl_exec($ch);
}
