// This example assumes the Chilkat HTTP API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example demonstrates how to send a multipart/form-data POST that
// looks like this:

// 	POST /cgi/XXX.pl HTTP/1.0
// 	Accept: text/html
// 	Connection: Keep-Alive
// 	User-Agent: XXX/8.0.15
// 	Content-type: multipart/form-data, boundary=XXXxyxy
// 	Content-Length: 682
// 
// 	--XXXxyxy
// 	content-disposition: form-data; name="UploadAgent"
// 
// 	InterfaceVersion1.5
// 	--XXXxyxy
// 	content-disposition: form-data; name="user"
// 
// 	userValue
// 	--XXXxyxy
// 	content-disposition: form-data; name="password"
// 
// 	passwordValue
// 	--XXXxyxy
// 	content-disposition: form-data; name="file"
// 
// 	fileValue
// 	--XXXxyxy
// 	content-disposition: form-data; name="data_version"
// 
// 	dataVersion
// 	--XXXxyxy
// 	content-disposition: form-data; name="content2"; filename="XXX"
// 
// 	THE FILE CONTENT GOES HERE...
// 	--XXXxyxy--
// 

// First, let's build the HTTP request object
$req = new COM("Chilkat.HttpRequest");

$req->HttpVerb = 'POST';
$req->Path = '/cgi/XXX.pl';

// The boundary string is automatically generated and added by Chilkat.
// The value for the boundary string doesn't matter. (As long as it's a unique string that doesn't occur elsewhere in the request.)
$req->ContentType = 'multipart/form-data';

// Adding the Connection: Keep-Alive is optional.  It only makes sense if the intent is to send
// additional requests to the same domain (your-namespace-sb.accesscontrol.windows.net) within a reasonable time period.
$req->AddHeader('Connection','Keep-Alive');

// --------------------------------------------------
// IMPORTANT: Never set the Content-Length header.  
// Chilkat will automatically compute the correct Content-Length and will add it.
// --------------------------------------------------

// If a specific User-Agent header field is needed, it can be added by calling AddHeader.
$req->AddHeader('User-Agent','XXX/8.0.15');

// The "Accept" header, if present, tells the server what Content-Type responses will be accepted.
// In this case, we're telling the server that we'll only accept "text/html" responses, and therefore
// the server SHOULD only send a text/html response.  Technically, the Accept header is not required.
$req->AddHeader('Accept','text/html');

// Add the params to the request.  Given that the Content-Type is set to "multipart/form-data", when
// Chilkat composes the request, it will put each param in it's own MIME sub-part (i.e. in it's own
// part delimited by the boundary string).
$req->AddParam('UploadAgent','InterfaceVersion1.5');
$req->AddParam('user','userValue');
$req->AddParam('password','passwordValue');
$req->AddParam('file','fileValue');
$req->AddParam('data_version','dataVersion');

// The last param is the contents of a file.
// If it's a file on disk, we can add it like this:
$pathToFileOnDisk = 'c:/someDir/someFile.dat';
$success = $req->AddFileForUpload('content2',$pathToFileOnDisk);
if ($success == 0) {
    print $req->LastErrorText . "\n";
    exit;
}

// Alternatively, if the contents of the file are in memory, perhaps in a string
// variable, the file can be added like this instead.
$fileContents = 'This is the content of the file being uploaded.';
$success = $req->AddStringForUpload('content2','XXX',$fileContents,'utf-8');

// -----------------------------------------------------------
// IMPORTANT: To duplicate the HTTP request shown above, you'll want to choose 
// either AddStringForUpload or AddFileForUpload, but not both.  It's possible to upload
// any number of files by calling AddStringForUpload and/or AddFileForUpload any number
// of times, once per file to be uploaded.  This of course assumes that the receiving
// end is programmed to receive multiple files..
// ------------------------------------------------------------

$http = new COM("Chilkat.Http");

// The request is ready... now send it using HTTPS (which is port 443 by default).

$resp = new COM("Chilkat.HttpResponse");
$success = $http->HttpSReq('www.myserver.com',443,1,$req,$resp);
if ($success == 0) {
    print $http->LastErrorText . "\n";
    exit;
}

print 'HTTP response status: ' . $resp->StatusCode . "\n";

// In this case, the response would be HTML because our Accept header
// told the server to only return HTML.  The HTML is available on the BodyStr
// property of the response object:
$htmlStr = $resp->BodyStr;
print 'Received:' . "\n";
print $htmlStr . "\n";
