HTTPS multipart/form-data POST

See more HTTP Examples

Demonstrates how to send a multipart/form-data POST over HTTPS (using TLS). Perl

use chilkat();

$success = 0;

# 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 = chilkat::CkHttpRequest->new();

$req->put_HttpVerb("POST");
$req->put_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->put_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() . "\r\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 = chilkat::CkHttp->new();

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

$resp = chilkat::CkHttpResponse->new();
$success = $http->HttpSReq("www.myserver.com",443,1,$req,$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print "HTTP response status: " . $resp->get_StatusCode() . "\r\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:" . "\r\n";
print $htmlStr . "\r\n";
