Perl

Send HTTP POST using non-UTF8 such as Windows-1250

See more HTTP Examples

Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST. Perl

use chilkat();

$success = 0;

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$http = chilkat::CkHttp->new();

$req = chilkat::CkHttpRequest->new();

# Load a JSON file containing strings with Polish chars.
$json = chilkat::CkJsonObject->new();
$success = $json->LoadFile("qa_data/json/has_polish_chars.json");
if ($success == 0) {
    print $json->lastErrorText() . "\r\n";
    exit;
}

# Add the request params expected by the server-side:
$req->AddParam("tytul",$json->stringOf("tytul"));
$req->AddParam("tresc",$json->stringOf("tresc"));

# Indicate we wish to explicitly send the charset attribute in the HTTP request header.
$req->put_SendCharset(1);

# Send the POST
# You can send the POST to the URL below.  It will respond with the request body in quoted-printable format.
# Using quoted-printable, we can easily see the binary bytes for the accented chars.

$req->put_HttpVerb("POST");
$req->put_ContentType("application/x-www-form-urlencoded");

$resp = chilkat::CkHttpResponse->new();
$success = $http->HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",$req,$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print $http->lastHeader() . "\r\n";
print $resp->bodyStr() . "\r\n";

# Sample output:

# --------------------------------------------------
# POST /echoPost.cshtml HTTP/1.1
# Host: www.chilkatsoft.com
# Content-Type: application/x-www-form-urlencoded; charset=utf-8
# Content-Length: 79
# 
# <pre>tytul=3DPrzyk%C5%82ad&amp;tresc=3DPrzyk%C5%82ad
# %82oszenie</pre>
# --------------------------------------------------

# We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

# -----------------------
# However.. we can change the charset used for the HTTP request by specifying the request object's charset.

$req->put_SendCharset(1);
$req->put_Charset("windows-1250");
$req->put_HttpVerb("POST");
$req->put_ContentType("application/x-www-form-urlencoded");

$success = $http->HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",$req,$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print $http->lastHeader() . "\r\n";
print $resp->bodyStr() . "\r\n";

# Sample output...
# You can see how the bytes used for the Polish chars are now 1-byte per char (i.e. using Windows-1250) 

# --------------------------------------------------
# POST /echoPost.cshtml HTTP/1.1
# Host: www.chilkatsoft.com
# Content-Type: application/x-www-form-urlencoded; charset=windows-1250
# Content-Length: 70
