Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST. Chilkat2 Perl

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

my $http = Chilkat2::Http->new;

my $req = Chilkat2::HttpRequest->new;

# Load a JSON file containing strings with Polish chars.
my $json = Chilkat2::JsonObject->new;
my $success = $json->LoadFile('qa_data/json/has_polish_chars.json');
if (!$success) {
    print $json->LastErrorText, "\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->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->HttpVerb('POST');
$req->ContentType('application/x-www-form-urlencoded');

my $resp = Chilkat2::HttpResponse->new;
$success = $http->HttpReq('https://www.chilkatsoft.com/echoPost.cshtml', $req, $resp);
if (!$success) {
    print $http->LastErrorText, "\n";
    exit;
}

print $http->LastHeader, "\n";
print $resp->BodyStr, "\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->SendCharset(1);
$req->Charset('windows-1250');

    exit;
}

print $http->LastHeader, "\n";
print $resp->BodyStr, "\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)
