HTTP GET with Non-USASCII Query Params

See more HTTP Examples

This example illustrates how query parameters in a URL are typically encoded and transmitted. Perl

use chilkat();

$success = 0;

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

# First, let's load the string "Grünhöfer GmbH" from a file.  (This is a fictitious company name.)
# The file uses the utf-8 charset encoding.
$sbCompanyName = chilkat::CkStringBuilder->new();
$success = $sbCompanyName->LoadFile("qa_data/txt/companyName.txt","utf-8");
# Assuming success for this example...

# We'll send an HTTP GET request to https://chilkatsoft.com/example?company_name={company name}

# When sending an HTTP GET request with query parameters that contain accented characters 
# (e.g., umlauts: ä, ö, ü), they must be percent-encoded (URL encoded) to ensure proper transmission and 
# interpretation by the server.  This is based on their UTF-8 byte values.
$sbUrl = chilkat::CkStringBuilder->new();
$sbUrl->Append("https://chilkatsoft.com/example?company_name=");
$sbUrl->Append($sbCompanyName->getEncoded("url","utf-8"));

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

# Send the following HTTP GET request:

# GET /example?company_name=Gr%C3%BCnh%C3%B6fer%20GmbH HTTP/1.1
# Host: chilkatsoft.com
# Accept: */*
# Accept-Encoding: gzip

$sbResponse = chilkat::CkStringBuilder->new();
$success = $http->QuickGetSb($sbUrl->getAsString(),$sbResponse);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print "response status code: " . $http->get_LastStatus() . "\r\n";
print $sbResponse->getAsString() . "\r\n";
