Demonstrates how to call the HttpJson method, which sends an HTTP POST with a JSON body. This example sends the following request:

POST /echo_request_body.asp HTTP/1.1
Host: chilkatsoft.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

Perl

use chilkat();

$success = 0;

$http = chilkat::CkHttp->new();
$success = 0;

$json = chilkat::CkJsonObject->new();

# Build the following JSON:  {"greeting":"Hello World"}
$json->UpdateString("greeting","Hello World");

# This URL echoes the contents of the request body, letting us view it.
$url = "https://chilkatsoft.com/echo_request_body.asp";

# Send a POST with the JSON in the HTTP request body.
$resp = chilkat::CkHttpResponse->new();
$success = $http->HttpJson("POST",$url,$json,"application/json",$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print "Response Status Code: " . $resp->get_StatusCode() . "\r\n";

# Examine the request we sent.
# The LastHeader property stores the HTTP request header of the most recent request sent,
# and in this instance, the response body mirrors the request body.
print $http->lastHeader() . "\r\n";
print $resp->bodyStr() . "\r\n";

# Output:

# POST /echo_request_body.asp HTTP/1.1
# Host: chilkatsoft.com
# Accept: */*
# Accept-Encoding: gzip
# Content-Type: application/json
# Content-Length: 26
# 
# {"greeting":"Hello World"}
