(PHP Extension) Creating an application/json HTTP POST Request

Demonstrates how to create an HTTP POST request having the Content-Type application/json, where the body of the HTTP request is the following JSON:

{
   "username" : "my_username",
   "password" : "my_password",
   "validation-factors" : {
      "validationFactors" : [
         {
            "name" : "remote_address",
            "value" : "127.0.0.1"
         }
      ]
   }
}

The generated HTTP request looks like this:

POST /something HTTP/1.1
Content-Type: application/json
Accept: application/json
Host: domain
Content-Length: 216

{
  "username": "my_username",
  "password": "my_password",
  "validation-factors": {
    "validationFactors": [
      {
        "name": "remote_address",
        "value": "127.0.0.1"
      }
    ]
  }
}

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example demonstrates building an application/json request.

$req = new CkHttpRequest();

// The ContentType, HttpVerb, and Path properties should
// always be explicitly set.
$req->put_HttpVerb('POST');
$req->put_Path('/something');
$req->put_ContentType('application/json');

// We may wish to add an "Accept" header to the request.
// This tells the server we'll accept an application/json response.
$req->AddHeader('Accept','application/json');

// We'll use Chilkat's JSON API to create the JSON body of the HTTP request.
$json = new CkJsonObject();
$json->AppendString('username','my_username');
$json->AppendString('password','my_password');
// vFactors is a CkJsonObject
$vFactors = $json->AppendObject('validation-factors');
// vArray is a CkJsonArray
$vArray = $vFactors->AppendArray('validationFactors');
$vArray->AddObjectAt(0);
// factorObj is a CkJsonObject
$factorObj = $vArray->ObjectAt(0);
$factorObj->AppendString('name','remote_address');
$factorObj->AppendString('value','127.0.0.1');

// Use the JSON for the HTTP request body
// By default, the Emit method will output compact JSON.
// This is best for generating the smallest size request.
// To generate a more human-readable (pretty-printed) JSON request body,
// set the EmitCompact property to FALSE
$json->put_EmitCompact(false);
$req->LoadBodyFromString($json->emit(),'utf-8');

// View the request that would be sent if SynchronousRequest was called:
$requestMime = $req->generateRequestText();
print $requestMime . "\n";

// A few important comments about the HTTP request that is generated:
// 
// 1) The Content-Length header is automatically generated based on the actual length of the MIME message
//    that follows the intial (topmost) MIME header.
// 2) The HOST header will automatically get filled in with the actual domain when SynchronousRequest
//    is called
