Creating an application/json HTTP POST Request

See more HTTP Examples

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"
      }
    ]
  }
}

; This example demonstrates building an application/json request.

$oReq = ObjCreate("Chilkat.HttpRequest")

; The ContentType, HttpVerb, and Path properties should
; always be explicitly set.
$oReq.HttpVerb = "POST"
$oReq.Path = "/something"
$oReq.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.
$oReq.AddHeader "Accept","application/json"

; We'll use Chilkat's JSON API to create the JSON body of the HTTP request.
$oJson = ObjCreate("Chilkat.JsonObject")
$oJson.AppendString("username","my_username")
$oJson.AppendString("password","my_password")

$oVFactors = ObjCreate("Chilkat.JsonObject")
$oJson.AppendObject2("validation-factors",$oVFactors)

$oVArray = ObjCreate("Chilkat.JsonArray")
$oVFactors.AppendArray2("validationFactors",$oVArray)

$oFactorObj = ObjCreate("Chilkat.JsonObject")
$oVArray.AddObjectAt2(0,$oFactorObj)
$oFactorObj.AppendString("name","remote_address")
$oFactorObj.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
$oJson.EmitCompact = False
$oReq.LoadBodyFromString($oJson.Emit(),"utf-8")

; View the request that would be sent if HttpSReq was called:
Local $sRequestMime = $oReq.GenerateRequestText()
ConsoleWrite($sRequestMime & @CRLF)

; 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 HttpSReq
;    is called
