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"}

LOCAL lnSuccess
LOCAL loHttp
LOCAL loJson
LOCAL lcUrl
LOCAL loResp

lnSuccess = 0

loHttp = CreateObject('Chilkat.Http')
lnSuccess = 0

loJson = CreateObject('Chilkat.JsonObject')

* Build the following JSON:  {"greeting":"Hello World"}
loJson.UpdateString("greeting","Hello World")

* This URL echoes the contents of the request body, letting us view it.
lcUrl = "https://chilkatsoft.com/echo_request_body.asp"

* Send a POST with the JSON in the HTTP request body.
loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpJson("POST",lcUrl,loJson,"application/json",loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loJson
    RELEASE loResp
    CANCEL
ENDIF

? "Response Status Code: " + STR(loResp.StatusCode)

* 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.
? loHttp.LastHeader
? loResp.BodyStr

* 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"}
