loSb = CreateObject('Chilkat.StringBuilder')
loSb.Append('{"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 contents of the StringBuilder in the HTTP request body.
loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpSb("POST",lcUrl,loSb,"utf-8","application/json",loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loSb
    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"}
