See more HTTP Examples

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"}
