Java Requires Chilkat v11.0.0+

Example: Http.HttpStr method

Shows how to use the HttpStr method to send an HTTP POST request with the text of a string as the request body. The 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"}
