Host: chilkatsoft.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

Ruby

require 'chilkat'

success = false

http = Chilkat::CkHttp.new()
success = false

json = Chilkat::CkJsonObject.new()

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

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

# Send a POST with the JSON in the HTTP request body.
resp = Chilkat::CkHttpResponse.new()
success = http.HttpJson("POST",url,json,"application/json",resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print "Response Status Code: " + resp.get_StatusCode().to_s() + "\n";

# 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.
print http.lastHeader() + "\n";
print resp.bodyStr() + "\n";

# 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"}
