require 'chilkat'

req = Chilkat::CkHttpRequest.new()
http = Chilkat::CkHttp.new()

#  Any string unlocks the component for the 1st 30 days.
success = http.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print http.lastErrorText() + "\n";
    exit
end

#  This example duplicates the HTTP POST shown at
#  http://json.org/JSONRequest.html

#  Specifically, the request to be sent looks like this:
#  
POST /request HTTP/1.1
Accept: application/jsonrequest
Content-Encoding: identity
Content-Length: 72
Content-Type: application/jsonrequest
Host: json.penzance.org

{"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}


#  First, remove default header fields that would be automatically
#  sent.  (These headers are harmless, and shouldn't need to
#  be suppressed, but just in case...)
http.put_AcceptCharset("")
http.put_UserAgent("")
http.put_AcceptLanguage("")
#  Suppress the Accept-Encoding header by disallowing
#  a gzip response:
http.put_AllowGzip(false)

#  If a Cookie needs to be added, it may be added by calling
#  AddQuickHeader:
http.AddQuickHeader("Cookie","JSESSIONID=1234")

jsonText = "{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}"

#  To use SSL/TLS, simply use "https://" in the URL.

#  IMPORTANT: Make sure to change the URL, JSON text,
#  and other data items to your own values.  The URL used
#  in this example will not actually work.

# resp is a CkHttpResponse
resp = http.PostJson("http://json.penzance.org/request",jsonText)
if (resp == nil )
    print http.lastErrorText() + "\n";
else
    #  Display the JSON response.
    print resp.bodyStr() + "\n";
end
