load ./chilkat.dll

set success 0

set http [new_CkHttp]

set success 0

# This example will send an HTTP POST with the body of the HTTP request containing JSON.

# Create the following JSON: { "name": "Harry", "state": "FL" }

set json [new_CkJsonObject]

CkJsonObject_UpdateString $json "name" "Harry"
CkJsonObject_UpdateString $json "state" "FL"

# Specify the details of the request
set req [new_CkHttpRequest]

# Send the charset attribute in the HTTP request header.
CkHttpRequest_put_SendCharset $req 1
CkHttpRequest_put_Charset $req "utf-8"

# Send the POST
# You can send the POST to the URL below.  
# The response will contain the raw body of the request that was sent.
# (i.e. everything except the HTTP request header).

set resp [new_CkHttpResponse]

set success [CkHttp_HttpReq $http "https://www.chilkatsoft.com/echo_request_body.asp" $req $resp]

# Examine the HTTP request header we sent:
puts [CkHttp_lastHeader $http]

# The response body contains the raw content of the HTTP request body we sent.
puts [CkHttpResponse_bodyStr $resp]
