Demonstrates how to send a JSON PUT and get the JSON response body. Tcl

load ./chilkat.dll

set success 0

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

set req [new_CkHttpRequest]

set http [new_CkHttp]

# The PUT request to be sent will look like this:

# PUT /request HTTP/1.1
# Content-Type: application/jsonrequest
# Cookie: JSESSIONID=1234
# Content-Encoding: identity
# Host: json.penzance.org
# Accept: application/jsonrequest
# Accept-Encoding:
# Content-Length: 72
# 
# {"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...)
CkHttp_put_AcceptCharset $http ""
CkHttp_put_UserAgent $http ""
CkHttp_put_AcceptLanguage $http ""

# Suppress the Accept-Encoding header by disallowing 
# a gzip response:
CkHttp_put_AllowGzip $http 0

# If a Cookie needs to be added...
CkHttp_SetRequestHeader $http "Cookie" "JSESSIONID=1234"

# Add the Content-Encoding: identity header.
CkHttp_SetRequestHeader $http "Content-Encoding" "identity"

# Modify the default "Accept" header:
CkHttp_put_Accept $http "application/jsonrequest"

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

# 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.
