HTTP PUT JSON

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.
