# ------------------------------------------------------------------------
# The PostJson method is deprecated:

# responseObj is a CkHttpResponse
set responseObj [CkHttp_PostJson $http $url $jsonText]
if {[CkHttp_get_LastMethodSuccess $http] == 0} then {
    puts [CkHttp_lastErrorText $http]

delete_CkHttpResponse $responseObj

# ------------------------------------------------------------------------
# Do the equivalent using HttpStr.
# Your application creates a new, empty HttpResponse object which is passed 
# in the last argument and filled upon success.
