http = chilkat.CkHttp()

#  Sends a POST equivalent to the following CURL command:

#  curl -X POST https://sandbox.plaid.com/institutions/get \
#    -H 'content-type: application/json' \
#    -d '{
#      "client_id": String,
#      "secret":String,
#      "count": Number,
#      "offset": Number
#    }'

#  Suppress some default headers that would automatically added..

# task is a CkTask
task = http.PostJson2Async("https://sandbox.plaid.com/institutions/get","application/json",jsonBody)

success = task.Run()
if (not success):

#  The application is now free to do anything else
#  while the HTTP POST is in progress

#  For this example, we'll simply sleep and periodically
#  check to see if the HTTP POST is finished.
while task.get_Finished() != True :
    #  Sleep 100 ms.
    task.SleepMs(100)

#  When we get here, the task is either finished successfully or not, or was canceled/aborted.

#  If the task was "canceled", it was canceled prior to actually starting.  This could
#  happen if the task was canceled while waiting in a thread pool queue to be scheduled by Chilkat's
#  background thread pool scheduler.

#  If the task was "aborted", it indicates that it was canceled while running in a background thread.
#  The ResultErrorText will likely indicate that the task was aborted.

#  If the task "completed", then it ran to completion, but the actual success/failure of the method
#  is determined by getting the result of the underlying method call.
#  A task status of 7 indicates completion.
if (task.get_StatusInt() != 7):
    print("Task did not complete.")
    print("task status: " + task.status())

    sys.exit()

#  When called synchronously, the PostJson2 method returns an HTTP response object,
#  unless the method failed and there was no response to be had.
#  Check to see if PostJson2 method failed (and thus there is no response object).
if (task.get_TaskSuccess() == False):
    print("The underlying task failed, and there is no HTTP response object.")
    print("The LastErrorText for the underlying method call is:")

    sys.exit()

#  To get the HTTP response object, create a new instance and load it with the result from the task.
