(CkPython) Send JSON REST Request, Get JSON Response

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON).

# This example will create a bucket in Google Cloud Storage.

# It requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

gAuth = chilkat.CkAuthGoogle()
# Obtain an access token as shown in one of the following examples:
# See Get Access Token using a Service Account JSON Key
# See Get Access Token using a P12 File

rest = chilkat.CkRest()

# Connect using TLS.
bAutoReconnect = True
success = rest.Connect("www.googleapis.com",443,True,bAutoReconnect)

# Provide the authentication credentials (i.e. the access key)
success = rest.SetAuthGoogle(gAuth)

# Build the JSON request body for creating a bucket.
# The only required property is the "name", but we'll add more
# to make a better example..
jsonReqBody = chilkat.CkJsonObject()
success = jsonReqBody.AddStringAt(-1,"name","chilkat-bucket-c")
success = jsonReqBody.AddStringAt(-1,"kind","storage#bucket")
success = jsonReqBody.AddStringAt(-1,"location","US")
success = jsonReqBody.AddObjectAt(-1,"versioning")

# pObjVersioning is a CkJsonObject
pObjVersioning = jsonReqBody.ObjectOf("versioning")
success = pObjVersioning.AddBoolAt(-1,"enabled",True)

# Show the HTTP request body we'll be sending.
print(jsonReqBody.emit())

# Add the required query parameter.
# See https://cloud.google.com/storage/docs/json_api/v1/buckets/insert
success = rest.AddQueryParam("project","chilkattest-1050")

# Add the Content-Type HTTP request header.
success = rest.AddHeader("Content-Type","application/json; charset=UTF-8")

jsonResponseStr = rest.fullRequestString("POST","/storage/v1/b",jsonReqBody.emit())
if (rest.get_LastMethodSuccess() != True):
    print(rest.lastErrorText())
    sys.exit()

# Show the JSON response.  (See below for a sample JSON response.)
print("Json Response: " + jsonResponseStr)
