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

* This example uses a previously obtained access token having permission for the 
* scope "https://www.googleapis.com/auth/cloud-platform"

* In this example, Get Google Cloud Storage OAuth2 Access Token, 
* the service account access token was saved to a text file.  This example fetches the access token from the file..
loSbToken = CreateObject('Chilkat.StringBuilder')
loSbToken.LoadFile("qa_data/tokens/googleCloudStorageAccessToken.txt","utf-8")

* ---- Step 1
* Create a JSON that contains the following information, replacing [VALUES_IN_BRACKETS] with the appropriate values:

* {
*   "name": "[BUCKET_NAME]",
*   "location": "[BUCKET_LOCATION]",
*   "storageClass": "[STORAGE_CLASS]"
* }

loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("name","chilkat-ocean")
loJson.UpdateString("location","us")
loJson.UpdateString("storageClass","multi_regional")

* ---- Step 2
* Send a POST equivalent to this curl command

* curl -X POST --data-binary @[JSON_FILE_NAME].json \
*      -H "Authorization: Bearer [OAUTH2_TOKEN]" \
*      -H "Content-Type: application/json" \
*      "https://www.googleapis.com/storage/v1/b?project=[PROJECT_ID]"

lnResponseCode = loResp.StatusCode
IF (lnResponseCode = 401) THEN

    ? "If invalid credentials, then it is likely the access token expired."
    ? "Your app should automatically fetch a new access token and re-try."

? "Response code: " + STR(lnResponseCode)
? "Response body"

* A successful response looks like this:
* Response code: 200
* Response body
* {
*  "kind": "storage#bucket",
*  "id": "chilkat-ocean",
*  "selfLink": "https://www.googleapis.com/storage/v1/b/chilkat-ocean",
*  "projectNumber": "933037264567",
*  "name": "chilkat-ocean",
*  "timeCreated": "2017-08-13T12:27:10.811Z",
*  "updated": "2017-08-13T12:27:10.811Z",
*  "metageneration": "1",
*  "location": "US",
*  "storageClass": "MULTI_REGIONAL",
*  "etag": "CAE="
* }
* 

* Parse the JSON response:
loJsonResp = CreateObject('Chilkat.JsonObject')
loJsonResp.Load(loResp.BodyStr)

? "name: " + loJsonResp.StringOf("name")
? "timeCreated: " + loJsonResp.StringOf("timeCreated")

* Parse the date/time created.
loDt = CreateObject('Chilkat.CkDateTime')
loDt.SetFromTimestamp(loJsonResp.StringOf("timeCreated"))
* ...
