*  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_9_5_0.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_9_5_0.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]"

loHttp = CreateObject('Chilkat_9_5_0.Http')
loHttp.AuthToken = loSbToken.GetAsString()

loHttp.SetUrlVar("project_id","chilkat-176611")
lcUrl = "https://www.googleapis.com/storage/v1/b?project={$project_id}"
loResp = loHttp.PostJson3(lcUrl,"application/json",loJson)
IF (loHttp.LastMethodSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loSbToken
    RELEASE loJson
    RELEASE loHttp
    CANCEL
ENDIF

lnResponseCode = loResp.StatusCode
IF (lnResponseCode = 401) THEN
    ? loResp.BodyStr
    ? "If invalid credentials, then it is likely the access token expired."
    ? "Your app should automatically fetch a new access token and re-try."
    RELEASE loResp
    RELEASE loSbToken
    RELEASE loJson
    RELEASE loHttp
    CANCEL
ENDIF

? "Response code: " + STR(lnResponseCode)
? "Response body"
? loResp.BodyStr

*  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_9_5_0.JsonObject')
loJsonResp.Load(loResp.BodyStr)

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

RELEASE loResp

*  Parse the date/time created.
loDt = CreateObject('Chilkat_9_5_0.CkDateTime')
loDt.SetFromTimestamp(loJsonResp.StringOf("timeCreated"))
*  ...
