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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X PATCH --data-binary @JSON_FILE_NAME \
*   -H "Authorization: Bearer OAUTH2_TOKEN" \
*   -H "Content-Type: application/json" \
*   "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME"

* Use the following online tool to generate HTTP code from a CURL command
* Convert a cURL Command to HTTP Source Code

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBdRequestBody = CreateObject('Chilkat.BinData')
lnSuccess = loBdRequestBody.LoadFile("JSON_FILE_PATH")
IF (lnSuccess <> 1) THEN
    ? "Failed to load JSON_FILE_PATH"
    RELEASE loHttp
    RELEASE loBdRequestBody
    CANCEL
ENDIF

* Adds the "Authorization: Bearer OAUTH2_TOKEN" header.
loHttp.AuthToken = "OAUTH2_TOKEN"

loResp = loHttp.PBinaryBd("PATCH","https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME",loBdRequestBody,"application/json",0,0)
IF (loHttp.LastMethodSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loBdRequestBody
    CANCEL
ENDIF

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponseBody = CreateObject('Chilkat.StringBuilder')
loResp.GetBodySb(loSbResponseBody)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJResp = CreateObject('Chilkat.JsonObject')
loJResp.LoadSb(loSbResponseBody)
loJResp.EmitCompact = 0
