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

success = True

# This example uses a previously obtained access token having permission for the 
# Google Drive scope. 
# See Get Google Drive OAuth2 Access Token

http = chilkat2.Http()

http.AuthToken = "GOOGLE_DRIVE_ACCESS_TOKEN"

# First we want to initiate the resumable upload.
# We send a POST to get a session URI, which will be used to upload the file, and resume if needed.

# Our POST will look like this:

# POST https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable HTTP/1.1
# Authorization: Bearer [YOUR_AUTH_TOKEN]          <-- Chilkat automatically adds this header because the AuthToken property was set.
# Content-Length: 38                               <-- Chilkat will automatically add this header.
# Content-Type: application/json; charset=UTF-8    <-- This is the type of this POST, and is specified in the call to PostJson3.
# X-Upload-Content-Type: application/zip           <-- The type of file we'll be uploading
# X-Upload-Content-Length: 1366807                 <-- The size of the file we'll be uploading
# 
# {
#   "name": "myObject"
# }

http.SetRequestHeader("X-Upload-Content-Type","application/zip")
http.SetRequestHeader("X-Upload-Content-Length","1366807")

json = chilkat2.JsonObject()
json.UpdateString("name","myZip")

# resp is a CkHttpResponse
resp = http.PostJson3("https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable","application/json",json)
if (http.LastMethodSuccess == False):
    print(http.LastErrorText)
    sys.exit()

statusCode = resp.StatusCode
if (statusCode != 200):
    print(resp.BodyStr)
    print("response status = " + str(statusCode))
    sys.exit()

# The session URI is in the "Location" response header:
sbSessionUri = chilkat2.StringBuilder()
sbSessionUri.Append(resp.GetHeaderField("Location"))
sessionUri = sbSessionUri.GetAsString()
print("Session URI: " + sessionUri)

# Here's a sample session URI:  https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&upload_id=AEnB2UrszR8lDqlo3mtXJw_0rYI_Hi1oVh1NPFcLfoyBq9NcSjk85kFopoZaVEgT38OSmLl0XsObPf4iCSJwHlrOvvIJQ_ckIQ

# -----------------------------------------------------------------------------
# The next step is to upload the file using the session URI:

# We'll send a PUT that looks like this:

# PUT https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&upload_id=xa298sd_sdlkj2 HTTP/1.1
# Content-Length: 1366807
# Content-Type: application/zip
# 
# [BYTES 0-1366806]

# First remove the X-Upload-Content-Type and X-Upload-Content-Length request headers we specified earlier, so they don't get sent with subsequent requests.
http.ClearHeaders()

# Because the file is likely large, we'll use SynchronousRequest which allows to to pass an HTTP request object where the body can be streamed directly from a file.
req = chilkat2.HttpRequest()

req.ContentType = "application/zip"
req.HttpVerb = "PUT"

url = chilkat2.Url()
url.ParseUrl(sessionUri)

req.Path = url.PathWithQueryParams
print("Path with Query Param: " + url.PathWithQueryParams)

# Specify that the request body is to be streamed directly from a file.
success = req.StreamBodyFromFile("qa_data/zips/big.zip")
if (success == False):
    print(req.LastErrorText)
    sys.exit()

# resp is a CkHttpResponse
resp = http.SynchronousRequest(url.Host,url.Port,url.Ssl,req)
if (http.LastMethodSuccess == False):
    print(http.LastErrorText)
    sys.exit()

print(resp.BodyStr)
print("response status = " + str(statusCode))

# Sample output:

# {
#  "kind": "drive#file",
#  "id": "1rx20i53eurtkVQ-RT7Ry8Ct85PgPYMET",
#  "name": "myZip",
#  "mimeType": "application/zip"
# }
# 
# response status = 200
