在Google App Engine中访问Google云端硬盘文件[共享链接]

Question

I have an android app that saves an image into the Google Drive and shares the weblink to my Google App Engine server (python).

    // Create client
    mGoogleApiClient = new GoogleApiClient.Builder(mContext)
        .addApi(Drive.API)
        .addScope(Drive.SCOPE_FILE)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .build();

   // handling results after uploading
   final DriveOperationResult<Metadata> driveOperationResultHandler = new DriveOperationResult<Metadata>() {

    @Override
    public void onDriveOperationSucceeded(Metadata result) {
        try {
            // Successfully fetched metadata
            onSuccess(driveId,
                      result.getOriginalFilename(),
                      result.getWebContentLink(),
                      result.getWebViewLink(),
                      result.getAlternateLink(),
                      result.getEmbedLink());
        } finally {
            mGoogleDriveClient.disconnectAsync();
        }
    }

Note: result.getEmbedLink() always returns null. Also, result.getAlternateLink() and result.getWebContentLink() are not accessible. I am using Google Drive Android API.

I need to post the link to another server from the google app engine. How do I get a shareable link from google app engine [python] or android?

or

How do I change the permission on the link so that anyone with the link can read?

In python, you must do something like this

@decorator.oauth_required
def get(self):
    try:
        http = decorator.http()
        service = discovery.build("drive", "v2", http=http)

        # Make the list of every files in the user's Drive
        # Take every fields we will need after
        fields = "items(id,title,,alternateLink)
        list = service.files().list(fields=fields).execute()

Then use the alternateLink property to get a link that can be shared for opening the file in the relevant Google editor or viewer
