I updated by Google Drive SDK references to 1.70 recently and updated all of my authentication code from using IAuthorizationState and the NativeApplicationClient to using UserCredentials, Drive.Auth.Store, and a DriveService object consistent with Google's "supported" method.
Everything working with my DriveService is working great. I can upload files, list files, create files and folders. Now I'm trying to figure out how to perform the simple act of downloading files by ID and I can't determine how I can leverage my new authentication code to support downloading. The SDK examples are referencing IAuthenticator but I'm not sure if that is a legacy object and my current project can't naturally reference it (missing a reference or perhaps isn't in 1.70).
I recognize that the Drive SDK may not actually have a method of downloading a file, but I'm very confused about how I can use my clean, new authentication store (Drive.Auth.Store) which has everything I should need to authenticate with the downloading action.
A point in the right direction would be most helpful! Thanks in advance for your help.

I have been running GDrive API v3 using our Node.js API for awhile now (1+ year), and everything has been functional for creating (drive.files.create) & reading (drive.files.get) DOCX files through the Google Drive API logic using a service account. Everything has been working perfectly fine.
Today I am trying to extend our infrastructure to handle some generic Google Docs files (rather than the existing DOCX stored within GDrive) using the same service account, but the GDrive API is now returning a 403 "Forbidden" error for these files specifically. I can't seem to figure out why there would be a difference in permissions for two file formats that are within the same service account (is the owner of both) and are using the same OAuth token system that I set up originally. The service account itself created the file, so I am a little shocked that it can't then access the same file using the GDrive API.
My question is, is it not possible to use GDrive API to access Google Doc files, even when the files are within a GDrive folder? I can't seem to find any definitive information online on whether we specifically have to use the Google Docs API to access Docs files (seems silly if true). If it is possible, is there an alternative SCOPE that I need to assign to this service account to access Google Docs items specifically? Right now the only SCOPE assigned is https://www.googleapis.com/auth/drive, which according to documentation should be enough to access all of our GDrive files.
I can share some code, but there is not exactly a lot more than what I explained above. I would like to not have to entirely re-do my GDrive OAuth permissions if possible, as that took me a long time in the first place, but if that is the only way, I would love to hear suggestions.
Thanks!
I have tried without much success to integrate my web application within the Google Drive UI (to open files). I cannot get the app to install using the OAuth scope https://www.googleapis.com/auth/drive.install.
I was wondering if anybody could share their Drive SDK configuration to see if I missed something. I tried installing my app using the Google API Console by selecting the Drive Integration to automatically authenticate. I also tried manually making the OAuth request using the google-api-client gem.
I always get the permissions dialog and I can see the following being requested: Add itself to Google Drive. I also get redirected back to my application like a normal OAuth request, but the application is never listed in Google Drive.
I have been requesting the following scopes:
https://www.googleapis.com/auth/drive.install
https://www.googleapis.com/auth/drive.file
profile
user
Allowing Import and these Secondary MIME Types:
application/vnd.google.drive.ext-type.html
text/html
I followed the documentation here: https://developers.google.com/drive/web/enable-sdk
Thanks in advance for any help!!
I was able to solve this by modifying my OAuth flow. It wasn't exchanging the authentication code for an access token before. Once I made it to that point everything worked as expected.
My issue was, that I didn't have this set:
Allowing Import and these Secondary MIME Types:
application/vnd.google.drive.ext-type.html text/html
I'm working with Google Spreadsheets, so I need a mime type that a sheet can be converted to, such as text/csv, see https://developers.google.com/drive/api/v3/integrate-open#open_and_convert_google_docs_in_your_app
I am pretty new to Google Drive SDk. After spend hours on the google drive sdk document and quick start app, I think I have known some basic concepts about it.
However, I have a easy but crucial question: how to integrate my code with Drive UI.
I mean I know I should enable Google Drive API and Google Drive SDK and do some configure staff. And I did.
I set up the MIME type that my app should be able to open and create, but it doesn't work. (I used the most easy one: plain/text: txt).
In fact, I think this is not the most serious problem. I am confused about how to integrate my code with Drive UI.
I mean the quick start app works fine, but it just simply upload a file. What if I want to perform some complicate action after user open a certain file with my app?
Ideally, I think it should redirect the user to my open URL and all the actions should go with that site, right?
(I am using Python, in case that could make any differences)
I am really confused. Excuse my chaos description, please.
Thanks in advance!
EDIT:
Thanks for the answering below! I think I need to detailed explain my needs from google drive sdk.
Basically, I want the user who have installed my app be able to open a certain file (which should be spreadsheet or txt) on google drive. Then it will redirect the user to my given Open URL (which I create a site by using google site). On that site, user should be able to view and import the content of file into a certain database. None of the operations above require any technique knowledges. I certainly can do this by writing python script and run it locally to import the content of files on google drive. However, there are two issues: first, I need to run it locally. I mean I did use the google drive api, but I didn't explore the real benefit of api; second, it is still a command line script, and has to be ran on linux.
I hope I have illustrated my request. And I appreciate any help in advance!
Install the client library:
pip install --upgrade google-api-python-client
Acquire an access token as explained on the Python Quickstart example. Init a Drive service to be able to talk to the API and authorize http transporter with your credentials. You need to make requests to get file metadata and file contents.
Retrieve file metadata:
http = httplib2.Http()
http = credentials.authorize(http)
drive_service = build('drive', 'v2', http=http)
f = drive_service.files().get(fileId=file_id).execute()
Retrieve file contents:
downloadUrl = f.get('downloadUrl')
f['content'] = drive_service._http.request(downloadUrl)
(Don't forget content retrieving request should be authorized and authenticated, that's why we use drive_service._http to make that request.
I am trying to fetch access token and refresh token using the document specified here. While doing so, I am faced with an issue:
java.lang.NoSuchMethodError: com.google.api.client.json.JsonFactory.fromInputStream(Ljava/io/InputStream;Ljava/lang/Class;)
Where can I find the jar which contains this class and method?
The Google Drive Java client library is based on the Google APIs Java client library. Make sure you download it as well. The zip contains the library and all its dependencies.
Also make sure that you don't have conflicting versions of the Google Apis Client library in your compile/classpath as this method is only available in later versions.
I'm working on a Google Drive interface for Emacs. The concept is that Emacs could provide a platform-agnostic way to load, modify and save text documents stored in Google Drive. I've registered my app and can authenticate with OAuth2 and get a file listing with the Docs List API, but when I try to execute an Insert with the Google Drive API, I see an error:
"The authenticated user has not installed the app with client id ..."
Reading further, it seems I need to publish my Emacs application in the Chrome Web Store to get access to the Drive API. That doesn't make sense to me...I noticed that there is a FUSE project in development for Google Drive, which suggests that native development is possible. When I skimmed the code, however, I didn't see a Chrome Web Store component to getting it working.
Am I trying to misuse the API, or is there an route to make this work that makes more sense?
EDIT:
According to Ali Afshar, of the Google Drive team, installation is no longer required to use this API. So what follows may no longer be relevant, but will be left for historical purposes.
So, first off the API does not support application development in the sense that we are both doing it, I wouldn't use the word native though. The good news is I have been doing some research and Google Drive is really just a rebranding of Google Docs. So the Google Docs API could be a good choice as well for the same purposes.
Anyway, here's the steps to solve the error: "The authenticated user has not installed the app with client id ..." Which is a 403 error, for the sake of this answer. These steps assume you have set up an app in the chrome web store as is required, and installed it. I am working on my local machine too, with my project: http://github.com/tom-dignan/gdrive-cli which I have gotten past this error, so I think you should keep plugging away at your emacs version, because I think we can make this work.
a. Open the Google APIs console.
b. Confirm you've already enabled the apis under "API Access" both the API and SDK for Google drive should be enabled. There you get your client secrets/api keys and such. I am almost positive you've done this already, so go ahead to C. (this is here for others who may have missed it)
c. In the left navigation bar, under "Drive SDK" you will need to do the following:
Add a "Support URL" (required)
Add at least a small 16x16 application icon (required)
Add "OAuth Client ID (Required)" under Drive Integration (I was just tinkering and this seems to be the key field.)
Add "Open URL (Required) URL to open for your app from the google drive UI."
Check off "Multiple File Support"
Add some MIME types and file extensions, "text/plain", and txt for example
Add the the auth scopes:
https://www.googleapis.com/auth/userinfo.email
https://www.googleapis.com/auth/userinfo.profile
Don't bother trying to add the auth scopes for Google Docs here, because it won't work. Google does not want us to use it that way because files that drive apps create should be private to that app. Integration with Google Docs will have to be separate.
Now I know you must be thinking "why do I have to add some of these..." It's because the form makes them required fields. In mine, I put a couple URLs that point to static HTML pages.
Once you've done the above, clean up your state and reinstall your chrome app. Then try your code again, and it should stop giving you a 403.
