Execution of authentication request returned unexpected result: 404 #716

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. After the "GA_Service.Credentials = new GDataCredentials (strGAUserName, 
strGAPassword);"
2.var token = GA_Service.QueryAuthenticationToken(); 
3. GA_Service.SetAuthenticationToken(token);

What is the expected output? What do you see instead?

It was working fine, but now i get this error after 10 times of data pull.

What version of the product are you using? On what operating system?
Google.GData.Analytics V 2.2.0.0

Please provide any additional information below.

I am having the very same problem - my code has been working for two years 
without any issues.  Same exception:

This is occurring on my production system, so it's a huge problem for us.

I am getting a similar issue. Getting 404'ed when it was working fine just 
prior to 14:53 PST. I'm using Google.GData.Spreadsheets 2.2.0.0

I take it you guys all use the GData API still? I have been digging around and 
it seems that there is a new API:

https://developers.google.com/drive/web/quickstart/quickstart-cs

I really hope that the old GData API is still supported or we'll have to 
rewrite everything. BTW the new Drive API is not supported by .Net 3.5 - so 
this is a huge disaster for me.

There is a note on the sheets API page 
(https://developers.google.com/google-apps/spreadsheets/authorize) saying that 
OAuth1.0 will be killed off on May 5th and you have to use the OAuth 2.0 
service.

Guys isn't it somehow connected with the information:
'OAuth 1.0 is no longer supported and will be disabled on May 5, 2015'
https://developers.google.com/google-apps/spreadsheets/authorize

Anyone migrate code to use OAuth 2.0 and thus solved the problem?

Clearly we'll need to use OAuth2 but the only examples I've run across use 
copy/pasting a URL into a web browser and retrieving it, and then pasting it 
into the command line:

https://developers.google.com/google-apps/spreadsheets/authorize

I'm running an application outside of a web browser, so that's not an option. 
We need to find an OAuth2 example that works without manually accepting a token.

I've managed to solve this by using this solution with Service Account with 
oAuth2.0 
http://stackoverflow.com/questions/13664731/accessing-older-gdata-apis-spreadshe
et-api-using-oauth-2-and-a-service-account

The solution:
1. Create Project and Google Service Account in 
https://console.developers.google.com/project
2. Generate your p12 key.
3. Allow APIs in Developer console you want to use (basically we are going to 
use old API, so you can skip this step, but just in case)
4. Use the code below (.NET Framework 4.5!):

using System.Security.Cryptography.X509Certificates;
using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Spreadsheets;
using Google.Apis.Auth.OAuth2;

string keyFilePath = @"C:\key.p12";    // found in developer console
string serviceAccountEmail = "youraccount@developer.gserviceaccount.com";   // 
found in developer console
var certificate = new X509Certificate2(keyFilePath, "notasecret", 
X509KeyStorageFlags.Exportable);

ServiceAccountCredential credential = new ServiceAccountCredential(new 
ServiceAccountCredential.Initializer(serviceAccountEmail) //create credential 
using certigicate
            {
                Scopes = new[] { "https://spreadsheets.google.com/feeds/" } //this scopr is for spreadsheets, check google scope FAQ for others
            }.FromCertificate(certificate));

credential.RequestAccessTokenAsync(System.Threading.CancellationToken.None).Wait
(); //request token

var requestFactory = new GDataRequestFactory("Some Name"); 
requestFactory.CustomHeaders.Add(string.Format("Authorization: Bearer {0}", 
credential.Token.AccessToken));

SpreadsheetsService myService = new SpreadsheetsService("You App Name"); 
//create your old service
myService.RequestFactory = requestFactory; //add new request factory to your 
old service

SpreadsheetQuery query = new SpreadsheetQuery(); //do the job as you done it 
before
SpreadsheetFeed feed = myService.Query(query);

Also don't forget to grant "youraccount@developer.gserviceaccount.com" access 
to your spreadsheet document as you grant permissions for usual users by 
pressing Share.

Looks like this is the right direction for me as well, but now i'm getting 
exception when I call Query method.

            var query = new SpreadsheetQuery();
            query.Title ="some title";
            var feed = Service.Query(query);//<- exception

Any idea what could be wrong, or what should I do to check it out?

GoogleCodeExporter commented 9 years ago 
Alright, I figured it out. Step by step instructions as follows - also see the 
code I provided below. FYI, this runs in .Net 3.5 and unlike the solution 
offered previously there are no new dependencies. You should be up and running 
in no time.

1. If you haven't yet create your OAuth 2.0 credentials - I assume you already 
know how to get those but here:
   a) Log into your Google developer console: http://console.developers.google.com
   b) Create a project
   c) Create your credentials - use 'installed application'
   d) add the APIs that you need - I think Drive API is definitely required. I also added Drive SDK just in case.
2. Copy the code below into VS and edit the first Main() method with your 
client key and secret key. 
3. Run the app and copy both the new access token and the refresh token. Put 
those and your remaining credentials into the second Main() method below.
4. You now should be able to run the second Main() method (just reverse the 
naming). From now on that will be all you need - there is no need to re-run the 
first Main() method.

BTW, the first Main() method below was found here: 
https://developers.google.com/google-apps/spreadsheets/authorize

@Alex - yeah, saw that - brilliant and thanks for doing that. I found a 
solution that works for me. Not sure why Sangeeth and Fernando are still having 
issues - just follow the steps outlined and that ought to fix it.

Hi, evilstee... your solution looks pretty good, well commented, etc. We have 
the user visiting a URL manually (outside our application, via web browser) and 
pasting in the "authorization code" that he receives from Google OAuth. I am 
wondering if that can be automated? In my case, I know the user's Google login 
and password because... the user is me! It's a personal app just for me. I 
would like to automate that exchange and skip the manual copy-and-paste of the 
authorization code. Any ideas?

GoogleCodeExporter commented 9 years ago 
w3jgvo - you need to use Service Account to automate it. Check #33, this does 
not require manual copy-paste.

I implement the solution from #33 in Script task in SSIS, but ny execute i 
receive message "Could not load file or assembly 
'Google.Apis.Auth.PlatformServices, Version=1.9.1.12399, Culture=neutral, 
PublicKeyToken=null' or one of its dependencies. The system cannot find the 
file specified."

i think it because the reference Google.Apis.Auth.PlatformServices from Nuget 
has not strong name and cannot install to GAC.

Please help me, what need I do?

Thanks #31 for the solution provided. This works fine for me for accessing 
docs/spreadsheets.
However, I am getting the following error when I try to upload a document to 
the google drive:
"When performing a write operation with AllowWriteStreamBuffering set to false, 
you must either set ContentLength to a non-negative number or set SendChunked 
to true."

My code for uploading documents is:

GOAuth2RequestFactory requestFactory = RefreshAuthenticate();   
DocumentsService service = new 
DocumentsService("MyDocumentsListIntegration-v1"); service.RequestFactory = 
requestFactory; 
DocumentEntry entry = 
service.UploadDocument("C:\TempGoogleDocFolder\Test.docx", "Test");

The RefreshAuthenticate() function is coded as described above in #31.

Any ideas what is causing this or how it can be resolved?

#43 It can't find the new dlls. I resolved this by copying them to the Binn 
folder of the DTS execution program (default: C:\Program Files (x86)\Microsoft 
SQL Server\120\DTS\Binn\). I believe by registering them in the GAC this 
problem would also be resolved.

#33 - Does anybody know how to get this working with the SpreadsheetService 
from the python gdata libraries?

I've got this far:

    flow = OAuth2WebServerFlow(CLIENT_ID, CLIENT_SECRET, OAUTH_SCOPE,
                               redirect_uri=REDIRECT_URI)
    authorize_url = flow.step1_get_authorize_url()
    code = raw_input('Enter verification code: ').strip()
    credentials = flow.step2_exchange(code)

But I can't see how to use the credentials with SpreadsheetService.  The 
examples in the docs show how to use the credentials with the Drive API, like 
this:

    # Create an httplib2.Http object and authorize it with our credentials
    http = httplib2.Http()
    http = credentials.authorize(http)

    drive_service = build('drive', 'v2', http=http)

But again SpreadsheetService doesn't seem to have a way to set the authorized 
http object.

Any clues much appreciated.
