I am trying build a page, where a user can login using his google id and can access Picasaweb albums.
I am using gdata-java-client-1.47.1.zip (downloaded from here), google-oauth-java-client-1.10.1-beta.zip (downloaded from here) and google-api-java-client-1.10.3-beta.zip (downloaded from here)
After setting up the OAuth2 workflow and getting the access token, I had created Credential object
return new GoogleCredential.Builder().setClientSecrets(CLIENT_ID, CLIENT_SECRET)
.setJsonFactory(jsonFactory).setTransport(transport).build().setAccessToken(gtresponse.getAccessToken()).setRefreshToken(gtresponse.getRefreshToken());
When I am trying to create the PicasawebService object and set OAuth2Credentials as mentioned in this link, I do NOT see a method setOAuth2Credentials in the list of methods available for PicasawebService object. I can only see setOAuthCredentials(parameters, signer) method available. Is this expected?
Not sure where I should go from here on how to access the web albums data? Kind of stuck! please help?
Thank you,
Satya
Try using PicasaClient as is done in this sample:
PicasaClient client = new PicasaClient(HTTP_TRANSPORT.createRequestFactory(credential));
You probably have to include PicasaClient, PicasaUrl and the model classes manually.
Another option would be to go down the already deprecated, but supported until April 2015, AuthSub way.

We need to read out distribution lists from a contact folder of a dedicated exchange/outlook mailbox (O365). The process must run as a service with no user interaction.
Unfortunately the Graph API does not support distribution lists (not even the Graph beta version does). Because of this we have to use another API - I tried using EWS.
I succeeded by granting full_access_as_app permission to our service. However this allows to read and modify ANY data in ANY mailbox which is a security risk. Granting this permission only to read out some distribution lists from one mailbox is not acceptable.
So I tried to use the ROPC flow that should allow authenticating a user and then accessing the mailbox with the permissions of this user. I followed the information here: How to get OAuth2 access token for EWS managed API in service/daemon application
(Btw I found this post linked in the discussion here: https://github.com/microsoftgraph/microsoft-graph-docs/issues/5659 which has some more information about the topic.)
I exactly followed the steps mentioned above but unfortunately this is not working: I always get a “401 Unauthorized” exception when doing the EWS calls (OAuth calls succeed) and no additional information.
According to https://developer.microsoft.com/en-us/graph/blogs/upcoming-changes-to-exchange-web-services-ews-api-for-office-365/ this is no longer working. So how can I read out distribution lists from a specific mailbox without giving full access and without an interactive login?
EDIT
Here as requested the full code:
string[] ewsScopes = { "https://outlook-tdf-2.office.com/EWS.AccessAsUser.All" };
IPublicClientApplication clientApplication = PublicClientApplicationBuilder.Create(appId).WithAuthority(AzureCloudInstance.AzurePublic, tenantId).Build();
NetworkCredential credentials = new NetworkCredential(appUsername, appPassword);
AuthenticationResult authResult = await clientApplication.AcquireTokenByUsernamePassword(ewsScopes, credentials.UserName, credentials.SecurePassword).ExecuteAsync().ConfigureAwait(false);
ExchangeService exchangeService = new ExchangeService
{
Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx"),
Credentials = new OAuthCredentials(authResult.AccessToken),
};
ItemView view = new ItemView(int.MaxValue)
{
PropertySet = new PropertySet(ItemSchema.Id),
};
SearchFilter.IsEqualTo filter = new SearchFilter.IsEqualTo(ItemSchema.ItemClass, "IPM.Contact");
FindItemsResults<Item> ewsResult = await exchangeService.FindItems(WellKnownFolderName.Contacts, filter, view).ConfigureAwait(false);
I have also tried with other scopes such as "https://outlook.office.com/EWS.AccessAsUser.All" or "https://outlook.office365.com/EWS.AccessAsUser.All" but without success. I feel the problem might be related to the scope? I can see that the Exchange legacy API that was listed in the Azure UI when adding permissions is now gone...?
The Scope in your code is wrong (I'm not sure where you got that from) it should be
string[] ewsScopes = { "https://outlook.office.com/EWS.AccessAsUser.All" };
Using your code with the scope you had gives a 401 error and if you look at the response headers of the EWS response it actually tells you that the scope is the issue eg
2000003;reason="The audience claim value is invalid for current resource. Audience claim is 'https://outlook-tdf-2.office.com/', request url is 'https://outlook.office365.com/EWS/Exchange.asmx' and resource type is 'Exchange'.";error_category="invalid_resource"
Using your code with the correct scope works fine
But then why is the option to add the Exchange Legacy permission (step 6 in the MS docu mentioned above) gone from the Azure UI?
Its hasn't been removed from the AzureUI they have just moved all the Exchange legacy permissions (including the ones used in the Exchange Admin cmdlets which isn't really a legacy API) under the Graph Permissions. Why they did this way and didn't communicate it well (I'll only just saw it today as well) I'm not sure.
Yesterday Nov 19th Microsoft has updated the documentation: https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-authenticate-an-ews-application-by-using-oauth
Following the new documentation it works (again). The main difference is to use the shortened scope "EWS.AccessAsUser.All" and not any of the full scopes found in many examples and posts such as “https://outlook.office.com/EWS.AccessAsUser.All”, “https://outlook.office365.com/EWS.AccessAsUser.All” etc.
Thank you MS for wasting my time.
Distribution groups are only exposed in Exchange PowerShell today, and are not currently supported via the Microsoft Graph API.

So, I'm very new to this. I got a generated json file from my google developer console that holds information like private keys, client id, token stuff, etc.
Now, I'm trying to use the Google Analytics Report V4 api. I put all my code into a concern, and when I run the code I get this error:
Google::Apis::AuthorizationError: Unauthorized
So I know that I have to authorize my app, but I'm not sure how. I have this json file which appears to have all the information I need to authenticate my app.
After some research, I know that (on the following code) I need to assign analytics.authorization to something, I just don't know to what.
analytics = Google::Apis::AnalyticsreportingV4::AnalyticsReportingService.new
analytics.authorization = ???
Do you know of any method I'm supposed to call that takes in the location of my json file as a parameter or something that can in turn, authorize my rails app?
Thank you so so much if you can help.
I know there are other questions like this. But they use omniauth with devise I think, and I can't do that. I already have a specific context in which users need to be logged in to my app, so logging in with google wouldn't work in my case. Also, other question/answers that don't involve omniauth and devise are outdated or don't have an accepted answer.
I have an endpoints API that I'm accessing with a Dart client library generated with discoveryapis_generator. All is well and good except that the generated library doesn't appear to reflect the authentication requirements of my API.
Is it only necessary to somehow create an authenticated http object to pass to my application's BrowserClient() constructor in the following line?
my_api = new MyApi(new BrowserClient());
Is the recommended method for creating the authenticated http object to use the googleapis_auth package as described here? Am I on the right track?
The authentication is not part of the API itself. It is actually the http client that will send the proper http header for user authentication. Assuming you use the standard google auth mechanism, you can use the package https://pub.dartlang.org/packages/googleapis_auth as you would for a standard Google API (Drive, etc...).
You will have to create a clientId (google console) and use BrowserOAuth2Flow to get an AuthClient (that extends http.client) and from then do new MyApi(authClient)
I have a (quite old) project where I override the standard behavior of google auth to allow specifying a userId (never really found the doc on that but it works) during authentication with a simple example that use the PlusApi to get the user name but it could work in a similar way for your own api. Maybe that could help https://github.com/alextekartik/tekartik_googleapis_auth.dart
I think you need at least the email scope when calling createImplicitBrowserFlow
There are also samples for using google apis that could help: https://github.com/dart-lang/googleapis_examples
Trying to access files in the private repositories of a Github organization of which I am a member, using the API. Tried a couple different ways so far:
1. If I use the username/password method --
curl -u "sashafklein:mypassword" https://api.github.com/repos/:org/:repo/git/trees/:file_sha
it works fine, but I'm trying to access the repos from a collaborative Rails app, so I don't want to publicize my github login credentials. I suppose creating a dummy GH account with access and using those credentials is possible, but it's definitely not ideal..
2. So I looked at the OAuth2 Secret/Key method in the API docs. But it doesn't work. If I curl the org repo url with my credentials as params in the url:
curl -i "https://api.github.com/orgs/:org/repos?private&client_id=<ID>&client_secret=<SECRET>"
Only the public repos show up. This may be a problem with how I'm passing params (passing "?private=true" should theoretically then return an empty list, but the list is identical and all public repos), but I'm following the docs.
3. So I got frustrated and took a look at these docs for getting a OAuth token, but I'm confused about how to alter it so that there's no user interface -- ie, so that my app has automatic access to the Github Orgs of which I am a member, without users of it having to do anything in particular.
Any ideas what I'm doing wrong with attempt 2, or how to get attempt 3 working automatically? I'm pretty stumped.
EDIT I think my client_id/secret are wrong, cause even when I use Octokit, it can't access the protected repos. Am I understanding this wrong? As me, I created an "Application" on Github for my Rails app, and I'm trying to use those credentials to access the org's private repos (to which I am a contributor) using the API.
In case anyone runs into this problem, here's the solution I found.
Apparently the client credentials I had weren't working. I think I didn't quite understand what they're for. The easiest way I could get this to work (ie, get permission for my rails app to access a private repo of which I was a member) was to use the username:password method (1, above).
So that my personal github credentials wouldn't be available to everyone using the app, I created a new dummy github account with access that serves exclusively as an api credentializer.
I am using Octokit with C# and encountered the same issue. After some investigation I found out it was a problem with my token permissions.
Token have scopes (https://developer.github.com/v3/oauth/#scopes) so to access private repositories you need 'repo' instead of 'public_repo' which I think was default.
This can be easily changed from Settings > Personal Access tokens > edit
I am trying to implement XPagesSBT on localhost.
I have followed this article http://heidloff.net/home.nsf/dx/12152011034545AMNHECAP.htm and the SBT document by Niklas and was trying to implement dropbox oAuth.
I have also placed http://localhost/XPagesSBT.nsf/ and http://localhost/WebSecurityStore.nsf in root folder
but still i get this error
Error while executing JavaScript action expression
Script interpreter error, line=1, col=26: Error calling method 'isAuthenticated()' on java class 'com.ibm.xsp.extlib.sbt.services.client.endpoints.DropboxEndpoint'
No application is registered with id XPagesSBT and provider Dropbox
if(!#Endpoint("dropbox").isAuthenticated()) {#Endpoint("dropbox").authenticate(true);}
do i need to make any other configuration /setup to XPagesSBT db? or it wont work with Localhost?
I don't remember exactly anymore but reading my blog entry you linked it says you shouldn't use Anonymous:
"Additionally there are a couple of security related settings which are important to understand. First of all you need to assign access to the document with the application keys to the ID with which you signed the two NSFs. In the screenshot above I've entered both OpenNTF servers and my own user ID. When you use the web UI to do this these names are added to the document in an authors field and a readers field.
In the last step you need to configure the ACL of the security store. Anonymous must not have access to this database. All users who you want to be able to use the Social Enabler OAuth functionality need to have author access. This is so that their user keys can be stored in this database so that they only have to do the OAuth dance once. "
It should work on localhost. It looks like a configuration issue with SBT not being able to read the security tokens from the websecuritystore.nsf . Did you create the Dropbox Application Key with an admin id and sign the websecuritystore with the correct id?
