Occassional (OAuthException - #200) (#200) User must have accepted TOS

问题 I am confident my application is coded correctly (at least mostly), as it works about 98% of the time. However, about 2% of the time, I get what appears to be a valid auth token, but when I go to post a photo, I'm getting the following error "(OAuthException - #200) (#200) User must have accepted TOS". I have retry logic, but it gets the same error three times (so it's not a freak communication glitch). I use the URL facebook.com/dialog/oauth to get the token, and then I use the C# Facebook

Sign in with Facebook oauth, without full facebook.com access

阅读更多关于 Sign in with Facebook oauth, without full facebook.com access

问题 A web application I'm currently developing needs users to be able to sign in via Facebook OAauth. However the problem is, all these users are behind a firewall that blocks access to facebook.com (company policy). We've looked into several solutions to get around this, like; Putting a (squid) proxy between Facebook and the users. This could solve the problem since squid supports fine grained regex-based ACLs. However, most of the Facebooks OAuth strategy runs on www.facebook.com and inspecting

Refresh token and Access token in facebook API

阅读更多关于 Refresh token and Access token in facebook API

问题 When we do oauth2 on google api, we get an access token and a refresh token. Suppose I'm writing a service and I want to periodically poll for changes I can just use refresh token to get fresh access tokens every time the current access token gets invalidated. This is called offline access. Is there any way to do the same in facebook? Is there an offline access version similar to that of google api. Thanks. 回答1: For offline access, you need to exchange your short-lived access token for a new

Using OAuth for both development and production environments

阅读更多关于 Using OAuth for both development and production environments

I have seen other questions on SO about this ( here , here , and here ), but I am not satisfied with any of the solutions, so I am asking it again. I am starting a web application that will utilize OAuth from multiple providers (Google, Facebook, Twitter, Yahoo) for authentication. I am struggling to find a configuration suitable to use for both a local development environment and a production environment. The leading solutions I've found are to register multiple apps within each provider, receiving a different consumer key and secret for each: "My App Production" - with a callback URI to http

FB.getLoginStatus does not fires callback function

阅读更多关于 FB.getLoginStatus does not fires callback function

I have a difficult problem. Difficult means I searched through the net and StackOverflow as well the whole FBJS SDK documentation and haven't find answer. I am building a Page Tab application where I'd like to let fans to rsvp events. So I have to check if the user is logged in and if it doesn't I have to login. That sounds pretty easy, but FB.getLoginStatus doesn't fires callback function. This is the code excerpt: FB.init({ appId: window.appID, status: true, xfbml: true, cookie: true, oauth: true, channelUrl: 'http://example.com/fb/channel.html' }); and then I simply - of course after the

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Play Framework appending #= to redirect after Facebook auth via OAuth2? Has anyone else seen this happen? I am building a Facebook canvas app using the Facebook PHP SDK, and some Javascript. Now when I take the user through the OAuth authentication flow, I have noticed that the URL in the browser automatically gets appended with this "#_=_" , so my URL starts looking like this: http://apps.facebook.com
