我已经在Xcode 6中集成了Facebook sdk(使用swift).在登录期间,我请求public_profile权限:

FBSession.openActiveSessionWithReadPermissions(["public_profile"], allowLoginUI: true, completionHandler: {
...
...

所以我请求用户的信息:

FBRequestConnection.startForMeWithCompletionHandler { (connection, user, error) -> Void in
...
...

为什么用户对象不包含个人资料图片？如何获取用户个人资料图片？它不是public_profile的一部分？

我得到以下信息:

2015-01-25 01:25:18.858 Test[767:23804] {
"first_name" = xxx;
gender = xxx;
id = xxxxxxxxx;
"last_name" = xxxxxx;
link = "https://www.facebook.com/app_scoped_user_id/xxxxxxxxx/";
locale = "xxxxx";
name = "xxxxxxx xxxxxxx";
timezone = 1;
"updated_time" = "2013-12-21T18:45:29+0000";
verified = 1;
}

PS:隐私的xxx

我使用最后一个FBSDK(使用swift)

// MARK: sign in with facebook

func signInWithFacebook()
{
    if (FBSDKAccessToken.currentAccessToken() != nil)
    {
        // User is already logged in, do work such as go to next view controller.
        println("already logged in ")
        self.returnUserData()

        return
    }
    var faceBookLoginManger = FBSDKLoginManager()
    faceBookLoginManger.logInWithReadPermissions(["public_profile", "email", "user_friends"], handler: { (result, error)-> Void in
        //result is FBSDKLoginManagerLoginResult
        if (error != nil)
        {
            println("error is \(error)")
        }
        if (result.isCancelled)
        {
            //handle cancelations
        }
        if result.grantedPermissions.contains("email")
        {
            self.returnUserData()
        }
    })
}

func returnUserData()
{
    let graphRequest …

我不明白为什么他们不是一个明确的教程或指南,所以我希望我的问题可以在这里得到解答.

因此,尝试通过Web Api注册来自Facebook或谷歌的用户.

问题是,在这个RegisterExternal方法上,这一行:

var info = await Authentication.GetExternalLoginInfoAsync();

它返回null,因此返回a BadRequest()

到目前为止我得到了什么:

在Startup.Auth.cs我已经知道了id和秘密,请注意我也尝试过使用Microsoft.Owin.Security.Facebook

var facebookOptions = new Microsoft.Owin.Security.Facebook.FacebookAuthenticationOptions
            {
                AppId = "103596246642104",
                AppSecret = "1c9c8f696e47bbc661702821c5a8ae75",
                Provider = new FacebookAuthenticationProvider()
                {
                    OnAuthenticated = (context) =>
                    {
                        context.Identity.AddClaim(new System.Security.Claims.Claim("urn:facebook:access_token", context.AccessToken, ClaimValueTypes.String, "Facebook"));

                        return Task.FromResult(0);
                    }
                },
            };
            facebookOptions.Scope.Add("email");
            app.UseFacebookAuthentication(facebookOptions);



            app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
            {
            ClientId = "328779658984-t9d67rh2nr681bahfusan0m5vuqeck13.apps.googleusercontent.com",
            ClientSecret = "ZYcNHxBqH56Y0J2-tYowp9q0",
            CallbackPath = new PathString("/api/Account/ManageInfo")
        });

额外的facebookOptions没有解决问题.

我能够从谷歌和Facebook检索access_token.我也可以使用此access_token进行身份验证api/Account/UserInfo

GET http://localhost:4856/api/Account/UserInfo
in the header:
Authorization: Bearer R9BTVhI0...

哪个回报: …
