將 Amazon 登入設定為身分集區 IdP

使用 Login with Amazon：Android

驗證 Amazon 登入之後，您可以在 TokenListener 介面 onSuccess 方法中將權杖傳遞給 Amazon Cognito 憑證提供者。程式碼看起來像這樣：

@Override
public void onSuccess(Bundle response) {
    String token = response.getString(AuthzConstants.BUNDLE_KEY.TOKEN.val);
    Map<String, String> logins = new HashMap<String, String>();
    logins.put("www.amazon.com", token);
    credentialsProvider.setLogins(logins);
}

使用 Login with Amazon：iOS - Objective-C

驗證 Amazon 登入之後，您可以透過 requestDidSucceed 方法將權杖傳遞給 Amazon Cognito 憑證提供者AMZNAccessTokenDelegate：

- (void)requestDidSucceed:(APIResult \*)apiResult {
    if (apiResult.api == kAPIAuthorizeUser) {
        [AIMobileLib getAccessTokenForScopes:[NSArray arrayWithObject:@"profile"] withOverrideParams:nil delegate:self];
    }
    else if (apiResult.api == kAPIGetAccessToken) {
        credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyLoginWithAmazon): apiResult.result };
    }
}}

使用 Login with Amazon：iOS - Swift

對 Amazon 登入進行身分驗證之後，您可以在 AMZNAccessTokenDelegate 的 requestDidSucceed 方法中，將權杖傳遞給 Amazon Cognito 憑證供應商：

func requestDidSucceed(apiResult: APIResult!) {
    if apiResult.api == API.AuthorizeUser {
        AIMobileLib.getAccessTokenForScopes(["profile"], withOverrideParams: nil, delegate: self)
    } else if apiResult.api == API.GetAccessToken {
        credentialsProvider.logins = [AWSCognitoLoginProviderKey.LoginWithAmazon.rawValue: apiResult.result]
    }
}

搭配 Amazon 使用登入： JavaScript

使用者以 Login with Amazon 進行驗證，並重新導向回您的網站之後，查詢字串中會提供 Login with Amazon access_token。請將該權杖傳遞至登入資料登入對應中。

AWS.config.credentials = new AWS.CognitoIdentityCredentials({
   IdentityPoolId: 'IDENTITY_POOL_ID',
   Logins: {
       'www.amazon.com': 'Amazon Access Token'
   }
});

使用 Login with Amazon：Xamarin

適用於 Android 的 Xamarin

AmazonAuthorizationManager manager = new AmazonAuthorizationManager(this, Bundle.Empty);

var tokenListener = new APIListener {
  Success = response => {
    // Get the auth token
    var token = response.GetString(AuthzConstants.BUNDLE_KEY.Token.Val);
    credentials.AddLogin("www.amazon.com", token);
  }
};

// Try and get existing login
manager.GetToken(new[] {
  "profile"
}, tokenListener);

適用於 iOS 的 Xamarin

在 AppDelegate.cs 中，插入下列內容：

public override bool OpenUrl (UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
{
    // Pass on the url to the SDK to parse authorization code from the url
    bool isValidRedirectSignInURL = AIMobileLib.HandleOpenUrl (url, sourceApplication);
    if(!isValidRedirectSignInURL)
        return false;

    // App may also want to handle url
    return true;
}

在 ViewController.cs 中，執行下列操作：

public override void ViewDidLoad ()
{
    base.LoadView ();

    // Here we create the Amazon Login Button
    btnLogin = UIButton.FromType (UIButtonType.RoundedRect);
    btnLogin.Frame = new RectangleF (55, 206, 209, 48);
    btnLogin.SetTitle ("Login using Amazon", UIControlState.Normal);
    btnLogin.TouchUpInside += (sender, e) => {
        AIMobileLib.AuthorizeUser (new [] { "profile"}, new AMZNAuthorizationDelegate ());
    };
    View.AddSubview (btnLogin);
}

// Class that handles Authentication Success/Failure
public class AMZNAuthorizationDelegate : AIAuthenticationDelegate
{
  public override void RequestDidSucceed(ApiResult apiResult)
    {
      // Your code after the user authorizes application for requested scopes
      var token = apiResult["access_token"];
      credentials.AddLogin("www.amazon.com",token);
    }

    public override void RequestDidFail(ApiError errorResponse)
    {
      // Your code when the authorization fails
      InvokeOnMainThread(() => new UIAlertView("User Authorization Failed", errorResponse.Error.Message, null, "Ok", null).Show());
    }
}
