如何将 facebook 用户添加到 aws cognito？ - android
How to add facebook user to aws cognito? - android
我有点困惑。我能够使用 facebook sdk 设置 Facebook 登录按钮。接下来，我想将用户添加到 cognito 中，但指南告诉我这样做：
Map<String, String> logins = new HashMap<String, String>();
logins.put("graph.facebook.com", AccessToken.getCurrentAccessToken().getToken());
credentialsProvider.setLogins(logins);
我做到了，我没有看到用户隐身。我很困惑，"federated authentication" 是什么意思？我想要完成的是：
1.User 通过 Facebook 注册
2.Oncefacebook登录成功，我想将该用户加入认知
这是我当前的代码：
private void setFacebookButton()
{
Log.d("MY_FACEBOOK","setting up callbackManager");
callbackManager = CallbackManager.Factory.create();
loginButton.setReadPermissions("user_friends");
loginButton.setReadPermissions("public_profile");
loginButton.setReadPermissions("email");
loginButton.setReadPermissions("user_birthday");
// If using in a fragment
loginButton.setFragment(this);
// Callback registration
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.d("MY_FACEBOOK","login success!");
Map<String, String> logins = new HashMap<String, String>();
logins.put("graph.facebook.com", AccessToken.getCurrentAccessToken().getToken());
SetLoginsAsyncTask loginsAsyncTask = new SetLoginsAsyncTask(logins);
loginsAsyncTask.execute();
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
}
});
}
public class SetLoginsAsyncTask extends AsyncTask<Void,Void,Void>
{
private Map<String,String> logins = new HashMap<>();
public SetLoginsAsyncTask(Map<String,String> logins)
{
this.logins = logins;
}
@Override
protected Void doInBackground(Void... params)
{
myCognito.getCredentialsProvider().setLogins(logins);
myCognito.getCredentialsProvider().refresh();
String testing = myCognito.getCredentialsProvider().getCredentials().getSessionToken();
if(testing != null)
{
Log.d("MY_FACEBOOK","testing is " + testing);
}
else
{
Log.d("MY_FACEBOOK","testing is null");
}
return null;
}
@Override
public void onPostExecute(Void var)
{
}
}
所以我有点困惑，Facebook 登录按钮后的下一步是什么 returns 你是用户和他们的名字、姓氏、电子邮件等。我想将该用户添加到 Cognito 中，然后得到确认。
希望有人能用正确的步骤和代码来澄清。

这取决于您使用的 Android 版本的 AWS SDK。 2.6.0 中引入了适用于 Android 的 AWS Auth SDK。
- 将以下代码段添加到 AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"
<!-- . . . -->
<activity
android:name="com.facebook.FacebookActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="@string/fb_login_protocol_scheme" />
</intent-filter>
</activity>
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id" />
- 在gradle中导入以下依赖项。
compile 'com.android.support:support-v4:24.+'
compile ('com.amazonaws:aws-android-sdk-auth-facebook:2.6.+@aar') { transitive = true; }
// Dependencies for the SDK Sign-in prompt UI library
compile 'com.android.support:appcompat-v7:24.+'
compile ('com.amazonaws:aws-android-sdk-auth-ui:2.6.+@aar') { transitive = true; }
- 执行以下导入：
import com.amazonaws.mobile.config.AWSConfiguration; <br/>
import com.amazonaws.mobile.auth.core.IdentityManager; <br/>
import com.amazonaws.mobile.auth.facebook.FacebookSignInProvider; ; <br/>
import com.amazonaws.mobile.auth.core.IdentityManager;<br/>

import com.amazonaws.mobile.auth.ui.SignInActivity;<br/>
import com.amazonaws.mobile.auth.facebook.FacebookButton;<br/>
import com.amazonaws.mobile.auth.core.DefaultSignInResultHandler;<br/>
- 在 strings.xml
中添加您的 FB App ID
<string name="facebook_app_id">1231231231232123123</string>
<string name="fb_login_protocol_scheme">fb1231231231232123123</string>
- 在 Application.java
中注册 Facebook SignInProvider
private void initializeApplication() {
AWSConfiguration awsConfiguration = new AWSConfiguration(getApplicationContext());
// If IdentityManager is not created, create it
if (IdentityManager.getDefaultIdentityManager() == null) {
IdentityManager identityManager =
new IdentityManager(getApplicationContext(), awsConfiguration);
IdentityManager.setDefaultIdentityManager(identityManager);
}
// Add Facebook as Identity Provider.
IdentityManager.getDefaultIdentityManager().addSignInProvider(
FacebookSignInProvider.class);
FacebookSignInProvider.setPermissions("public_profile");
// . . .
}
