登录Facebook应用程序并授权我的应用程序后，如何正确获取访问令牌和其他信息？ [Android]产品 [英] How can I get Access Token and other info correctly after logging in Facebook App and authorizing my app? [Android]
问题描述
我正在使用这个。在我的 authorized（）方法中的 Facebook.java 中，我调用 startSingleSignOn 和 startDialogAuth ，我使用 DEFAULT_AUTH_ACTIVITY_CODE 而不是 FORCE_DIALOG_AUTH
I'm using this. In my Facebook.java in my authorized() method I call startSingleSignOn and startDialogAuth, I'm using the DEFAULT_AUTH_ACTIVITY_CODE instead of FORCE_DIALOG_AUTH
public void authorize（Activity activity，String [] permissions，
int activityCode，final DialogListener listener）{
public void authorize(Activity activity, String[] permissions, int activityCode, final DialogListener listener) {
boolean singleSignOnStarted = false;
mAuthDialogListener = listener;
// Prefer single sign-on, where available.
if (activityCode >= 0) {
singleSignOnStarted = startSingleSignOn(activity, mAppId,
permissions, activityCode);
}
// Otherwise fall back to traditional dialog.
if (!singleSignOnStarted) {
startDialogAuth(activity, permissions);
}
}
我注意到在我的 startDialogAuth 它设置 AccessToken 和 AccessExpires
I noticed that in my startDialogAuth it sets the AccessToken and AccessExpires
private void startDialogAuth(Activity activity, String[] permissions) {
Bundle params = new Bundle();
if (permissions.length > 0) {
params.putString("scope", TextUtils.join(",", permissions));
}
CookieSyncManager.createInstance(activity);
dialog(activity, LOGIN, params, new DialogListener() {
public void onComplete(Bundle values) {
// ensure any cookies set by the dialog are saved
CookieSyncManager.getInstance().sync();
setAccessToken(values.getString(TOKEN));
setAccessExpiresIn(values.getString(EXPIRES));
if (isSessionValid()) {
Util.logd("Facebook-authorize", "Login Success! access_token="
+ getAccessToken() + " expires="
+ getAccessExpires());
mAuthDialogListener.onComplete(values);
} else {
mAuthDialogListener.onFacebookError(new FacebookError(
"Failed to receive access token."));
}
}
public void onError(DialogError error) {
Util.logd("Facebook-authorize", "Login failed: " + error);
mAuthDialogListener.onError(error);
}
public void onFacebookError(FacebookError error) {
Util.logd("Facebook-authorize", "Login failed: " + error);
mAuthDialogListener.onFacebookError(error);
}
public void onCancel() {
Util.logd("Facebook-authorize", "Login canceled");
mAuthDialogListener.onCancel();
}
});
}
在 startSingleSignOn 它看起来像这样
private boolean startSingleSignOn(Activity activity, String applicationId,
String[] permissions, int activityCode) {
boolean didSucceed = true;
Intent intent = new Intent();
intent.setClassName("com.facebook.katana",
"com.facebook.katana.ProxyAuth");
intent.putExtra("client_id", applicationId);
if (permissions.length > 0) {
intent.putExtra("scope", TextUtils.join(",", permissions));
}
// Verify that the application whose package name is
// com.facebook.katana.ProxyAuth
// has the expected FB app signature.
if (!validateActivityIntent(activity, intent)) {
return false;
}
mAuthActivity = activity;
mAuthPermissions = permissions;
mAuthActivityCode = activityCode;
try {
activity.startActivityForResult(intent, activityCode);
} catch (ActivityNotFoundException e) {
didSucceed = false;
}
return didSucceed;
}
我想知道它在哪里设置访问令牌这是登录时需要的，我面临的问题是用户已经安装了一个 Facebook应用程序并已经授权我的应用程序，它将只显示一个对话框（加载），并显示一个白色屏幕，然后关闭，但没有发生任何事情。它没有从记录的 Facebook应用程序获取用户的信息。但是当用户没有 Facebook应用程序时，它会显示WebView并且正常工作，它正确登录。在调试的时候我也注意到它不进入我的函数 LoginDialogListener 这里它实现 Facebook.DialogListener 有安装的是Facebook应用程序）也许是因为在 startSingleSignOn 它不调用 CookieSyncManager.createInstance（activity）;
对话框（活动，登录，参数，新的DialogListener（）{
I'm wondering where it sets the Access Token that is needed when logs-in, I'm facing the problem where the user has a Facebook app installed and already authorized my app, it will only show a dialog (Loading) and display a white screen then dismiss but nothing happen next. It doesn't get the user's information from the logged Facebook app. But when the user doesn't have a Facebook app it displays the WebView and just working fine, it logs in correctly. While debugging it I also notice that it doesn't go inside my function LoginDialogListener here it implements Facebook.DialogListener (when there is facebook app installed) maybe because in startSingleSignOn it doesn't call CookieSyncManager.createInstance(activity);
dialog(activity, LOGIN, params, new DialogListener() {
这里是我的 code>代码，它调用 facebook.authorize
public void setFacebookConnection() {
facebook = new Facebook(Constants.FACEBOOK_APP_ID);
facebookAsyncRunner = new AsyncFacebookRunner(facebook);
facebook.authorize(this, Constants.FACEBOOK_PERMISSIONS, new LoginDialogListener());
}
private class LoginDialogListener implements Facebook.DialogListener {
public void onComplete(Bundle values) {
Log.d(TAG, "LoginONComplete");
String token = facebook.getAccessToken();
long token_expires = facebook.getAccessExpires();
Log.d(TAG, "AccessToken: " + token);
Log.d(TAG, "AccessExpires: " + token_expires);
if (isPublishStreamAuthorized()) {
facebookSharedPreferences = PreferenceManager
.getDefaultSharedPreferences(context);
facebookSharedPreferences
.edit()
.putLong(Constants.FACEBOOK_ACCESS_EXPIRES,
token_expires).commit();
facebookSharedPreferences.edit()
.putString(Constants.FACEBOOK_ACCESS_TOKEN, token)
.commit();
facebookAsyncRunner.request("me", new IDRequestListener());
} else {
logoutFacebook();
}
}
public void onFacebookError(FacebookError e) {
Log.d(TAG, "FacebookError: " + e.getMessage());
}
public void onError(DialogError e) {
Log.d(TAG, "Error: " + e.getMessage());
Toast.makeText(getApplicationContext(), Constants.NO_INTERNET_CONNECTION,
Toast.LENGTH_LONG).show();
}
public void onCancel() {
Log.d(TAG, "OnCancel");
logoutFacebook();
}
}
似乎我的 facebook.getAccessToken（）; 在我的活动中返回null，因为尝试调用 setFacebookConnection（）调用 facebook.authorize（）
It seems that my facebook.getAccessToken(); in my activity returns null, as tried calling in my setFacebookConnection() after calling facebook.authorize()
你能帮我吗？我需要尽快解决这个问题。非常感谢你。
Can you please help me? I needed to solve this soon. Thank you so much.
更新
我发现这个，并尝试做第3步，但最终打开 WebView 再次。
I found this and tried doing step 3 but it ends up opening the WebView again.
***更新
我终于得到访问令牌，通过调用 onActivityResult（），但获取数据只会在我关闭应用程序后再次显示，这里是我的代码，其中 FACEBOOK_AUTH_RESULT_CODE 值我将其更改为32665.
I finally get the access token, by calling onActivityResult() but the get data will only show after I close the app and open it again here is my code where FACEBOOK_AUTH_RESULT_CODE value I changed it to 32665.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == Constants.FACEBOOK_AUTH_RESULT_CODE) {
facebook.authorizeCallback(requestCode, resultCode, data);
} else {
Log.e(TAG, "onActivityResult Error : Authentication Error");
}
}
推荐答案
毕业：
compile 'com.facebook.android:facebook-android-sdk:[4,5)'
strings.xml
strings.xml
<string name="facebook_app_id">YOUR_APP_ID</string>
AndroidManifest.xml
添加应用程序标签：
AndroidManifest.xml Add inside of 'application' tag:
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id" />
将此创建为初始化FacebookSDK：
Create this to init FacebookSDK:
public class MainApp extends Application {
@Override
public void onCreate() {
super.onCreate();
FacebookSdk.sdkInitialize(getApplicationContext());
}
}
将其添加到AndroidManifest.xml到应用程序标签作为名称：
Add it to AndroidManifest.xml to 'application' tag as the name:
<application
android:name=".MainApp"
在您的活动布局中，添加Facebook登录按钮：
In your activity layout add Facebook Login Button:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.app.FacebookLoginActivity">
<com.facebook.login.widget.LoginButton
android:id="@+id/login_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp"
android:layout_marginBottom="30dp" />
</RelativeLayout>
您的FacebookLoginActivity：您可以在这里获得您的Facebook令牌。
Your FacebookLoginActivity: And Here you can get now your Facebook Token.
public class FacebookLoginActivity extends AppCompatActivity{
private CallbackManager callbackManager;
private LoginButton loginButton;
private String FB_TOKEN;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signin);
callbackManager = CallbackManager.Factory.create();
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile", "user_friends", "email", "user_birthday");
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
/**
* HERE YOU CAN GET YOUR FACEBOOK TOKEN!!!!
**/
FB_TOKEN=loginResult.getAccessToken().getToken();
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException exception) {
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
}
如果您需要使用自定义Facebook按钮：
If you need to use Custom Facebook Button:
public class FacebookLoginActivity extends AppCompatActivity{
private CallbackManager callbackManager;
private Button loginButton;
private String FB_TOKEN;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signin);
callbackManager = CallbackManager.Factory.create();
loginButton = (Button) findViewById(R.id.login_button);
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
/**
* HERE YOU CAN GET YOUR FACEBOOK TOKEN!!!!
**/
FB_TOKEN=loginResult.getAccessToken().getToken();
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException exception) {
Log.e("onError", exception.getMessage());
}
});
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
LoginManager.getInstance().logInWithReadPermissions(FacebookLoginActivity.this, Arrays.asList("public_profile", "user_friends", "email"));
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
}
