Android 中 Twitter 回调问题 [英] Problem in Callback in Twitter in Android
问题描述
我已经在我的应用程序中实现了 Twitter，我在回调中遇到了问题.
I have implemented Twitter in my application , i am facing problem in Callback.
Twitter API 最近已更新，因此我无法发送回调 URL.
Twitter API's has been updated recently so i am unable to send Callback URL.
现在设置页面也发生了变化，没有用于选择基于 Web 的应用程序或桌面应用程序的选项.
Also the Setting Page now change there is No Option for Selecting Web Based application or Desktop Application.
如果我在这条线上发送回调:
If i send Callback in this Line :
authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URL);
它总是返回
oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.
但如果我在此发送 Null 其重定向到 Twitter 登录页面，但在成功授权后，它不会返回到我的应用程序.
but if i send as Null in this its Redirecting to Twitter Login Page,but after successful Authorization it doesn't returns back to my Application.
显示密码后，我想重定向回我的应用程序.
After the Pin number is displayed i want to Redirect back to my Application.
注意:Twitter 更新了他们的 API，因此帖子中可用的旧代码无法使用.
Note : Twitter had updated their API so old Codes available in the Post is not working.
我尝试了以下所有链接
链接 1，链接 2，链接 3，Link4 ,Link5 ,链接 6
我的代码如下:
public class Main extends Activity {
OAuthConsumer consumer;
OAuthProvider provider;
Twitter twitter;
private static String CALLBACK_URL = "twitterapptest://connect";
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
consumer = new DefaultOAuthConsumer(
"XXXXXXXXXXX",
"XXXXXXXXXXXXX");
provider = new DefaultOAuthProvider(
"https://api.twitter.com/oauth/request_token",
"https://api.twitter.com/oauth/access_token",
"https://api.twitter.com/oauth/authorize");
String authUrl = null;
try {
authUrl = provider.retrieveRequestToken(consumer,null);
this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
} catch (OAuthMessageSignerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthCommunicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String pin = null;
try {
pin = br.readLine();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
provider.retrieveAccessToken(consumer, "4947222");
} catch (OAuthMessageSignerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthCommunicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
URL url = null;
try {
url = new URL("http://twitter.com/statuses/mentions.xml");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
HttpURLConnection request = null;
try {
request = (HttpURLConnection) url.openConnection();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
consumer.sign(request);
} catch (OAuthMessageSignerException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (OAuthExpectationFailedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (OAuthCommunicationException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
request.connect();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
System.out.println("Response: " + request.getResponseCode() + " "
+ request.getResponseMessage());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* As soon as the user successfully authorized the app, we are notified
* here. Now we need to get the verifier from the callback URL, retrieve
* token and token_secret and feed them to twitter4j (as well as
* consumer key and secret).
*/
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Uri uri = intent.getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
String verifier = uri
.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
try {
// this will populate token and token_secret in consumer
provider.retrieveAccessToken(consumer,
verifier);
// TODO: you might want to store token and token_secret in you
// app settings!!!!!!!!
AccessToken a = new AccessToken(consumer.getToken(),
consumer.getTokenSecret());
// initialize Twitter4J
twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer("XXXXXXX", "XXXXXXXXXX");
twitter.setOAuthAccessToken(a);
// create a tweet
Date d = new Date(System.currentTimeMillis());
String tweet = "#OAuth working! " + d.toLocaleString();
// send the tweet
twitter.updateStatus(tweet);
} catch (Exception e) {
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
}
}
我的清单:
<?xml version="1.0" encoding="utf-8"?>
<activity android:name=".OAuthForTwitter" android:label="@string/app_name"
android:configChanges="orientation|keyboardHidden" android:launchMode="singleInstance">
<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="twitterapptest" android:host="connect" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.INTERNET" />
推荐答案
问题在于回调 URl.我们应该在应用程序设置页面的回调 URL 的字段名称中提供一个虚拟回调 URL.
The problem is that Callback URl. We should give one Dummy Callback URL in the Field Name of CallBack URL in Application' s Settings Page.
如果我们这样做并在我们的代码中发送回调 URL，成功登录后将有一个名为重定向到您的应用程序
If we do like that and send the Call Back URL in our code, after successful Login there will be a option called Redirecting to your Application
