【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。
Twitter API 最近更新了，所以我无法发送回调 URL。
现在设置页面也发生了变化，没有选择基于 Web 的应用程序或桌面应用程序的选项。
如果我在这一行发送回调：
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 重定向到 Twitter 登录页面中发送 Null，但在成功授权后它不会返回到我的应用程序。
显示 Pin 号码后，我想重定向回我的应用程序。
注意：Twitter 已更新其 API，因此帖子中可用的旧代码无法正常工作。
我尝试了所有以下链接
Link 1, Link 2, Link 3, Link4 , Link5 , Link 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();
}
}
/**

* 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" />

401 错误可能是由多种原因引起的。特别要检查您的 API 密钥是否正确（没有多余的空格或缺少字符），并检查您设备上的日期/时间和时区是否正确。

@Dave 你在你的应用程序中使用过 Twitter 吗？
