我在我的应用程序中实现了 Twitter,我在回调中遇到问题。
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,没有用于选择基于 Web 的应用程序或桌面应用程序的选项。
如果我在此行中发送回调:
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.
但是如果我发送为 Null 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。
显示密码后,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使用。
我尝试了所有以下链接
链接 1, 链接 2, 链接 3, 链接4 , 链接5 , 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

}
}

@Override

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" />
问题是回调 URl。 我们应该在应用程序设置页面的回调 URL 字段名称中提供一个虚拟回调 URL。
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Redirecting to your Application
的选项有关进一步参考,请查看此 Twitter 链接
你找到问题出在哪里了吗?我有同样的例外,最后我找到了它的来源。就是Twitter的设置页面发生了变化,您不能再选择基于Web的应用程序或桌面应用程序。但这里有一些提示:在您的 Twitter 应用程序的设置中,只需使用像 http://www.dummy.com 这样的虚拟网址填充回调 URL。这将隐式设置您的应用程序具有网络浏览器,然后当您发送自己的回调时,它将替换虚拟浏览器。 我花了很多时间才找到这个,所以我希望这个答案能帮助别人。
将以下
Callback URL
添加到应用程序中将解决问题。它将用户重定向到 Application
启动它以验证用户的 Twitter
帐户_
更新在
Manifest
_
<activity android:name="<YOUR ACTIVITY NAME>"
android:launchMode="singleTask" android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:screenOrientation="portrait">
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<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="x-oauthflow-twitter" android:host="callback" />
</intent-filter>
在你的
TwitterManager
里,你拥有所有的TwitterFactory
和所需的东西_
final public static String CALLBACK_SCHEME = "x-oauthflow-twitter";
final public static String CALLBACK_URL = CALLBACK_SCHEME + "://callback";
public static final String TWITTER_IEXTRA_OAUTH_VERIFIER = "oauth_verifier";
终于可以得到你想要的一切了_ 例如,
getHost
、getScheme
、getEncodedQuery
、getQuery
、getEncodedSchemeSpecificPart
和更多根据您的需要使用通过回调返回的intent
_
@Override
protected void onNewIntent(final Intent intent) {
super.onNewIntent(intent);
new AsyncTask<Void,Void,Void>(){
@Override
protected Void doInBackground(Void... arg0) {
Uri uri = intent.getData();
if (uri != null && uri.toString().startsWith(TwitterManager.TWITTER_CALLBACK_URL)) {
String verifier = uri.getQueryParameter(TwitterManager.TWITTER_IEXTRA_OAUTH_VERIFIER);
Log.e("---ActivityMain-onNewIntent---", "verifier:"+verifier+", uri- getQuery:"+uri.getQuery());
Log.i(ApplicationPockets.TAG, "verifier : "+verifier);
if(verifier != null){
try {
/*
*---Get the AccessToken and do what you like ... :)
*/
AccessToken accessToken = twitter.getOAuthAccessToken(requestToken, verifier);
SharedPreferences.Editor e = context.getSharedPreferences(SF_TWITTER, Context.MODE_PRIVATE).edit();
e.putString(TWITTER_PREF_KEY_TOKEN, accessToken.getToken());
e.putString(TWITTER_PREF_KEY_SECRET, accessToken.getTokenSecret());
e.commit();
//Extra you would like to do...
} catch (TwitterException e) {
e.printStackTrace();
}
}else{
//Logout Twitter.
}
}
return null;
}
}.execute();
}
您的 RequestToken_
try {
RequestToken requestToken = twitter.getOAuthRequestToken(TWITTER_CALLBACK_URL);
//Toast.makeText(activity, "Please authorize this app!", Toast.LENGTH_LONG).show();
activity.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(requestToken.getAuthenticationURL())));
} catch (TwitterException e) {
e.printStackTrace();
}
希望对大家有所帮助_
