问题描述
有没有人有适用于 Android 的 twitter 的 OAuth 身份验证的工作示例?我曾尝试同时使用 Twitter4J 和 SignPost，但出现非常奇怪的错误，说 twitter.com 是未知主机.我已经理解 SignPost 库存在问题(Google Android 下)和Android 和根据项目的主页，CommonsHttpOAuth* 类应该可以工作.
Does anyone have a working example of OAuth authentication for twitter with Android? I have tried to use both Twitter4J and SignPost, but I get very strange errors, saying twitter.com is an unknown host. I have understod that there is a problem (under Google Android) with the SignPost library and Android and according to the project's home-page, the CommonsHttpOAuth* classes shall work.
这是我的路标:
private void getReqTokenAndAuthenticateUsingSignPost() {
String callbackUrl = "twitter-test:///";
CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY,
CONSUMER_SECRET);
CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
"http://twitter.com/oauth/request_token", "http://twitter.com/oauth/access_token",
"http://twitter.com/oauth/authorize");
String tokenStr = consumer.getToken();
String tokenSecretStr = consumer.getTokenSecret();
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
Editor edit = preferences.edit();
edit.putString(REQ_TOKEN, tokenStr);
edit.putString(REQ_TOKEN_SECRET, tokenSecretStr);
try {
String authUrl = provider.retrieveRequestToken(consumer, callbackUrl);
Uri authenticationUri = Uri.parse(authUrl);
startActivity(new Intent(Intent.ACTION_VIEW, authenticationUri));
} catch (OAuthMessageSignerException e) {
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
e.printStackTrace();
} catch (OAuthCommunicationException e) {
e.printStackTrace();
}
}
这是我的 Twitter4J 代码:
and here is my code for Twitter4J:
private void getReqTokenAndAuthenticateUsingTwitter4J() {
String callbackUrl = "twitter-test:///";
try {
// Prepare a request token, based on consumer key and consumer
// secret
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setOAuthConsumerKey(CONSUMER_KEY);
builder.setOAuthConsumerSecret(CONSUMER_SECRET);
Configuration cfg = builder.build();
Twitter t = new TwitterFactory(cfg).getInstance();
RequestToken requestToken = t.getOAuthRequestToken(callbackUrl);
String tokenStr = requestToken.getToken();
String tokenSecretStr = requestToken.getTokenSecret();
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
Editor edit = preferences.edit();
edit.putString(REQ_TOKEN, tokenStr);
edit.putString(REQ_TOKEN_SECRET, tokenSecretStr);
if (edit.commit()) {
// Launch the browser for authentication in twitter's web-gui
Uri authenticationUri = Uri.parse(requestToken.getAuthenticationURL());
startActivity(new Intent(Intent.ACTION_VIEW, authenticationUri));
}
} catch (TwitterException e) {
e.printStackTrace();
}
}
是的，我有一个具有 Internet 许可的清单和一个用于回调 url 的意图过滤器.这是运行 SignPost 代码时 logcat 的输出:
and yes, I have a manifest with Internet permission and an intent filter for the callback-url. Here is the output from logcat when running the SignPost code:

有人解决了吗?我被困在这里.我可以让代码作为 Java SE 程序运行，但它在 android 上失败...
Have anybody resolved this? I'm stuck here. I can get the code to run as a Java SE program, but it fails on android...

推荐答案
检查并确认两件事 -
Check and Confirm Two Things -
1-在您在 twitter 网站上创建的您的 twitter 应用程序中提供回调 URL(转到您的应用程序-> 设置-> 回调 URL) 点击这里
2-转到电话设置，然后单击日期和时间"并选择自动"(请确保您的设备时区和时间、日期都正确)如果您的时间、日期和时区不正确，你不能发推文.
2-Go to Phone settings then click 'Date and Time' and select 'Automatic' (Please make sure your device Time Zone and Time,Date all are correct) If your time,Date and Time Zone are not correct then you can not tweet.
