问题描述
我使用Twitter4J库OAuth认证,但我得到验证挑战是空例外它打开了微博登录页面之前。
I'm using Twitter4J library for OAuth authentication but I get "Authentication Challenge is Null Exception" even before It opens the Twitter login page.
下面是code。
Twitter twitter = new TwitterFactory().getInstance();
try
{
twitter.setOAuthConsumer(Startup.TWITTER_KEY, Startup.TWITTER_SECRET);
String callbackURL = "twitter-client:///";
RequestToken rToken = twitter.getOAuthRequestToken(callbackURL);
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(rToken.getAuthenticationURL())));
}
catch(IllegalStateException e)
{
// access token is already available, or consumer key/secret is not set.
if(!twitter.getAuthorization().isEnabled()){
System.out.println("OAuth consumer key/secret is not set.");
System.exit(-1);
}
}
catch(Exception e)
{
Toast.makeText(Home.this, "Network Host not responding: "+e.getMessage(),Toast.LENGTH_SHORT).show(); //This exception.
}

推荐答案
我有同样的问题。原来,如果对OAuth的通话时间戳记不正确,服务器返回401状态错误,在Android设备上导致已收到认证挑战为空引发异常。所有这一切都为这个问题有不正确时间和固定时间的设备解决了问题。
I had the same problem. It turned out that if the time stamp on the oAuth call is incorrect, the server returns a 401 status error which on Android devices causes the "Received authentication challenge is null" exception to be thrown. All of the devices that were having this problem had incorrect times, and fixing the times fixed the problem.
也许这就是你的问题呢?
Perhaps this is your issue as well?
