如何使用 Twitter 4J 更新推文?
我正在使用 Twitter4J (2.1.0) 尝试更新推文。我无法弄清楚我的代码有什么问题。
我的问题特别是:
(a) 并非所有推文都成功发布。我经常收到-1 的错误代码。根据 Google 群组帖子...
当内部 http 组件无法连接到时,您会得到代码 -1 或从 API 读取。当 API 运行时,您也可能会得到代码 -1 由于 DNS 相关问题,无法从 JVM 访问。
奇怪的是,我似乎几乎每隔一秒就会收到这个帖子。为了解决这个问题,每当我收到 -1 错误代码时,我都会尝试再次更新。虽然我意识到这不是一个很好的解决方案。这修复了 95% 的问题
(b) 每当新推文与任何旧推文匹配时,我都会收到重复错误(错误代码 403)
即使出现错误代码 403重复内容现已过时(例如,发布“Hello There”,发布各种状态更新,然后再次发布“Hello There”,抛出 TwitterException,错误代码为 403)
我当前的代码...
我的代码位于 AsyncTask 中,而 AsyncTask 又位于服务(而不是活动)中。我已经包含了 Asynctask 代码和下面的另一种方法......
class SendTwitAsyncTask extends AsyncTask<String, Void, Void> {
@Override
protected Void doInBackground(String... params) {
String tokenTwit = params[0];
String tokenSecretTwit = params[1];
String strMessageBody = params[2];
AccessToken aToken = new AccessToken(tokenTwit, tokenSecretTwit);
// initialize Twitter4J
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
twitter.setOAuthAccessToken(aToken);
// create a tweet
// strMessageBody varies
String tweet = strMessageBody;
boolean bool = twitter.isOAuthEnabled();
if (twitter.isOAuthEnabled()) {
GeoLocation geolocation = new GeoLocation(-33.91, 151.25);
try {
twitter.updateStatus(tweet, geolocation);
showNotification("Twitter One" , TWIT_SUCCESS);
} catch (TwitterException te) {
if (te.getStatusCode() == -1) {
//try again
try {
twitter.updateStatus(tweet, geolocation);
showNotification("Twitter Two ", TWIT_SUCCESS);
}
catch (TwitterException tetwo) {
describeTwitException(tetwo.getStatusCode());
}
} //end if
//else exception other than -1
else {
describeTwitException(te.getStatusCode());
} //end else
}// end outer catch
} //end if
else {
showNotification("Unable to authenticate" , TWIT_FAIL);
}//
return null;
}
} //end class SendTwitAsyncTask
public void describeTwitException(int twitExceptionCode) {
switch (twitExceptionCode) {
case (-1):
showNotification("Twitter (unable to connect)", TWIT_FAIL);
break;
case(403):
showNotification("Twitter (duplicate tweet)", TWIT_FAIL);
break;
default:
showNotification("Twitter", TWIT_FAIL);
} //end switch
} //end describeTwitException method
I am using Twitter4J (2.1.0) to try to update tweets. I can't figure out what is wrong with my code.
In particular my problems are:
(a) Not all tweets post successfully. I often get the error code of -1. According to a google group post...
You get code -1 when the internal http component fails to connect to
or read from the API. You may also get code -1 when the API is
unreachable from the JVM due to the DNS related issues.
Strangely I seemed to be getting this pretty much every second post. To deal with this whenever I received the -1 error code I would try to update again. While I realise this is not a very good solution. this fixed the probem 95% of the time
(b) I get a duplication errors (error code 403) whenever the new tweet matches any old tweet
Error code 403 occurs even if the duplicate is now outdated (eg. post "Hello there", post a variety of status updates, then post "Hello there" again throws a TwitterException with error code 403)
My current code...
My code is in an AsyncTask which is in turn in a Service (rather than activity). I have included the Asynctask code and another method below....
class SendTwitAsyncTask extends AsyncTask<String, Void, Void> {
@Override
protected Void doInBackground(String... params) {
String tokenTwit = params[0];
String tokenSecretTwit = params[1];
String strMessageBody = params[2];
AccessToken aToken = new AccessToken(tokenTwit, tokenSecretTwit);
// initialize Twitter4J
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
twitter.setOAuthAccessToken(aToken);
// create a tweet
// strMessageBody varies
String tweet = strMessageBody;
boolean bool = twitter.isOAuthEnabled();
if (twitter.isOAuthEnabled()) {
GeoLocation geolocation = new GeoLocation(-33.91, 151.25);
try {
twitter.updateStatus(tweet, geolocation);
showNotification("Twitter One" , TWIT_SUCCESS);
} catch (TwitterException te) {
if (te.getStatusCode() == -1) {
//try again
try {
twitter.updateStatus(tweet, geolocation);
showNotification("Twitter Two ", TWIT_SUCCESS);
}
catch (TwitterException tetwo) {
describeTwitException(tetwo.getStatusCode());
}
} //end if
//else exception other than -1
else {
describeTwitException(te.getStatusCode());
} //end else
}// end outer catch
} //end if
else {
showNotification("Unable to authenticate" , TWIT_FAIL);
}//
return null;
}
} //end class SendTwitAsyncTask
public void describeTwitException(int twitExceptionCode) {
switch (twitExceptionCode) {
case (-1):
showNotification("Twitter (unable to connect)", TWIT_FAIL);
break;
case(403):
showNotification("Twitter (duplicate tweet)", TWIT_FAIL);
break;
default:
showNotification("Twitter", TWIT_FAIL);
} //end switch
} //end describeTwitException method

Twitter API 将拒绝任何与您已发布的推文相匹配的推文。我认为旧推文永远不会“过期”。
The twitter API will reject any tweet that matches a tweet that you've already made. I don't think the old tweet ever 'expires.'
