Question

我需要检查一套内联网网站。我试图使用以下法典。 (通过在互联网上的随机搜索而查阅这一法典)。我将这种方法称为我的行动类别。但大多数进入例外部分的地点。尽管我能够从我的浏览器上开放这些场所,但我还是获得了《议定书》的例外和<代码>。

参考守则:

public boolean isLive(String link) {  
  HttpURLConnection urlConnection = null;  
  try {  
    URL url = new URL(link);  
    urlConnection = (HttpURLConnection) url.openConnection();  
    urlConnection.setRequestMethod("HEAD");  
    urlConnection.setConnectTimeout(5000); /* timeout after 5s if can t connect */  
    urlConnection.setReadTimeout(5000); /* timeout after 5s if the page is too slow */  
    urlConnection.connect();  
    String redirectLink = urlConnection.getHeaderField("Location");  
    if (redirectLink != null && !link.equals(redirectLink)) {  
      return isLive(redirectLink);  
    } else {  
      return urlConnection.getResponseCode() == HttpURLConnection.HTTP_OK;  
    }  
  } catch (Exception e) {  
    return false;  
  } finally {  
    if (urlConnection != null) {  
      urlConnection.disconnect();  
    }  
  }  
}

Answer 1

I think No Problem with the code. You have a connection timeout of 5 seconds

urlConnection.setConnectTimeout(5000)

Any query that takes more than 5 seconds will be considered a dead link.Your Browser have much longer timeout than your code so you are able to browse those sites in the browser

如果你重新获得礼宾例外和未知的东道国例外,我们就需要更多了解才能提供帮助。您的机器是否配置成代理? 您是否有东道方定义,由您的集装箱用户共享?

此外,还考虑使用HttpClient等内容来总结这方面的情况,而不是以人工方式进行;工作太多。
