Apache-HttpComponents:套接字关闭错误

Question

我正在编写一个Java程序，它使用Apache-HttpComponents加载页面并将其HTML打印到控制台；然而，在抛出以下错误之前，该程序仅打印部分HTML：Exception in thread "main" java.net.SocketException: socket closed.每次我运行该程序时，在异常之前显示的HTML部分完全相同，并且错误发生在这个使用谷歌、雅虎和Craigslist的简化示例中：

String USERAGENT = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22";
DefaultHttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet("http://www.craigslist.org");
get.setHeader(HTTP.USER_AGENT,USERAGENT);
HttpResponse page = client.execute(get);
get.releaseConnection();
InputStream stream = page.getEntity().getContent();
try{
    BufferedReader br = new BufferedReader(new InputStreamReader(stream));
    String line = "";
    while ((line = br.readLine()) != null){
        System.out.println(line);
    }
}
finally{
    EntityUtils.consume(page.getEntity());
}

Answer 1

我发现只有在我读完HTML后才能调用get.releaseConnection();。在EntityUtils.consume(page.getEntity());修复上述代码后立即调用它。
