Question

我正在读取一个包含HTTP连接的InputStream，如下所示：

       InputStream in = s3Object.getObjectContent();
       ByteArrayOutputStream out = new ByteArrayOutputStream(8192);
        byte[] tmp = new byte[8192];
        int r;
        while (true) {
            r = in.read(tmp);
            if(r <= 0) break;
            out.write(tmp,0,r);
        }
        in.close();

并获得“Socket is closed”异常，有线日志显示以下内容：

Apache HttpClient 4.1.1.510.540和 Apache HttpCore 4.1.521.51

这是否意味着在我完成阅读之前远程端已关闭套接字？或者我的HttpClient库或我正在使用的某个库正在关闭连接，然后才能读取所有数据？

Answer 1

您的应用程序看起来很快就会关闭HttpClient连接池。您在问题中显示的代码中没有发生这种情况。该代码看起来像“无辜的受害者”。

这是我使用的HttpClient版本的问题吗？

可能不是。

或者我环境中的某些事情改变了行为？

呃......可能是。特别是如果“我的环境”是说你的程序的其他部分的一种模糊的方式。

Answer 2

“套接字已关闭”异常

您的结束关闭了套接字。如果对等方已经关闭了他的结束，那么在阅读时会有一些EOS，或者在写入时会出现IOException：'connection reset'。

插座是从我的端部还是从另一端封闭的
