HttpUrlConnection.disconnect会关闭InputStream吗？

Question

在调用disconnect()之后，InputStream仍然可用吗？

我想为HTTP请求创建一个助手类，该类将返回InputStream，但会关闭连接。有可能吗？

例如：

public InputStream Get(String url) {
    URL u = new URL(url);
    HttpUrlConnection con = (HttpUrlConnection) url.openConnection();
    InputStream in = null;
    try {
        in = con.getInputStream();
    } finally {
        con.disconnect();
    }

    return in;
}

Answer 1

不可能的。inputstream只是通向服务器的管道，它不包含任何数据。你可以这样做：

public byte[] Get(String url) {
URL u = new URL(url);
byte [] data = null
HttpUrlConnection con = (HttpUrlConnection) url.openConnection();
InputStream in = null;
try {
    in = con.getInputStream();
    data = readDataFromStream(in);
} finally {
    con.disconnect();
}

return data;

}

Answer 2

在断开con之前，请确保您已经阅读了InputStream！
