android - HttpUrlConnection.disconnect 会关闭 InputStream 吗？

Question

调用 disconnect() 后 InputStream 是否仍然可用？

我想为将返回 InputStream 但关闭连接的 HTTP 请求创建一个帮助程序类。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

在断开连接之前，请确保您已阅读 InputStream！

Answer 2

不可能。输入流只是到服务器的管道，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;
