在Java中对http请求使用writeUTF和readUTF

这是一种尝试对指定网页进行爬网的Java方法。我使用writeUTF和readUTF与服务器进行套接字通信。

static void get_html(String host, String page, int port) throws IOException {
        Socket sock = new Socket(host, port);
        String msg = MessageFormat.format("GET {0} HTTP/1.1\r\nHost: {1}\r\n\r\n", page, host);

        DataOutputStream outToServer = new DataOutputStream(sock.getOutputStream());
        DataInputStream inFromServer = new DataInputStream(sock.getInputStream());

        InputStream stream = new ByteArrayInputStream(msg.getBytes(StandardCharsets.UTF_8));
        BufferedReader buf = new BufferedReader(new InputStreamReader(stream));
        String outMsg;

        while ((outMsg = buf.readLine()) != null) {
            System.out.println("Sending message: " + outMsg);
            outToServer.writeUTF(outMsg);

            String inMsg;
            try {
                inMsg = inFromServer.readUTF();
            } catch (EOFException eof) {
                break;
            }
            System.out.println(inMsg);
        }
        sock.close();
    }

我这样写的原因是为了模仿 c 代码,其中有一个while循环 send() 从缓冲区进行所有传递,以及另一个while循环 recv() 从缓冲区直到它到达“null”。当执行我的代码时,它只是挂在那里,我怀疑这是由于在我发送完所有消息之前调用了readUTF。如果是这种情况,有没有办法解决?
