Question

我想在java中获取一个代理，在socket中获取服务器的响应并更改html代码，然后将客户端作为套接字连接中的响应传递。
现在我的程序可以从客户端获取请求，并且可以从服务器获得响应并将其正确地传递给客户端但是我无法更改html代码。这是我的代码：

Thread thread = new Thread() {
    public void run() {
        int bytesRead;
        try {
            while ((bytesRead = streamFromClient.read(request)) != -1) {
                streamToServer.write(request, 0, bytesRead);
                streamToServer.flush();
            }
            Logging incomingLog = new Logging("Incoming", tmpClient.toString());
            incomingLog.doLog();
        } catch (IOException e) {
            Logging IOExceptionLog = new Logging("Error", "Proxy cannot read client request - Client: "
                    + tmpClient.toString() + ".\nException : " + e.getMessage() + "\n");
            try {
                IOExceptionLog.doLog();
            } catch (IOException e1) {
                //Ignore me!!!
            }
        }

        // the client closed the connection to us, so close our
        // connection to the server.
        try {
            streamToServer.close();
        } catch (IOException e) {
            Logging log = new Logging("Error", "Proxy could not close connection to server.");
            try {
                log.doLog();
            } catch (IOException e1) {
                //Ignore me!!!
            }
        }
    }
};

thread.start();// Start the client-to-server request thread running;

// Read the server's responses
// and pass them back to the client;
int bytesRead;
InputStream tempStreamFromServer = streamFromServer;

/*ConvertStream convertor = new ConvertStream();
  String htmlCode = convertor.getStringFromInputStream(tempStreamFromServer);*/

try {
    while ((bytesRead = streamFromServer.read(response)) != -1) {
        streamToClient.write(response, 0, bytesRead);
        streamToClient.flush();
    }

    Logging incomingLog = new Logging("OutComing", tmpClient.toString());
    incomingLog.doLog();
} catch (IOException e) {
    Logging IOExceptionLog = new Logging("Error", "Proxy cannot send client response - Client: "
            + tmpClient.toString() + ".\nException : " + e.getMessage() + "\n");
    IOExceptionLog.doLog();
}

// The server closed its connection to us, so we close our
// connection to our client.
streamToClient.close();

任何人都可以帮助我吗？

我终于可以找到问题了。

问题在于threads.I在我的程序中有两个线程：

1.Thread A：得到服务器的响应。

2.Thread B：更改html代码并将其传递给客户端。

现在的问题是，当线程A有一个循环从服务器接受响应并将它们传递给线程B，而线程B也有一个等待来自线程A的响应的循环。

现在，当线程B想要更改html代码时，此操作会给线程B带来延迟，线程A不会等待线程B。

我在对线程B传递一个响应并在处理html代码之后从线程B通知线程A时，用等待线程A解决了这个问题。
