Question

如何在Java服务器应用程序中访问HTTP PUT消息（JSON格式）？ HTTP PUT是从Python客户端发送的。

到目前为止

Python客户端：

    import http.client 
    import urllib

    values = {'s':'basic','submit':'search'}
    data = urllib.parse.urlencode(values)


    headers = headers['Content-length']=str(len(bytes(data, 'utf-8')))
    connection =  http.client.HTTPConnection('localhost',8080)
    connection.request("PUT", "/file", body=data.encode("utf-8"))

当PUT到达Java服务器时 - 如何获取消息（来自Python的数据）？

到目前为止，这就是我在Java中所拥有的：

import java.io.*;
import java.net.*;

class JavaServer {

    public static void main(String args[]) throws Exception {

        String fromclient;

        ServerSocket Server = new ServerSocket (8080);

        System.out.println("TCPServer Waiting for client on port 8080");

        Socket connected = Server.accept();
        System.out.println( " THE CLIENT"+" "+ connected.getInetAddress() +":"+connected.getPort()+" IS CONNECTED ");

        BufferedReader inFromClient = new BufferedReader(new InputStreamReader (connected.getInputStream()));

        fromclient = inFromClient.readLine();
        System.out.println( "RECIEVED:" + fromclient );

    }
}

Answer 1

您需要迭代“inFromClient”

类似于：

    while((fromclient = inFromClient.readLine()) != null){
        System.out.println( "RECIEVED:" + fromclient );
    }
    inFromClient.close();

Answer 2

谢谢。这确实有效。我也刚刚发现了这个：

StringBuilder buffer = new StringBuilder();
String line;
while ((line = inFromClient.readLine()) != null) {
buffer.append(line);
}

System.out.println("buffer.toString = " + buffer.toString());

然而，这也有效，json消息似乎有很多额外的字符，似乎混淆了。我是JSON的新手。也许这是正常的，或者我需要双引号。我实际上发送时间和IP地址和值。数字是否需要使用JSON进行特殊格式化？
