Question

我试图破解一种在两台计算机之间发送邮件的方法。以下代码创建用于接收消息的线程。

import socket               # Import socket module
import threading
import traceback
def recv_one_message(sock):
    lengthbuf = recvall(sock, 4)
    length, = struct.unpack('!I', lengthbuf)
    return recvall(sock, length)

def recvall(sock, count):
    buf = b''
    while count:
        newbuf = sock.recv(count)
        if not newbuf: return None
        buf += newbuf
        count -= len(newbuf)
    return buf

host="ec2-35-160-33-3.us-west-2.compute.amazonaws.com"
kill_threads=False

def receive_thread():
    while not kill_threads:
        try:
            # Create a socket object
            soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)        
            soc.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
            port = 8502                # Reserve a port for your service.
            soc.bind((host, port))     # Bind to the port
            print("port bound")
            soc.settimeout(10)
            soc.listen(50000000)       # Now wait for client connection.
            conn, addr = soc.accept()  # Establish connection with client.
            soc.settimeout(None)
            print ("Got connection from",addr)
            while not kill_threads:
                msg_binary=recv_one_message(soc)
                msg=str(msg_binary, "utf-8")
                print(msg)
        except Exception:
            traceback.print_exc()
        try:
            conn.close()
            soc.close()
        except Exception:
            traceback.print_exc()

t2 = threading.Thread(target=receive_thread)
t2.daemon=True
t2.start()

我收到以下错误：

Traceback (most recent call last):
  File "<ipython-input-3-eaef71a53845>", line 59, in receive_thread
    msg_binary=recv_one_message(soc)
  File "<ipython-input-3-eaef71a53845>", line 7, in recv_one_message
    lengthbuf = recvall(sock, 4)
  File "<ipython-input-3-eaef71a53845>", line 14, in recvall
    newbuf = sock.recv(count)
OSError: [Errno 107] Transport endpoint is not connected

这是我的Scala发件人，它试图连接到Python部分并发送＆＃34; hello world＆＃34;一秒一次。

import java.io._
import java.net._
import java.nio.charset.Charset

val host = "ec2-35-160-33-3.us-west-2.compute.amazonaws.com"
new Thread {
  override def run() {
    while (true) {
      try {
        print("trying to establish connection")
        val soc = new Socket(host, 8502)
        val dout = new DataOutputStream(soc.getOutputStream())
        print("connection established")
        val serializedMessage = "hello world"
        val serializedMessageBytes = (serializedMessage).getBytes(Charset.forName("UTF-8"))
        while (true) {
          dout.write(serializedMessageBytes.length)
          dout.write(serializedMessageBytes)
          dout.flush()
          Thread.sleep(1000)
        }
      } catch {
        case e => e.printStackTrace()
      }
    }
  }
}.start()

        conn, addr = soc.accept()  # Establish connection with client.
        ...
            msg_binary=recv_one_message(soc)

您需要接收从accept（conn）获得的连接套接字上的数据，而不是在侦听器套接字（soc）上接收数据。

Python套接字：[Errno 107]传输端点未连接
