ValueError：使用套接字时要解压的值太多

Question

import socket
import time
HOST = "192.168.x.x"
PORT = 5454
data = "Hello"
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(HOST,PORT)
while  True:
   s.sendto(data(HOST,PORT))
   print "send" + data
   time.sleep(1)

我收到这样的错误：

Traceback (most recent call last):

我正在尝试在 Google App Engine 中使用套接字。这是我放在我的main.py. 我如何摆脱这个错误？

Answer 1

从17.2. socket — 低级网络接口：

套接字地址表示如下： ...一对（主机，端口）用于 AF_INET 地址系列，其中主机是一个字符串，表示互联网域符号中的主机名，如“daring.cwi.nl”或 IPv4 地址像'100.50.200.5'，端口是一个整数。

和

插座。连接（地址）

连接到地址处的远程套接字。（地址的格式取决于地址族——见上文。）

Note

This method has historically accepted a pair of parameters for AF_INET addresses instead of only a tuple. This was never intentional

并且在 Python 2.0 及更高版本中不再可用。

这意味着你应该改变

s.connect(HOST,PORT)

和

s.connect((HOST,PORT))

同样下面的变化

   s.sendto(data(HOST,PORT))

和

   s.sendto(data, (HOST,PORT))

附注：在使用s.sendto()的插座应不相连（或降s.connect()或使用s.send()或s.sendall()）：

socket.sendto(string, address) socket.sendto(string, flags, address)

向套接字发送数据。套接字不应连接到远程套接字，因为目标套接字是由地址指定的。可选的 flags 参数与上面的 recv() 具有相同的含义。返回发送的字节数。（地址的格式取决于地址族——见上文。）
