Question

这是我的代码：

import serial
import time
import socket
ip = str('url')
port = int(6090)
err = 0
try:
    mySocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    mySocket.connect((ip, port))
    while 1:
        arduino = serial.Serial('/dev/ttyACM0', 9600)
        sensorValue = arduino.readline()
        mySocket.sendall(sensorValue)
except socket.error, msg:
    mySocket.close()
    print 'socket error', msg
mySocket.close

运行此程序后，我收到此消息“套接字错误[Errno -3]名称解析暂时失败”。有人可以帮我解决这个问题吗？

根本问题是import ctypes libc = ctypes.cdll.LoadLibrary('libc.so.6') res_init = libc.__res_init res_init()只能在python启动时读取。要强制刷新解析表，可以运行它（在linux上）：

import React from 'react';

var Albums = React.createClass({
  render() {
    return (
      <ul id="frames_list">
        {this.props.frames.map(function(frames){
          return (
            <li key={frames.frameId}>
              <Link to="/frames" >{frames.frameName}</Link>
            </li>
          )
        }.bind(this))}
      </ul>
    )
  }
});

module.exports = Albums;

我收到一个错误：套接字错误[Errno -3]名称解析暂时失败
