urllib2 超时 [英] urllib2 timeout

问题描述

我正在为我的代码使用 urllib2 库，我使用了很多 (urlopen) loadurl

i'm using urllib2 library for my code, i'm using a lot of (urlopen) loadurl

我的网络出现问题，当我浏览网站时，有时我的浏览器卡在连接"到某个网站上，有时我的浏览器返回超时

i have a problem on my network, when i'm browsing sites, sometimes my browser gets stuck on "Connecting" to a certain website and sometimes my browser returns a timeout

我的问题是，如果我在我的代码上使用 urllib2，它会在尝试连接到某个网站的时间过长时超时，否则代码会卡在该行上.

My question is if i use urllib2 on my code it can timeout when trying to connect for too long to a certain website or the code will get stuck on that line.

我知道 urllib2 可以处理超时而无需在代码中指定它，但它可以应用于这种情况?

i know that urllib2 can handle timeouts without specifying it on code but it can apply for this kind of situation ?

感谢您的时间

def checker(self)
 try:
   html = self.loadurl("MY URL HERE")
   if self.ip_ != html:
(...)
 except Exeption, error:
   html = "bad"

推荐答案

根据我的小调查，urllib2.urlopen() 函数是在 python 2.6 中添加的

from my small research, the urllib2.urlopen() function is added in python 2.6

所以，超时问题应该通过向urllib2.urlopen函数发送自定义超时来解决.代码应该是这样的；

so, the timeout problem should be resolved by sending custom timeout to the urllib2.urlopen function. the code should look like this ;

response = urllib2.urlopen("---在此处插入网址---", None, your-timeout-value)

your-timeout-value 参数是一个可选参数，它以秒为单位定义超时.

the your-timeout-value parameter is an optional parameter which defines the timeout in seconds.

根据您的评论，我知道您不需要等待太长时间的代码，那么您应该拥有以下代码以免卡住；

EDIT : According to your comment, I got that you don't need the code for waiting too long then you should have the following code to not get stuck;

import socket
import urllib2

socket.setdefaulttimeout(10)

10 可以根据与连接速度相关的数学公式进行更改网站加载时间.

10 can be changed according to a math formula related to the connection speed & website loading time.
