标签: python-3.x url web urllib

我试图通过urllib.request.urlopen获取ulr状态,在某些情况下,它会返回urllib.error.URLError: HTTP Error 403: Forbidden我是否可以成功从浏览器中打开此网址。 是否有可能用urllib或更好的方法来解决这个问题,以便使用其他一些lib?

def urllib_status(url):
    REQUEST_TIMEOUT = 10

    if 'http' not in url:
        url = 'http://' + url

    try:
        response = urllib.request.urlopen(url, timeout=REQUEST_TIMEOUT)
        return response.status
    except urllib.error.URLError as e:
        print('url:'+url)
        print('urllib.error.URLError:', e)
        return -1
    except ssl.SSLError as e:
        print('url:'+url)
        print('ssl.SSLError:', e)
        return -1
    except socket.error as e:
        print('url:'+url)
        print("socket.error: ", e)
        return -1

问题可能是由于网站不接受非浏览器请求。您可以通过覆盖请求中的User-Agent标头来解决此问题(默认为Python-urllib/3.X)。

来自Python docs

 import urllib.request
 opener = urllib.request.build_opener()
 opener.addheaders = [('User-agent', 'Mozilla/5.0')]
 opener.open('http://www.example.com/')

或者,如果您正在使用requests(Python用户中事实上的标准HTTP库)

import requests
requests.get('http://www.example.com/', headers={'User-agent': 'Mozilla/5.0'})

使用requests

进行模拟
def url_status(url):
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.0; WOW64; rv:24.0)'
                             ' Gecko/20100101 Firefox/24.0'}
    REQUEST_TIMEOUT = 10

    if 'http' not in url:
        url = 'http://' + url
    try:
        response = requests.get(url, headers=headers, timeout=REQUEST_TIMEOUT)
        if(response.status_code != 200):
            print(url)
            print('status',response.status_code)
        return response.status_code
    except Exception as e:
        print(url)
        print('Error',e)
        return -1
