综观urllib2的来源,它看起来像这样做将是子类化HTTPRedirectHandler,然后用比如build_opener覆盖默认化HTTPRedirectHandler,最简单的方法,但是这似乎是很多的(相对复杂)工作,做什么似乎像它应该是很简单。
Answer 1:
下面是请求方式:
import requests
r = requests.get('http://github.com', allow_redirects=False)
print(r.status_code, r.headers['Location'])
Answer 2:
深入Python有处理一个很好用章重定向的urllib2。 另一种解决方案是httplib的 。
>>> import httplib
>>> conn = httplib.HTTPConnection("www.bogosoft.com")
>>> conn.request("GET", "")
>>> r1 = conn.getresponse()
>>> print r1.status, r1.reason
301 Moved Permanently
>>> print r1.getheader('Location')
http://www.bogosoft.com/new/location
Answer 3:
这是一个不会跟随重定向一个urllib2的处理程序:
class NoRedirectHandler(urllib2.HTTPRedirectHandler):
def http_error_302(self, req, fp, code, msg, headers):
infourl = urllib.addinfourl(fp, headers, req.get_full_url())
infourl.status = code
infourl.code = code
return infourl
http_error_300 = http_error_302
http_error_301 = http_error_302
http_error_303 = http_error_302
http_error_307 = http_error_302
opener = urllib2.build_opener(NoRedirectHandler())
urllib2.install_opener(opener)
Answer 4:
我想这将有助于
from httplib2 import Http
def get_html(uri,num_redirections=0): # put it as 0 for not to follow redirects
conn = Http()
return conn.request(uri,redirections=num_redirections)
Answer 5:
该redirections
在关键字httplib2
请求方法是一种红色的鲱鱼。 而不是返回它将会引发的第一个请求RedirectLimit
如果它收到一个重定向状态码异常事件。 要返回您需要设置inital响应follow_redirects
到False
上Http
对象:
import httplib2
h = httplib2.Http()
h.follow_redirects = False
(response, body) = h.request("http://example.com")
Answer 6:
我第二OLT的指针, 深入Python 。 下面是使用的urllib2重定向处理程序的实现,比它更多的工作应该是什么? 也许,耸肩。
import sys
import urllib2
class RedirectHandler(urllib2.HTTPRedirectHandler):
def http_error_301(self, req, fp, code, msg, headers):
result = urllib2.HTTPRedirectHandler.http_error_301(
self, req, fp, code, msg, headers)
result.status = code
raise Exception("Permanent Redirect: %s" % 301)
def http_error_302(self, req, fp, code, msg, headers):
result = urllib2.HTTPRedirectHandler.http_error_302(
self, req, fp, code, msg, headers)
result.status = code
raise Exception("Temporary Redirect: %s" % 302)
def main(script_name, url):
opener = urllib2.build_opener(RedirectHandler)
urllib2.install_opener(opener)
print urllib2.urlopen(url).read()
if __name__ == "__main__":
main(*sys.argv)
Answer 7:
然而,最短的路
class NoRedirect(urllib2.HTTPRedirectHandler):
def redirect_request(self, req, fp, code, msg, hdrs, newurl):
pass
noredir_opener = urllib2.build_opener(NoRedirect())
