Python3:urllib.error.HTTPError:HTTP 错误 403:禁止 [英] Python3: urllib.error.HTTPError: HTTP Error 403: Forbidden
问题描述
请帮帮我!
我使用的是 Python3.3 和这段代码:
导入 urllib.request导入系统Open_Page = urllib.request.urlopen(http://wowcircle.com").read().decode().encode('utf-8')
我接受这个:

我了解,我无法访问网站 wowcircle.com.但我只想拿源代码!我相信我可以在没有访问权限的情况下做到这一点,但如何做到?
我建议您相应地设置标题.查看您的浏览器发送的内容(HTTP 标头插件).
一个函数可能如下所示:
def openAsOpera(url):u = urllib.URLopener() # Python 3: urllib.request.URLOpeneru.addheaders = []u.addheader('User-Agent', 'Opera/9.80 (Windows NT 6.1; WOW64; U; de) Presto/2.10.289 Version/12.01')u.addheader('Accept-Language', 'de-DE,de;q=0.9,en;q=0.8')u.addheader('接受', 'text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/webp, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1')f = u.open(url)内容 = f.read()f.close()返回内容
这可以让您解决某些网页上的一些错误,这些错误对客户端的期望高于基本版本.
现在我收到此错误:
回溯(最近一次调用最后一次):文件<pyshell#0>",第 1 行,在 <module> 中s = openAsOpera('http://wowcircle.com/')文件C:....pyw",第 522 行,在 openAsOperaf = u.open(url)文件C:\Python27\lib\urllib.py",第 208 行,打开返回 getattr(self, name)(url)文件C:\Python27\lib\urllib.py",第 359 行,在 open_http返回 self.http_error(url, fp, errcode, errmsg, headers)文件C:\Python27\lib\urllib.py",第 376 行,在 http_error 中返回 self.http_error_default(url, fp, errcode, errmsg, headers)文件C:\Python27\lib\urllib.py",第 381 行,在 http_error_default 中引发 IOError, ('http error', errcode, errmsg, headers)IOError: ('http error', 302, 'Moved Temporously', )
这意味着您现在可以访问,因为您伪造了真实浏览器的请求.
<预><代码>>>>尝试:s = openAsOpera('http://wowcircle.com/?pmtry=1')除了:导入系统;ty, err, tb = sys.exc_info()>>>err.args[3].headers['服务器:nginx\r\n'、'日期:2014 年 4 月 5 日星期六 07:42:00 GMT\r\n'、'内容类型:文本/html\r\n'、'内容长度:154\r\n','连接:关闭\r\n','设置-Cookie:PMBC=9979187990a58a5bfdaa6d1380ad6156;path=/\r\n', '位置:http://wowcircle.com/?pmtry=1\r\n']一个需要注意的地方:重定向到这个位置:http://wowcircle.com/?pmtry=1
然后到 whis:http://wowcircle.com/?pmtry=2
.它计数.并且似乎在等待 cookie.
所以我的分析结果是:每次访问网站时不要忘记发送cookie.
Please, Help me!
I am using Python3.3 and this code:
import urllib.request
import sys
Open_Page = urllib.request.urlopen(
"http://wowcircle.com"
).read().decode().encode('utf-8')
And I take this:
Traceback (most recent call last):

urllib.error.HTTPError: HTTP Error 403: Forbidden
I understand, that I have no access to site wowcircle.com. But i want only to take source code! I believe that I can do it, without acess, but how?
I advise you to set the headers accordingly. Have a look what your browser sends (HTTP headers plugin).
A function may look like this:
def openAsOpera(url):
u = urllib.URLopener() # Python 3: urllib.request.URLOpener
u.addheaders = []
u.addheader('User-Agent', 'Opera/9.80 (Windows NT 6.1; WOW64; U; de) Presto/2.10.289 Version/12.01')
u.addheader('Accept-Language', 'de-DE,de;q=0.9,en;q=0.8')
u.addheader('Accept', 'text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/webp, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1')
f = u.open(url)
content = f.read()
f.close()
return content
This gets you around some errors on some webpages which expect more from a client than the basic version does.
Now I get this error:
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
s = openAsOpera('http://wowcircle.com/')
File "C:....pyw", line 522, in openAsOpera
f = u.open(url)
File "C:\Python27\lib\urllib.py", line 208, in open
return getattr(self, name)(url)
File "C:\Python27\lib\urllib.py", line 359, in open_http
return self.http_error(url, fp, errcode, errmsg, headers)
File "C:\Python27\lib\urllib.py", line 376, in http_error
return self.http_error_default(url, fp, errcode, errmsg, headers)
File "C:\Python27\lib\urllib.py", line 381, in http_error_default
raise IOError, ('http error', errcode, errmsg, headers)
IOError: ('http error', 302, 'Moved Temporarily', <httplib.HTTPMessage instance at 0x02C8F1C0>)
Which means that you get access now because you fake the request of a real browser.
>>> try: s = openAsOpera('http://wowcircle.com/?pmtry=1')
except: import sys; ty, err, tb = sys.exc_info()
>>> err.args[3].headers
['Server: nginx\r\n', 'Date: Sat, 05 Apr 2014 07:42:00 GMT\r\n', 'Content-Type: text/html\r\n', 'Content-Length: 154\r\n', 'Connection: close\r\n', 'Set-Cookie: PMBC=9979187990a58a5bfdaa6d1380ad6156; path=/\r\n', 'Location: http://wowcircle.com/?pmtry=1\r\n']
One thinkg to notice there: The redirect goes to this location: http://wowcircle.com/?pmtry=1
and then to whis: http://wowcircle.com/?pmtry=2
. It counts up. And seems to wait for the cookie.
SO the result of my analysis is: Do not forget to send the cookie every time you access the site.
