http.client.HTTPException：有超过100个标题

Question

因为谷歌没有发现任何关于错误的信息”http.client.HTTPException：有100多个标题”，我创建了这个问题。在

>>> import http.client as h
>>> conn = h.HTTPConnection("www.coursefinders.com")
>>> conn.request("HEAD","/")
>>> conn.getresponse();
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.4/http/client.py", line 1148, in getresponse
    response.begin()
  File "/usr/lib/python3.4/http/client.py", line 376, in begin
    self.headers = self.msg = parse_headers(self.fp)
  File "/usr/lib/python3.4/http/client.py", line 267, in parse_headers
    raise HTTPException("got more than %d headers" % _MAXHEADERS)
http.client.HTTPException: got more than 100 headers

这个异常意味着什么？我应该如何正确处理这种类型的错误？网站在浏览器中工作正常。在

Answer 1

在C:\Python27\Lib中将“\u MAXHEADERS”的值更改为1000或10000\httplib.py在

Answer 2

我本打算建议使用requests，但它是用http.客户端因为同样的原因失败了。为了验证问题是在库还是在服务器上，我尝试了telnet会话，结果如下：

Connection closed by foreign host.

因此，他们的服务器似乎配置错误，并正在喷出大量多余的Set Cookie头。在

似乎没有任何方法可以将httplib配置为接受大量的报头。我尝试过搜索没有使用httplib实现的替代HTTP库，但是没有任何运气。在

以下是一个不涉及更改库的py文件的解决方案：

import httplib  # or http.client if you're on Python 3
httplib._MAXHEADERS = 1000

把它放在代码的最上面
