How do I read the response headers returned from a PyCurl request?

推荐答案

有几种解决方案被丢弃）。这是一个
示例，使用选项HEADERFUNCTION，它允许您指示一个
函数来处理它们。

There are several solutions (by default, they are dropped). Here is an example using the option HEADERFUNCTION which lets you indicate a function to handle them.

其他解决方案是选项WRITEHEADER
WRITEFUNCTION）或将HEADER设置为True，以便它们与正文传送
。

Other solutions are options WRITEHEADER (not compatible with WRITEFUNCTION) or setting HEADER to True so that they are transmitted with the body.

#!/usr/bin/python

import pycurl
import sys

class Storage:
    def __init__(self):
        self.contents = ''
        self.line = 0

    def store(self, buf):
        self.line = self.line + 1
        self.contents = "%s%i: %s" % (self.contents, self.line, buf)

    def __str__(self):
        return self.contents

retrieved_body = Storage()
retrieved_headers = Storage()
c = pycurl.Curl()
c.setopt(c.URL, 'http://www.demaziere.fr/eve/')
c.setopt(c.WRITEFUNCTION, retrieved_body.store)
c.setopt(c.HEADERFUNCTION, retrieved_headers.store)
c.perform()
c.close()
print retrieved_headers
print retrieved_body
