urllib2/requests 和 HTTP 相对路径 [英] urllib2/requests and HTTP relative path

问题描述

如何强制 urllib2/requests 模块使用相对路径而不是完整/绝对 URL??

How can I force urllib2/requests modules to use relative paths instead of full/absolute URL??

当我使用 urllib2/requests 发送请求时，我在代理中看到它解析为:

when I send request using urllib2/requests I see in my proxy that it resolves it to:

GET https://xxxx/path/to/something HTTP/1.1

不幸的是，我将它发送到的服务器无法理解该请求并给了我奇怪的 302.我知道它在 RFC 中，它只是不起作用，我正在尝试在 python 代码中修复它.我无权访问该服务器.

Unfortunately, the server to which I'm sending it, cannot understand that request and gives me weird 302. I know it's in RFC, it just doesn't work and I'm tryign to fix it in python code. I don't have access to that server.

相对路径，效果很好

GET /path/to/something HTTP/1.1
Host: xxxx

那么如何强制 requests/urllib2 不使用绝对路径?并使用简单的相对路径?

So how can I force requests/urllib2 to not use absolute paths? and use simple relative paths?

推荐答案

以下代码可能适用于您的情况:

Probably the following code would do for your case:

from urlparse import urljoin
import requests

class RelativeSession(requests.Session):
    def __init__(self, base_url):
        super(RelativeSession, self).__init__()
        self.__base_url = base_url

    def request(self, method, url, **kwargs): 
        url = urljoin(self.__base_url, url)
        return super(RelativeSession, self).request(method, url, **kwargs)

session = RelativeSession('http://server.net')
response = session.get('/rel/url')
