无法在python中的request.get()或request.post()上连接到代理错误 [英] Cannot connect to proxy error on requests.get() or requests.post() in python
问题描述
我有两个URL可以从中获取数据.使用我的代码，第一个URL有效，而第二个URL提供 ProxyError .
I have two URLs to fetch data from. Using my code, the first URL is working, whereas the second URL is giving ProxyError.
我正在Python 3中使用 requests 库，并尝试在Google和此处搜索问题，但没有成功.
I am using requests library in Python 3 and tried searching the problem in Google and here, but with no success.
我的代码段是:
import requests
proxies = {
'http': 'http://user:pass@xxx.xxx.xxx.xxx:xxxx',
'https': 'http://user:pass@xxx.xxx.xxx.xxx:xxxx',
}
url1 = 'https://en.oxforddictionaries.com/definition/act'
url2 = 'https://dictionary.cambridge.org/dictionary/english/act'
r1 = requests.get(url1, proxies=proxies)
r2 = requests.get(url2, proxies=proxies)
url1 正常工作，但是 url2 给出以下错误:
url1 works fine, but url2 gives following error:
ProxyError: HTTPSConnectionPool(host='dictionary.cambridge.org', port=443): Max retries exceeded with url: /dictionary/english/act (Caused by ProxyError('Cannot connect to proxy.', RemoteDisconnected('Remote end closed connection without response',)))
使用 request.post()

请解释一下为什么会发生这种情况，并且两个URL的握手之间有什么区别吗?
Please explain me why this is happening, and is there any difference between the handshaking of both the URLs?
urllib.request.urlopen 工作正常，所以我明确地使用 requests
urllib.request.urlopen is working fine, so I am explicity looking for answers using requests
推荐答案
在 User-Agent 中使用headers关键字参数时，我能够对 url2 进行有效的响应字符串设置为 Chrome .
I was able to illicit a valid response for url2 when using headers keyword argument with User-Agent string set to Chrome.
r2 = requests.get(url2, proxies=proxies, headers={'User-Agent': 'Chrome'})
要回答您的第一个问题，发生这种情况的可能原因与服务器端设置有关.可能配置为不接受来自未知代理的请求或缺少 User-Agent 标头的请求.
To answer your first question, possible reason for this happening is related to server-side settings. It might be configured not to accept requests originating from unknown agents or requests with a missing User-Agent header.
