如何通過TOR通過Polipo使用Scrapy連接到https站點？

Question

不能完全確定問題出在哪里。

運行Python 2.7.3和Scrapy 0.16.5

我創建了一個非常簡單的Scrapy Spider，以測試與本地Polipo代理的連接，以便我可以通過TOR發送請求。 我的蜘蛛的基本代碼如下：

from scrapy.spider import BaseSpider

class TorSpider(BaseSpider):
    name = "tor"
    allowed_domains = ["check.torproject.org"]
    start_urls = [
        "https://check.torproject.org"
    ]

    def parse(self, response):
        print response.body

對於我的代理中間件，我定義了：

class ProxyMiddleware(object):
    def process_request(self, request, spider):
        request.meta['proxy'] = settings.get('HTTP_PROXY')

我在設置文件中的HTTP_PROXY = 'http://localhost:8123'定義為HTTP_PROXY = 'http://localhost:8123' 。

現在，如果我將起始URL更改為http://check.torproject.org ，則一切正常，沒有問題。

如果我嘗試針對https://check.torproject.org運行，每次都會收到400 Bad Request錯誤（我也嘗試過不同的https：//站點，並且所有站點都有相同的問題）：

只是要仔細檢查我的TOR / Polipo設置是否有問題，我可以在終端中運行以下curl命令，並進行正常連接： curl --proxy localhost:8123 https://check.torproject.org/

關於這里有什么問題的任何建議嗎？

Answer 1

嘗試

rq.meta['proxy'] = 'http://127.0.0.1:8123'

就我而言，這是可行的
