Question

不完全确定问题在这里。

运行Python 2.7.3和Scrapy 0.16.5

我创建了一个非常简单的Scrapy蜘蛛来测试连接到我的本地Polipo代理，以便我可以通过TOR发送请求。我蜘蛛的基本代码如下：

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

对于我的代理中间件，我已定义：

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

我的设置文件中的HTTP_PROXY定义为HTTP_PROXY = 'http://localhost:8123'。

现在，如果我将起始网址更改为http://check.torproject.org，一切正常，没问题。

如果我尝试针对https://check.torproject.org运行，每次都会收到400 Bad Request错误（我也尝试过不同的https：//网站，并且所有网站都有同样的问题）：

为了仔细检查我的TOR / Polipo设置是不是有问题，我可以在终端中运行以下curl命令，并连接正常：curl --proxy localhost:8123 https://check.torproject.org/

有关这里有什么问题的任何建议吗？

Answer 1

尝试

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

就我而言，这是有效的
