如何从 Scrapy 中的请求获得响应? [英] How can I get the response from the Request in Scrapy?

问题描述

有什么办法可以从scrapy的Request函数中获取response.body?

Is there any way that I can get the response.body from the Request function in scrapy?

我有这个:

request = Request("http://www.example.com",  callback = self.mytest)

def mytest(self, response)
     return response.body

现在我想在 Python 变量中获取 response.body，我该如何获取?

Now I want to get response.body in a Python variable, How can I get that?

我想要类似的东西

myresponse = Request("http://www.example.com").get('response')

推荐答案

有没有办法从刚创建的 Request 中获取 Response? 没有，只​​有回调函数可以访问 Response.进入回调后，您可以通过 response.request 访问请求，但反之则不行.

Is there a way to get the Response from a Request you just created? No, only the callback function has access to the Response. Once inside the callback you can access the Request via response.request, but not vise-versa.
