在 Scrapy 中发送帖子请求 [英] Send Post Request in Scrapy

问题描述

我正在尝试从 google Play 商店抓取最新评论，然后我需要提出发布请求.

I am trying to crawl the latest reviews from google play store and to get that I need to make a post request.

使用 Postman，它可以工作，我得到了想要的响应.

With the Postman, it works and I get desired response.

但是终端中的 post 请求给了我一个服务器错误

but a post request in terminal gives me a server error

例如:此页面 https://play.google.com/store/apps/details?id=com.supercell.boombeach

curl -H "Content-Type: application/json" -X POST -d '{"id": "com.supercell.boombeach", "reviewType": '0', "reviewSortOrder": '0', "pageNum":'0'}' https://play.google.com/store/getreviews

给出服务器错误和

Scrapy 只是忽略了这一行:

Scrapy just ignores this line:

frmdata = {"id": "com.supercell.boombeach", "reviewType": 0, "reviewSortOrder": 0, "pageNum":0}
        url = "https://play.google.com/store/getreviews"
        yield Request(url, callback=self.parse, method="POST", body=urllib.urlencode(frmdata))

推荐答案

确保 formdata 中的每个元素都是 string/unicode 类型

Make sure that each element in your formdata is of type string/unicode

frmdata = {"id": "com.supercell.boombeach", "reviewType": '0', "reviewSortOrder": '0', "pageNum":'0'}
url = "https://play.google.com/store/getreviews"
yield FormRequest(url, callback=self.parse, formdata=frmdata)

我认为这样做

In [1]: from scrapy.http import FormRequest

In [2]: frmdata = {"id": "com.supercell.boombeach", "reviewType": '0', "reviewSortOrder": '0', "pageNum":'0'}

In [3]: url = "https://play.google.com/store/getreviews"

In [4]: r = FormRequest(url, formdata=frmdata)

In [5]: fetch(r)
