scrapy 執(zhí)行了多個sprider

scrapy 執(zhí)行了多個sprider

結(jié)構(gòu)如上圖
run函數(shù)代碼如下：

from scrapy import cmdline
cmdline.execute('scrapy crawl testform'.split())

tesform代碼如下：

import scrapy
import requests
import json
class testform(scrapy.Spider):
    name = 'testform'
    def start_requests(self):
        url='https://www.jiqizhixin.com/graphql'
        headers={

        }
        payload={

            'query': "query Search($cursor: String, $count: Int, $keywords: String!, $filter_tags: [String]) {\n  elastic_search(first: $count, after: $cursor, keywords: $keywords, filter_tags: $filter_tags) {\n    edges {\n      node {\n        id\n        title\n        tag_list\n        content\n        author_name\n        categories\n        cover_image_url\n        published_at\n        friendly_path\n        __typename\n      }\n      __typename\n    }\n    total_count\n    pageInfo {\n      endCursor\n      hasNextPage\n      __typename\n    }\n    __typename\n  }\n}\n",

        }
        req=requests.post(url,json=payload,headers=headers)
        # req = requests.post(url, data=json.dumps(payload), headers=headers)
        yield scrapy.FormRequest(url,formdata=payload,headers=headers)
    def parse(self, response):
        print(response)

testlogin里面代碼是print(111)一句話
輸出結(jié)果如下：

可見先執(zhí)行了testlogin再執(zhí)行testform，為什么呢？？？？？？？？？？？？？？？？？
