向spider中传递参数

1.这里采用run.py脚本方式

 1 # 通过CrawlerProcess同时运行几个spider
 2 import scrapy
 3 from scrapy.crawler import CrawlerProcess
 4 from scrapy.utils.project import get_project_settings
 5 from spiders.test import TestSpider
 6 
 7 name = '小明'
 8 process = CrawlerProcess(get_project_settings())
 9 process.crawl(TestSpider,name) # 注意引入
10 process.start()

2.修改spider的初始化函数test.py

class TestSpider(scrapy.Spider):
    def __init__(self,name):
        self.urls ='https://www.xxxxxx.com/actor=%s&page=1'%(name)

3.运行可得self.urls的值为：
