Scrapy框架中的 UA伪装

例如：百度输入ip查看是自己本机的ip，通过UA伪装成其他机器的ip,

爬虫代码：

 1 import scrapy
 2 
 3 
 4 class UatestSpider(scrapy.Spider):
 5     name = 'UATest'
 6     # allowed_domains = ['www.xxx.com']
 7     start_urls = ['https://www.baidu.com/s?wd=ip']
 8     def parse(self, response):
 9         with open('./ip.html','w',encoding='utf-8')as fp:
10             fp.write(response.text)
11             print('over!!!')
