Google 通过 Scrapy 进行身份验证
Google Authenticaion via Scrapy
我很好奇是否可以通过 scrapy 实现 google 身份验证。我尝试使用以下代码片段来实现。
我的代码：
import scrapy
from scrapy.http import FormRequest, Request
import logging
import json
class LoginSpider(scrapy.Spider):
name = 'hello'
start_urls = ['https://accounts.google.com']
handle_httpstatus_list = [404, 405]
def parse(self, response):
print('inside parse')
print(response.url)
return [FormRequest.from_response(response,
formdata={'Email': 'abc@gmail.com'},
callback=self.log_password)]
def log_password(self, response):
print('inside log_password')
print(response.url)
return [FormRequest.from_response(response,
formdata={'Passwd': 'password'},
callback=self.after_login)]
def after_login(self, response):
print('inside after_login')
print(response.url)
if "authentication failed" in response.body:
self.log("Login failed", level=logging.ERROR)
return
# We've successfully authenticated, let's have some fun!
else:
print("Login Successful!!")
if __name__ == '__main__':
process = CrawlerProcess({
'USER_AGENT': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36',
'DOWNLOAD_DELAY': 0.2,
'HANDLE_HTTPSTATUS_ALL': True
})
process.crawl(LoginSpider)
process.start()
但是当我 运行 脚本时，我得到了以下输出。

如有任何帮助，我们将不胜感激
错误 405 表示 URL 不接受 HTTP 方法，在您的情况下 POST 生成于 parse。
Google 默认登录页面比简单的 POST 表单复杂得多，在后台大量使用 JS 和 Ajax。要使用 Scrapy 登录，您必须使用 https://accounts.google.com/ServiceLogin?nojavascript=1 作为开始 URL。
