我尝试使用scrapy通过登录访问此网站：http://vietmessenger.com/cgi-bin/signin.cgi
在我刮网站之前，我使用这个scrapy python代码登录。但是，即使尝试了许多不同的方法，我总是得到这个错误（在response.body中）： 错误::将您的浏览器设置为接受 cookies ，重新加载并重试..
我可以确认，如果我在Safari浏览器中禁用cookie，我会收到同样的错误。我感谢你的帮助，我不知道还有什么可以尝试。
import scrapy
import re
import pickle
from scrapy.http import FormRequest
class LoginSpider(scrapy.Spider):
name = "ebooks"
start_urls = ["http://vietmessenger.com/cgi-bin/signin.cgi"]
def parse(self, response):
formdata = {"MEMBERID":"userid", "PASSWORD":"password"}
yield FormRequest.from_response(
response,
formdata = formdata,
callback = self.after_login)
def after_login(self, response):
#check if login is successful
print(response.status)
if b'ERROR::' in response.body:
self.logger.error('login failed')
return
这是日志：
