scrapy之formrequest模拟post请求

先放代码吧，以后闲了再完善

def start_requests(self):
    url = "http://www.hebzx.gov.cn/specialnews.aspx?meetingtype=009001"
    yield scrapy.Request(url,callback=self.parse0)
def parse0(self,response):
    formdata = {"__EVENTTARGET":"AspNetPager1","__EVENTARGUMENT":"2"}
    return scrapy.FormRequest.from_response(
                response,
                formdata=formdata,
                callback=self.parse1
            )       
def parse1(self,response):
    print("1111111111111")
    print(response.text)
