scrapy填写POST表格

我尝试使用scrapy填写POST表格,试图预订火车票。

我认为FormRequest类可以做到这一点,但我不能处理javascript表单。 Scrapy爬虫没有返回任何东西。

我使用的文件足以发送表格。

import scrapy

from scrapy.item import Item, Field
from scrapy.http import FormRequest
from scrapy.spider import BaseSpider

class SncfItem(Item):
 title = Field()
 link = Field()
 desc = Field()

class SncfSpider(scrapy.Spider):
name = "sncf"
allowed_domains = ["voyages-sncf.com"]
start_urls = (
    'http://www.voyages-sncf.com/billet-train',
)

def parse(self, response):

    yield FormRequest.from_response(response,
                                    formname='saisie',
                                    formdata={'ORIGIN_CITY': 'Gare de Lyon (Paris)',
                                              'DESTINATION_CITY': 'Lyon Part-Dieu',
                                              'OUTWARD_DATE': '03.06.2015'},
                                    callback=self.parse1)

def parse1(self, response):
    print response.status

如果我在使用mySpider时错过了一步,有人能告诉我吗?

非常感谢任何帮助 感谢' S

您正在获取重定向,因为日期格式无效。

我在Scrapy shell中重播了该请求,执行以下操作:

ce::string process_name;

查看结果,我看到了日期的验证错误消息,说:“Le format de la date d'aller que vous avez saisi est wrong。Nous vousinvitonsàutiliserle calendrier。”
