我在做一個蜘蛛網，有一個問題：我試過了擷取一組html資料。以及它包含發送ajax所需的id請求。但是，當我試圖将ajax資料與html中獲得的其他資料放在一起時，結果就是這樣錯了，怎麼了我能解決嗎？我的代碼是：class DoubanSpider(scrapy.Spider):
name = "douban"
allowed_domains = ["movie.douban.com"]
start_urls = ["https://movie.douban.com/review/best"]
def parse(self, response):
for review in response.css(".review-item"):
rev = Review()
rev['reviewer'] = review.css("a[property='v:reviewer']::text").extract_first()
rev['rating'] = review.css("span[property='v:rating']::attr(class)").extract_first()
rev['title'] = review.css(".main-bd>h2>a::text").extract_first()
number = review.css("::attr(id)").extract_first()
f = scrapy.Request(url='https://movie.douban.com/j/review/%s/full' % number,
callback=self.parse_full_passage)
rev['comment'] = f
yield rev
def parse_full_passage(self, response):
r = json.loads(response.body_as_unicode())
html = r['html']
yield html
