我是scrapy的新手，所以这个问题似乎太简单了。我从http网站下载没有问题。但是当我尝试对this url执行相同操作时，我收到以下错误。
代码：
from scrapy.spider import BaseSpider
class Bundspider(BaseSpider):
name="bund"
allowed_domains=["www.bundesanzeiger.de"]
start_urls=[
"https://www.bundesanzeiger.de/ebanzwww/wexsservlet?page.navid=to_nlp_start"
]
def parse(self, response):
filename = response.url.split("/")[-2]
open(filename, 'wb').write(response.body)
错误：
