我的蜘蛛可以工作，但我无法下载我在.html文件中爬行的网站的主体。如果我写self.html_fil.write('test')，那么它工作得很好。我不知道如何把薄纱改成细绳。
我使用Python3.6
蜘蛛：class ExampleSpider(scrapy.Spider):
name = "example"
allowed_domains = ['google.com']
start_urls = ['http://google.com/']
def __init__(self):
self.path_to_html = html_path + 'index.html'
self.path_to_header = header_path + 'index.html'
self.html_file = open(self.path_to_html, 'w')
def parse(self, response):
url = response.url
self.html_file.write(response.body)
self.html_file.close()
yield {
'url': url
}
