如何设置使文件存到指定地方？

h1=scrapy.Field()

假如我要存到当前目录下的h1文件夹

from scrapy.spiders import Spider

from scrapy import Request
from ..items import DoubanImgsItem
 
 
class download_douban(Spider):
    name = 'download_douban'
 
    default_headers = {
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',

    }
 
    def __init__(self, url='1638835355', *args, **kwargs):
        self.allowed_domains = ['douban.com']
        self.start_urls = [
            'http://www.douban.com/photos/album/%s/' % (url)]
        self.url = url
        # call the father base function
 
        # super(download_douban, self).__init__(*args, **kwargs)
 
    def start_requests(self):
 
        for url in self.start_urls:
            yield Request(url=url, headers=self.default_headers, callback=self.parse)
 
    def parse(self, response):
        list_imgs = response.xpath('//div[@class="photolst clearfix"]//img/@src').extract()
        if list_imgs:
            item = DoubanImgsItem()
            item['image_urls'] = list_imgs
            yield item
 

如果响应内容是文件流的话，可以直接操作存储为文件的，比如这段应用：

#遍历保存当前页面的图片
	for img in all_img:
		src = img['src']
		img_url = src
		
		#保存图片到本地，获取 / 以后的最后一部分的文件名
		path = "./image/"+img_url.split('/')[-1]

		try:
			if not os.path.exists(path):
				r = requests.get("https:"+img_url)
				with open(path,'wb') as f:
					f.write(r.content)
					f.close()
					print('文件保存成功')
			else:
				print('文件已存在')
		except:
			print('失败')
		
		#返回下一页连接 
		return next_page_url
