我想在不下載的情況下獲得影像大小，可以嗎？

def parse_product(self, response):
images = response.css(".swiper-slide::attr(data-large)").getall()
image1 = images[0]
image_size=yield Request(image1, method="HEAD", callback=self.callback)
uj5u.com熱心網友回復：
您可以使用HEAD方法。
import scrapy
class ExampleSpider(scrapy.Spider):
name = 'example_spider'
def start_requests(self):
images_urls = [
'http://wallpapercave.com/wp/wp1809904.jpg',
'https://i2.wp.com/www.otakutale.com/wp-content/uploads/2015/10/One-Punch-Man-Anime-Magazine-Visual-01.jpg',
'https://thedeadtoons.com/wp-content/uploads/2020/06/One-Punch-Man-Season-3.jpg'
]
for url in images_urls:
yield scrapy.Request(url=url, method='HEAD')
def parse(self, response, **kwargs):
yield {
'Content-Length': response.headers['Content-Length']
}
輸出：
