如何使用scrapy保存图像

import scrapy
from scrapy.pipelines.images import ImagesPipeline

class MyImagesPipeline(ImagesPipeline):
    def file_path(self, request, response=None, info=None):
        # 定义保存图像的路径和文件名
        image_name = request.url.split('/')[-1]
        return image_name

ITEM_PIPELINES = {
    'myproject.pipelines.MyImagesPipeline': 1,
    # 其他的管道类...
}

class MySpider(scrapy.Spider):
    name = "myspider"
    start_urls = [
        'http://example.com/page1.html',
    ]

    def parse(self, response):
        # 提取图像URL
        image_urls = response.css('img::attr(src)').getall()
        
        # 构建图像请求并回调处理方法
        for url in image_urls:
            yield scrapy.Request(url, self.parse_image)

    def parse_image(self, response):
        # 在回调方法中，提取图像数据并传递给管道类进行处理
        yield {
            'image': response.body
        }

scrapy crawl myspider
