使用scrapy爬取无法保存图片

使用scarpy爬取图片无法保存
itme能传入管道但是保存不到本地文件夹
主代码

```python
import scrapy
from ..items import HgfhItem

class XiaoshuSpider(scrapy.Spider):
    name = 'xiaoshu'
    #allowed_domains = ['www.baidu.com']
    url='https://www.xintp.com/bizhi/shoujibizhi/page/{}/'
    cc=2
    start_urls = [url.format(str(cc))]

    def parse(self, response):
        ff= response.xpath('//*[@id="main"]/article/div/figure/span/a/@href').extract()
        for ll in ff:
            yield scrapy.Request(url=ll,callback= self.parse_a,dont_filter= True  )
        # if self.cc<=222 :
        #     self.cc+=1
        #     yield scrapy.Request(url=self.url.format(str(self.cc )),callback=self.parse,dont_filter= True  )
    def parse_a(self,resource):
        try:
            cj=resource.xpath('//*[@id="main"]/article/div/div[3]/a/@href').extract()
            del cj[0],cj[-1]
            for lk in cj:
                yield scrapy.Request(url=lk ,callback= self.parse_b,dont_filter= True )
        except :
            lj=resource.url
            print('没有下一页')
            yield scrapy.Request(url=lj,callback= self.parse_b,dont_filter= True )
    def parse_b(self,resource):
        oi = resource.xpath('//*[@id="main"]/article/div/div[2]/div/figure/a/img/@src | //*[@id="main"]/article/div/div[2]/div/p/a/img/@src').extract()
        itme = HgfhItem()
        itme['file'] =oi
        yield itme
        pass

time代码

import scrapy
class HgfhItem(scrapy.Item):
    # define the fields for your item here like:
    file= scrapy.Field()
    pass

管道代码

from scrapy.pipelines.images import ImagesPipeline
import  scrapy
from scrapy.exceptions import  DropItem

class ImgePipeline(ImagesPipeline):
    def get_media_requests(self, item, info):
        print(item['file'])
        for url in item ['file']:
            yield scrapy.Request(url=url,dont_filter= True )
    def file_path(self, request, response=None,info=None):
        yi='meinv'+request.url.split('/')[-1]
        print(yi)
        return yi
    def item_completed(self, results, item, info):
        return item
    def __del__(self):
        print('ok')

设置

ITEM_PIPELINES = {
    'hgfh.pipelines.ImgePipeline': 300,
}
IMAGES_STORE = './hgfhimg'
