我正在嘗試使用scrapy下載圖像，但返回以下錯誤：raise NotSupported("Response content isn't text")scrapy.exceptions.NotSupported: Response content isn't text2018-11-30 14:36:09 [scrapy.core.scraper] ERROR: Spider error processing <GET https://www.example.bla/39307b2103.jpg> 這是我正在使用的相應代碼：...myitem['i10_img']       = 'https://www.example.de' + response.css("#fullscreen_img::attr(src)").extract_first()[2:]yield scrapy.Request(myitem['i10_img'],callback=self.parseImages,  meta={'item': myitem})return myitemdef parseImages(self, response):    for elem in response.xpath("//img"):        img_url = elem.xpath("@src").extract_first()        yield ImageItem(image_urls=[img_url])項目.pyclass ImageItem(scrapy.Item):image_urls = scrapy.Field()images = scrapy.Field()我需要在 yield 命令中進行一些調整嗎？
