我正在使用scrapy爲architonic * com的產品刮目錄頁面。但是，我想以每行csv顯示這些產品。在當前形勢下，從給定的分類頁面的所有品牌都在「品牌」一欄，而我想有一個像這樣的輸出：Scrapy：每個項目一行
{'brand': [u'Elisabeth Ellefsen'],
'title': [u'Up chair I 907'],
'img_url': [u'http://image.architonic.com/img_pro1-1/117/4373/t-up-06f-sq.jpg'],
'link': [u'http://www.architonic.com/pmsht/up-chair-tonon/1174373']
}
我試圖與項目裝載機打（添加default_output_processor = TakeFirst（ ）），添加'yield item'（查看註釋代碼）並搜索兩天以找到解決方案，但沒有運氣。希望有人願意幫助我。任何幫助真的很感激。
我輸出看起來是這樣的：

請附上您的items.py文件，因爲這個代碼將不能沒有它運行。 :) – Talvalin
謝謝，我添加items.py！ :) – Joost
CSV？但是你的數據結構是JSON。那麼，怎麼了？如果你想要單獨的項目列表，你應該首先獲取項目容器，並從中提取所需的數據。 – Denis
