在Scrapy Pipeline中，return super().process_item是什么意思？

Question

我发现了一个 scrapy pipelines 代码：

class SomeImagePipeline(ImagePipeline):
    ....
    ....
    def process_item(self, item, spider):
        return super(SomeImagesPipeline, self).process_item(item, spider)

“super(SometImes Pipeline, self).process_item(item, spider)”是什么意思？？

Answer 1

根据standard documentation on super，超级方法：

Return a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class.

因此，return super(SomeImagesPipeline, self).process_item(item, spider) 调用基础 class 的 process_item 方法，即 ImagePipeline 和 return 其 return 对象。
