Question

我才刚刚开始使用API，并且有一些我想从客户网站中提取的产品列表。一切正常，但我意识到如果将它们直接上载到数据库中，它们返回URL的方式将不起作用，因为它们前面有一个“ //”并且浏览器会自动假定其为文件而不是https：// 。我试图遍历返回的值并搜索所有URL，然后删除//或在其前面添加https:。请注意，所有URL都显示在JSON内嵌套的列表中

目前，我已经编写了可以遍历当前JSON的代码，但是JSON的结构并不总是相同的，并且密钥根据产品类别甚至产品而变化。我希望能够遍历JSON，确定它是否为列表，遍历该列表以及更改URL和SRC密钥。除非有其他解决方法！

Answer 1

您可以将整个内容制作为str并替换：

import json

json.loads(json.dumps(res).replace('//', ''))

部分输出：

...
