我不确定我是否了解您的需求。
可能是这样的事情？可能需要做一些工作，例如使指向结构的指针切片而不是结构的切片以防止分配和复制，错误处理，更多自定义逻辑来转换值，匿名化/封装转换中间使用的私有结构，向其中添加json标签这些结构等
我在IncomingPaylod上为Data字段创建了自定义的Unmarshaller：解析期望的数据，将其转换为[]
MyData并使用它更新Data字段。
我为Expected_data和Expected_services_with_info创建了自定义Unmarshallers，因为我们希望它作为值数组（3个值：字符串，整数和[字符串数组，整数（？），整数]），但是我想将其转换为漂亮的结构。如果您不喜欢它，可以将其删除，将所需的数据解组到[]
interface {}，并像[] interface {} {string，int，[] interface {}
{string，int，int}}一样使用它。容易出错，因此我更喜欢结构，它更易于阅读，维护和重构（我认为您的应用程序中包含更多字段）。
