将标签应用于每个结构体中的每个字段。

Apply tag to every field in every struct

问题

是否可以在每个结构体/多个结构体上应用默认的字段标签,而无需手动输入,并且保持代码更清晰?

例如:当我需要默认情况下将omitempty应用于每个结构体时

type SomeStruct struct {
    FieldOne string `json:"field_one,omitempty"`
    FieldTwo string `json:"field_two,omitempty"`
    FieldThree string `json:"field_three,omitempty"`
}

编写用于解析所有JSON响应并删除空字段的API中间件似乎非常耗费资源。

英文:

Is it possible to apply a default struct field tag to every struct / many structs without having to type it out, and also keeps code cleaner.

Eg: when i need omitempty to be applied by default to every struct

type SomeStruct struct {
    FieldOne string `json:"field_one,omitempty"`
    FieldTwo string `json:"field_two,omitempty"`
    FieldThree string `json:"field_three,omitempty"`
}

Writing middleware for my API to parse all JSON responses, then remove empty fields seems very expensive.
