元帅嵌入式结构 [英] Marshal Embedded Struct

问题描述

我正在玩耍以了解嵌入如何工作。 http://play.golang.org/p/oHOim4G1-l

当我编组Child时，将它编组为 {} 。为什么它名帅这样？

解决方案

您JSON字典是空的，因为没有一个结构的字段（或任何嵌入在结构内部结构）是导出。

如果您将字段名称更改为以大写字母开头，那么编码/ json 模块将能够看到它们。当然，因为你也有一些称为名称和值的方法，所以你需要给它们一些东西避免冲突。

I was playing around to learn how embedding works. http://play.golang.org/p/oHOim4G1-l

When I marshalled Child struct it marshals as {}. Why does it marshal like this?

解决方案

Your JSON dictionary is empty because none of the fields of the struct (or any of the structures embedded inside the struct) are exported.

If you change the field names to start with an upper case letter, then the encoding/json module will be able to see them. Of course since you've also got methods called Name and Value, you'll need to call them something else to avoid a conflict.
