序

在写Go进行api接口请求的时候，往往需要将返回的json报文与结构体进行绑定。如果api接口返回的json参数较多，而且嵌套关系较为复杂，自己书写结构体的定义代码，不仅费时费力，还有着出现错误的风向……

一、解决办法

可以通过oktools在线实现json body到结构体的转换，网址为：https://oktools.net/
进入后页面如下，选择JSON转Go Struct：

在转换时，两种展开和嵌套两种方式本质上其实是一样的，就像面向对象和面向过程的区别一样，都可以实现样的功能，可以根据自己的习惯进行选择，具体如下：

• 转换-展开：可以看到结构体中定义了结构体
  
• 转换-嵌套：只有一个大结构体，但大结构体中嵌套定义了小结构体。
  
  这里给出相关代码的定义，读者可以自己测试进行验证。

二、相关测试代码

1. json body

转换得到的Go Struct如下：
