个性签:顺境不惰,逆境不馁,以心制境,万事可成。——曾国藩
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
