将结构转换为golang中的结构 [英] convert struct to struct in golang

问题描述

  type user1 struct {
姓氏字符串
姓氏字符串
用户名字符串
} 
 
类型user2结构{
姓氏字符串
姓氏字符串
} 
  

解决方案

最简单的方法是简单地执行 u2：= user2 {名字：u1.FirstName，LastName：u1.LastName} 。这是假设你不介意用户名在转换中丢失。

使用反射可以构建更通用的转换器，但我通常会尝试结构我的代码，所以它不需要。

trying to figure out what the best option is to convert one struct to another, Example

type user1 struct {
    FirstName string
    LastName string
    UserName string
}

type user2 struct {
    FirstName string
    LastName string
}

解决方案

The easiest is probably to simply do something like u2 := user2{FirstName: u1.FirstName, LastName: u1.LastName}. That is assuming you don't mind that the username is lost in the "conversion".

It's possible to build more general converters using reflection, but I would normally try to structure my code so it's not needed.
