golang返回多个值问题 [英] golang return multiple values issue

问题描述

  func FindUserInfo（id string）（Info，bool）{
 it，present：= all [id] 
 return it，present 
} 
  

但这不是

  func FindUserInfo（id string）（Info，bool）{
 return所有[id] 
} 
  

是否有避免临时变量的方法？ p>

解决方案

您可以使用命名返回来保存几个按键：

 func FindUserInfo（id string）（i Info，ok bool）{
i，ok = all [id] 
 return 
} 
  

但除此之外，我不认为您想要的是什么。

I was wondering why this is valid go code:

func FindUserInfo(id string) (Info, bool) {
    it, present := all[id]
    return it, present
}

but this isn't

func FindUserInfo(id string) (Info, bool) {
    return all[id]
}

is there a way to avoid the temporary variables?

解决方案

You may save a couple of key strokes by using named returns:

func FindUserInfo(id string) (i Info, ok bool) {
    i, ok = all[id]
    return
}

But apart from that, I don't think what you want is possible.
