Missing Field or Method

问题

var client := http.Client

由于某种原因,这段代码出现了错误消息“缺少变量或初始化”。有人可以告诉我为什么吗?我不明白我做错了什么。

英文:
var client := http.Client

For whatever reason this code is giving the error message missing variable or initialization. Can someone enlighten me on why? I'm not understanding what I have done wrong.

在Go语言中,我们使用:=var =来初始化变量。在你的情况下,你可以将其重写为:

var client = http.Client{}

或者

client := http.Client{}

这两种方式都会触发变量的类型推断。你也可以使用var和类型来显式声明一个类型。在你的情况下,如果你想要强制指定类型,你可以这样写:

var client http.Client = http.Client{}
英文:

In Go we use := or var = for initializing variables. In your case you can re-write it to be:

var client = http.Client{}

or

client := http.Client{}

Either of these will trigger type inference of the variable. You can use var with a type to explicitly declare a type as well. In your case if you wanted to enforce the type you could write:

var client http.Client = http.Client{}
