英文:
pass constant list (immutable) in variadic in Go
问题
var state = [...]string{
"new",
"submitted",
"approved",
"rejected",
}
In(values ...interface{}) {
return
}
我需要在Go语言中将一个不可变列表传递给一个可变参数函数。
英文:
var state = [...]string{
"new",
"submitted",
"approved",
"rejected",
}
In(values ...interface{}) {
return
}

你不能将字符串的切片或数组传递给接受可变参数列表的函数，该函数的参数类型为interface{}。你需要先创建一个[]interface{}，然后将其传递进去：
args := make([]interface{}, len(state))
for i, x := range state {
args[i] = x
}
In(args...)
英文:
You cannot pass a slice or array of strings to a function that accepts a variadic argument list of interface{} types. You have to first create an []interface{}, and pass that:
args:=make([]interface{},len(state))
for i,x:=range state {
args[i]=x
}
In(args...)
