如何动态调用变量？

I have two variables:

somethingA := 123
somethingB := 456

This two variables are filled though the system and lets presume that you have third variable:

type := "A"

With third variable you want to call somethingA but not like following:

if type == "A" {
    return somethingA
}else{
    return somethingB
}

but something like:

return something{type}

Is something like this possible in go?

Thank you

No.

All ways to do something like this boils down to the solution you showed.

use a map

package main

import (
    "fmt"
)

func main() {
        x:=make(map[string]int)
        x["SomethingA"]=123
        x["SomethingB"]=456
    fmt.Println(x["SomethingA"])
    fmt.Println(x["SomethingB"])
}
