Go中的多个nil，nil ...检测

In go you can have several returns like:

func getAdressParts() (plz *string, street *string) {
    return nil, nil
}

func main() {

    //if getAdressParts() == nil, nill {
    //   println(true)
    //} else {
    //   println(false)
    //}

    // As already suggested the answer is:
    if plz, street := getAdressParts(); plz == nil && street == nil {
        println("Hurra")
    } else {
        println("nope")
    }

}

is there any way to check both inline for nil like:

if getAdressParts() == nil, nil {
   ...
}

you can play with example here: https://play.golang.org/p/xbHCxl_AJyw

Not quite that succinctly, but yes:

if plz, street := getAdressParts(); plz == nil && street == nil {
    // Do stuff
}

This is demonstrated in the Go tour and the Go spec.

Note as icza points out, this doesn't make any sense for strings (which can't be nil), but the syntax you'd use for a valid test is as above.

string can't be nil, but i think you'll need to do

if a, b := getAdressParts(); a == "" && b == "" {
    println("nil")
}
