How to return multiple Values in multiple lines in GoLang?
if x == y {
req, _ := cgi.Request()
return req.FormValue("a"),
req.FormValue("b"),
req.FormValue("c"),
req.FormValue("d"),
req.FormValue("e"),
} else {
...
}
./example.go:9:3: syntax error: unexpected }, expecting expression
This is not a composite literal or function call, you must not put a trailing comma after the last line:
return req.FormValue("a"),
req.FormValue("b"),
req.FormValue("c"),
req.FormValue("d"),
req.FormValue("e")
See an example:
func f() (int, int, string) {
return 1,
2,
"3"
}
Testing it:
fmt.Println(f())
Output (try it on the Go Playground):
1 2 3
