Switch or operator compiler error

问题

我有以下代码,编译器报错。

switch req.Method {
    case "POST" || "PUT" || "DELETE":
        if req.Header.Get("Content-Type") != "application/json" {
            return handleErr(req)
        }
}

编译器错误信息:

..\..\controllers\routes\header.go:59: invalid operation: "POST" || "PUT" (operator || not defined on string)

我是不是错误地使用了或运算符?

英文:

I have following code that compiler complain.

switch req.Method {
        case "POST" || "PUT" || "DELETE":
            if req.Header.Get("Content-Type") != "application/json" {
                return handleErr(req)
            }
    }

Compiler error message

..\..\controllers\routes\header.go:59: invalid operation: "POST" || "PUT" (operator || not defined on string)

Do I use OR operator in wrong way?

只需使用逗号 , 替代 ||

case "POST", "PUT", "DELETE":

参见switch语句参考

英文:

Just use comma , instead of ||.

case "POST", "PUT", "DELETE":

See switch statement reference.
