去将reflect.Value从字符串转换为int

Question

I am getting an error like this

reflect.Value.Convert: value of type string cannot be converted to type int
goroutine 6

When I am running this code

param := "1" // type string
ps := fn.In(i) // type int

if !reflect.TypeOf(param).ConvertibleTo(ps) {
    fmt.Print("Could not convert parameter.
") // this is printed
}
convertedParam := reflect.ValueOf(param).Convert(ps)

Can I do this in some way without creating a switch/case and multiple lines of code for converting to each type? I am just looking for the easiest/best way to do this.

There are specific rules for type conversion. Strings cannot be converted to numeric values.

Use the strconv package to read a numeric value from a string.
