去检查字符串中是否有字符串

Question

As a preface I'm coming from python, where I would have a list with my values instead of string slices and do "if x in list". Please tell me if I'm doing this wrong.

I need to take input from the user, if it's contained in my sliced string then break out of my loop and continue, otherwise prompt the user again. Right now I have this

package main

import (
    "bufio"
    "fmt"
    "os"
    "os/exec"
    "strings"
)

func main() {
    reader := bufio.NewReader(os.Stdin)
    foundfdb := false
    fdbslices := []string{"f", "d", "b", "files", "directories", "both"}

    for {
        fmt.Print("Files, Directories, or Both: ")
        fdb, _ := reader.ReadString('
')
        fdb = strings.ToLower(fdb)
        for i := range fdbslices {
            if strings.ContainsAny(fdbslices[i], fdb) {
                foundfdb = true
            }
        }
        if foundfdb = true {
            break
        }
    }
}

It seems ContainsAny() is giving me some false positives. There's got to be an easier way to do this, or is there?

Answer 1

ContainsAny allows you to look for a specific character is in a specific string, and I do not think that's what you want. For one of my projects, I implemented a function to look for a string in a slice:

func InArray(a []string, e string) bool {
    for _, x := range a {
        if x == e {
            return true
        }
    }
    return false
}
