我正在尝试使用 go-playground/validator/v10 包验证 Golang 中的结构字段。具体来说，我想使用 oneof 标签来验证字段值是否与预定义值之一匹配，其中包括带单引号 (') 的字符串。这是我使用的代码：

package main

import (
    "fmt"

    "github.com/go-playground/validator/v10"
)

// Struct with validation tag
type Award struct {
    Title string `validate:"oneof=palm'dor level'dor 'state award'"`
}

func main() {
    validate := validator.New()

    // Test cases
    testCases := []Award{
        {"palm'dor"},    // Expected: Valid
        {"level'dor"},   // Expected: Valid
        {"state award"}, // Expected: Valid
        {"other"},       // Expected: Invalid
    }

    for _, testCase := range testCases {
        err := validate.Struct(testCase)
        if err != nil {
            fmt.Printf("Input: %q - Invalid (%v)\n", testCase.Title, err)
        } else {
            fmt.Printf("Input: %q - Valid\n", testCase.Title)
        }
    }
}

预期行为：程序应验证“palm'dor”、“level'dor”和“state award”是否为有效输入。任何其他值都应标记为无效。

问题：当我运行该程序时，我得到以下输出：

Input: "palm'dor" - Invalid (Key: 'Award.Title' Error:Field validation for 'Title' failed on the 'oneof' tag)
Input: "level'dor" - Invalid (Key: 'Award.Title' Error:Field validation for 'Title' failed on the 'oneof' tag)
Input: "state award" - Valid
Input: "other" - Invalid (Key: 'Award.Title' Error:Field validation for 'Title' failed on the 'oneof' tag)
