检查数组中每个字符串的多个正则表达式

Question

我有一个角色数组，如下所示：

["ROLE_ADMIN", "ROLE_USER_ADMIN_MARKETING"]

我需要的:
我需要检查此数组中的 string 是否完全匹配。如果是，return true，如果不是return false。

警告:
正如您在下面看到的，roles 以相同的文本开头，因此检查完全相同的字符串很重要。

为什么我的console.log在这里返回true？也许我不应该使用 switch 案例？

export const ROLE_ADMIN = "ROLE_ADMIN";
export const ROLE_USER_ADMIN = "ROLE_USER_ADMIN";
export const ROLE_MARKETING = "ROLE_USER_ADMIN_MARKETING";
export const ROLE_TECHNICAL = "ROLE_USER_ADMIN_TECHNICAL";

const roles: string[] = JSON.parse(localStorage.getItem("roles"));

class UserRole {
    static regexAdmin = new RegExp(`\\b${ROLE_ADMIN}\\b`);
    static regexUserAdmin = new RegExp(`\\b${ROLE_USER_ADMIN}\\b`);
    static regexMarketing = new RegExp(`\\b${ROLE_MARKETING}\\b`);
    static regexTechnical = new RegExp(`\\b${ROLE_TECHNICAL}\\b`);

    public static hasAuthorization(role: string): boolean {
        for (const role of roles) {
            switch (true) {
                case UserRole.regexAdmin.test(role):
                    return true;
                case UserRole.regexUserAdmin.test(role):
                    return true;
                case UserRole.regexMarketing.test(role):
                    return true;
                case UserRole.regexTechnical.test(role):
                    return true;
                default:
                    return false;
            }
        }
    }
}

export const hasAdmin = UserRole.hasAuthorization(ROLE_USER_ADMIN);

console.log(hasAdmin); // THIS RETURNS TRUE

Answer 1

这是一个简单的

["ROLE_ADMIN", "ROLE_USER_ADMIN_MARKETING"].includes(ROLE_USER_ADMIN)

例子：

let ROLE_USER_ADMIN = "ROLE_ADMIN";

console.log(["ROLE_ADMIN", "ROLE_USER_ADMIN_MARKETING"].includes(ROLE_USER_ADMIN));

ROLE_USER_ADMIN = "ROLE_ADMIN2";

console.log(["ROLE_ADMIN", "ROLE_USER_ADMIN_MARKETING"].includes(ROLE_USER_ADMIN));


ROLE_USER_ADMIN = "ROLE_ADMI";

console.log(["ROLE_ADMIN", "ROLE_USER_ADMIN_MARKETING"].includes(ROLE_USER_ADMIN));

完整的代码可以是

export const ROLE_ADMIN = "ROLE_ADMIN";
export const ROLE_USER_ADMIN = "ROLE_USER_ADMIN";
export const ROLE_MARKETING = "ROLE_USER_ADMIN_MARKETING";
export const ROLE_TECHNICAL = "ROLE_USER_ADMIN_TECHNICAL";

const roles: string[] = JSON.parse(localStorage.getItem("roles"));

class UserRole {
    public static hasAuthorization(role: string): boolean {
        return roles.includes(role);
    }
}

export const hasAdmin = UserRole.hasAuthorization(ROLE_USER_ADMIN);

console.log(hasAdmin); // THIS RETURNS TRUE
