您可以尝试利用afterHook，如

class UpdateUserRequest extends FormRequest
{    
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array<string, mixed>
     */
    public function rules()
    {
        return [
            /** Other rules **/
            'email' => ['required', 'email'],
        ];
    }
    /**
     * Configure the validator instance.
     *
     * @param  \Illuminate\Validation\Validator  $validator
     * @return void
     */
    public function withValidator($validator)
    {
        $validator->after(function ($validator) {
            $alreadyExists = DB::table('users')
                ->where('id', '<>', auth()->id())
                ->where('email', $this->email)
                ->exists();

            if (auth()->user()->isAdmin() && $alreadyExists) {
                $validator->errors()->add('email', 'The email address is already taken');
            }
        });
    }
}

您需要在用户模型上实现一个isAdmin()方法，以验证用户是否是管理员。

//USer model
public function isAdmin()
{
    //Determine if the user has the role of admin
    return $this->hasRole('admin');

    // or if there's a is_admin boolean column on users table

    return $this->is_admin === true;
}
