如何在 laravel 5.8 中显示自定义消息？

Question

我正在使用 laravel 5.8 版本，我有一个 api 负责注册，我创建了一个请求文件，其中包含 rules() 和 messages() 函数来显示错误消息，但它是如果任何验证失败都不会抛出任何错误消息，有人可以解释为什么会这样吗？

UserController.php

<?php

namespace App\Http\Controllers;

use App\Http\Requests\userRequest;
use App\UserSection;

class UserController extends Controller
{
    public function userRegister(userRequest $request){

        //logic of my code                    
        return response()->json($success);
    }
}

userRequest.php

<?php

namespace App\Http\Requests;

use App\Rules\CustomRule;
use Illuminate\Foundation\Http\FormRequest;

class userRequest extends FormRequest
{

    public function messages()
    {
        return [
            'first_name.required' => 'A title is required',
        ];
    }
    /**
     * 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
     */
    
    public function rules()
    {
        return [
            'first_name' => 'string|required|max:25',
            'phone_number' => 'required|integer'
        ];
    }

}

我在没有 first_name 键的情况下到达路线时遇到的错误显示 404 未找到错误

Answer 1

您可能错过了参加 form-data

的 headers 部分

Accept = application/json

Answer 2

作为laravel docs

If validation fails, a redirect response will be generated to send the user back to their previous location. The errors will also be flashed to the session so they are available for display. If the request was an AJAX request, a HTTP response with a 422 status code will be returned to the user including a JSON representation of the validation errors.

所以你需要指定你期望的响应类型，如果你使用 postman 来测试你的 api 端点你必须在请求中添加 header Accept:application/json

<?php

namespace App\Http\Controllers;

use App\Http\Requests\userRequest;
use App\UserSection;

class UserController extends Controller
{
    public function userRegister(userRequest $request){
        //logic of my code                    
        return response()->json($success);
    }
}
