使用Vue JS进行Laravel验证

Question

i want to post ajax request using vue-resource this.$http.post request. it worked perfectly fine if i passed all validation rules but i want to get some validations if it fails. so far i keep getting 500 error if i don't fill out some input fields. it's hard for me to debug the error because it didn't appeared on the network tab.

here's what i've done so far

//my modal component
<script>
export default {
    props: ['show'],

    data() {
        return {
            input: {
                id: '',
                name: '',
                address: '',
                email: ''
            },
            errorInputs: {}
        }
    },

    methods: {
        createStudent() {
            this.$http.post('/students', this.$data.input)
                .then((response) => {
               alert('added new row!)
            }, (response) => {
                console.log(response.data);
            });
        }
      }
   }
</script>

// my controller

public function store(Request $request) {
    $validator = $this->validate($request,[
        'id' => 'required',
        'name' => 'required|unique:students',
        'email' => 'required|unique:students|email',
        'address' => 'required',
    ]);

    if($validator->passes()){
        Student::create($request->all());

        return response()->json([], 201);
    }

    $errors = json_decode($validator->errors());

    return response()->json([
        'success' => false,
        'message' => $errors
    ],422);
}

any helps and references would be appreciated. i am using laravel 5.3 and vue js 2

Answer 1

$this->validate() returns 422 error response alongside your validation errors, so you should get those errors in then() second callback (like you do now). Your vue component body should be like this:

{
    data() {
        // ...
    },
    createStudent() {
        this.$http
            .post('/students', this.input)
            .then(this.handleSuccess, this.handleError)
    },
    handleSuccess(res) {
        alert('student created')
    },
    handleError(res) {
        if (res.status === 422) {
            this.errorInputs = res.body
        } else {
            alert('Unkown error!')
        }
    }
}

Remember to add v-model="input.fieldName" properties to your inputs.

Answer 2

Remember to include your session token along with your post, unless of course you are disabling csrf tokens for that route.

Since Laravel 5.1 you can disable this in your verifytoken middleware

 <?php namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as ...

class VerifyCsrfToken extends ...    {
  protected $except = [
    'payment/*',
  ];
}
