如何在 Laravel 中查看 API 的验证消息？

Question

我正在使用 Laravel 8 并致力于 API 的开发。我已经创建了用于表单验证的请求类，但是当移动开发人员点击 API 验证消息时，未按要求显示。这是我的控制器方法：

 public function store(InvoiceStoreRequest $request)
{
    try {
        return $this->responseWithSuccess(true,'Invoice Data',
               $this->invoiceInterface->store($request), Response::HTTP_OK);
    }catch (\Exception $exception){
        return $this->responseWithError($exception->getMessage(),Response::HTTP_OK);
    }
}

这里我使用InvoiceStoreRequest类来验证表单。代码InvoiceStoreRequest如下：

public function rules()
{
    return [
        'id' => ['required', 'string'],
        'invoice_date' => ['required', 'date'],
        'reference_number' => ['required'],
        'vendor_id' => ['required'],
        'invoice_net_total' => ['required','regex:/^\d*(\.\d{1,2})?$/'],
        'invoice_tax_total' => ['required', 'regex:/^\d*(\.\d{1,2})?$/'],
        'invoice_gross_total' => ['required', 'regex:/^\d*(\.\d{1,2})?$/'],
        'item_count' => ['required', 'numeric'],
        'invoice_type' => ['required','regex:(order|refund)'],
        'provider' => ['required'],
        'detail_url' => ['required'],
        'invoice_photo_url' => ['required'],
    ];
}

以及显示自定义消息，

public function messages()
{
    return [
        'invoice_type.regex' => 'The invoice type format is invalid. Invoice Type should be [order,refund]',
        'invoice_net_total.regex' => 'Invoice Net must be Decimal or Numeric value.',
        'invoice_tax_total.regex' => 'Invoice Tex must be Decimal or Numeric value.',
        'invoice_gross_total.regex' => 'Invoice Gross must be Decimal or Numeric value.',
    ];
}

它在邮递员上工作正常，但是当移动开发人员点击 API 时，他会收到422 Unprocessable Entity错误，但不会显示错误消息。我想显示错误消息。
我该如何解决这个问题？

Answer 1

你应该添加

Accept:application/json

调用 api 时添加到您的请求标头

例如：

Answer 2

尝试这样的事情：

$validator = Validator::make(request()->all(), [
    'name' => 'required',
    // ... Rules 
]);

if ($validator->fails()) {
    return response()->json([
        'errors' => $validator->errors(),
        'status' => Response::HTTP_BAD_REQUEST,
    ], Response::HTTP_BAD_REQUEST);
}

MODEL::create($validator->validated());

return response()->json([
    'data' => [],
    'status' => Response::HTTP_CREATED,
], Response::HTTP_CREATED);
