如何编写JSON Laravel的验证规则? [英] How to write validation rule for JSON laravel?

问题描述

有一个我要验证的JSON对象:

There is JSON object that I want to validate:

[{
  "id": 1,
  "settings": {
    "GRSYSEM": 1
  }
},
{
  "id": 2,
  "settings": {
    "GRSYSEM": 1
  }
},
{
  "id": 3,
  "settings": {
    "GRSYSEM": 1
  }
}
]

如何在Laravel中编写验证规则?

How to write validation rule in Laravel?

我尝试了以下规则:

$validator = Validator::make($request->all(), [
    'id' => 'required|array',
    'id.*' => 'required',
    'settings.*.GRSYSEM' => 'required'
]);

推荐答案

您快到了，只需将通配符*放在第一位即可.

You are almost there, simply put the wildcard * first:

$validator = Validator::make($request->all(), [
    '*.id' => 'required',
    '*.settings.GRSYSEM' => 'required'
]);

它的字面意思是:对于数组中的每个元素，我期望一个id和一个设置GRSYSEM.

It literally says: For each element in the array, I expect an id and a setting GRSYSEM.

您还可以通过使用一些技巧来确保它是一个数组:

You could also ensure it's an array by using a little hack:

$data = ['input' => $request->all()];

$validator = Validator::make($data, [
    'input' => 'required|array',
    'input.*.id' => 'required',
    'input.*.settings.GRSYSEM' => 'required'
]);
