Laravel Response::json() with numeric check
提问by harryg
When performing an eloquent query on a model (using the MySQL driver) which has some numeric fields and then return a json response of the results, the json appears to pass numeric values as strings rather than numbers.
当对具有一些数字字段的模型（使用 MySQL 驱动程序）执行 eloquent 查询，然后返回结果的 json 响应时，json 似乎将数字值作为字符串而不是数字传递。
E.g.
例如
$properties = Model::find(6);
return Response::json($properties);
Returns something like:
返回类似：
{
"name": "A nice item",
"value": "160806.32"
}
When it should return:
什么时候应该返回：
{
"name": "A nice item",
"value": 160806.32
}
In normal php you can use the JSON_NUMERIC_CHECKto solve this but there appears to be no such option for the Response::json()method. How can I ensure numeric fields are returned as numbers rather than strings?
在普通的 php 中，您可以使用JSON_NUMERIC_CHECK来解决这个问题，但该Response::json()方法似乎没有这样的选项。如何确保数字字段作为数字而不是字符串返回？

You can actually pass that option over. If we take a look at the source code for the JsonResponse classyou can pass json_encode options as the last parameter.
您实际上可以传递该选项。如果我们查看JsonResponse 类的源代码，您可以将 json_encode 选项作为最后一个参数传递。
It would look something like this
它看起来像这样
return Response::json($properties, 200, [], JSON_NUMERIC_CHECK);
Alternativelyyou could do this:
或者你可以这样做：
return Response::make(
$properties->toJson(JSON_NUMERIC_CHECK),
200,
['Content-Type' => 'application/json']
);
Note: if $propertiesis not an Elequoent model then it must at least implement the JsonableInterface
注意：如果$properties不是 Elequoent 模型，那么它至少必须实现JsonableInterface
as well as:
以及：
return Response::make(
json_encode($properties->toArray(), JSON_NUMERIC_CHECK),
200,
['Content-Type' => 'application/json']
);
The toJson()method in Eloquent just wraps json_encode()and passes it the array of your model. I'd recommend using one of the first two options.
该的toJSON（）雄辩方法只是包装json_encode()并将其传递模型的数组。我建议使用前两个选项之一。

Use method setEncodingOptionsof JsonResponse:
使用方法setEncodingOptions的JsonResponse：
return response()->json($properties)->setEncodingOptions(JSON_NUMERIC_CHECK);
