**Startup 配置**
>ConfigureServices 中 services.AddMvc后面追加AddJsonOptions.
代码如下：
```
services.AddMvc(options =>
{
options.Filters.Add<ActionFilterAttributeLogin>();
})
.AddJsonOptions(options =>
{
options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
});
```
**Controller Action只能返回两种**
><P style="color:red;">注意：不能使用，Newtonsoft.Json.JsonConvert.SerializeObject(data);序列化否则时间还是会出现T问题。</p>
1.
```
[HttpPost]
public async Task<JsonResult> SearchPlanForId(int Id)
{
var model = await MaintainBLL.GetPlanForWorkOrder(Id);
return Json(model);
}
```
2.
```
[HttpPost]
public async Task<PlanOrderShowModel> SearchPlanForId(int Id)
{
var model = await MaintainBLL.GetPlanForWorkOrder(Id);
return model;
}
```
