使用邮递员将GUID列表发布到MVC 5控制器 [英] Posting a List of GUIDs to a MVC 5 Controller with Postman
问题描述
我正在尝试制作一个控制器方法:
public String CreateGasolineBlend(List< Guid> enumerableTransferIDs)
{
//详细信息
}
接受GUID列表。但是,当我使用邮递员时,列表始终为空。
我尝试使用本文来查找如何格式化请求:
I'm attempting to make a controller method:
public String CreateGasolineBlend(List<Guid> enumerableTransferIDs)
{
//Details
}
Accept a list of GUIDs. However, the list is always null when I'm using postman.
I tried using this article to find out how to format the request:
Is it possible to send an array with the Postman Chrome extension?
But I'm unsure if MVC even is capable of accepting a List of objects using a Post Method, or if perhaps I am incorrectly formatting the POST request in Postman.
(I am using what the previous stack overflow question states, arr[0], arr[1] or arr[], arr[] with Guids as values.)
Is my problem with the way I'm receiving the values in the controller, or is it a problem with how I'm using Postman?
MVC is capable of accepting a list objects and map it to the action method parameter.
You need to make sure you are using the correct Content-Type
header value when send the data. "application/json"
should work.
I just updated your action method to return the posted data along with the item count in a json structure to verify this.
[HttpPost]
public ActionResult CreateGasolineBlend(List<Guid> enumerableTransferIDs)
{
return Json(new { ItemCount= enumerableTransferIDs.Count(),
Items= enumerableTransferIDs});
}
You can see the response came back with the data we posted.
