Netcore，JSON參數始終爲空

Question

我不知道我在做什麼錯或改變了什麼。 我試圖發送JSON參數的MVC控制器磊1.1

MVC控制器：

[HttpPost] 
public JsonResult Test1(DepartmentDTO departmentDto, int testId) 
{ 
    return Json(departmentDto); 
} 
public partial class DepartmentDTO 
{ 
    public int DepartmentID { get; set; } 
    public string Description{ get; set; } 
} 

的Javascript POST：

var req = { 
    method: 'POST', 
    url: "/Department/Test1", 
    headers: { 
     'Content-Type': 'application/json;charset=utf-8' 
    }, 
    data: JSON.stringify({ 
     "departmentDto": { "DepartmentID": 1, "Description": "TEST" }, 
     "testId": 1 
    }), 
}; 
var promise = $http(req).then(function successCallback(response) { 
    if (response.data.departmentID == 0) { 
     alert("Wrong") 
    } 
    return response.data 
}, function errorCallback(response) { 
    return { success: false, message: response.data }; 
}); 

所有參數都總是空：departmentDto & testId 謝謝你的幫助。

Answer 1

[FromBody]只能使用一次。身體流只是向前。

建議：

[Route("Department")] 
public class DepartmentController : Controller { 
    [HttpPost("Test1/{testId:int}")] //Matches POST Department/Test1/1 
    public IActionResult Test1(int testId, [FromBody]DepartmentDTO departmentDto) { 
     return Json(departmentDto); 
    } 
} 

而且修改請求

var req = { 
    method: 'POST', 
    url: "/Department/Test1/1", 
    headers: { 
     'Content-Type': 'application/json;charset=utf-8' 
    }, 
    data: JSON.stringify({ "DepartmentID": 1, "Description": "TEST" }), 
}; 

如果不是這樣，建立一個滿足什麼是從客戶端字符串化並具有作爲單一操作參數標記[FromBody]一個新的對象模型
