在mvc中的post中获取第二个参数null [英] getting second parameter null in post in mvc

问题描述

我在控制器中使用httppost动作并使用角度js进行调用。但是第二个参数的getiing始终为null。



我的操作方法

 [HttpPost] 
 public JsonResult Services_PageSize（string PageSize，string ServiceCategory_Id）
 {
 int n; 
 bool isNumericPageSize = int.TryParse（PageSize，out n）; 
 bool isNumericServiceCategory_Id = int.TryParse（ServiceCategory_Id，out n）; 
返回新的JsonResult {Data = new {Services = _Services，Status = isNumericPageSize}，}; 
} 
 

和我的角度js控制器是

 this.getServices = function（pageSize，ServiceCategoryId）{
 return $ http（{
方法：post，
 url：/ Home / Services_PageSize？pageSize =+ pageSize +& ServiceCategoryId =+ ServiceCategoryId 
 
}）; 
 

解决方案

http（{
method：post，
url：/ Home / Services_PageSize？pageSize =+ pageSize +& ServiceCategoryId =+ ServiceCategoryId

}）;

你可以试试这个，

  this  .getServices =  function （pageSize，ServiceCategoryId）{
  var  d = {
 PageSize：pageSize，
 ServiceCategory_Id：ServiceCategoryId 
}; 
  return  

http（{
method： post，
url： / Home / Services_PageSize，
数据：d
}）;
}

您的变量名称与服务器方法的变量不匹配，我希望它有所帮助。

I am using httppost action in controller and calling using angular js. but getiing second parameter always null.

My action method

[HttpPost]
public JsonResult Services_PageSize(string PageSize, string ServiceCategory_Id)
{
    int n;
    bool isNumericPageSize = int.TryParse(PageSize, out n);
    bool isNumericServiceCategory_Id = int.TryParse(ServiceCategory_Id, out n);
return new JsonResult { Data = new { Services = _Services, Status =        isNumericPageSize }, };
}

and my angular js controller is

 this.getServices = function (pageSize, ServiceCategoryId) {
   return $http({
    method: "post",
    url: "/Home/Services_PageSize?pageSize=" + pageSize + "& ServiceCategoryId=" + ServiceCategoryId

});

解决方案

http({ method: "post", url: "/Home/Services_PageSize?pageSize=" + pageSize + "& ServiceCategoryId=" + ServiceCategoryId });

You can try this,

this.getServices = function(pageSize, ServiceCategoryId) {
    var d = {
        PageSize: pageSize,
        ServiceCategory_Id: ServiceCategoryId
    };
    return

http({ method: "post", url: "/Home/Services_PageSize", data: d }); }

Your variable name is not matching with the variable of the server method, I hope it helps.
