Summary: ASP.NET Core obtain pass in HttpContext parameter data, there are ways in which

A native mode:

1.POST (with ajax request as an example, we teach usage)

            $.ajax({
                                type: "post",
                  dataType: "json",
                  cache: false,
                  data: {
                      method: "add"
                  },
            url: "../demo/post",
                  async: true,
                  success: function (data) {
                                    if (data.isOK) {
                                        alert("成功" ); 
                                    } 
                                    The else { 
                                        Alert (" failure "); 
                                    } 
                                } 
                            });

 

IFormCollection form = HttpContext.Request.Form;
string method = form["method"];    

2.GET (url mass participation as a case study, teach you use)

127.0.0.1/index/demo/get?num=1

 

IQueryCollection queryParameters = HttpContext.Request.Query;
string num = queryParameters["num"];

Second, the parameters received in the form of the object (get / post General):

public  class PageModel 
    { 
        public  String TITLENAME { GET ; the SET ;} // Filter title 
        public  int CurrentPage { GET ; the SET ;} // this page 
        public  int NumCount { GET ; the SET ;} // page number of 
        public  Long Id { GET ; SET ;} = 0 ; // default ID 
        public  String the Token { GET ; SET ;} ="" ; // authentication and authorization 
    }

public IActionResult UserList(PageModel pageModel)
        {
            return View(pageModel);
        }

Third, the route to achieve mass participation (get / post General):

127.0.0.1/Index/MenuDelAsync/1

 

public async Task<string> MenuDelAsync(long id)
        {
            string jsonResult = "[]";
            bool b = false;
            b = await articleService.DelArticleTypeAsync(id);
            if (b)
                jsonResult = CommonHelper.NewGetJsonResult(1, "删除成功");
            else
                jsonResult = CommonHelper.NewGetJsonResult(-1, "删除失败");
            return jsonResult;
        }
