汇总：ASP.NET Core中HttpContext获取传参数据，有哪些方式

一、原生方式：

1.POST(以ajax请求为案例，教大家用法)

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

 

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

2.GET(url传参为案例，教大家用法)

127.0.0.1/index/demo/get?num=1

 

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

二、以对象的形式接收参数（get/post通用）：

public class PageModel
    {
        public string TitleName { get; set; }//筛选标题
        public int CurrentPage { get; set; }//当前页
        public int NumCount { get; set; } //每页数量
        public long Id { get; set; } = 0;//默认id
        public string Token { get; set; } = "";//认证授权
    }

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

三、路由实现传参（get/post通用）：

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;
        }
