Question

在模型目录中，我有这个简单的模型：

 {
    // PUT: /User/Edit
    [HttpPut]
    public JsonResult Edit(int id, User user)
    {
        System.Diagnostics.Debug.WriteLine("Put request is working"); //не выполняется
        return Json("Response from Edit");
    }
}

在处理请求的文件夹控制器中，我有：

HttpPut

在文件Index.cshtml ajax代码中，它将/*PUT*/ $.ajax({ url: '/User/Edit', dataType: "json", type: "PUT", contentType: 'application/json; charset=utf-8', data: JSON.stringify({ id: 100, user: { name: 'Dmitry', email: 'dmitry@gmail.com' } }), async: true, processData: false, cache: false, success: function (data) { alert(data); //this message does NOT work }, error: function (xhr) { alert('error'); //This message shows } });请求发送到控制器

POST

我应该添加什么？使用JSON的$query = DB::table("fees9_items AS t1") ->select(array("t1.id", "i.item_description AS name", DB::raw("SUM(t1.amount) as total"), "u.name AS unit" ) ->leftJoin("items AS i", "i.id", "=", "t1.item_id") ->leftJoin("mesure_units AS u", "u.id", "=", "i.unit") ->leftJoin("fees9 AS f", "f.id", "=", "t1.fees9_id") ->where("date", ">=", "2016-01-01") ->where(function($query){ $query->where("f.field1", "=", 1) ->orWhere("f.field2", "=", 2) ->orWhere("f.other", "=", 1) ) ->groupBy("i.id") ->get();请求使用JSON，效果很好，问题仅在于Put请求

id参数将从URL绑定，也不需要它，因为您可以将其直接包含在User类中，因此请将其设为：

   /*PUT*/
          $.ajax({
              url: '/User/Edit/100',
              dataType: "json",
              type: "PUT",
              contentType: 'application/json; charset=utf-8',
              data: JSON.stringify({  name: 'Dmitry', email: 'dmitry@gmail.com' }),
              async: true,
              processData: false,
              cache: false,
              success: function (data) {
                  alert(data); //this message does NOT work
              },
              error: function (xhr) {
                  alert('error');   //This message shows 
              }
      });

或者你可以这样做

  /*PUT*/
          $.ajax({
              url: '/User/Edit',
              dataType: "json",
              type: "PUT",
              contentType: 'application/json; charset=utf-8',
              data: JSON.stringify({id:100,  name: 'Dmitry', email: 'dmitry@gmail.com' }),
              async: true,
              processData: false,
              cache: false,
              success: function (data) {
                  alert(data); //this message does NOT work
              },
              error: function (xhr) {
                  alert('error');   //This message shows 
              }
      });

控制器：

 // PUT: /User/Edit
    [HttpPut]
    public JsonResult Edit(User user)
    {
        System.Diagnostics.Debug.WriteLine("Put request is working"); //не выполняется
        return Json("Response from Edit");
    }

我在ASP.NET MVC应用程序中使用ajax向控制器发送HttpPut请求时出错
