Anyone who knows about webapis knows that the default WebApi methods include Get, Post, and Put. If too many other Post methods are added, they cannot be identified, and other preparations need to be added, the requested Url must contain the Controller and Action, which is inconsistent with the Restful design. Odata can solve this problem.

Configure routing Service

Builder. namespace = "ProductService"; builder. entityType <Product> (). collection. function ("MostExpensive") // Function routing. returns <double> (); builder. namespace = "ProductService"; builder. entityType <Product> (). action ("Rate") // Action route. parameter <int> ("Rating ");

When MostExpensive is requested through Get, the following error occurs:

Modify Web. config <modules runAllManagedModulesForAllRequests = "true"> </modules>

Action Request

              $.ajax({                url: "/Odata/Products(" + id + ")/ProductService.Rate",                type: "POST",                contentType: "application/json; charset=utf-8",                dataType: "JSON",                data: JSON.stringify({ Rating: 5 }),                success: function (r) {                    debugger;                },                error: function (e) {                    debugger;                }            });
