使本地Web API调用本地Web窗体应用程序 [英] make local web api call from local web forms app

问题描述

我想知道，如果它可能使这一呼吁：

I want to know if its possible to make this call:

jQuery.ajax({
            type: "POST",
            url: "http://localhost:5832/api/Login",
            data: "{username: user1, password:'123456'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json", 
            success: function (data) {
                alert(data.d);
            }
        });

这基本上是调用此Web API控制器：

Which is basically call to this web api controller:

public class LoginController : ApiController
    {
        [System.Web.Http.AcceptVerbs("POST")]
        public HttpResponseMessage Post(string username, string password)
        {
            string authenticationToken = "";
            Helpers hpl = new Helpers();
            authenticationToken = hpl.LoginUser(username, password);
            int userId = 0;
            if (Int32.TryParse(authenticationToken, out userId))
            {
                bool isValidGame = false;
                ssqGame game = db.ssqGames.Where(s => s.userId == userId).FirstOrDefault();
                if (game.ssqGameId != 0)
                {
                    ssqLogin login = db.ssqLogins.FirstOrDefault(s => s.ssqGameId == game.ssqGameId);
                    if (login != null)
                    {
                        return Request.CreateResponse(HttpStatusCode.OK, "Token: " + login.authorizationToken, new JsonMediaTypeFormatter(), "application/json");
                    }
                    else
                    {
                        ssqLogin loginNew = new ssqLogin();
                        loginNew.ssqGameId = game.ssqGameId;
                        loginNew.login = DateTime.Now;
                        loginNew.activeState = 1;
                        loginNew.authorizationToken = hpl.RandomString(30);
                        db.ssqLogins.Add(loginNew);
                        db.SaveChanges();
                    }
                }
            }

            return Request.CreateResponse(HttpStatusCode.OK, authenticationToken);
        }
    }

jQuery的AJAX调用是从在不同端口上运行的其他本地网络形式的项目：的http：//本地主机：15528 /测试。我想知道，如果它能够拨打电话，如这一个，因为我不能在这个时候触发功能，在萤火看到此错误：的

The jquery ajax call is from another local web forms project which is running on a different port:

推荐答案

是的，绝对有可能，你只要启用您的Web API CORS，看看这篇文章：

Yes, definitely possible, you just enable CORS for your web api, take a look this article:
