Asp.net mvc 通过 httpClient 连接到 webApi

Question

我有 mvc 应用程序和 webApi 应用程序。我需要通过 webApi 登录 asp.net mvc。当我使用这种方法时：

public static string GetToken(LoginModelView login)
        {
            var pairs = new List<KeyValuePair<string, string>>
                        {
                            new KeyValuePair<string, string>( "grant_type", "password" ),
                            new KeyValuePair<string, string>( "username", login.Login ),
                            new KeyValuePair<string, string> ( "Password", login.Password )
                        };
            var content = new FormUrlEncodedContent(pairs);
            using (var client = new HttpClient())
            {
                var response =
                    client.PostAsync(URL + "/Token", content).Result;
                var responseJson = response.Content.ReadAsStringAsync().Result;
                var dictionaryToken = JsonConvert.DeserializeObject<Dictionary<string,string>>(responseJson);
                string token = dictionaryToken["access_token"];
                return token;
            }
        }

我的 mvc 没有从视图中绑定模型。动作方法

[HttpGet]
        public ActionResult SignIn()
        {
            var login = new LoginModelView();
            return View("SignIn",login);
        }

        [HttpPost]
        public ActionResult SignIn(LoginModelView login)
        {
            string token = DirService.GetToken(login);

            Session["token"] = token;

            return RedirectToAction("success");
        }

是模特

public class LoginModelView
    {
        public string Login { get; set; }

        public string Password { get; set; }
    }

这是我的观点

@model AdminTool.Models.LoginModelView
    @using (Html.BeginForm())
    {
        @Html.AntiForgeryToken()

        <div class="form-horizontal">
            <h4>LoginModelView</h4>
            <hr />
            @Html.ValidationSummary(true, "", new { @class = "text-danger" })
            <div class="form-group">
                @Html.LabelFor(model => model.Login, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.Login, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Login, "", new { @class = "text-danger" })
                </div>
            </div>

            <div class="form-group">
                @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })
                </div>
            </div>

            <div class="form-group">
                <div class="col-md-offset-2 col-md-10">
                    <input type="submit" value="Login" class="btn btn-default" />
                </div>
            </div>
        </div>
    }

当我不使用那个方法时，一切正常。相同的代码在另一个应用程序中工作。请有人可以帮助我..

Answer 1

我认为您是从数据发布到获取方法 (GetToken)。

Answer 2

我注意到 LoginModelView class 中有 Login 属性并且您在 controller.I 中创建相同的对象名称 LoginModelView login 更改该代码及其对我的工作。

型号：-

           [HttpGet]
            public ActionResult SignIn()
            {
                var loginModelView = new LoginModelView();
                return View("SignIn", loginModelView);
            }

            [HttpPost]
            public ActionResult SignIn(LoginModelView loginModelView)
            {
                string token = DirService.GetToken(loginModelView);

                Session["token"] = token;

                return RedirectToAction("success");
            }

希望它的工作!!!

编码愉快!!
