在asp.net mvc 4应用程序中使用Restful WCF服务

I'm totally new with asp.net mvc. I'm having trouble consuming rest web service in asp.net mvc4 app.

我是asp.net mvc的新手。我在asp.net mvc4应用程序中使用休息Web服务时遇到问题。

This is the interface of the service:

这是服务的接口:

[ServiceContract]
public interface IService1
{
    [OperationContract]
    [WebInvoke(Method = "POST", UriTemplate = "GetRuleDetail/{id}")]
    string GetRuleDetail(string id);
}

In my mvc app I've added my service as service reference "ServiceReference1"

在我的mvc应用程序中,我添加了我的服务作为服务参考“ServiceReference1”

Then I've created a controller:

然后我创建了一个控制器:

    public ActionResult Index()
    {
        string strjson = Request["Json"].ToString();
        //string strjson = "input={\"name\": \"obj1\",\"x\": 11,\"y\":20,\"obj\":{\"testKey\":\"val\",},\"tab\":[1 , 2, 46]}";
        ServiceReference1.Service1Client obj = new ServiceReference1.Service1Client();
        return View(obj.GetRuleDetail(strjson));
    }

The string strjson, I want to pass it from the view which has the following code:

字符串strjson,我想从具有以下代码的视图中传递它:

@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";} <h2>Index</h2> <section class="contact">
<header>
    <h3>Enter your JSON string</h3>
</header>
<p>
    <ol>
        <li>
            @Html.Label("Json")
            @Html.TextBox("txtJson")
        </li>
    </ol>
</p>
<p>
    <button>Test</button>
</p>

Am I missing something? Cz strjson is always null and the Index() method is executed before I enter my jsonstring in the textbox. How can I fix that plz

我错过了什么吗? Cz strjson始终为null,并且在我在文本框中输入jsonstring之前执行了Index()方法。我怎么能解决这个问题

This is not right approach first you need to render a view than you will post it to server along with id which will then be passed to service.You need to create a model which will be binded to view.

这不是正确的方法首先你需要渲染一个视图,而不是将它与id一起发布到服务器,然后将其传递给service.You需要创建一个将被绑定以查看的模型。

First render view

首先渲染视图

public ActionResult Index()
{

    return View();//Tihs will simply return view
}

This is model class by which view will be binded

这是视图将被绑定的模型类

public class JsonData
{
    public string Id { get; set; }
}

This will be your view

这将是你的看法

 @model JsonData

@using (Html.BeginForm("GetServiceData", "ControllerName", FormMethod.Post))
{
        @Html.Label("Json")
        @Html.TextBoxFor(m=>m.Id)
        <input type="submit" value="Submit" />

}

Now when you will post this view it will go to controller along with data in textbox

现在,当您发布此视图时,它将与文本框中的数据一起转到控制器

[HttpPost]
public ActionResult GetServiceData(JsonData model)
{
    ServiceReference1.Service1Client obj = new ServiceReference1.Service1Client();
    return View(obj.GetRuleDetail(model.Id));//Tihs will simply return view
}
