简单的REST WCF服务示例代码-找不到端点

Question

我在第5章-RESTful .Net中尝试了一个示例，但由于某种原因而无法使它正常工作（接收404-未找到）。

using System;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.ServiceModel.Web;

[ServiceContract]
public class RestService
{
    [OperationContract]
    [WebGet(UriTemplate = "Hosting")]
    public void Hosting()
    {
        Console.WriteLine("RestService::Hosting()");
        WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK;
    }

    static void Main(string[] args)
    {
        var host = new ServiceHost(typeof(RestService));
        var endpoint = host.AddServiceEndpoint(typeof(RestService), new WebHttpBinding(), "http://localhost:8080/Hosting");
        endpoint.Behaviors.Add(new WebHttpBehavior());

        host.Open();
        Console.ReadKey();
    }
}

如果我按如下方式使用WebServiceHost，它将正常工作（返回状态码OK）

    static void Main(string[] args)
    {
        var host = new WebServiceHost(typeof(RestService), new Uri("http://localhost:8080"));
        host.Open();
        Console.ReadKey();
    }

因此，问题是如何使其与ServiceHost一起使用（如果可能，不使用任何配置文件等）？

WebServiceHost为您创建一个EndPoint，如果继续使用它，不会有任何问题。 请参阅此链接以获取更多详细信息...

但是您还可以在服务配置中添加以下配置以使用ServiceHost ，我已经给出了一个示例，您可以对其进行更改以反映您的服务类。

<system.serviceModel>
        <services>
            <service name="YourService.DateTimeService" behaviorConfiguration="customBehavior">
                <endpoint address="Basic" binding="basicHttpBinding" contract="DifferentBindings.IDateTime">
                    <identity>
                        <dns value="localhost" />
                    </identity>
                </endpoint>             
                <endpoint address="Web" binding="webHttpBinding" contract="DifferentBindings.IDateTime" behaviorConfiguration="webHttpBehavior">
                    <identity>
                        <dns value="localhost"/>
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />                
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:8731/DifferentBindings/DateTimeService/" />                      
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior>
                    <!-- To avoid disclosing metadata information, 
          set the value below to false before deployment -->
                    <serviceMetadata httpGetEnabled="True"/>
                    <!-- To receive exception details in faults for debugging purposes, 
          set the value below to true.  Set to false before deployment 
          to avoid disclosing exception information -->
                    <serviceDebug includeExceptionDetailInFaults="False" />
                </behavior>             
            </serviceBehaviors>
            <endpointBehaviors>
                <behavior name="webHttpBehavior">
                    <webHttp/>
                </behavior>
            </endpointBehaviors>
        </behaviors>
    </system.serviceModel>

Answer 2

因此，我很好奇WCF的复杂性。 试了一下。 努力前进。

我使用本教程创建了一个简单的服务，该服务具有一个doWork方法，该方法需要一个字符串并返回问候语。

问候：

[DataContract]
public class Greeting
{
    [DataMember]
    public string Str { get; set; }
}

服务合同：

[OperationContract]
[WebInvoke(Method = "ResponseFormat = WebMessageFormat.BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "sayHello/{name}/")]
Greeting DoWork(string name);

Svc Impl：

public class GreetingService : IGreetingService
{
    public Greeting DoWork(string name)
    {
        return new Greeting {Str = string.Format("Hello {0}", name)};
    }
}

然后，您可以先通过以下方式对其进行测试：

• 右键单击Visual Studio中的svc文件>在浏览器中查看
• 在网址中添加“ sayHello / test”
• 在浏览器中查看问候语

消费者可以使用$ http或$ resource服务在AngularJS中实现

<!DOCTYPE html>
<html ng-app="restTest">
<head>
    <title></title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.27/angular.min.js"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.27/angular-resource.min.js"></script>
    <script language="javascript">
        // set up the app
        var app = angular.module('restTest', ['ngResource']);

        // create a controller
        app.controller('RestTestCtrl', function ($scope, $http, $resource) {
            // initial greeting
            $scope.greeting = "Not greeted yet";

            // say hello, consuming the svc using $http
            $scope.sayHelloHttp = function () {
                var url = "http://localhost:7507/GreetingService.svc/sayHello/" + $scope.inName + "/";
                $http.get(url).
                    success(function(data) {
                        $scope.greeting = data.Str;
                    });
            }

            // say hello, consuming the svc using $resource
            $scope.sayHelloRest = function () {
                var GreetingSvc = $resource("http://localhost:7507/GreetingService.svc/sayHello/:name");
                GreetingSvc.get({ name: $scope.inName }, function(data) {
                    $scope.greeting = data.Str;
                });
            }
        });
    </script>
</head>
    <body ng-controller="RestTestCtrl">
        <!-- bind the value of this input to the scope -->
        <input type="text" ng-model="inName"/>
        <button ng-click="sayHelloHttp()">$http</button>
        <button ng-click="sayHelloRest()">$resource</button>
        <!-- bind the greeting property -->
        <div>{{greeting}}</div>
    </body>
</html>

我想以上所有内容都可以表达得更高级，但是它应该为您提供一个基本且可行的示例来开始。
