Question

我是WCF新手并且在WCF中创建了一个rest api服务，我正在关注this tutorial。

这是我的合同代码。

[ServiceContract]
public interface IPayrollRest
{


    [OperationContract]
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "GET",  ResponseFormat = WebMessageFormat.Xml, UriTemplate = "xml/{EmployeeId}")]
    string XMLData(string EmployeeId);

    [OperationContract]
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "GET",  ResponseFormat = WebMessageFormat.Json, UriTemplate = "json/{EmployeeId}")]
    string JSONData(string EmployeeId);



}

并执行本合同如下

public string XMLData(string EmployeeId )
{
    return "Your EmployeeId " + EmployeeId;
}

public string JSONData(string EmployeeId)
{
    return "Your EmployeeId " + EmployeeId;
}

我对此服务的配置如下

<system.serviceModel>
        <services>
            <service behaviorConfiguration="PayrollService.Service1Behavior" name="PayrollService.Service1">
                <endpoint address="" binding="wsHttpBinding" contract="PayrollService.IService1">
                    <identity>
                        <dns value="localhost"/>
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
            </service>
            <service behaviorConfiguration="PayrollService.PayrollRestBehavior" name="PayrollService.PayrollRest">
                <endpoint address="" binding="wsHttpBinding" contract="PayrollService.IPayrollRest">
                    <identity>
                        <dns value="localhost"/>
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="PayrollService.Service1Behavior">
                    <serviceMetadata httpGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="false"/>
                </behavior>
                <behavior name="PayrollService.PayrollRestBehavior">

                    <serviceMetadata httpGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="false"/>

                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>

当我在网络浏览器中运行我的代码时

**http://localhost:56140/PayrollRest.svc/xml/123**

浏览器中没有任何内容。

您需要使用webHttpBinding，如文章中所示。我已使用以下配置对其进行了测试：

<system.serviceModel>
    <services>
        <service name="PayrollService.Service1Behavior"
                 behaviorConfiguration="ServiceBehaviour">
            <endpoint address="" binding="webHttpBinding"
                      contract="PayrollService.IPayrollRest"
                      behaviorConfiguration="web"/>
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ServiceBehaviour">
                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="false"/>
            </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
            <behavior name="web">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
</system.serviceModel>

WCF rest api在浏览器中没有显示任何内容
