Question

我有一个返回简单字符串的REST服务。当我使用WCF测试客户端时，服务返回预期值，但是当我使用浏览器访问服务时，页面显示为空。有任何想法吗？所有代码都在下面。

CUCC.svc.cs

 public class CUCC : ICUCC
{
    public string AllAtms(string serviceKey)
    {
        //return new XElement("AllAtms") ;
        return "test";
    }

    //public XElement AllOrganizationAtms(string serviceKey, int organizationId)
    //{
    //    return new XElement("AllOrganizationAtms");
    //}
}

ICUCC.cs

[ServiceContract]
public interface ICUCC
{
    [OperationContract]
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "AllAtms/{serviceKey}")]
    string AllAtms(string serviceKey);

    //[OperationContract]
    //[WebInvoke(Method = "GET",
    //    ResponseFormat = WebMessageFormat.Xml,
    //    BodyStyle = WebMessageBodyStyle.Wrapped,
    //    UriTemplate = "AllAtms/{serviceKey}/{organizationId}")]
    //XElement AllOrganizationAtms(string serviceKey, int organizationId);
}

抱歉，忘记包含我正在使用的网址。

问题在于：

  <service name="CUCC.AllAtms" behaviorConfiguration="ServiceBehaviour">
    <endpoint address="" binding="webHttpBinding" contract="CUCC.AllAtms" behaviorConfiguration="web"></endpoint>
  </service>

此服务定义声称在CUCC名称空间中有一个名为AllAtms的服务;但是没有这样的服务。当您使用svc文件的URI调用服务时，IIS会尝试查找与您正在使用的服务的实际名称相匹配的服务定义。 IIS从svc文件中获取服务的正确名称，但它找不到与正确服务名称匹配的服务配置，因此它返回HTTP 400（错误请求）。您可以使用Fiddler轻松查看此结果。

服务名称应该是实现类的名称空间限定名称，合同应该是接口的名称空间限定名称。例如：

  <service name="StackOverflow15910199.CUCC">
    <endpoint address="" binding="webHttpBinding" contract="StackOverflow15910199.ICUCC" behaviorConfiguration="web" />
  </service>

必须是与此服务关联的WCF库项目在其App.config文件中具有正确定义的服务和端点，这就是WCF测试客户端正在工作的原因。测试客户端不应该使用您发布的服务配置。

WCF Rest Service不在浏览器中返回数据
