WCF Json GET Service: Check that the sender and receiver's EndpointAddresses agree
提问by user1418704
I've been working in .NET for a while now, but I'm new to WCF. I'm trying to create my very first WCF service using JSON. I thought I would start really, really simple and then build from there. But I have somehow managed to screw up even the most simple of services. Here's what I've got so far.
我已经在 .NET 中工作了一段时间，但我是 WCF 的新手。我正在尝试使用 JSON 创建我的第一个 WCF 服务。我想我会从非常非常简单的开始，然后从那里开始构建。但我以某种方式设法搞砸了即使是最简单的服务。这是我到目前为止所得到的。
Web.Config:
网络配置：
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="MarathonInfo.MarathonInfoService">
<endpoint address="http://localhost:10298/MarathonInfoService.svc" binding="webHttpBinding" contract="MarathonInfo.IMarathonInfo" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above 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>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Then, in the service file:
然后，在服务文件中：
namespace MarathonInfo
{
public class MarathonInfoService : IMarathonInfo
{
public String GetData()
{
return "Hello World";
}
}
}
And in the interface:
并在界面中：
namespace MarathonInfo
{
[ServiceContract]
public interface IMarathonInfo
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/GetData", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
String GetData();
}
}
So, when I go to this url:
所以，当我去这个网址时：
http://localhost:10298/MarathonInfoService.svc/GetData
I get this error:
我收到此错误：
The message with To 'http://localhost:10298/MarathonInfoService.svc/GetData' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree.
由于 EndpointDispatcher 处的 AddressFilter 不匹配，无法在接收方处理带有 To 'http://localhost:10298/MarathonInfoService.svc/GetData' 的消息。检查发送方和接收方的 EndpointAddresses 是否一致。
I am able to execute the service just fine through Visual Studio in debug mode. But in the browser, I only get that error.
我能够在调试模式下通过 Visual Studio 很好地执行服务。但是在浏览器中，我只会收到那个错误。
What am I doing wrong?
我究竟做错了什么？
Thanks!
谢谢！

If you want to create a WCF WebHTTP Endpoint (i.e., one which returns JSON, and uses the [WebGet] / [WebInvoke] attributes), the endpoint needs to have the <webHttp/>behavior associated with it.
如果要创建 WCF WebHTTP 端点（即，返回 JSON 并使用 [WebGet] / [WebInvoke] 属性的端点），端点需要具有<webHttp/>与其关联的行为。
<system.serviceModel>
<services>
<service name="MarathonInfo.MarathonInfoService">
<endpoint address="http://localhost:10298/MarathonInfoService.svc"
binding="webHttpBinding"
contract="MarathonInfo.IMarathonInfo"
behaviorConfiguration="Web"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="Web">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>
