wcf - 如何通过浏览器(火狐)调用WCF服务？

Question

我只是想知道如何通过浏览器(Firefox)调用 WCF 服务？

我的 WCF 服务如下所示:

http://localhost:4249/TestService.svc

我试过这个:

[ServiceContract]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "/GetAllPersons", ResponseFormat = WebMessageFormat.Xml)]
    List<Person> GetAllPersons();


public class TestService : ITestService
{
    public List<Person> GetAllPersons()
    {
        return Employees.CreateEmployees();
    }

我在浏览器的地址行中试过这个:

http://localhost:4249/TestService/GetAllPersons

但是，我有以下错误:

Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /TestService/GetAllPersons

我做错了什么？

这是我的 web.config 文件，你可以看看:

Answer 1

除了上面评论中提到的工厂更改之外，您还需要在 web.config 中启用 webHttpBinding。将此用作模板，从现有的 web.config 中复制契约(Contract)和名称详细信息:

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"  multipleSiteBindingsEnabled="true" />
<bindings>
  <webHttpBinding>
    <binding name="WHB" crossDomainScriptAccessEnabled="true">
      <security mode="None" />
    </binding>
  </webHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="AllowGet">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="AllowGet" name="">
    <endpoint address="" binding="webHttpBinding"
      bindingConfiguration="WHB" contract="" />
  </service>
</services>
