我是c#的新手。对不起

我正在尝试创建一个WCF Rest服务，以便在web服务器上获取和放置文件。以下操作非常有效：

         [OperationContract]
    [WebInvoke(Method = "GET", BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "GetMediaFile?shopNumber={shopNumber}&fileName={fileName}")]
    Stream GetMediaFile(string shopNumber, string fileName);

所有操作都按预期工作，直到我添加以下操作

 [OperationContract]
    [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat =        WebMessageFormat.Json, UriTemplate = "PutMediaFile?shopNumber={shopNumber}&fileName={fileName}")]
    string PutMediaFile(string shopNumber, string fileName, Stream mediaFile);

我通过点击绿色箭头来安装服务，绿色箭头会启动安装服务的工具。我需要这样做，以测试它在我的IOS设备。

问题是，一旦添加POST方法，在服务安装过程中就会出现以下错误：

 "Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata"

接着是一个更深入的解释：

 "Error: Cannot obtain Metadata from http://localhost/MpiPhotoStore/PhotoStoreService.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.  For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error    URI: http://localhost/MpiPhotoStore/PhotoStoreService.svc    Metadata contains a reference that cannot be resolved: 'http://localhost/MpiPhotoStore/PhotoStoreService.svc'.    There was no endpoint listening at http://localhost/MpiPhotoStore/PhotoStoreService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.    The remote server returned an error: (404) Not Found.HTTP GET Error    URI: http://localhost/MpiPhotoStore/PhotoStoreService.svc    There was an error downloading 'http://localhost/MpiPhotoStore/PhotoStoreService.svc'.

就像我说的，我有一个2 GET操作和1个DELETE操作，这些操作都很好。

这是我的Web.Config

 <?xml version="1.0"?>
 <configuration>

 <appSettings>
 <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
 <add key="RootFilePath" value="\\OMMACDEV02VM1\Images"/>
 </appSettings>
 <system.web>
  <compilation debug="true" targetFramework="4.0" />
  </system.web>
 <system.serviceModel>
 <protocolMapping>
  <add scheme="http" binding="webHttpBinding"/>
 </protocolMapping>
 <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>
  <endpointBehaviors>
    <behavior>
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

我读过关于mex端点的文章，但我现在只看JSON。Web.Config对其他每一种方法都很有效。

救命
