Question

我在c＃上完全是新手。的 SORRY

我正在尝试创建一个WCF Rest服务来获取和放置Web服务器上的文件。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);

在我添加以下操作之前，所有内容都按预期工作

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

我正在安装该服务，方法是单击启动安装该服务的工具的绿色箭头。我需要这样做才能从我的IOS设备上进行测试。

问题是，一旦我添加POST方法，我在服务安装期间收到以下错误：

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

然后是更深入的解释：

 "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.

就像我说的，我有一个2 GET操作和1个DELETE操作都可以正常工作。

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" />

我已经阅读了关于mex端点但我现在真的只关注JSON。 Web.Config适用于其他所有方法。

HELP !!!!!!!!!!!!!!
