C# 在Azure中将文件从Android上载到WCF

我正试图将一个文件从android上传到azure，这让我抓狂。我认为这是设置中的一些东西，因为我已经确认了在IIS和android中工作的代码。现在我可以访问c#中的方法，但我的流在服务器上是空的。在安卓系统中，我得到一个415错误“类型不匹配”。非常感谢您的帮助

这是我的c#测试客户端：

            ServiceReference1.PostImage2Request r = new ServiceReference1.PostImage2Request();
            MemoryStream memStream = new MemoryStream();                 
            using (FileStream fileStream = File.OpenRead("C:\\crap.png"))
            {
                memStream.SetLength(fileStream.Length);
                fileStream.Read(memStream.GetBuffer(), 0, (int)fileStream.Length);
            }
            r.image = memStream;
            ServiceReference1.RestServiceImplClient c = new ServiceReference1.RestServiceImplClient();
            ServiceReference1.PostImage2Response p = c.PostImage2(r);

这是我的客户端配置：

 <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IRestServiceImpl" />
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://testapp.cloudapp.net/Service1.svc"
    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IRestServiceImpl"
    contract="ServiceReference1.IRestServiceImpl" name="BasicHttpBinding_IRestServiceImpl" />
</client>

这是我的服务器配置：

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="WCFServiceWebRole2.Service1Behavior">
      <!-- To avoid disclosing metadata information, set the value below to false 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="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

          maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      <security mode="None">
        <transport clientCredentialType="None" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<services>
  <service name="WCFServiceWebRole2.Service1" behaviorConfiguration="WCFServiceWebRole2.Service1Behavior">        
    <endpoint address="" binding="basicHttpBinding" contract="WCFServiceWebRole2.IRestServiceImpl"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
  </service>

使用多部分格式有什么特殊原因吗？通常这样做是因为您希望在一个请求中发送多个内容。例如，一个文件和一些相关数据，或几个文件，等等。您似乎没有这样做，所以多部分格式只是混淆了问题。除非你有一个很好的理由使用多部分格式，否则我就干脆放弃它。让您的客户端发送原始字节，让服务器代码直接从流中读取，而不使用

MultipartParser

另外，我注意到，一旦你得到了图像数据，你将尝试把它作为UTF8数据读取。我有理由肯定这行不通，而且可能不是

Brian，我理解你的意思，你是对的，我只想通过网络发送一个文件。我将删除这些项目，并让您知道。非常感谢。

    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "PostImage2")]
    string PostImage2(Stream image);

     public string PostImage2(Stream image)
    {
        MultipartParser parser = new MultipartParser(image);

        string content = "testing123";
        try
        {

            if (image == null)
                return "Image stream is null";

            // Read the stream into a byte array
            byte[] data = parser.ToByteArray(image);

            // Copy to a string for header parsing
            content = Encoding.UTF8.GetString(data);

            if (content == "")
                content = "There is no content";
