Question

问题：当通过https客户端发送到WCF休息服务时，会收到400个错误请求。

这一切都在测试环境中运行，没有任何问题。测试网络可以通过https运行，但是post方法因400错误请求而失败。

测试和prod之间的唯一区别是web配置我必须添加行为和绑定才能获得测试webget方法的工作。但我无法弄清楚导致帖子失败的原因。

我还尝试过最初添加特定的端点和服务，并找到了使用标准端点的更好解决方案。所以我删除了端点和服务，因为这应该通过global.asax文件正确注册。

任何帮助，建议，或者看到显而易见的，我确信我现在看了100次。

服务代码：

[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class Uploader
 {
    [WebGet(UriTemplate = "Test")]
    public String Test()
    {
        return "connected";
    }

    [OperationContract]
    [WebInvoke(UriTemplate = "UploadClaim/{fileName}/{device_id}/{fSize}", Method = "POST")]
    public String UploadClaim(string fileName, string device_id, string fSize, Stream zipFile)
    {
       // Handle post request and store file
    }

}

的Global.asax：

void Application_Start(object sender, EventArgs e)
{
    RouteTable.Routes.Add(new ServiceRoute("uploads", new WebServiceHostFactory(), typeof(Uploader)));

}

的Web.config：

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

<behaviors>
  <serviceBehaviors>
    <behavior name="">
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />

    <!--

        via the attributes on the <standardEndpoint> element below
    -->
    <standardEndpoint name="" helpEnabled="true" defaultOutgoingResponseFormat="Json" maxReceivedMessageSize="67108864" 
    transferMode="Buffered">
    <security mode="Transport">

        </security>
    </standardEndpoint>

  </webHttpEndpoint>
</standardEndpoints>


</system.serviceModel>

客户要求：

  // This url is not the actual but not the problem.  
  //  The only difference from test to  prod is http vs https
requestUrl = "https://MyDomain.com/uploads/UploadClaim/{FILENAME}/{DEVICE_ID}/{FSIZE}";



            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);

            request.Method = "POST";

            request.ContentType = "application/octet-stream";

            request.Timeout = 1000000;

            request.KeepAlive = true;

            request.AllowWriteStreamBuffering = true;

            //request.SendChunked = true;

            //request.ContentType = "application/octet-stream";

            //FileStream inputStream = File.OpenRead(strfPath);

            //request.ContentLength = inputStream.Length;



            byte[] fileToSend = File.ReadAllBytes(strfPath);

            request.ContentLength = fileToSend.Length;



            //Byte[] buffer = new Byte[inputStream.Length];

            ///Stream requestStream = request.GetRequestStream();

            using(Stream requestStream = request.GetRequestStream()){

                bool canWrite = requestStream.CanWrite;

                // Send the file as body request.

                requestStream.Write(fileToSend, 0, fileToSend.Length);



                requestStream.Flush();

                requestStream.Close();

            }

哇，船长明显终于出现了。

感谢Aaron Hoffman在这篇文章中的回答：Large WCF web service request failing with (400) HTTP Bad Request

添加以下诊断信息可帮助我确定IIS_USER帐户对我尝试编写的目录没有写入权限。即使该目录位于站点目录中。添加了IIS_USER写入文件夹的权限，没有更多问题。

希望这可以帮助别人忽视像我这样明显的人：）

<system.diagnostics>
<sources>
    <source name="System.ServiceModel"
              switchValue="Information, ActivityTracing"
              propagateActivity="true">
