身份验证失败，因为远程方在调用rest api到Azure api应用程序服务时关闭了传输流 [英] Authentication failed because the remote party has closed the transport stream while calling rest api to Azure api app service

问题描述

我正在尝试针对Azure应用服务使用rest api在.Net 4.0内置的客户端应用程序中进行身份验证.

I am trying to authenticate in client application built in .Net 4.0 using rest api against the Azure app service.

如果我们已经将应用程序部署到了Azure虚拟机，则相同的应用程序可以正常工作，但是如果将应用程序部署为

Same application works fine if we have application deployed to the azure vm but does not work if application is adeployed as 

azure应用服务.调用api的代码如下:

azure app service.Code for calling api is as follows:

字符串requestURL = ServiceBaseUrl + serviceURI;
HttpWebRequest webRequest =(HttpWebRequest)WebRequest.Create(requestURL);
webRequest.Method = Convert.ToString(method);
webRequest.Headers [HttpRequestHeader.Authorization] ="accesstoken =" + SecurityToken;

if(方法== HttpMethod.POST ||方法== HttpMethod.PUT)
{
开关(contentType)
{
case ContentType.JSON:
webRequest.ContentType =" application/json" ;;
break;
case ContentType.BINARY:
webRequest.ContentType ="application/octet-stream";
break;
case ContentType.FORM:
webRequest.ContentType ="application/x-www-form-urlencoded";
break;
默认值:
break;
}
}
IAsyncResult asyncResult = webRequest.BeginGetRequestStream(new AsyncCallback(requestStreamCallback)，requestContext)

string requestURL = ServiceBaseUrl + serviceURI;
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(requestURL);
webRequest.Method = Convert.ToString(method);
webRequest.Headers[HttpRequestHeader.Authorization] = "accesstoken=" + SecurityToken;

if (method == HttpMethod.POST || method == HttpMethod.PUT)
{
switch (contentType)
{
case ContentType.JSON:
webRequest.ContentType = "application/json";
break;
case ContentType.BINARY:
webRequest.ContentType = "application/octet-stream";
break;
case ContentType.FORM:
webRequest.ContentType = "application/x-www-form-urlencoded";
break;
default:
break;
}
}
IAsyncResult asyncResult = webRequest.BeginGetRequestStream(new AsyncCallback(requestStreamCallback), requestContext)

有人可以帮助我吗?

谢谢
