REST API : 배포 오류 발생 BadRequest

Question

아래 명시된 Create Deployment 메서드에 액세스하려고합니다. http://msdn.microsoft.com/en-us/library/windowsazure/ee460813 패키지를 BLOB에 업로드하고 구성 파일을 탐색했습니다. Azure 포털에서 수동으로 패키지 및 설정 파일을 업로드하려고 시도했는지 확인했습니다. 아래는 AzureEcoystemCloudService가 패키지를 배포하려는 클라우드 서비스 이름 인 배포 작성을 위해 작성한 코드입니다.

byte[] bytes = new byte[fupldConfig.PostedFile.ContentLength + 1]; 
     fupldConfig.PostedFile.InputStream.Read(bytes, 0, bytes.Length); 
     string a = Encoding.UTF8.GetString(bytes, 0, bytes.Length); 
     string base64ConfigurationFile = a.ToBase64(); 
     X509Certificate2 certificate = CertificateUtility.GetStoreCertificate 
     (ConfigurationManager.AppSettings["thumbprint"].ToString()); 


     HostedService.CreateNewDeployment(certificate, ConfigurationManager.AppSettings 
     ["SubscriptionId"].ToString(), "2012-03-01", "AzureEcoystemCloudService", 
     Infosys.AzureEcosystem.Entities.Enums.DeploymentSlot.staging, 
     "AzureEcoystemDeployment", "http://shubhendustorage.blob.core.windows.net/shubhendu 
     storage/Infosys.AzureEcoystem.Web.cspkg", "AzureEcoystemDeployment", 
     base64ConfigurationFile, true, false);

    But every time we are getting the below error from the line 

    response = (HttpWebResponse)request.GetResponse(); 

    <Error xmlns="http://schemas.microsoft.com/windowsazure" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
     <Code>BadRequest</Code> 
     <Message>The specified configuration settings for Settings are invalid. Verify that the service configuration file is a valid XML file, and that role instance counts are specified as positive integers.</Message> 

</Error> 

감사합니다, Shubhendu

나는 푸른 나머지 API에 대한 요청과 문제를 했어. WebException의 응답을 읽는 것이 매우 중요하다는 것을 알게되었습니다.

try 
{ 
    //Call Azure REST API 
} 
catch(WebException ex) 
{ 
    var err = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd(); 

    Console.WriteLine(err); 

    throw; 
} 

이렇게하면 요청의 기본 문제에 대한 충분한 정보를 얻을 수 있습니다.

Azure SDK 2.2부터는 문서가 끝나고 잘못된 구성 문자열을 base64로 인코딩 할 필요가 없습니다. 따라서 모든 byte [] 변환을 base64로하는 대신 UFT8 문자열을 전달하십시오.
