REST API：創建部署拋出錯誤BadRequest

Question

我們正在嘗試訪問下面所述的創建部署方法 http://msdn.microsoft.com/en-us/library/windowsazure/ee460813 我們已將Package上載到Blob中並瀏覽配置文件。我們檢查了試圖手動上傳Azure門戶中的軟件包和配置文件，它的工作正常。 以下是我們爲創建部署而編寫的代碼，其中「AzureEcoystemCloudService」是我們想要部署我們的軟件包的雲服務名稱。

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,

     } 
     return requestId; 
    } 




    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> 

感謝， Shubhendu

我已經與湛藍的休息API請求的問題。我發現閱讀WebException的響應是無價的。

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

    Console.WriteLine(err); 

    throw; 
} 

這應該爲您提供有關請求潛在問題的足夠信息。

從Azure SDK 2.2開始，它最終的文檔是錯誤的，您不需要base64編碼配置字符串。因此，不要將所有byte []轉換爲base64，只需傳入一個UFT8字符串。
