休息API : Create Deployment throwing error BadRequest

Question

我们正在尝试访问下面所述的创建部署方法 http://msdn.microsoft.com/en-us/library/windowsazure/ee460813 我们已经在 blob 中上传了 Package 并浏览了配置文件。我们已检查尝试在 Azure 门户中手动上传包和配置文件，其工作正常。 下面是我们为创建部署而编写的代码，其中“AzureEcoystemCloudService”是我们要在其中部署包的云服务名称。

    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,

        storage/Infosys.AzureEcoystem.Web.cspkg", "AzureEcoystemDeployment", 
        base64ConfigurationFile, true, false);

            response.Close();
        }
        if (!statusCode.Equals(expectedCode))
        {
            throw new ApplicationException(string.Format(
                "Call to {0} returned an error:{1}Status Code: {2} ({3}):{1}{4}",
                uri.ToString(),
                Environment.NewLine,
                (int)statusCode,
                statusCode,
                responseBody.ToString(SaveOptions.OmitDuplicateNamespaces)));
        }
        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>

谢谢， 舒本杜

我在 Azure Rest API 上请求时遇到了问题。我发现阅读 WebException 的响应非常有值(value)。

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

    Console.WriteLine(err);

    throw;
}

这应该为您提供有关请求的根本问题的足够信息。
