Azure服务管理api更改配置

Question

我是一名学生，我正在尝试创建一个应用程序，该应用程序允许用户更改Azure上托管服务的实例计数。这是通过上传服务的新配置文件(http://msdn.microsoft.com/en-us/library/windowsazure/ee460809.aspx)来完成的。我的问题是，当我试图在下面的代码中获得响应时，我一直收到错误消息"The remote server returned an error：(403) server“。我认为这个错误一定与证书有关，但我可以成功地执行get请求，并使用我在这里使用的相同证书获得正确的响应。任何帮助在很大程度上都是appreciated.config的新配置文件。

公共空配置( string serviceName，string deploymentSlot，string changeConfiguration，string deploymentName)

    {

        byte[] encodedConfigbyte = new byte[config.Length];
        encodedConfigbyte = System.Text.Encoding.UTF8.GetBytes(config);
        string encodedConfig = Convert.ToBase64String(encodedConfigbyte);

        Uri changeConfigRequestUri = new Uri("https://management.core.windows.net/" + subscriptionId + "/services/hostedservices/" + serviceName + "/deployments/" + deploymentName + "/?comp=config)");

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

        request.Headers.Add("x-ms-version", "2010-10-28");
        request.Method = "POST";

        string bodyText = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                          "<ChangeConfiguration xmlns=\"http://schemas.microsoft.com/windowsazure" + ">" + "<Configuration>" + encodedConfig + "</Configuration>" + "<TreatWarningsAsError>false</TreatWarningsAsError>" + "<Mode>Auto</Mode>"+"</ChangeConfiguration>";

        byte[] buf = Encoding.UTF8.GetBytes(bodyText);
        request.ContentType = "text/xml";
        request.ContentLength = buf.Length;

        StreamWriter writer = new StreamWriter(request.GetRequestStream());
        var data = Encoding.ASCII.GetBytes(buf.ToString());

            {
                throw;
            }
        }


        X509Certificate2Collection certCollection = certStore.Certificates.Find(X509FindType.FindByThumbprint, thumbprint, false);
        certStore.Close();

        if (certCollection.Count == 0)
        {
            throw new Exception("Error: No certificate found containing thumbprint " + thumbprint);

看起来您的内容类型不正确。这是API调用的要求之一。

您必须：

request.ContentType = "text/xml";

你应该有：

request.ContentType = "application/xml";

另外，有没有什么原因将x-ms-version设置为"2010-10-28“而不是最新的API "2011-08-01"；

参考：http://msdn.microsoft.com/en-us/library/windowsazure/ee460809.aspx

编辑:我还有点担心你如何添加你的身体数据。看起来您正在将文本转换为UTF8字节数组，然后对字节数组执行tostring操作，并将其重新编码为ascii字节数组。这对我来说很奇怪。您应该能够将字符串直接传递到StreamWriter的Write(bodyText)方法中。API可能不知道如何解码您发送的正文数据。

试试这样的..。

    request.ContentType = "application/xml";

    using (var writer = new StreamWriter(request.GetRequestStream()))
    {
         writer.Write(bodyText);
    }
