Question

我正在做一些关于azure概念工作的证明，尝试使用Get Role URL获取角色：

https://management.core.windows.net/<subscription-id>/services/hostedservices/<cloudservice-name>/deployments/<deployment-name>/roles/<role-name>

然后使用更新角色URL更新角色：

https://management.core.windows.net/<subscription-id>/services/hostedservices/<cloudservice-name>/deployments/<deployment-name>/roleinstances/<role-name>

这两个网址都是直接来自msdn网页。 GET请求有效，我得到的XML与我在管理控制台中看到的相匹配。然后，当我向xml添加一个元素并将其与更新URL上的PUT一起发回时，我收到200响应，但我从未在管理控制台中看到更改。当我发送乱码时，我也没有看到任何错误消息。我是从C＃连接的，同事建议我可以得到这个回复：

var response = (HttpWebResponse)request.GetResponse();
Console.WriteLine(response.ToString());

但是这给我带来了404错误。

是否有额外的步骤来提交更新？我怎样才能看到msdn提到的响应？

当我正在快速完成SMAPI工作时，我使用AzureTools（http://blogs.msdn.com/b/kwill/archive/2013/08/26/azuretools-the-diagnostic-utility-used-by-the-windows-azure-developer-support-team.aspx）。具体来说，请查看“服务管理REST API”下的“其他工具”部分。这将向您显示完整的回复。

回答有关如何获取响应的问题（txtSMAPIResponse是AzureTools提供响应信息的地方）：

        System.IO.Stream receiveStream;
    System.IO.StreamReader readStream;
    Encoding encode;

    HttpWebResponse response = null;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (WebException ex)
    {
        txtSMAPIRequest.Text = request.Headers.ToString();
        txtSMAPIResponse.Text = ex.Message + Environment.NewLine + Environment.NewLine + ex.Response.Headers.ToString();
        try
        {
            receiveStream = ex.Response.GetResponseStream();
            encode = System.Text.Encoding.GetEncoding("utf-8");
            // Pipes the stream to a higher level stream reader with the required encoding format. 
            readStream = new System.IO.StreamReader(receiveStream, encode);
            txtSMAPIResponse.Text += readStream.ReadToEnd();

            // Releases the resources of the response.
            response.Close();
            // Releases the resources of the Stream.
            readStream.Close();
        }
        catch
        {
        }
        return;
    }

    txtSMAPIRequest.Text = request.Method + " " + request.RequestUri + " " + request.ProtocolVersion + Environment.NewLine + Environment.NewLine;
    txtSMAPIRequest.Text += request.Headers.ToString();
    txtSMAPIResponse.Text = (int)response.StatusCode + " - " + response.StatusDescription + Environment.NewLine + Environment.NewLine;
    txtSMAPIResponse.Text += response.Headers + Environment.NewLine + Environment.NewLine;

    receiveStream = response.GetResponseStream();
    encode = System.Text.Encoding.GetEncoding("utf-8");
    // Pipes the stream to a higher level stream reader with the required encoding format. 
    readStream = new System.IO.StreamReader(receiveStream, encode);
    txtSMAPIResponse.Text += readStream.ReadToEnd();

    // Releases the resources of the response.
    response.Close();
    // Releases the resources of the Stream.
    readStream.Close();
}

我遇到了同样的问题。在我的情况下，EndPointACL没有得到更新。非常痛苦的事情是每次更新，我们都要发送整个ConfigurationSet;无法更新特定端点的ACL。

典型的更新如下所示：

<?xml version="1.0"?>
<PersistentVMRole xmlns="http://schemas.microsoft.com/windowsazure" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<ConfigurationSets>
    <ConfigurationSet>
        <ConfigurationSetType>NetworkConfiguration</ConfigurationSetType>
        <InputEndpoints>
            <InputEndpoint>
                <LocalPort>100</LocalPort>
                <Name>TCP-100</Name>
                <Port>100</Port>
                <Protocol>tcp</Protocol>
                <EndpointACL>
            <Rules>
              <Rule>
                <Order>1</Order>
                <Action>deny</Action>
                <RemoteSubnet>108.239.229.0/24</RemoteSubnet>
                <Description>test-rule</Description>
              </Rule>
            </Rules>
          </EndpointACL>
            </InputEndpoint>
        </InputEndpoints>
        <SubnetNames>
            <SubnetName>Subnet-1</SubnetName>
        </SubnetNames>
    </ConfigurationSet>
</ConfigurationSets>
</PersistentVMRole>

Windows Azure REST API更新角色不起作用
