Question

我正在按照教程Windows Azure SDK for Node.js - Compute Management来管理虚拟机。

我使用azure account cert export将pem文件下载到<Subscription GUID>.pem。

该脚本目前包含：

var subscriptionId ="<Subscription GUID>";
var pem = "<Subscription GUID>.pem";

var computeManagementClient = computeManagement.createComputeManagementClient(computeManagement.createCertificateCloudCredentials({
    subscriptionId: subscriptionId,
    pem: fs.readFileSync(pem)
}));

当我从Node.js运行它时会产生错误：

C:\Apps\azure\node_modules\azure-mgmt-compute\node_modules\azure-common\lib\util\validate.js:416
  throw new Error('Required argument ' + name + ' for function ' + func + ' is
        ^

问题在于pem: fs.readFileSync(pem)。 SDK未将节点缓冲区转换为字符串。有issue on Github。

在修复此问题之前，请在缓冲区上使用toString：

pem: fs.readFileSync(pem).toString()

使用节点sdk通过Azure进行身份验证时出错：
