C++調用C#管理Azure虛擬機

爲了使用自己寫的C++程序管理Azure虛擬機，查了好幾天資料，開始的思路是使用cmd命令調用powershell來管理，寫了幾天腳本後發現cmd下只能運行一些簡單的powershell命令，一套腳本在powershell下運行沒有問題，但是在cmd下使用powershell ./script.p1 就會報一大堆錯，跟微軟的工程師溝通後瞭解到沒有支持C++的SDK，只能使用python、.net等語言進行管理，結合我自身的情況我在python和c#中進行選擇，考慮後決定使用C++調用C#來進行管理，在官方文檔中找到了一套流程，是使用properties文件進行認證加載，但是在運行過程中會報錯，結合微軟工程師給我的文檔，我將我所需求的功能總結出來，全部正常運行後，做成以下內容：

一、設置身份驗證：
1、登錄到powershell，記下有關用戶和訂閱的信息：
Login-AzureRmAccount -Environment "AzureChinaCloud"
2、在powershell中創建服務主體，會返回ApplicationId，注意記錄下來：
# Create the service principal (use a strong password) //自己寫DisplayName和Password的值
$sp = New-AzureRmADServicePrincipal -DisplayName "AzureDotNetTest" -Password "password"
# Give it the permissions it needs...
New-AzureRmRoleAssignment -ServicePrincipalName $sp.ApplicationId -RoleDefinitionName Contributor
# Display the Application ID, because we'll need it later.
$sp | Select DisplayName, ApplicationId
3、記錄所需數據：
subscription：使用運行 Login-AzureRmAccount 後返回的 SubscriptionId 值。
client：使用服務主體輸出中的 ApplicationId 值。
key：使用運行 New-AzureRmADServicePrincipal（不帶引號）時分配的 -Password 參數。
tenant：使用運行 Login-AzureRmAccount 後返回的 TenantId 值。

二、創建新項目
1、創建新的控制檯應用程序項目。爲此，請在 Visual Studio 中依次單擊“文件”、“新建”、“項目...”。在 Visual C# 模板下選擇“控制檯應用(.NET Core)”，爲項目命名，並單擊“確定”。
創建新的控制檯應用後，依次單擊“工具”、“NuGet 包管理器”、“包管理器控制檯”打開包管理器控制檯。在控制檯中，執行以下三個命令來獲取所需的包，第一個就足夠我本次對虛擬機的管理了：
# Azure Management Libraries for .NET (Fluent)
Install-Package Microsoft.Azure.Management.Fluent
# Azure Store client libraries
Install-Package WindowsAzure.Storage
# SQL Database client libraries
Install-Package System.Data.SqlClient
2、編輯應用程序的 Program.cs 文件。如果要在新創建的程序中使用，必須加入所需引用，程序如下（我新建立的，將以下程序做成dll由c++調用）：

            string ipAddress = "10.1.1.11";
            CreateNextSelfImageVM(vmName, ipAddress);
        }

    }
}

上方的幾個命令基本可以滿足我的虛擬機管理需求，還有更多的功能可以點出來，針對虛擬機，鏡像和其他資源的操作。

在C++程序中，我使用以下方法使用這些函數，這裏只舉了一個例子，其他類似：

#using "..\\apps\\x64\\Debug\\CSharpUtil.dll"
using namespace CSharpUtil;
using namespace System;
using namespace std;

DLL_API bool CreateNextSelfImageVM(const wchar_t *wcvmName,const wchar_t *wcipAddress){
	AzureUtil ^azureUtil=gcnew AzureUtil;
	String ^wstrvmName=gcnew String(wcvmName);
	String ^wstripAddress=gcnew String(wcipAddress);
	return azureUtil->CreateNextSelfImageVM(wstrvmName,wstripAddress);
}

所有函數均以bool值返回，如果創建失敗會catch到出錯，返回false。沒有事物的概念，可能網卡創建成功，但是虛擬機創建失敗，這些我都是進行手動管理的，在利用redis管理虛擬機信息後，只要保證數據不出錯且網絡不中斷，基本上不會出錯。
