使用 C# 管理 Azure 时序见解第 1 代环境的参考数据

Artículo
11/11/2024

注意

时序见解服务将于 2024 年 7 月 7 日停用。请考虑尽快将现有环境迁移到备用解决方案。有关弃用和迁移的详细信息，请访问我们的文档。

注意

这是一篇 Gen1 文章。

本文演示如何将 C#、MSAL.NET 和 Microsoft Entra ID 结合使用来向 Azure 时序见解 Gen 1 参考数据管理 API 发出编程性 API 请求。

提示

查看 https://github.com/Azure-Samples/Azure-Time-Series-Insights 上的 GA C# 代码示例。

总结

下面的示例代码演示了以下功能：

使用 MSAL.NET PublicClientApplication 获取访问令牌。
针对 Gen 1 参考数据管理 API 的顺序创建、读取、更新和删除操作。
常见的响应代码，包括常见错误代码。

参考数据管理 API 单独处理每个项，一个项出现错误不会阻止其他项成功完成。例如，如果你的请求包含 100 个项，其中一个项发生错误，则会写入 99 个项，并拒绝一个项。

先决条件和设置

在编译和运行示例代码之前，请完成以下步骤：

预配 Gen 1 Azure 时序见解环境。
在环境中创建参考数据集。使用以下参考数据方案：

项名类型

uuid 字符串
为 Microsoft Entra ID 配置 Azure 时序见解环境，如身份验证和授权中所述。使用 http://localhost:8080/ 作为“重定向 URI”。
安装必需的项目依赖项。
编辑下面的示例代码，将每个 #PLACEHOLDER# 替换为相应的环境标识符。
在项目的根目录中运行 dotnet run。出现提示时，使用你的用户配置文件登录到 Azure。

项名	类型
uuid	字符串

项目依赖项

建议使用最新版本的 Visual Studio 和 NETCore.app：

Visual Studio 2019 - 版本 16.4.2+
NETCore.app - 版本 2.2.8

示例代码包含两个必需的依赖项：

MSAL.NET Microsoft.Identity.Client - 4.7.1 包。
Newtonsoft.Json - 12.0.3 包。

使用 NuGet 2.12+ 添加包：

dotnet add package Newtonsoft.Json --version 12.0.3
dotnet add package Microsoft.Identity.Client --version 4.7.1

或：

声明一个 csharp-tsi-msal-ga-sample.csproj 文件：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <LangVersion>latest</LangVersion>
    <RootNamespace>csharp-tsi-msal-ga-sample</RootNamespace>
    <RunWorkingDirectory>$(MSBuildThisFileDirectory)</RunWorkingDirectory>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Identity.Client" Version="4.7.1.0" Culture="neutral" PublicKeyToken="0a613f4dd989e8ae" />
    <PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
  </ItemGroup>
</Project>

然后运行 dotnet restore。
