快速入门：创建新代理

先决条件

• Azure 订阅 - 免费创建订阅。
• 确保创建帐户和项目的个人在订阅范围内具有 Azure AI 帐户所有者 角色
  • 或者，在订阅级别具有 参与者 或 认知服务参与者 角色也满足此要求。

在 Azure AI Foundry 门户中创建 Foundry 帐户和项目

若要在 Azure AI Foundry 中创建帐户和项目，请执行以下步骤：

1. 转到 Azure AI Foundry。 如果你已进入项目，请选择页面左上角的“Azure AI Foundry”以转到“主页”。

2. 使用“代理入门”创建流程以获得最快的体验。 单击“ 创建代理”。

   

3. 输入项目的名称。 如果要自定义默认值，请选择 “高级”选项。

   

4. 选择 创建。

5. 等待资源预配。

   1. 将创建帐户和项目（帐户的子资源）。
   2. gpt-4o 模型将自动部署
   3. 将创建默认代理

6. 完成后，你将直接进入代理工作区，可以开始创建代理。

   

   注释

   如果在尝试配置或创建代理时遇到权限错误，请确保项目上有 Azure AI 用户 。

先决条件

• 设置代理环境
• 将 Azure AI 用户RBAC 角色 分配给需要使用 SDK 或代理 Playground 创建或编辑代理的每个团队成员
  • 必须在项目范围内分配此角色
  • 所需的最低权限： agents/*/read、 agents/*/action、 agents/*/delete

配置并运行代理

创建 .NET 控制台项目。

dotnet new console

将 .NET 包安装到项目。 例如，如果使用 .NET CLI，请运行以下命令。

dotnet add package Azure.AI.Agents.Persistent
dotnet add package Azure.Identity

接下来，为了验证 API 请求并运行程序，请使用 az login 命令登录 Azure 订阅。

az login

使用以下代码创建并运行代理。 若要运行此代码，需要获取项目的终结点。 此字符串采用以下格式：

https://<AIFoundryResourceName>.services.ai.azure.com/api/projects/<ProjectName>

例如，终结点可能如下所示：

https://myresource.services.ai.azure.com/api/projects/myproject

在名为 ProjectEndpoint.. 的 appsetting 变量中设置此终结点。

using Azure;
using Azure.AI.Agents.Persistent;
using Azure.Identity;
using Microsoft.Extensions.Configuration;
using System.Diagnostics;

IConfigurationRoot configuration = new ConfigurationBuilder()
    .SetBasePath(AppContext.BaseDirectory)
    .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
    .Build();

var projectEndpoint = configuration["ProjectEndpoint"];
var modelDeploymentName = configuration["ModelDeploymentName"];

//Create a PersistentAgentsClient and PersistentAgent.
PersistentAgentsClient client = new(projectEndpoint, new DefaultAzureCredential());

//Give PersistentAgent a tool to execute code using CodeInterpreterToolDefinition.
PersistentAgent agent = client.Administration.CreateAgent(
    model: modelDeploymentName,
    name: "My Test Agent",
    instructions: "You politely help with math questions. Use the code interpreter tool when asked to visualize numbers.",
    tools: [new CodeInterpreterToolDefinition()]
);

//Create a thread to establish a session between Agent and a User.
PersistentAgentThread thread = client.Threads.CreateThread();

//Ask a question of the Agent.
client.Messages.CreateMessage(
    thread.Id,
    MessageRole.User,
    "Hi, Agent! Draw a graph for a line with a slope of 4 and y-intercept of 9.");

//Have Agent beging processing user's question with some additional instructions associated with the ThreadRun.
ThreadRun run = client.Runs.CreateRun(
    thread.Id,
    agent.Id,
    additionalInstructions: "Please address the user as Jane Doe. The user has a premium account.");

//Poll for completion.
do

    Thread.Sleep(TimeSpan.FromMilliseconds(500));
    run = client.Runs.GetRun(thread.Id, run.Id);
}
while (run.Status == RunStatus.Queued
    || run.Status == RunStatus.InProgress
    || run.Status == RunStatus.RequiresAction);

//Get the messages in the PersistentAgentThread. Includes Agent (Assistant Role) and User (User Role) messages.
Pageable<PersistentThreadMessage> messages = client.Messages.GetMessages(
    threadId: thread.Id,
    order: ListSortOrder.Ascending);

//Display each message and open the image generated using CodeInterpreterToolDefinition.
foreach (PersistentThreadMessage threadMessage in messages)
{
    foreach (MessageContent content in threadMessage.ContentItems)
    {
        switch (content)
        {
            case MessageTextContent textItem:
                Console.WriteLine($"[{threadMessage.Role}]: {textItem.Text}");
                break;
            case MessageImageFileContent imageFileContent:
                Console.WriteLine($"[{threadMessage.Role}]: Image content file ID = {imageFileContent.FileId}");
                BinaryData imageContent = client.Files.GetFileContent(imageFileContent.FileId);
                string tempFilePath = Path.Combine(AppContext.BaseDirectory, $"{Guid.NewGuid()}.png");
                File.WriteAllBytes(tempFilePath, imageContent.ToArray());
                client.Files.DeleteFile(imageFileContent.FileId);

                ProcessStartInfo psi = new()
                {
                    FileName = tempFilePath,
                    UseShellExecute = true
                };
                Process.Start(psi);
                break;
        }
    }
}

//Clean up test resources.
client.Threads.DeleteThread(threadId: thread.Id);
client.Administration.DeleteAgent(agentId: agent.Id);

  • 必须在项目范围内分配此角色
  • 所需的最低权限： agents/*/read、 agents/*/action、 agents/*/delete

配置并运行代理

此代码中的关键对象包括：

• AgentsClient
• ToolUtility

首先，通过运行来初始化新项目：

npm init -y

运行以下命令以安装所需的 npm 包。

npm install @azure/ai-agents @azure/identity
npm install dotenv

接下来，为了验证 API 请求并运行程序，请使用 az login 命令登录 Azure 订阅。

az login

使用以下代码创建并运行上传 CSV 数据的 代理，然后从该数据生成条形图。 若要运行此代码，需要获取项目的终结点。 此字符串采用以下格式：

https://<AIFoundryResourceName>.services.ai.azure.com/api/projects/<ProjectName>

例如，终结点如下所示：

https://myresource.services.ai.azure.com/api/projects/myproject

将此终结点设置为文件中命名 PROJECT_ENDPOINT 的 .env 环境变量。

先决条件

• 设置代理环境
• 将 Azure AI 用户RBAC 角色 分配给需要使用 SDK 或代理 Playground 创建或编辑代理的每个团队成员
  • 必须在项目范围内分配此角色
  • 所需的最低权限： agents/*/read、 agents/*/action、 agents/*/delete

配置并运行代理

API 调用信息

为了验证 API 请求，请使用 az login 命令登录 Azure 订阅。

az login

接下来，你需要获取 Entra ID 令牌，用作对 API 调用的授权。 使用 CLI 命令提取令牌：

az account get-access-token --resource 'https://ai.azure.com' | jq -r .accessToken | tr -d '"'

将访问令牌设置为名为 AGENT_TOKEN 的环境变量。

若要成功对 Azure AI Foundry 代理服务进行 REST API 调用，需要使用终结点，如下所示：

https://<your_ai_service_name>.services.ai.azure.com/api/projects/<your_project_name>

例如，终结点可能如下所示：

https://exampleaiservice.services.ai.azure.com/api/projects/project

将此终结点设置为名为 AZURE_AI_FOUNDRY_PROJECT_ENDPOINT 的环境变量。
