Web 搜索

Web 搜索允许代理在 Web 中搜索 up-to日期信息。 此工具使代理能够回答有关当前事件的问题、查找文档以及访问其训练数据之外的信息。

注释

Web 搜索可用性取决于基础代理提供程序。 有关提供程序特定的支持，请参阅 提供程序概述 。

以下示例演示如何使用 Web 搜索工具创建代理：

using System;
using Azure.AI.OpenAI;
using Azure.Identity;
using Microsoft.Agents.AI;
using Microsoft.Extensions.AI;

// Requires: dotnet add package Microsoft.Agents.AI.OpenAI --prerelease
var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT")
    ?? throw new InvalidOperationException("AZURE_OPENAI_ENDPOINT is not set.");
var deploymentName = Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT_NAME") ?? "gpt-4o-mini";

// Create an agent with the web search (Bing grounding) tool
AIAgent agent = new AzureOpenAIClient(new Uri(endpoint), new AzureCliCredential())
    .GetChatClient(deploymentName)
    .AsAIAgent(
        instructions: "You are a helpful assistant that can search the web for current information.",
        tools: [new WebSearchToolDefinition()]);

Console.WriteLine(await agent.RunAsync("What is the current weather in Seattle?"));
