Agentapplicatie in SDK voor Microsoft 365-agenten

Maak een subklasse van AgentApplication en registreer uw handlers in de constructor. Het hostingframework injecteert AgentApplicationOptionsautomatisch .

public class MyAgent : AgentApplication
{
    public MyAgent(AgentApplicationOptions options) : base(options)
    {
        OnConversationUpdate(ConversationUpdateEvents.MembersAdded, WelcomeAsync);
        OnActivity(ActivityTypes.Message, OnMessageAsync, rank: RouteRank.Last);
    }

    private async Task WelcomeAsync(ITurnContext context, ITurnState state, CancellationToken ct)
    {
        foreach (var member in context.Activity.MembersAdded)
        {
            if (member.Id != context.Activity.Recipient.Id)
            {
                await context.SendActivityAsync("Hello! How can I help you?", cancellationToken: ct);
            }
        }
    }

    private async Task OnMessageAsync(ITurnContext context, ITurnState state, CancellationToken ct)
    {
        await context.SendActivityAsync($"You said: {context.Activity.Text}", cancellationToken: ct);
    }
}

Registreer uw agent in Program.cs:

WebApplicationBuilder builder = WebApplication.CreateBuilder(args);

builder.Services.AddHttpClient();
builder.Services.AddSingleton<IStorage, MemoryStorage>();
builder.Services.AddAgent<MyAgent>();
builder.Services.AddAgentAspNetAuthentication(builder.Configuration);

WebApplication app = builder.Build();

app.UseAuthentication();
app.UseAuthorization();
app.MapAgentApplicationEndpoints(requireAuth: !app.Environment.IsDevelopment());

app.Run();

Instantieer AgentApplication en registreer handlers op het exemplaar met behulp van de Fluent API. Start de server door startServer aan te roepen vanuit het Express-hostingpakket.

import { AgentApplication, MemoryStorage, TurnContext, TurnState } from '@microsoft/agents-hosting'
import { startServer } from '@microsoft/agents-hosting-express'

const app = new AgentApplication<TurnState>({ storage: new MemoryStorage() })

app.onConversationUpdate('membersAdded', async (context: TurnContext) => {
    await context.sendActivity('Hello! How can I help you?')
})

app.onActivity('message', async (context: TurnContext, state: TurnState) => {
    await context.sendActivity(`You said: ${context.activity.text}`)
})

startServer(app)

Voor handmatig instellen van Express zonder startServer:

import express from 'express'
import { CloudAdapter, authorizeJWT, AuthConfiguration } from '@microsoft/agents-hosting'

const authConfig: AuthConfiguration = loadAuthConfigFromEnv()
const adapter = new CloudAdapter(authConfig)
const expressApp = express()

expressApp.use(express.json())
expressApp.use(authorizeJWT(authConfig))

expressApp.post('/api/messages', async (req, res) => {
    await adapter.process(req, res, async (context) => {
        await app.run(context)
    })
})

Instantieer AgentApplication met een typeparameter en registreer handlers met behulp van decorators.

from microsoft_agents.hosting.core import AgentApplication, TurnState, TurnContext, MemoryStorage
from microsoft_agents.hosting.aiohttp import CloudAdapter, start_agent_process
from aiohttp.web import Request, Response, Application, run_app

AGENT_APP = AgentApplication[TurnState](
    storage=MemoryStorage(),
    adapter=CloudAdapter()
)

@AGENT_APP.conversation_update("membersAdded")
async def on_members_added(context: TurnContext, state: TurnState):
    await context.send_activity("Hello! How can I help you?")

@AGENT_APP.activity("message")
async def on_message(context: TurnContext, state: TurnState):
    await context.send_activity(f"You said: {context.activity.text}")

if __name__ == "__main__":
    async def messages(req: Request) -> Response:
        return await start_agent_process(req, AGENT_APP, AGENT_APP.adapter)

    app = Application()
    app.router.add_post("/api/messages", messages)
    app["agent_app"] = AGENT_APP
    app["adapter"] = AGENT_APP.adapter
    run_app(app, host="localhost", port=3978)

OnMessage("help", async (context, state, ct) =>
{
    await context.SendActivityAsync("Here's what I can do...", cancellationToken: ct);
});

Berichten vergelijken met een reguliere expressie:

OnMessage(new Regex(@"^order\s+\d+$", RegexOptions.IgnoreCase), async (context, state, ct) =>
{
    await context.SendActivityAsync("Looking up your order...", cancellationToken: ct);
});

app.onMessage('help', async (context: TurnContext, state: TurnState) => {
    await context.sendActivity("Here's what I can do...")
})

Berichten vergelijken met een reguliere expressie:

app.onMessage(/^order\s+\d+$/i, async (context: TurnContext, state: TurnState) => {
    await context.sendActivity('Looking up your order...')
})

@AGENT_APP.message("/help")
async def on_help(context: TurnContext, state: TurnState):
    await context.send_activity("Here's what I can do...")

Berichten vergelijken met een reguliere expressie:

import re

@AGENT_APP.message(re.compile(r"^order\s+\d+$", re.IGNORECASE))
async def on_order(context: TurnContext, state: TurnState):
    await context.send_activity("Looking up your order...")

OnConversationUpdate(ConversationUpdateEvents.MembersAdded, async (context, state, ct) =>

    foreach (var member in context.Activity.MembersAdded)
    {
        if (member.Id != context.Activity.Recipient.Id)
        {
            await context.SendActivityAsync("Welcome!", cancellationToken: ct);
        }
    }
});

OnConversationUpdate(ConversationUpdateEvents.MembersRemoved, async (context, state, ct) =>
{
    // Called when participants leave the conversation
});

app.onConversationUpdate('membersAdded', async (context: TurnContext) => {
    for (const member of context.activity.membersAdded ?? []) {
        if (member.id !== context.activity.recipient.id) {
            await context.sendActivity('Welcome!')
        }
    }
})

app.onConversationUpdate('membersRemoved', async (context: TurnContext) => {

@AGENT_APP.conversation_update("membersAdded")
async def on_members_added(context: TurnContext, state: TurnState):
    for member in context.activity.members_added or []:
        if member.id != context.activity.recipient.id:

OnActivity(ActivityTypes.Message, async (context, state, ct) =>
{
    // Handles all message activities
});

OnActivity(ActivityTypes.Event, async (context, state, ct) =>
{
    // Handles event activities
});

Gebruik ActivityTypes constanten in plaats van vastgelegde tekenreeksen.

app.onActivity('message', async (context: TurnContext, state: TurnState) => {
    // Handles all message activities
})

app.onActivity('event', async (context: TurnContext, state: TurnState) => {
    // Handles event activities
})

@AGENT_APP.activity("message")
async def on_message(context: TurnContext, state: TurnState):
    pass  # Handles all message activities

@AGENT_APP.activity("event")
async def on_event(context: TurnContext, state: TurnState):
    pass  # Handles event activities

// Specific handlers use the default rank
OnMessage("status", HandleStatusAsync);
OnMessage("help", HandleHelpAsync);

// Catch-all — handles anything not matched above
OnActivity(ActivityTypes.Message, HandleUnknownMessageAsync, rank: RouteRank.Last);

// Specific handlers use the default rank
app.onMessage('status', handleStatusAsync)
app.onMessage('help', handleHelpAsync)

// Catch-all — handles anything not matched above
app.onActivity('message', handleUnknownMessageAsync, RouteRank.Last)

@AGENT_APP.message("/status")
async def on_status(context: TurnContext, state: TurnState):
    await context.send_activity("Status: OK")

@AGENT_APP.message("/help")
async def on_help(context: TurnContext, state: TurnState):
    await context.send_activity("Here's what I can do...")

# Catch-all — handles anything not matched above (registered last)
@AGENT_APP.activity("message")
async def on_unknown(context: TurnContext, state: TurnState):
    await context.send_activity("I didn't understand that. Type /help for options.")

OnBeforeTurn(async (context, state, ct) =>
{
    logger.LogInformation("Turn started: {Type}", context.Activity.Type);
    return true; // Return false to abort the turn
});

OnAfterTurn(async (context, state, ct) =>
{
    logger.LogInformation("Turn completed");
    return true; // Return false to skip state saving
});

OnTurnError(async (context, state, exception, ct) =>
{
    logger.LogError(exception, "Turn error");
    await context.SendActivityAsync("Something went wrong. Please try again.", cancellationToken: ct);
});

Wanneer retourneert , wordt de beurt afgebroken en worden er geen routes uitgevoerd. Wanneer OnAfterTurnfalse retourneert, wordt de status van de schakelaar niet opgeslagen.

app.beforeTurn(async (context: TurnContext, state: TurnState) => {
    console.log(`Turn started: ${context.activity.type}`)
