Créer vos propres invites pour collecter des entrées utilisateur
Article
S'APPLIQUE À : SDK v4
Une conversation entre un bot et un utilisateur implique souvent une demande (invite) d’informations à l’utilisateur, l’analyse de sa réponse et l’action en fonction des informations obtenues. Votre bot doit suivre le contexte d’une conversation pour pouvoir gérer son comportement et se rappeler des réponses aux questions précédentes. L’état d’un bot représente des informations qu’il suit pour répondre correctement aux messages entrants.
Conseil
La bibliothèque de dialogues propose des invites prédéfinies fournissant de nouvelles fonctionnalités que les utilisateurs peuvent utiliser. Vous trouverez des exemples de ces invites dans l’article Implémenter des flux de conversation séquentiels.
Remarque
Les kits SDK JavaScript, C# et Python Bot Framework continueront d’être pris en charge. Toutefois, le kit de développement logiciel (SDK) Java est mis hors service avec une prise en charge finale à long terme se terminant en novembre 2023.
Les bots existants créés avec le kit de développement logiciel (SDK) Java continueront de fonctionner.
L’exemple de bot pose à l’utilisateur une série de questions, valide certaines de ses réponses et enregistre son entrée. Le diagramme suivant montre la relation entre le bot, le profil utilisateur et les classes de flux de conversation.
Une classe UserProfile pour les informations utilisateur qui seront collectées par le bot.
Une classe ConversationFlow pour contrôler l’état de notre conversation pendant la collecte des informations utilisateur.
Une énumération ConversationFlow.Question interne pour le suivi d'où vous en êtes dans la conversation.
Une classe userProfile pour les informations utilisateur qui seront collectées par le bot.
Une classe conversationFlow pour contrôler l’état de notre conversation pendant la collecte des informations utilisateur.
Une énumération conversationFlow.question interne pour le suivi d'où vous en êtes dans la conversation.
Une classe UserProfile pour les informations utilisateur qui seront collectées par le bot.
Une classe ConversationFlow pour contrôler l’état de notre conversation pendant la collecte des informations utilisateur.

Une classe UserProfile pour les informations utilisateur qui seront collectées par le bot.
Une classe ConversationFlow pour contrôler l’état de notre conversation pendant la collecte des informations utilisateur.
Une énumération ConversationFlow.Question interne pour le suivi d'où vous en êtes dans la conversation.
L'état de l'utilisateur permet de connaître son nom, son âge et la date choisie, tandis que l'état de la conversation effectue le suivi de la dernière question posée à l'utilisateur.
Étant donné que vous ne prévoyez de déployer ce bot, vous allez configurer un état d'utilisateur et de conversation pour utiliser le stockage en mémoire.
Vous utilisez le gestionnaire de tour de messages du bot ainsi que les propriétés d'état utilisateur et de conversion pour gérer le flux de la conversation et la collection d'entrée. Dans notre bot, nous allons enregistrer les informations de propriétés d'état reçues pendant chaque itération du gestionnaire de tour de messages.
Créez les objets d’état utilisateur et de conversation au démarrage et consommez-les via l’injection de dépendance du constructeur de bot.
Startup.cs
// Create the Bot Adapter with error handling enabled.
services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();
// Create the storage we'll be using for User and Conversation state. (Memory is great for testing purposes.)
services.AddSingleton<IStorage, MemoryStorage>();
// Create the User state.
services.AddSingleton<UserState>();
// Create the Conversation state.
services.AddSingleton<ConversationState>();
Créez les objets d’état utilisateur et de conversation dans index.js et consommez-les dans le constructeur de bot.
index.js
// Catch-all for errors.
adapter.onTurnError = async (context, error) => {
// This check writes out errors to console log .vs. app insights.
// NOTE: In production environment, you should consider logging this to Azure
bots/customPromptBot.js
class CustomPromptBot extends ActivityHandler {
constructor(conversationState, userState) {
super();
// The state management objects for the conversation and user.
this.conversationState = conversationState;
this.userState = userState;
Construisez le CustomPromptBot dans la méthode getBot en utilisant les instances ConversationState et UserState fournies par le conteneur Spring. Le constructeur de CustomPromptBot stocke les références à ConversationState et UserState fournies au démarrage.
Application.java
@Bean
public Bot getBot(
ConversationState conversationState,
UserState userState
) {
return new CustomPromptBot(conversationState, userState);
}
CustomPromptBot.java
private final BotState userState;
private final BotState conversationState;
public CustomPromptBot(ConversationState conversationState, UserState userState) {
this.conversationState = conversationState;
this.userState = userState;
Créez les objets d’état utilisateur et de conversation dans app.py et consommez-les dans le constructeur de bot.
app.py
CONVERSATION_STATE = ConversationState(MEMORY)
# Create Bot
BOT = CustomPromptBot(CONVERSATION_STATE, USER_STATE)
# Listen for incoming requests on /api/messages.
bots/custom_prompt_bot.py
class CustomPromptBot(ActivityHandler):
def __init__(self, conversation_state: ConversationState, user_state: UserState):
if conversation_state is None:
raise TypeError(
"[CustomPromptBot]: Missing parameter. conversation_state is required but None was given"
)
if user_state is None:
raise TypeError(
"[CustomPromptBot]: Missing parameter. user_state is required but None was given"
)
self.conversation_state = conversation_state
self.user_state = user_state
Créez des accesseurs de propriété pour les propriétés du profil utilisateur et du flux de conversation, puis appelez GetAsync pour récupérer la valeur de la propriété à partir de l’état.
Bots/CustomPromptBot.cs
protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
var conversationStateAccessors = _conversationState.CreateProperty<ConversationFlow>(nameof(ConversationFlow));
var flow = await conversationStateAccessors.GetAsync(turnContext, () => new ConversationFlow(), cancellationToken);
var userStateAccessors = _userState.CreateProperty<UserProfile>(nameof(UserProfile));
var profile = await userStateAccessors.GetAsync(turnContext, () => new UserProfile(), cancellationToken);
Avant la fin du tour, appelez SaveChangesAsync pour écrire les modifications d’état dans le stockage.
Créez des accesseurs de propriété pour les propriétés du profil utilisateur et du flux de conversation, puis appelez get pour récupérer la valeur de la propriété à partir de l’état.
Avant la fin du tour, appelez saveChanges pour écrire les modifications d’état dans le stockage.
/**

*/
async run(context) {

Dans le constructeur, nous créons les accesseurs de propriété d'état et vous configurez les objets de gestion des états (créés ci-dessus) pour notre conversation.
bots/custom_prompt_bot.py
async def on_message_activity(self, turn_context: TurnContext):
# Get the state properties from the turn context.
profile = await self.profile_accessor.get(turn_context, UserProfile)
flow = await self.flow_accessor.get(turn_context, ConversationFlow)
Avant la fin du tour, appelez SaveChangesAsync pour écrire les modifications d’état dans le stockage.
# Save changes to UserState and ConversationState
await self.conversation_state.save_changes(turn_context)
await self.user_state.save_changes(turn_context)
Gestionnaire de messages
Lors de la gestion des activités de message, le gestionnaire de messages utilise une méthode d’assistance pour gérer la conversation et afficher des invites pour l’utilisateur. La méthode d’assistance est décrite dans la section suivante.
async def on_message_activity(self, turn_context: TurnContext):
# Get the state properties from the turn context.
profile = await self.profile_accessor.get(turn_context, UserProfile)
flow = await self.flow_accessor.get(turn_context, ConversationFlow)
await self._fill_out_user_profile(flow, profile, turn_context)
# Save changes to UserState and ConversationState
await self.conversation_state.save_changes(turn_context)
await self.user_state.save_changes(turn_context)
Remplissage du profil utilisateur
Le bot invite l’utilisateur à fournir des informations, en fonction de la question que le bot a posée lors du tour précédent (le cas échéant). L’entrée est analysée à l’aide d’une méthode de validation.
Chaque méthode de validation fonctionne plus ou moins de la même manière :
La valeur de retour indique si l’entrée est une réponse valide pour cette question.
Si la validation réussit, elle génère une valeur analysée et normalisée pour l’enregistrer.
Si la validation échoue, elle génère un message avec lequel le bot peut redemander les informations.
Les méthodes de validation sont décrites dans la section suivante.

Analyser et valider l’entrée
Le bot utilise les critères suivants pour valider l’entrée.
Le nom doit être une chaîne non vide. Il est normalisé quand les espaces blancs sont supprimés.
L’âge doit être une valeur comprise entre 18 et 120. Il est normalisé quand un nombre entier est retourné.
La date doit être de n’importe quelle date ou heure située au moins une heure dans le futur.
Elle est normalisée quand seule la partie concernant la date de l’entrée analysée est retournée.
Remarque
Pour l'âge et la date d'entrée, l'échantillon d'utilisation fait appel aux bibliothèques Microsoft/Recognizers-Text pour effectuer l'analyse initiale.
Il s'agit simplement d'une façon d'analyser l'entrée. Pour plus d'informations sur ces bibliothèques, consultez le fichier LISEZMOI du projet.
