Creación de mensajes propios para recopilar datos de entrada del usuario
Artículo
SE APLICA A: SDK v4
A menudo, una conversación entre un usuario y un bot implica mostrar preguntas (avisos) al usuario para obtener información, analizar la respuesta del usuario y, a continuación, actuar en dicha información. El bot debe hacer un seguimiento del contexto de una conversación, para que pueda controlar su comportamiento y recordar las respuestas a las preguntas anteriores. El estado de un bot es la información que sigue con el fin de responder de forma adecuada a los mensajes entrantes.
Sugerencia
La biblioteca de diálogos proporciona avisos incorporados que proporcionan más funcionalidad que pueden usar los usuarios. Se pueden encontrar ejemplos de estos avisos en el artículo Implementación de un flujo de conversación secuencial.
Nota:
Los SDK de JavaScript, C# y Python de Bot Framework seguirán siendo compatibles, pero el SDK de Java se va a retirar con la compatibilidad final a largo plazo que finaliza en noviembre de 2023.
Los bots existentes creados con el SDK de Java seguirán funcionando.
El bot de ejemplo le formula al usuario una serie de preguntas, valida algunas de sus respuestas y guarda sus comentarios. El siguiente diagrama muestra la relación entre el bot, el perfil de usuario y las clases de flujos de conversación.
Una clase UserProfile para la información de usuario que recopilará el bot.
Una clase ConversationFlow para controlar el estado de la conversación mientras se recopila información del usuario.
Una enumeración ConversationFlow.Question interna para el seguimiento de dónde nos encontramos en la conversación.
Una clase userProfile para la información de usuario que recopilará el bot.
Una clase conversationFlow para controlar el estado de la conversación mientras se recopila información del usuario.
Una enumeración conversationFlow.question interna para el seguimiento de dónde nos encontramos en la conversación.
Una clase UserProfile para la información de usuario que recopilará el bot.
Una clase ConversationFlow para controlar el estado de la conversación mientras se recopila información del usuario.
Una enumeración ConversationFlow.Question interna para el seguimiento de dónde nos encontramos en la conversación.
Una clase UserProfile para la información de usuario que recopilará el bot.
Una clase ConversationFlow para controlar el estado de la conversación mientras se recopila información del usuario.
Una enumeración ConversationFlow.Question interna para el seguimiento de dónde nos encontramos en la conversación.
El estado del usuario realiza un seguimiento del nombre, edad y fecha elegida del usuario, y el estado de conversación, un seguimiento de lo que se acaba de preguntar al usuario.
Dado que no tiene previsto implementar este bot, configurará el estado del usuario y de la conversación para utilizar el almacenamiento en memoria.
Se usa el controlador de turnos de mensaje del bot y las propiedades de estado de usuario y de conversación para administrar el flujo de la conversación y la colección de entradas. En el bot, se registrará la información de propiedad de estado que se reciba durante cada iteración del controlador de turnos de mensajes.
Cree los objetos de estado del usuario y la conversación en el inicio y, para consumirlos, inserte dependencias en el constructor del 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>();
Cree los objetos de estado del usuario y la conversación en index.js y consúmalos en el constructor del 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;
Construya customPromptBot en el método getBot mediante las instancias ConversationState y UserState proporcionadas por el contenedor de Spring. El constructor de CustomPromptBot almacenará referencias a ConversationState y UserState proporcionados durante el inicio.
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;
Cree los objetos de estado del usuario y la conversación en app.py y consúmalos en el constructor del 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
Creación de los descriptores de acceso de la propiedad
Cree descriptores de acceso de propiedad para las propiedades de perfil de usuario y flujo de conversación y, a continuación, llame a GetAsync para recuperar el valor de propiedad del estado.
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);
Antes de que finalice el turno, llame a SaveChangesAsync para escribir los cambios de estado en el almacenamiento.
Cree descriptores de acceso de propiedad para las propiedades de perfil de usuario y flujo de conversación y, a continuación, llame a get para recuperar el valor de propiedad del estado.
Antes de que finalice el turno, llame a saveChanges para escribir los cambios de estado en el almacenamiento.
/**
* Override the ActivityHandler.run() method to save state changes after the bot logic completes.
*/
async run(context) {
await super.run(context);
// Save any state changes. The load happened during the execution of the Dialog.
await this.conversationState.saveChanges(context, false);
await this.userState.saveChanges(context, false);
}
Cree descriptores de acceso de propiedad para las propiedades de perfil de usuario y flujo de conversación y, a continuación, llame a get para recuperar el valor de propiedad del estado.
En el constructor, se crearán los descriptores de acceso de la propiedad de estado y se configurarán los objetos de administración de estados (que se crearon anteriormente) para nuestra conversación.
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)
Antes de que finalice el turno, llame a SaveChangesAsync para escribir los cambios de estado en el almacenamiento.
# Save changes to UserState and ConversationState
await self.conversation_state.save_changes(turn_context)
await self.user_state.save_changes(turn_context)
Controlador de turno de mensajes
Al controlar las actividades de mensaje, el controlador de mensajes utiliza un método auxiliar para administrar la conversación y preguntar al usuario. El método auxiliar se describe en la siguiente sección.
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)
Rellenado del perfil de usuario
El bot solicita información al usuario, en función de la pregunta que el bot hizo en el turno anterior. La entrada se analiza con un método de validación.
Cada método de validación sigue un diseño similar:
El valor devuelto indica si la entrada es una respuesta válida para esta pregunta.
Si la validación es correcta, se genera un valor normalizado y analizado para guardarlo.
Si se produce un error de validación, se genera un mensaje con el que el bot puede volver a pedir la información.
En las siguientes secciones se describen los métodos de validación.

Análisis y validación de la entrada
El bot usa los siguientes criterios para validar la entrada.
El nombre debe ser una cadena que no esté vacía. Para normalizarlo, se recortan los espacios en blanco.
La edad debe estar entre 18 y 120. Para normalizarlo, devuelve un entero.
La fecha debe ser cualquier fecha u hora al menos una hora en el futuro.
Para normalizarlo, se devuelve solo la parte de fecha de la entrada analizada.
Nota:
Para la entrada de edad y fecha, el ejemplo usa bibliotecas Microsoft/Recognizers-Text para realizar el análisis inicial.
Esta es solo una manera de analizar la entrada. Para más información acerca de estas bibliotecas, consulte el archivo Léame del proyecto.
