如何使用Flask向Google Dialogflow提交查询

from flask import Flask, request
from google.cloud import dialogflow

import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "path/to/your/service_account.json"

app = Flask(__name__)

@app.route('/query', methods=['POST'])
def send_query():
    # 获取用户输入的查询文本
    query_text = request.form['query']
    
    # 创建一个与Dialogflow的会话客户端
    session_client = dialogflow.SessionsClient()
    
    # 设置Dialogflow的项目ID和会话ID
    project_id = 'your-project-id'
    session_id = 'unique-session-id'
    
    session = session_client.session_path(project_id, session_id)
    
    # 创建一个查询文本输入
    text_input = dialogflow.TextInput(text=query_text, language_code='en')
    query_input = dialogflow.QueryInput(text=text_input)
    
    # 发送查询请求并获取响应
    response = session_client.detect_intent(request={'session': session, 'query_input': query_input})
    
    # 从响应中提取回复文本
    reply_text = response.query_result.fulfillment_text
    
    # 返回回复给用户
    return reply_text

if __name__ == '__main__':
    app.run()
