python - 采用 Dialogflow 意图并查询 Firestore

Question

我的聊天机器人是在 Dialogflow 中创建的，我现在正尝试从 Python 访问它，以获取用户输入并在 GUI 中显示输出(想想一个基本的聊天机器人 gui)。

我已将我的 Python 环境连接到 Dialogflow 和 firestore，

这是检测意图的代码；

#Detection of Dialogflow intents, project and input.
def detect_intent_texts(project_id, session_id, texts, language_code):
   #Returns the result of detect intent with texts as inputs, later can implement same `session_id` between requests allows continuation of the conversaion.
    import dialogflow_v2 as dialogflow
    session_client = dialogflow.SessionsClient()

    session = session_client.session_path(project_id, session_id)
#To ensure session path is correct - print('Session path: {}\n'.format(session))

    for text in texts:
        text_input = dialogflow.types.TextInput(text=text, language_code=language_code)
        query_input = dialogflow.types.QueryInput(text=text_input)
        response = session_client.detect_intent(session=session, query_input=query_input)

        print ('Chatbot:{}\n'.format(response.query_result.fulfillment_text))
detect_intent_texts("chat-8","abc",["Hey"],"en-us")

我需要以某种方式说如果这个意图被触发，从数据库中获取一些东西并显示给用户。

更新

我当前的完整代码，在我看来一切正常，但它抛出了一个我不明白的错误，感谢 Sid8491 到目前为止的帮助。

简而言之，我的问题是，我以前的代码允许我输入一些内容，聊天机器人会做出响应，这一切都在控制台中，但它有效......新代码应该允许我说“当这个意图是触发，执行此操作"

if intentName == 'CourseEnquiry':
    reponse = getCourse()
    print json.dumps({
        'fulfillmentText': reponse,
    })
elif intentName == 'Greetings':
    print "Yo"

detect_intent_texts("chat-8","abc", queryText,"en-us")

但是我得到这个错误:

是的，我认为您走在正确的轨道上。

您需要从dialogFlow 得到的响应中提取intentName 或actionaName 并调用相应的函数，然后将响应发回给用户。

res = detect_intent_texts("chat-8","abc",["Hey"],"en-us")
action = res['queryResult']['action']

if action == 'getSomethingFromDb':
    reponse = someFunction(req)
    return json.dumps({
        'fulfillmentText': reponse,
    })
elif action == 'somethingElse':
    ....

如果你想让它使用 intentName 而不是 actionName 那么你可以提取 intentName 如下所示

intentName = res['query_result']['intent']['display_name']

示例 -

import dialogflow
import os, json

def getCourse():
    doc_ref = db.collection(u"Course_Information").document(u"CourseTypes")
    try:
        doc = doc_ref.get()
        return 'Document data: {}'.format(doc.to_dict())
    except google.cloud.exceptions.NotFound:
        return 'Not found'

def detect_intent_text(project_id, session_id, text, language_code):
    GOOGLE_APPLICATION_CREDENTIALS="C:\\pyth_to_...\\cred.json"
    session_client = dialogflow.SessionsClient(GOOGLE_APPLICATION_CREDENTIALS)

    session = session_client.session_path(project_id, session_id)

    text_input = dialogflow.types.TextInput(
        text=text, language_code=language_code)

    query_input = dialogflow.types.QueryInput(text=text_input)

    response = session_client.detect_intent(
        session=session, query_input=query_input)

queryText = 'get courses of Python' # you will call some function to get text from your app

res = detect_intent_text('project_1234', 'session-test', queryText, 'en')
intentName = res['query_result']['intent']['display_name']

if intentName == 'getCourse':
    reponse = getCourse()
    return json.dumps({
        'fulfillmentText': reponse,
    })

尝试上面的示例并根据您对应用程序的需求进行更改。我的建议是首先让 DialogFlow 在没有应用程序的情况下工作，然后将其与应用程序集成。否则您将无法了解问题是出现在 DialogFlow 中还是您的应用中。

希望对您有所帮助。
