如何在Python中使用dialogflow客户端

Question

我正在尝试的是在 python 中获得响应import dialogflowfrom google.api_core.exceptions import InvalidArgumentDIALOGFLOW_PROJECT_ID = 'imposing-fx-333333'DIALOGFLOW_LANGUAGE_CODE = 'en'GOOGLE_APPLICATION_CREDENTIALS = 'imposing-fx-333333-e6e3cb9e4adb.json'text_to_be_analyzed = "Hi! I'm David and I'd like to eat some sushi, can you help me?"session_client = dialogflow.SessionsClient()session = session_client.session_path(DIALOGFLOW_PROJECT_ID, SESSION_ID)text_input = dialogflow.types.TextInput(text=text_to_be_analyzed, language_code=DIALOGFLOW_LANGUAGE_CODE)query_input = dialogflow.types.QueryInput(text=text_input)try:    response = session_client.detect_intent(session=session, query_input=query_input)except InvalidArgument:    raiseprint("Query text:", response.query_result.query_text)print("Detected intent:", response.query_result.intent.display_name)print("Detected intent confidence:", response.query_result.intent_detection_confidence)print("Fulfillment text:", response.query_result.fulfillment_text)我无法验证凭据google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and re-run the application. For more information, please see https://cloud.google.com/docs/authentication/getting-started这是我在 stackoverflow 中的第一个问题:)我知道我已经做了很多

Answer 1

您需要从 导出服务帐户密钥 (JSON)文件，并将环境变量设置GOOGLE_APPLICATION_CREDENTIALS为包含服务帐户密钥的 JSON 文件的文件路径。然后你就可以调用dialogflow了。

获取服务帐户密钥的步骤： 确保您使用的是 Dialogflow v2。转到常规设置并单击您的服务帐户。这会将您重定向到 Google Cloud Platform 项目的服务帐户页面。下一步是为服务帐户创建新密钥。现在创建一个服务帐户并选择 JSON 作为输出密钥。按照说明操作，JSON 文件将下载到您的计算机。该文件将用作GOOGLE_APPLICATION_CREDENTIALS.

现在在代码中，

import os

import dialogflow

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "/path/to/file.json"

project_id = "your_project_id"

session_id = "your_session_id"

language_code = "en"

session_client = dialogflow.SessionsClient()

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

如果您想从文件系统中获取文件，此方法也适用。推荐的方法是使用环境变量

    import json

    from google.cloud import dialogflow_v2

    from google.oauth2 import *

session_client = None

dialogflow_key = None

creds_file = "/path/to/json/file.json"

dialogflow_key = json.load(open(creds_file))

credentials = (service_account.Credentials.from_service_account_info(dialogflow_key))

session_client = dialogflow_v2.SessionsClient(credentials=credentials)

print("it works : " + session_client.DEFAULT_ENDPOINT) if session_client is not None 

else print("does not work")
