python - Python AGI 脚本导致 Asterisk 错误 510

问题描述

我正在尝试用星号整合谷歌对话流，以在我的其他 agi 聊天机器人脚本之一中使用。但是，我在使用星号执行脚本时遇到了问题。该脚本在从命令行运行时工作正常，但在通过星号运行时失败，知道为什么吗？我在 centos 服务器上使用基本安装的 Python 2.7。运行槽星号时的脚本在以下行失败： session_client = dialogflow.SessionsClient() （通过在每个通道打印一个数字并检查何时抛出错误来检查这一点）

脚本：

#!/usr/bin/python
import dialogflow
import sys
import json

def detect_intent_texts(project_id, session_id, texts, language_code):
    """Returns the result of detect intent with texts as inputs.

    Using the same `session_id` between requests allows continuation
    of the conversation."""

    import dialogflow_v2 as dialogflow
    session_client = dialogflow.SessionsClient()

    session = session_client.session_path(project_id, session_id)
    print('Session path: {}\n'.format(session))

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

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

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

    print('=' * 20)
    print('Query text: {}'.format(response.query_result.query_text))
    print('Detected intent: {} (confidence: {})\n'.format(
        response.query_result.intent.display_name,
        response.query_result.intent_detection_confidence))
    print('Fulfillment text: {}\n'.format(
        response.query_result.fulfillment_text))
try:
  detect_intent_texts("fake-219706", 34, "hallo dit is nick vaes","nl")
except:
  print("error")

在命令行上运行时的输出：

[root@stage-ai agi-bin]# ./DF.py
Session path: projects/fake-219706/agent/sessions/34

====================
Query text: hallo dit is nick vaes
Detected intent: Default Welcome Intent (confidence: 1.0)

Fulfillment text: Goedemorgen zoekt u een groep of een persoon?

拨号方案：

same => n,Answer()
same => n,agi(DF.py)

解决方案

您的脚本有时会在 STDOUT 中打印单词“错误”。

Asterisk AGI 规范没有“错误”命令，所以它告诉你错误。

像这样的代码是非常糟糕的做法，因为你不知道你得到了哪个异常。

except:
  print("error")
