Python Asterisk 510中出现错误

Question

我正在尝试用星号初始化google对话框流，以便在我的另一个agi聊天机器人脚本中使用。但是我在使用星号执行脚本时遇到了一个问题。当从命令行运行时，这个脚本运行得很好，但是在通过星号运行时，它会失败，知道为什么吗？我使用的是centos服务器上基本安装的Python2.7。当通过星号运行时，脚本在以下行失败：session_client=dialogflow.SessionsClient() （通过在每个通道上打印一个数字并在抛出错误时进行检查来检查）

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：

^{pr2}$

星号输出：

您的脚本在某个时刻将单词“error”打印到STDOUT中。在

Asterisk AGI规范没有“error”命令，所以它告诉您错误。在

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。在

except:
  print("error")
