在Dialogflow V2 API中的EventInput中设置参数 [英] set parameters in EventInput in Dialogflow V2 API

问题描述

我拼命尝试在

  dialogflow.types.EventInput 
  

在python中。

此

/ EventInput

解决方案

这是我的操作方式：

 从google.protobuf导入对话流
导入struct_pb2 
 
 session_client = dialogflow.SessionsClient（）
 session = session_client.session_path（project_id，session_id）
 
参数= struct_pb2.Struct（）
参数[给定名称] ='Jeff'
 parameters [ last-name] ='Bridges'
 
 query_input = {
'event'：{
 name： greetPerson ，
 parameters：参数，
 language_code： de 
} 
} 
 
 response = session_client.detect_intent（
 session = session，
 query_input = query_input）
  

注意：

在dialogflow控制台中，必须将参数的默认值指定为＃even_name.parameter_name 。

在这种情况下，参数给定名称则为 #greetPe rson.given-name ，对于 lastname ，它将是＃greetPerson.last-name 。

文档参考：

我们正在使用 DetectIntent ，我们在其中使用 QueryInput ，最后我们在其中使用 EvenInput

希望它会有所帮助。

I desperatly try to set parameters in a

dialogflow.types.EventInput

in python.

This doc says the parameters need to be of type Struct.

I read here that the parameters needs to be a google.protobuf.Struct. But it does not work for me.

Is there another Struct type equivalent in python?

If i send the EventInput without parameters, the intent is detected correctly.

I tried this so far:

import dialogflow_v2 as dialogflow
session_client = dialogflow.SessionsClient()

session = session_client.session_path(project_id, session_id)
parameters = struct_pb2.Struct()
parameters['given-name'] = 'Jeff'
parameters['last-name'] = 'Bridges'

event_input = dialogflow.types.EventInput(         
    name='greetPerson',
    language_code='de',
    parameters=parameters)

query_input = dialogflow.types.QueryInput(event=event_input)

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

Anybody having experience with this usecase?

Things i also tried:

1. Pass a class named p yields:

   Parameter to MergeFrom() must be instance of same class: expected Struct got p. for field EventInput.parameters

2. Pass a dict:

   parameters = {
       'given-name': 'Jeff',
       'last-name': 'Bridges'} 
   

   yields:

   Protocol message Struct has no "given-name" field.

3. Generate Struct with constructor:

   from google.protobuf.struct_pb2 import Struct, Value
   parameters = Struct(fields={
       'given-name':Value(string_value='Jeff'),
       'last-name':Value(string_value='Bidges')
   })
   

   yields sometimes:

   Exception in thread ptvsd.stopping (most likely raised during interpreter shutdown):

/EventInput

解决方案

This is how I did this:

import dialogflow
from google.protobuf import struct_pb2

session_client = dialogflow.SessionsClient()
session = session_client.session_path(project_id, session_id)

parameters = struct_pb2.Struct()
parameters["given-name"] = 'Jeff'
parameters["last-name"] = 'Bridges'

query_input = {
    'event': {
        "name": "greetPerson",
        "parameters": parameters,
        "language_code": "de"
    }
}

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

Note:
In dialogflow console, you must give default values of parameters as #even_name.parameter_name.
In this case for parameter given-name it would be #greetPerson.given-name and for last-name it would be #greetPerson.last-name.

Docs Reference:
We are using DetectIntent, in which we are using QueryInput, in which finally we are using EvenInput
