问题描述
这是有关Watson Assistant API V1/V2差异的问题. 文档像这样说:
似乎在V2中，上下文由助手自动自动维护".这到底是什么意思?如果我想将一些数据传递给对话框流，则可以在"/message"上使用上下文.是否允许在V2中使用?(是的，似乎.)然后在V1天内，我必须从响应中接收上下文，并在每次请求时将其发送回去.助手还会在V2中发回上下文吗?我的客户端应用程序在V2中应该做什么?任何详细信息都欢迎..谢谢.
首先回答您的第二个问题-如果检查Watson Assistant V2的API文档此处，响应中有一个MessageContext对象，具有全局上下文和特定于技能的上下文值.
您还有一个示例请求，您可以在其中手动传递上下文(全局和用户定义的上下文)
curl -u "apikey:{apikey}" -X POST -H "Content-Type:application/json" -d "{\"input\": {\"text\": \"Hello\"}, \"context\": {\"global\": {\"system\": {\"user_id\": \"my_user_id\"}}}}" "https://gateway.watsonplatform.net/conversation/api/v2/assistants/{assistant_id}/sessions/{session_id}/message?version=2018-11-08"
在客户端，您可以使用此代码
service.message({
assistant_id: '{assistant_id}',
session_id: '{session_id}',
input: {
'message_type': 'text',
'text': 'Hello'
},
context: {
'global': {
'system': {
'user_id': 'my_user_id'
}
},
"skills": {
"main skill": {
"user_defined": {
"my_result_variable": "result_value"
}
}
}
}
}

检查 API方法摘要了解到目前为止V2支持的功能.
在V2中有一个称为Session的新概念.会话用于向技能发送用户输入并接收响应.它还会自动为您维护会话的状态，即上下文".
V2 API(截至今天) 支持运行时方法，这些方法使客户端应用程序可以与(但不能修改)现有助手或技能进行交互.您可以使用这些方法来开发可部署用于生产用途的面向用户的客户端，用于代理助手和另一项服务(例如，聊天服务或后端系统)之间的通信的应用程序或测试应用程序. /p>

curl -u "apikey:<API_KEY>" -X POST -H "Content-Type:application/json" -d "{

}" "https://gateway.watsonplatform.net/assistant/api/v2/assistants/{ASSISTANT_ID}/sessions/{SESSION_ID}/message?version=2018-11-08"
对于会话ID，请运行以下命令
curl -u "apikey:<API_KEY>" -X POST "https://gateway.watsonplatform.net/assistant/api/v2/assistants/{ASSISTANT_ID}/sessions?version=2018-11-08"
响应包括用户定义的技能背景

This is a question about Watson Assistant API V1/V2 difference. The doc says like this:
It seems that in V2, "the context is maintained automatically by the assistant". What does this mean exactly ? If I'd like to pass some data to the dialog flow, I might use context on "/message". Is is allowed in V2?( yes, it seems.) Then in V1 days, I have to receive context from responses and send it back on every request. Does assistant also send the context back in V2? What should my client-app do in V2? Any detailed info is welcomed ..Thanks.
Answering your second question first - If you check the API docs for Watson Assistant V2 here, there is a MessageContext object in the response with Global Context and skill specific context values.
You also have a sample Request where you can manually pass the context (both global and user-defined)
curl -u "apikey:{apikey}" -X POST -H "Content-Type:application/json" -d "{\"input\": {\"text\": \"Hello\"}, \"context\": {\"global\": {\"system\": {\"user_id\": \"my_user_id\"}}}}" "https://gateway.watsonplatform.net/conversation/api/v2/assistants/{assistant_id}/sessions/{session_id}/message?version=2018-11-08"
From the client side, you can use this code
service.message({
assistant_id: '{assistant_id}',
session_id: '{session_id}',
input: {
'message_type': 'text',
'text': 'Hello'
},
context: {
'global': {
'system': {
'user_id': 'my_user_id'
}
},
"skills": {
"main skill": {
"user_defined": {
"my_result_variable": "result_value"
}
}
}
}
}

Check the API Methods Summary to understand what is supported in V2 as of today.
There is a new concept in V2 called Session. A session is used to send user input to a skill and receive responses. It also maintains the state of the conversation which is Context automatically for you.
V2 API as of today supports Runtime Methods, methods that enable a client application to interact with (but not modify) an existing assistant or skill. You can use these methods to develop a user-facing client that can be deployed for production use, an application that brokers communication between an assistant and another service (such as a chat service or back-end system), or a testing application.
The complete cURL example that works for me
curl -u "apikey:<API_KEY>" -X POST -H "Content-Type:application/json" -d "{
\"input\": {
\"text\": \"What's the time?\",
\"options\": {
\"alternate_intents\": true,
\"debug\": true,\"return_context\": true
}
},
\"context\": {
\"global\": {
\"system\": {
\"user_id\": \"derp\",\"turn_count\":1
}
}
},
\"skills\": {
\"main_skill\":{\"user_defined\": {
\"chosen_service\": \"dental\"
}}
}
}" "https://gateway.watsonplatform.net/assistant/api/v2/assistants/{ASSISTANT_ID}/sessions/{SESSION_ID}/message?version=2018-11-08"
for session ID, run this command
curl -u "apikey:<API_KEY>" -X POST "https://gateway.watsonplatform.net/assistant/api/v2/assistants/{ASSISTANT_ID}/sessions?version=2018-11-08"
The response includes user_defined skill context
{"output":{"generic":[{"response_type":"text","text":"Hey ! how are you today? Let me know if you need any help or get stuck looking for information."}],"debug":{"nodes_visited":[{"dialog_node":"node_6_1475611948267","title":null,"conditions":"conversation_start"}],"log_messages":[],"branch_exited":true,"branch_exited_reason":"completed"},"intents":[{"intent":"General_Greetings","confidence":0.32179955244064334},{"intent":"General_Jokes","confidence":0.296911633014679},{"intent":"goodbye","confidence":0.2852578103542328},{"intent":"General_Ending","confidence":0.2513303637504578},{"intent":"off_topic","confidence":0.24435781836509707},{"intent":"select_detail","confidence":0.24206179082393647},{"intent":"list_options","confidence":0.22829059958457948},{"intent":"still-here","confidence":0.22606439888477325},{"intent":"select_service","confidence":0.22488142400979996},{"intent":"General_Security_Assurance","confidence":0.2210852071642876}],"entities":[]},"context":{"global":{"system":{"turn_count":1,"user_id":"derp"}},"skills":{"main skill":{"user_defined":{"chosen_service":"dental"}}}}}
