问题
I am trying to use the new API version V2 for IBM Cloud Watson Assistant. Instead of sending a message for a workspace I need to send a message to an assistant. The context structure has global and skill-related sections now.
How would my app pass in values as context variables? Where in the structure would they need to be placed? I am using the Python SDK. I am interested in sending information as part of client dialog actions.
回答1:
Based on testing the Python SDK and the API V2 using a tool, I came to the following conclusion. Context is provided by the assistant if it is requested as part of the input options.
"context": {
"skills": {
"main skill": {
"user_defined": {
"topic": "some chatbot talk",
"skip_user_input": true
}
}
},
"global": {
"system": {
"turn_count": 2
}
}
}
To pass back values from my client / app to the assistant, I could use the context parameter. However, in contrast to the V1 API I needed to place the key / value pairs "down below" in the user_defined part:
context['skills']['main skill']['user_defined'].update({'mydateOUT':'2018-10-08'})
The above is a code snippet from this sample file for a client action. With that placement of my context variables everything works and I can implement client actions using the API Version 2.
