Using IBM Watson with php and Curl

Good morning, I'm trying to use the IBM chatbot service on watson. As a test I created my workflow for a simple pizza order.

At the beginning of the call he welcomes you and asks you which pizza I want.

It validates 3 information 1- Quantity 2- flavor 3- If it goes refrigerant together

In the watson test in the web panel it works the conversation perfectly as I programmed it. but when I give the entry in the curl it keeps repeating the start even if I answer the information the same way I did in the input to chatweb test of the ibm site

Follow my cod curl

    curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Basic NDkzYzBmZWItMzg2MC00O6RiLTkyMjUtM2E0ODc4MDMxODY3OmGFTFUzdUd1a0NDRg==' -d '{ \ 
   "input": { \ 
     "text": "" \ 
   }   \ 
 }' 'https://watson-api-explorer.mybluemix.net/conversation/api/v1/workspaces/9ec1ac11-786d-4c2d-9d8a-528265e3bcbb/message?version=2017-02-03'

and it returns me this json

{
  "intents": [],
  "entities": [],
  "input": {
    "text": ""
  },
  "output": {
    "log_messages": [],
    "text": [
      "bem vindo a pizzaria smartphone. quantas pizzas o senhor deseja pedir hoje?"
    ],
    "nodes_visited": [
      "inicio"
    ]
  },
  "context": {
    "conversation_id": "3f4b12da-2c3c-4b04-a94e-2da688ece806",
    "system": {
      "dialog_stack": [
        {
          "dialog_node": "inicio"
        }
      ],
      "dialog_turn_counter": 1,
      "dialog_request_counter": 1,
      "_node_output_map": {
        "inicio": [
          0
        ]
      }
    }
  }
}

How should I resend another request so that it continues in the same conversation and does not show me the start again every time I do the curl.

I tried to send it as follows and it still has problems:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Basic NDkzYzBmZWItMzg2MC00O6RiLTkyMjUtM2E0ODc4MDMxODY3OmGFTFUzdUd1a0NDRg==' -d '{ \ 
   "input": { \ 
     "text": "quero uma pizza" \ 
   }, \ 
   "context": { \ 
     "conversation_id": "3f4b12da-2c3c-4b04-a94e-2da688ece806" \ 
    } \ 
 }' 'https://watson-api-explorer.mybluemix.net/conversation/api/v1/workspaces/9ec1ac11-786d-4c2d-9d8a-528265e3bcbb/message?version=2017-02-03'

and it returns me the beginning again:

{
  "intents": [
    {
      "intent": "qtd-pizza",
      "confidence": 0.9523983001708984
    }
  ],
  "entities": [
    {
      "entity": "qtd-pizza",
      "location": [
        6,
        9
      ],
      "value": "1",
      "confidence": 1
    },
    {
      "entity": "sys-number",
      "location": [
        6,
        9
      ],
      "value": "1",
      "confidence": 1,
      "metadata": {
        "numeric_value": 1
      }
    }
  ],
  "input": {
    "text": "quero uma pizza"
  },
  "output": {
    "log_messages": [],
    "text": [
      "bem vindo a pizzaria smartphone. quantas pizzas o senhor deseja pedir hoje?"
    ],
    "nodes_visited": [
      "inicio"
    ]
  },
  "context": {
    "conversation_id": "3f4b12da-2c3c-4b04-a94e-2da688ece806",
    "system": {
      "dialog_stack": [
        {
          "dialog_node": "inicio"
        }
      ],
      "dialog_turn_counter": 1,
      "dialog_request_counter": 1,
      "_node_output_map": {
        "inicio": [
          0
        ]
      }
    }
  }
}

I would like guidance on how to proceed. Reading the json, curl and etc. I'm doing through a php and just need help with the working logic of watson. Thank you in advance for your attention.

Hello. I'm not sure yet, but I believe the problem is in the context of your request.

You should save all the context you received in the first response (including conversation_id, system, dialog_turn_counter, dialog_request_counter and context vars if you have one) and then send it when you make a new request.

In your example you are sending the context only with the conversation_id.

You can see examples of this in the documentation here:

link

// Prompt for the next round of input.
var newMessageFromUser = prompt('>> ');
// Send back the context to maintain state.
conversation.message({
  input: { text: newMessageFromUser },
  context : response.context, <--- O context é devolvido da mesma forma que o Watson envia.
}, processResponse)
