如果我在Watson的对话中设置了上下文对象,我希望它仍然是它先前访问过的节点我的意思是:
在点燃'意图'之后,如果我输入'再见'(再见意图)。它应该触发一个再见的Intent,但它只适用于测试工具。
以下是我的Nodejs应用程序中的代码:
let context = {}
const conversation = new ConversationV1({
username: 'myUsername',
password: 'myPassword',
url: 'https://gateway.watsonplatform.net/conversation/api',
version_date: '2017-05-26'
})
conversation.message({ workspace_id: workspaceId}, function (err, response) {
if (err) {
console.log(err)
} else {
context = response.context
}
})
sendMessage = (message = null) => new Promise((resolve, reject) => {
conversation.message({
input: {text: message},
workspace_id: workspaceId,
context: context
}, function (err, response) {
if (err) {
reject(err)
} else {
resolve(response.output.text)
}
})
}
虽然conversation_id总是一样的。我总是得到 anythingelse的Intent响应而不是再见'Intent。
{ intents: [ { intent: 'greetings', confidence: 1 } ],
entities: [],
input: { text: 'hi' },
output:
{ text: [ 'It is nice to talk to you, again !' ],
nodes_visited: [ 'greetings' ],
log_messages: [] },
context:
{ conversation_id: '7cc96494-d108-4dc9-95c4-63c174f20b4c',
system:
{ dialog_stack: [Object],
dialog_turn_counter: 2,
dialog_request_counter: 2,
_node_output_map: [Object] } } }
{ intents: [ { intent: 'goodbytes', confidence: 1 } ],
entities: [],
input: { text: 'bye' },
output:
{ text: [ 'I didn\'t understand. You can try rephrasing.' ],
nodes_visited: [ 'Anything else' ],
log_messages: [] },
context:
{ conversation_id: '7cc96494-d108-4dc9-95c4-63c174f20b4c',
system:
{ dialog_stack: [Object],
dialog_turn_counter: 2,
dialog_request_counter: 2,
_node_output_map: [Object],
branch_exited: true,
branch_exited_reason: 'completed' } } }

Dialog本身是无状态的,你必须使用context var来维护它。

我发现上下文对象的重要部分是保持对话的“上下文”并使用嵌套的意图继续传递你在每个http响应中拥有的新上下文对象。
let context = {}
sendMessage = (message = null) => new Promise((resolve, reject) => {
conversation.message({
input: {text: message},
workspace_id: workspaceId,
context: context
}, function (err, response) {
if (err) {
reject(err)
} else {
context = response.context
resolve(response.output.text)
}
})
}
这意味着您必须更新每个http请求中的上下文对象:
context = response.context
正如您在每个http响应中看到的那样,您正在更新 _node_output_map :
{ conversation_id: '1bb7b7e3-2bc2-4686-8f5e-8e25cdff7ff8',
system:
{ dialog_stack: [ [Object] ],
dialog_turn_counter: 1,
dialog_request_counter: 1,
_node_output_map: { Welcome: [Object] },
branch_exited: true,
branch_exited_reason: 'completed' } }
{ conversation_id: '1bb7b7e3-2bc2-4686-8f5e-8e25cdff7ff8',
system:
{ dialog_stack: [ [Object] ],
dialog_turn_counter: 2,
dialog_request_counter: 2,
_node_output_map: { Welcome: [Object], greetings: [Object] } } }
