使用输出上下文响应来操纵特定上下文 [英] manipulating a specific context using output context response

问题描述

我目前正在尝试使用webhook响应以及我从找到，以下方法应该起作用:

I'm currently trying to change a specific value of one of my context using webhook response and from what I found, the following should work:

       {
            "fulfillmentText": ${textToSpeech},
            "fulfillmentMessages": [{ "text": { "text": [${text}] } }],
            "payload": {
                "google": {
                    "expectUserResponse": true,
                    "richResponse": {
                        "items": [
                            {
                                "simpleResponse": {
                                    "textToSpeech": ${textToSpeech},
                                    "displayText": ${text}
                                }
                            }
                        ],
                        "suggestions": ${suggestions},
                        "linkOutSuggestion": {
                            "destinationName": "Feedback",
                            "url": ${feedbackURL}
                        }
                    }
                }
            },
            "outputContexts": [
                {
                  "name": "projects/${projectID}/agent/sessions/${conversationID}/contexts/${context}",
                  "lifespanCount": 15,
                  "parameters": { 
                    "param":"value"
                   }
                }]
        }

但是，这不会更改在该上下文中指定的任何参数.我是做错了什么，还是有更好的方法使用webhook响应来更改输出上下文的参数?

However, this does nothing to change any parameters specified within that context. Am I doing something incorrectly or is there a better method of changing parameters for an output context using webhook responses?

推荐答案

只是设法解决了这个问题. 我没有尝试创建自己的输出上下文，而是操作了req.body.queryResult.outputContexts中的值.

Just managed to solve the issue. Instead of trying to create my own output context i just manipulated the values in req.body.queryResult.outputContexts.

例如: req.body.queryResult.outputContexts[0].parameters.param="value"

，然后发送带有原始outputContext的响应

and then sent the response with the original outputContext

{
            "fulfillmentText": ${textToSpeech},
            "fulfillmentMessages": [{ "text": { "text": [${text}] } }],
            "payload": {
                "google": {
                    "expectUserResponse": true,
                    "richResponse": {
                        "items": [
                            {
                                "simpleResponse": {
                                    "textToSpeech": ${textToSpeech},
                                    "displayText": ${text}
                                }
                            }
                        ],
                        "suggestions": ${suggestions},
                        "linkOutSuggestion": {
                            "destinationName": "Feedback",
                            "url": ${feedbackURL}
                        }
                    }
                }
            },
            "outputContexts": ${req.body.queryResult.outputContexts}
        }
