Dialogflow中的自定义有效载荷

Question

我试着在Dialogflow中用履行(nodejs)发送自定义的payload。

我的动机是发送链接和文本作为对网页的响应。

我的示例代码供参考。

  const response = {
      messages: [
        {
          payload: {
            messages: [
              {
                speech: 'here are some quick links for your convenience.',
                linkmessage: [{
                  message: 'google',
                  link: 'www.google.com'
                }, {
                  message: 'yahoo',
                  link: 'www.yahoo.co.in'
                }],
                button: [{
                  buttonname: 'more page'
                }]
              }
            ]
          }
        }
      ]
    };
    agent.add(new Payload(agent.UNSPECIFIED, response, { rawPayload: true, sendAsMessage: true}));

这里我得到的响应是：

{
    "fulfillment": {
      "speech": "",
      "messages": [
        {
          "lang": "en",
          "type": 0,
          "speech": ""
        }
      ],
      "data": {
        "null": {
          "messages": [
            {
              "payload": {
                "messages": [
                  {
                    "speech": "here are some quick links for your convenience.",
                    "linkmessage": [{
                      "message": "google",
                      "link": "www.google.com"
                    }, {
                      "message": "yahoo",
                      "link": "www.yahoo.co.in"
                    }],
                    "button": [{
                      "buttonname": "more page"
                    }]
                  }
                ]
              }
            }
          ]
        }
      }
    }

在这里，你可以看到在响应中，我得到"无效"对象被附加在响应的数据对象里面。

有谁能帮我删除这个 无效 对话流响应中的对象，以及其他任何从履行nodejs中发送自定义payload的选项。

Answer 1

function update() {
const response = {
      messages: [
        {
          payload: {
            messages: [
              {
                speech: 'here are some quick links for your convenience.',
                linkmessage: [{
                  message: 'google',
                  link: 'www.google.com'
                }, {
                  message: 'yahoo',
                  link: 'www.yahoo.co.in'
                }],
                button: [{
                  buttonname: 'more page'
                }]
              }
            ]
          }
        }
      ]
    };
    agent.add(new Payload(agent.UNSPECIFIED, response, { rawPayload: true, sendAsMessage: true}));
}

在这个函数中需要添加参数为agent，这样你就可以得到非 "null "的对象。

需要更新参考编码。

function update(agent) {
const response = {
      messages: [
        {
          payload: {
            messages: [
              {
                speech: 'here are some quick links for your convenience.',
                linkmessage: [{
                  message: 'google',
                  link: 'www.google.com'
                }, {
                  message: 'yahoo',
                  link: 'www.yahoo.co.in'
                }],
                button: [{
                  buttonname: 'more page'
                }]
              }
            ]
          }
        }
      ]
    };
    agent.add(new Payload(agent.UNSPECIFIED, response, { rawPayload: true, sendAsMessage: true}));
}
