Question

我正在尝试访问卡片json值，但无济于事。

在我的情景中，我正在向机器人询问“伦敦的天气”，并回复说“它目前在伦敦是9摄氏度”。通过webhook。

这是正确和动态的。

但是，我也试图将值传递给卡片。

在json的回复中，我确实得到了这张卡

              ]

  },
  "status": {
    "code": 200,
    "errorType": "success",
    "webhookTimedOut": false
  },

  "sessionId": "REMOVED"
}

使用data.result.fulfillment.speech访问语音值可以正常工作。

但是，使用data.result.fulfillment.data.items.basicCard.image.url时，它不起作用。如果我上升几个级别，我会得到：

[object Object]

感谢您的帮助。

h1:nth-of-type(0) + * { display: block; }属性是列表而不是对象。因此，您必须使用数字索引来检索数据。在您提供的示例中，<div class="dropdown"> <h1>Title 1</h1> <ul> <li>Item 1.1</li> <li>Item 2.2</li> <li>Item 3.3</li> </ul> <h1>Title 2</h1> <ul> <li>Item 2.1</li> <li>Item 2.2</li> <li>Item 2.3</li> </ul> <h1>Title 3</h1> <ul> <li>Item 3.1</li> <li>Item 3.2</li> <li>Item 3.3</li> </ul> </div>对象的索引是第二个，因此您的代码应如下所示：

.dropdown { text-align: left; color: #00F; background-color: transparent; } h1 { display: inline-block; border-top: 1px solid #000; width: 290px !important; color: #F00; font-weight: 500; border-left: 0; padding-left: 0; margin-left: 0; padding-top: 13px; line-height: 30px !important; } h1 a, h1 a:visited { color: #FFFDFD; } h1:nth-of-type(0) + * { display: block; } h1 + * { display: none; } h1:hover + *, h1 + *:hover { display: block; }

请注意items之后的basicCard。

请记住，如果此列表的顺序发生变化，您可能不再检索data.result.fulfillment.data.items[1].basicCard.image.url对象，因此您可能需要添加一些检查以确保您正在检索所需的数据。 / p>
