Google Chat 消息概览
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
本页介绍了文本消息和卡片消息之间的区别。
当 Chat 应用发送短信来传达基本信息时,这些消息会以内嵌方式显示,就像 Google Chat 中的用户撰写消息一样。如需创建包含文本以外内容的消息,或创建用户可与之互动的消息,Chat 应用可以使用卡片。
聊天应用还可以附加包含卡片的短信。为了提示用户完成多步流程(例如填写表单),Chat 应用还可以创建在新窗口中打开的卡片,作为对话框。
短信详解
在 Google Chat API 中,消息以 JSON 对象的形式表示。在消息中,文本消息表示为 text
对象。
在以下示例中,Chat 应用在软件开发者团队的聊天室中创建了一条文本消息,告知他们代码冻结期即将到来:
{
"text": "Attention <users/all>: Code freeze starts at `11:59 am` Pacific Standard Time! If you need a little more time, type `/moreTime` and I'll push the code freeze back one hour."
}
JSON 会返回以下消息:
卡片消息详解
在 Google Chat API 中,消息以 JSON 对象的形式表示。在消息中,卡片表示为 cardsV2
数组,包含以下内容:
- 一个或多个
CardWithId
对象。
- 一个
cardId
,用于标识卡片,范围限定在指定消息内。
(不同消息中的卡片可以具有相同的 ID。)
一个 card
对象,包含以下内容:
例如,以下卡片消息包含 header
、section
和 widget
对象:
以下代码表示卡片消息的 JSON:

To create messages that contain more than text, or to create\nmessages that users can interact with, Chat apps can use\n[cards](/workspace/chat/create-messages#create).\nChat apps can also append a text message with a card. To\nprompt users to finish multi-step processes such as completing a form,\nChat apps can also create cards that open in a new window as\n[dialogs](/workspace/chat/dialogs).\n\nAnatomy of a text message\n-------------------------\n\nIn the Google Chat API, messages are represented as JSON objects. Within a message,\na text message is represented as a\n[`text`](/workspace/chat/api/reference/rest/v1/spaces.messages#Message.FIELDS.text)\nobject.\n\nIn the following\nexample, a Chat app creates a text message in a space\nfor a team of software developers that a code freeze is approaching: \n\n {\n \"text\": \"Attention \u003cusers/all\u003e: Code freeze starts at `11:59 am` Pacific Standard Time!
