Google Chat 訊息總覽
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
本頁面說明文字訊息和資訊卡訊息之間的差異。
當 Chat 應用程式傳送簡訊來傳達基本資訊時,訊息會內嵌顯示,就像 Google Chat 使用者撰寫訊息一樣。如要建立包含文字以外內容的訊息,或建立使用者可互動的訊息,Chat 應用程式可以使用資訊卡。即時通訊應用程式也可以在文字訊息中附加卡片。如要提示使用者完成多步驟程序 (例如填寫表單),Chat 應用程式也可以建立資訊卡,並以對話方塊的形式在新視窗中開啟。
簡訊剖析
在 Google Chat API 中,訊息會以 JSON 物件表示。在訊息中,文字訊息會以 text
物件表示。
在下列範例中,Chat 應用程式會在軟體開發人員團隊的聊天室中建立訊息,通知他們程式碼凍結期即將到來:
{
"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 會傳回下列訊息:
卡片訊息結構
在 Google Chat API 中,訊息會以 JSON 物件表示。在訊息中,資訊卡會以 cardsV2
陣列表示,並包含下列項目:
- 一或多個
CardWithId
物件。
cardId
,用於識別資訊卡,並限定在特定訊息內。(不同訊息中的資訊卡可以有相同的 ID)。
card
物件,包含下列項目:
舉例來說,下列資訊卡訊息包含 header
、section
和 widget
物件:
下列程式碼代表訊息的 JSON 格式:

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!
