對話方塊採用視窗式的資訊卡介面，即時通訊應用程式會開啟與使用者互動的介面。為協助使用者完成多步驟程序，應用程式可以開啟依序對話方塊。
對話方塊適用於多種使用者互動類型，包括：
- 收集使用者資訊
- 透過網路服務驗證使用者
- 調整即時通訊應用程式設定
本指南說明如何為 Chat 應用程式實作對話方塊。
必要條件
如要實作對話方塊並執行本指南中的範例，您必須：
Node.js
- 擁有 Google Chat 存取權的 Google Workspace 帳戶。
- Chat 應用程式。如要建構即時通訊應用程式，請按照這份快速入門導覽課程操作。
- 如果為了開啟斜線指令而開啟對話方塊，您必須為 Chat 應用程式設定斜線指令。
Apps Script
- 擁有 Google Chat 存取權的 Google Workspace 帳戶。
- Chat 應用程式。如要建構即時通訊應用程式，請按照這份快速入門導覽課程操作。
- 如果為了開啟斜線指令而開啟對話方塊，您必須為 Chat 應用程式設定斜線指令。
Python
- 擁有 Google Chat 存取權的 Google Workspace 帳戶。
- Chat 應用程式。如要建構即時通訊應用程式，請按照這份快速入門導覽課程操作。
- 如果為了開啟斜線指令而開啟對話方塊，您必須為 Chat 應用程式設定斜線指令。
對話方塊的運作方式
當使用者按一下資訊卡上的按鈕或發出斜線指令時，Chat 應用程式可以開啟與使用者互動的對話方塊。
這個對話方塊可讓使用者透過小工具輸入資訊 (例如輸入文字輸入欄位)，協助使用者互動。收集大量使用者資訊時，Chat 應用程式可以開啟連續對話方塊。
完成後，Chat 應用程式會收到使用者在對話方塊中輸入的值，格式為 JSON。藉由透過簡訊或資訊卡來回應，說明使用者已成功互動。
開啟對話方塊
即時通訊應用程式可以開啟對話方塊，以回覆使用者：
當使用者要求對話方塊時，Chat 應用程式會收到 Google Chat Event，其中：
isDialogEvent為true。DialogEventType指定使用者是否開啟對話方塊 (REQUEST_DIALOG)、點選對話方塊中的按鈕 (SUBMIT_DIALOG)，或是取消對話方塊 (CANCEL_DIALOG)。
舉例來說，當使用者開啟對話方塊時，Chat 應用程式會從 Google Chat 收到像這樣的 Event：
JSON
{
"type": enum (EventType),
"eventTime": string,
"threadKey": string,
"message": {
object (Message)
},
"user": {
object (User)
},
"space": {
object (Space)
},
"action": {
object (FormAction)
},
"configCompleteRedirectUrl": string,
"isDialogEvent": true,
"dialogEventType": "REQUEST_DIALOG",
"common": {
object (CommonEventObject)
}
}
透過 Chat 應用程式傳回 ActionResponse "type": "DIALOG" DialogAction，且內含對話方塊的 JSON 說明，即可開啟對話方塊：
JSON
{
"action_response": {
"type": "DIALOG",
"dialog_action": {
"dialog": {
"body": {
"sections": [
{
"header": "Add new contact",
"widgets": [
{
"textInput": {
"label": "Name",
"type": "SINGLE_LINE",
"name": "contactName"
}
},
{
"textInput": {
"label": "Address",
"type": "MULTIPLE_LINE",
"name": "address"
}
},
{
"decoratedText": {
"text": "Add to favorites",
"switchControl": {
"controlType": "SWITCH",
"name": "saveFavorite"
}
}
},
{
"decoratedText": {
"text": "Merge with existing contacts",
"switchControl": {
"controlType": "SWITCH",
"name": "mergeContact",
"selected": true
}
}
},
{
"buttonList": {
"buttons": [
{
"text": "Next",
"onClick": {
"action": {
"function": "openSequentialDialog"
}
}
}
]
}
}
]
}
]
}
}
}
}
}
開啟對話方塊來回應資訊卡上的按鈕
當使用者點選資訊卡中的按鈕時，您的應用程式會收到 Event，其中：
EventType為CARD_CLICKED狀態。DialogEventType為REQUEST_DIALOG狀態。
如要開啟對話方塊，請指定：
onClick.action.function做為開啟對話方塊的函式名稱。該函式必須傳回：- 「
"type": "DIALOG"」的ActionResponse。 - 包含對話方塊 JSON 說明的
DialogAction。
- 「
- 「
onClick.action.interaction」為「OPEN_DIALOG」。這個屬性會通知 Google Chat 應用程式想要開啟對話方塊。
在這個範例中，Chat 應用程式透過資訊卡回應了 MESSAGE Event，其中包含一個開啟對話方塊的按鈕：
Node.js
/**
* Responds to messages that have links whose URLs
* match URL patterns configured for link previews.
*
* @param {Object} event The event object from Chat
* API.
*
* @return {Object} Response from the Chat app
* attached to the message with the previewed link.
*/
exports.onMessage = function onMessage(req, res) {
// Store the Google Chat event as a variable.
var event = req.body;
if (req.method === "GET" || !event.message) {
res.send("Hello! This function is meant to be used in a Google Chat " +
"Space.");
}
// Responds with a card that prompts the user to add a contact
else {
res.json({
"cardsV2": [{
"cardId": "addContact",

}

});
}

if(event.type === "CARD_CLICKED") {
if (event.common.invokedFunction == "openDialog") {
res.openDialog(event);
};

將多個卡片介面串連在一起
如果使用者需要多張卡片，您可以在同一個對話方塊中傳回其他對話方塊，透過同一個對話方塊開啟新的資訊卡。
當使用者點選對話方塊中的按鈕時，應用程式會收到 Event，其中：
EventType為CARD_CLICKED狀態。DialogEventType為SUBMIT_DIALOG狀態。
由於對話方塊已開啟，因此請勿指定如同在對話資訊卡中開啟對話方塊時那樣指定 onClick.action.interaction。只傳回 onClick.action.function 做為開啟對話方塊的函式名稱。
在這個範例中，Chat 應用程式會開啟另一個對話方塊，以點選對話方塊按鈕的點擊來回應 CARD_CLICKED Event：
Node.js
// Respond to button clicks on attached cards
if(event.type === "CARD_CLICKED") {
// Open the first dialog.
if (event.common.invokedFunction == "openDialog") {
res.openDialog(event);
}
// Open the second dialog.
if (event.common.invokedFunction == "openSequentialDialog") {
res.openSequentialDialog(event);

透過對話方塊接收表單資料
當使用者點選對話方塊中的按鈕時，使用者輸入的資料會提交至 Chat 應用程式，且應用程式會收到 Event，其中：
EventType為CARD_CLICKED狀態。DialogEventType為SUBMIT_DIALOG狀態。
在 Event 中，使用者可在對話方塊中輸入的資料以 Event.common.formInputs 形式提供。圖中的鍵是指派給每個對話方塊小工具的字串 ID，值代表每個小工具的使用者輸入內容。不同的物件代表不同的輸入資料類型。舉例來說，Event.common.formInputs.stringInputs 代表字串輸入。
使用者提交對話方塊後，Chat 應用程式會從 Google Chat 收到像這樣的 Event：
JSON
{
"type": enum (EventType),
"eventTime": string,
"threadKey": string,
"message": {
object (Message)
},
"user": {
object (User)
},
"space": {
object (Space)
},
"action": {
object (FormAction)
},
"configCompleteRedirectUrl": string,
// Indicates that this event is dialog-related.
"isDialogEvent": true,
// Indicates that a user clicked a button, and all data
// they entered in the dialog is included in Event.common.formInputs.
"dialogEventType": "SUBMIT_DIALOG",
"common": {
"userLocale": string,
"hostApp": enum (HostApp),
"platform": enum (Platform),
"timeZone": {
object (TimeZone)
},
// Represents user data entered in a dialog
"formInputs": {
// Represents string data entered in a dialog, like text input fields
// and check boxes
"stringInputs": {
// An array of strings entered by the user in a dialog.
"value": [
string
]
}
},
"parameters": {
string: string,
...
},
"invokedFunction": string
}
}
您的應用程式可在 event.common.formInputs.NAME.stringInputs.value[0] 存取第一個使用者輸入的值，其中 NAME 是 TextInput 小工具的 name 欄位。
收到對話方塊表單資料後，Chat 應用程式應透過確認回條或傳回錯誤的方式回應，兩者皆會傳回 ActionResponse：
- 如要確認收到成功的收據，請回覆含有
"actionStatus": "OK"的ActionResponse。 - 如要傳回錯誤，請回應含有
"actionStatus": "ERROR MESSAGE"的ActionResponse。
以下範例會檢查是否有「name」值。如果沒有，應用程式會傳回錯誤。如果檔案存在，應用程式會確認收到表單資料，並關閉對話方塊。
