使用 Google Chat API 发送消息

本指南介绍如何调用 Google Chat API 的 messages.create() 方法执行以下任何操作：

  • 发送包含文本、卡片和互动微件的消息。
  • 向特定 Chat 用户私下发送消息。
  • 发起或回复消息串。
  • 为消息命名，以便在其他 Chat API 中指定 请求。

<ph type="x-smartling-placeholder">

邮件（包括任何文字或卡片）的大小上限为 32,000 字节。 如要发送超出此大小的消息，您的 Chat 扩展应用 必须改为发送多条消息。

除了调用 messages.create() 方法之外，Chat 扩展应用 可以创建和发送消息来回复用户互动，如发布 用户在将 Chat 应用添加到 空间。在响应互动时，Chat 扩展应用可以使用 消息功能的类型，包括互动对话框和链接预览 界面。为了回复用户，Chat 应用会返回 无需调用 Chat API 即可同步处理消息。学习内容 有关如何发送消息来响应互动的信息，请参阅 在 Google Chat 应用中接收和回复互动信息。

Chat 如何显示和归因使用 Chat API 创建的消息

您可以使用以下代码调用 messages.create() 方法： 应用身份验证 和用户身份验证。 Chat 对消息发送者的界定有所不同 具体取决于您使用的身份验证类型。

以 Chat 应用的身份进行身份验证时， Chat 应用发送消息。

您作为用户进行身份验证后，Chat 应用会将 。Chat 还会将 Chat 应用通过显示消息名称来发送消息。

图 2：通过用户身份验证，用户发送消息，Chat 会显示 聊天应用名称。

身份验证类型还决定了哪些消息传递功能和界面 您可以包含在消息中的名称借助应用身份验证 聊天应用可以发送包含富文本、 基于卡片的界面和交互式小部件。 由于 Chat 用户只能在消息中发送短信，因此您可以 使用用户身份验证创建邮件时仅包含文本。 详细了解消息功能 功能的详细信息，请参阅 Google Chat 消息概览。

本指南介绍了如何使用这两种身份验证类型来发送邮件 使用 Chat API。

通过应用身份验证发送消息
图 4. Chat 应用会向以下应用发送消息： 卡片和一个配件按钮

若要使用应用身份验证调用 messages.create()，您必须指定 以下字段：

  • chat.bot 授权范围。
  • Space资源 。Chat 应用必须 聊天室成员。
  • Message 要创建的资源。要定义消息的内容，您可以在 富文本 (text), 一个或多个卡片接口 (cardsV2), 或者两者兼有

您还可以选择添加以下内容：

在邮件底部添加互动微件

在本指南的第一个代码示例中， Chat 应用消息在 称为配件微件。配件微件 。您可以使用这些微件 用户可通过多种方式与您的消息互动，包括：

  • 对消息的准确性或满意度进行评分。
  • 报告消息或 Chat 应用存在的问题。
  • 打开指向相关内容（例如文档）的链接。
  • 在 Chat 应用中关闭或延后类似消息 特定时间段内的效果

如需添加配件微件，请添加 accessoryWidgets[] 字段，然后指定所需的一个或多个微件 。

下图显示了将 包含配件微件的短信，以便用户对自己的体验进行评分 使用 Chat 应用。

<ph type="x-smartling-placeholder">

    onClick: { action: {
      function: "doDownvote"
    }}
  }]}}]
}

私下发送消息

聊天应用可以私下发送消息 消息仅对聊天室中的特定用户可见。当 聊天应用会发送一条私信 会显示一个标签，通知用户相应邮件仅对他们可见。

要使用 Chat API 以私密方式发送消息，请指定 privateMessageViewer 字段。要指定用户，请将值设置为 User 资源， 代表 Chat 用户。您还可以使用 name 字段的 User 资源，如以下示例所示：

{
  text: "Hello private world!",
  privateMessageViewer: {
    name: "users/USER_ID"
  }
}

如需使用此示例，请将 USER_ID 用户的唯一 ID，例如 12345678987654321 或 hao@cymbalgroup.com。如需详细了解如何指定用户，请参阅 识别并指定 Google Chat 用户。

要以私密方式发送消息，您必须在请求中省略以下内容：

代表用户发送短信

本部分介绍了如何使用 用户身份验证。 借助用户身份验证，邮件内容只能包含文本 并且必须省略仅适用于 聊天应用，包括卡片界面和交互式微件。

通过用户身份验证发送消息
图 3. Chat 应用可通过以下应用发送短信： 。

若要使用用户身份验证调用 messages.create()，您必须指定 以下字段：

  • 授权范围 此方法支持用户身份验证。以下示例使用 chat.messages.create 范围。
  • Space资源 。通过身份验证的用户必须是 空间。
  • Message 要创建的资源。要定义消息的内容，您必须在代码中添加 text 字段。

您还可以选择添加以下内容：

  • messageId 字段，可让您 为消息命名以便在其他 API 请求中使用。
  • thread.threadKey 和 messageReplyOption 字段 发起或回复讨论帖。如果聊天室没有 使用线程处理，系统会忽略此字段。

以下代码展示了 Chat 应用如何 可以代表经过身份验证的用户在指定空间中发送短信：

在消息串中发起或回复消息

对于使用话题的聊天室： 您可以指定新消息是发起会话还是回复 现有线程

默认情况下，您使用 Chat API 创建的消息会发起新的 线程。为方便识别该会话并稍后回复，您可以指定一个 线程键：

如需创建回复现有会话的消息，请执行以下操作：

  • 在您的请求正文中，添加 thread 字段。如果已设置，您可以 指定 threadKey 创建的所有文件否则，您必须使用 name 线程。
  • 指定查询参数 messageReplyOption。

如需运行此示例，请替换以下内容：

  • THREAD_KEY：聊天室中的现有消息串键，或 来创建新线程，这是线程的唯一名称。
  • SPACE_NAME：聊天室的 ID name 字段。可通过调用 spaces.list() 方法 或者通过聊天室网址添加

为消息命名

如需在将来的 API 调用中检索或指定消息，您可以为消息命名 方法是在 messages.create() 请求中设置 messageId 字段。 通过为消息命名，您可以指定消息，而无需存储 消息的资源名称中系统分配的 ID（以 name 字段）。

例如，如需使用 get() 方法检索消息，您可以使用 资源名称指定要检索的消息。资源名称为 格式为 spaces/{space}/messages/{message}，其中 {message} 表示 系统分配的 ID 或您在创建 消息。

要命名消息，请在 messageId 字段。messageId 字段用于设置 clientAssignedMessageId Message 资源的指定字段。

您只能在创建消息时为其命名。您不能命名或 修改现有消息的自定义 ID。自定义 ID 必须符合以下要求 要求：

  • 以 client- 开头。例如，client-custom-name 是有效的自定义 但 custom-name 不是。
  • 最多包含 63 个字符，且只能包含小写字母、数字和 连字符。
  • 在聊天室中是唯一的。Chat 应用无法使用 为不同的消息使用相同的自定义 ID。

以下代码展示了 Chat 应用如何 可以代表 经过身份验证的用户：

Node.js
