发送消息

您收到用户发来的消息后，可以将回复发送至 继续对话。您可以在 30 天内向用户发送消息 用户的上一条消息。

代理通过发送和接收消息与用户通信。发送 消息，则您的代理会向 Business Messages 发送消息请求。

注意 ：如果您要使用命令行进行 API 调用，请安装 oauth 2l。

如需发送消息，请向 Business Messages API 发送 HTTP POST 请求 包括

• 唯一邮件 ID
• 对话 ID
• 邮件内容

Business Messages API 将消息发送给用户时，会返回 200 OK。如果您的消息中缺少必需的值，则 API 会返回 400 错误。如果消息使用的凭据无效，API 会返回 401 错误。

使用 Business Communications 开发者控制台日志 页面 调试邮件递送问题。

后备策略

如果用户的设备不支持您尝试发送的消息，例如 用户不支持建议的回复，则该 API 会返回 400 (FAILED PRECONDITION) 错误。不过，您可以通过 为发送的每条信息指定 fallback 文本。如果您指定 fallback 那么即使用户的设备未这样做，该 API 仍会返回 200 OK 响应 支持消息类型。

如果用户收到的消息说其设备不支持，但提供了 fallback文字，其设备会改为显示fallback文字。这个 这让您能以主动的方式继续对话， 中断对话进行，或者需要花费额外的时间来处理 400 (FAILED PRECONDITION) 错误并识别备选消息。

任何给定消息的 fallback 文本都应反映消息的功能。 例如，

• 对于包含建议回复或操作的邮件，请在邮件中添加 fallback 文字，并包含有关用户可以选择的选项的指南 继续对话。
• 对于复合搜索卡或轮播界面，请在 fallback文字，并包含指向图片或网站的链接。

如需在 fallback 文本中插入换行符，请使用 \n 或 \r\n。

测试后备文字

在发布代理之前，您可以测试后备文字在 通过发送消息，将网址参数 forceFallback 设置为 true。当您强制使用后备文本时，对话将忽略主要 消息内容（以下示例中的文本和开放网址建议）和 则会显示后备文字。

注意 ：forceFallback 网址参数不适用于已发布的代理。

议员

当代理发送消息时，您需要指定一位代表：人工或 组成消息的自动化操作。Business Messages 支持HUMAN和 BOT代表。

当采用任何类型的自动化机制撰写消息时，请指定 BOT 代表； 自动化操作是不是自动回复程序，可以告诉用户他们所处的 队列是一个复杂的自然语言理解代理， 用户详细信息或两者之间的任何信息系统会显示与 BOT 代表的消息 以及一个小图标 可帮助设置对他们可能的互动类型有一定的预期 互动。

仅在人工客服撰写消息时指定 HUMAN 代表。 在 HUMAN 代表发送任何消息之前，请先发送 REPRESENTATIVE_JOINED 事件 用户知道他们可以发送更加自由或复杂的讯息。在您发送 HUMAN 代表的最后一条消息，发送 REPRESENTATIVE_LEFT 事件 再次为用户设定恰当的预期

例如，如果用户开始与您的代理对话， 自动发送消息，告知他们应该会在两分钟内收到人工客服 该消息应由 BOT 代表发送。在 人工客服加入，发送 REPRESENTATIVE_JOINED 事件。来自 的所有邮件 人工客服应标记为来自 HUMAN 代表。当 人工客服退出对话，发送 REPRESENTATIVE_LEFT 事件。全部 后续消息应由BOT代表发出，除非有其他正在进行的直播 让客服人员加入对话。

注意 ：如果您使用 Dialogflow 启用自动响应 集成， 您仍负责处理人工客服请求， 发送相应的 REPRESENTATIVE_JOINED 和 REPRESENTATIVE_LEFT 事件、 以及向HUMAN代表发送邮件。

请参阅从聊天机器人转到实时会话 代理 获取在 BOT 和 HUMAN 之间转换的示例对话和代码 代表。

无论代表是BOT还是HUMAN，您都可以指定一位代表 显示名称和头像用户可以看到显示名称和头像。 头像图片的尺寸必须为 1024x1024 像素，不能超过 50 KB，并且必须指定 公开的网址。如果您不提供头像图片，代理的 代表的头像使用徽标。

注意 ：头像图片不支持个人信息，例如对 照片中的代表。使用不会识别个人身份的图片，例如 图标、徽标或虚构插图将头像图片用于 消息，则该图片无法修改或删除。

文本

最简单的消息是由文本组成的。短信最适合 来传递信息，而无需视觉、复杂互动或 响应。

示例

以下代码会发送一条简单的短信。如需了解参考信息，请参阅 conversations.messages.create。

建议操作

“建议操作”功能可利用原生 自己设备的功能当用户点按建议的操作时，您的 代理会收到一条包含操作文本和回传数据的消息。

建议的操作不得超过 25 个字符，且消息不得超过 共 13 条建议。

注意 ：代理不应仅依赖于建议的操作来触发 用户行为如果用户的客户端版本已过时，该客户端 因此可能无法显示建议的操作。

如需了解格式设置和值选项，请参阅 conversations.messages.create 和 SuggestedAction。

打开网址操作

对于“打开网址”操作，代理会推荐一个网址供用户打开。如果 将应用注册为网址的默认处理程序，系统会改为打开该应用，并且 该操作的图标是应用的图标。打开网址操作仅支持网址 对于 HTTP 和 HTTPS 协议，其他协议（如 mailto）不得 支持。

以下代码使用“打开网址”操作发送文本。关于格式和值 选项，请参阅 OpenUrlAction。

复合信息卡

当您需要发送大量相关信息、媒体或建议时， 应发送复合信息卡。借助复合搜索卡，代理可以向 单条消息中提供的信息。

复合信息卡可包含以下项目：

• 媒体（JPG、JPEG 或 PNG，最大 5 MB）
• 媒体缩略图（JPG、JPEG 或 PNG，最大 25 KB）
• 标题（最多 200 个字符）
• 广告内容描述（最多 2000 个字符）
• 建议的回复列表 和建议的操作 （最多 4 个）

复合信息卡可以包含列出的任意或所有项目，但复合信息卡必须包含 至少需要有媒体或标题才有效。一张复合信息卡最多可包含四张 建议的操作和建议的回复。

您的代理可以在一个复合信息卡中同时发送多张复合信息卡 轮播界面。

示例

以下代码会发送包含图片和建议的回复的复合信息卡。对于 格式和值选项，请参阅 conversations.messages.create 和 RichCard。
