如何在对话更新活动中获取语言环境? [英] How do I get the locale in conversationUpdate activity?
问题描述
我想对根据其区域设置添加的每个成员实施欢迎消息.代码如下:
I would like to implement a welcome message for every members added based on their locale. The code is as following:
if (message.Type == ActivityTypes.ConversationUpdate)
{
// some code...
if (message.Locale == "en-us")
{
var reply = message.CreateReply("Hello world");
}
else
{
// some code...
}
// some code...
}
Strangely, the locale is null even though I've set the locale both when I test it using bot emulator and BotFramework-WebChat. The locale property is working fine when messages is received.
在对话更新活动期间，有什么方法可以获取语言环境?
Is there any way I could get the locale during conversationUpdate activity?
提前谢谢！
推荐答案
一种在第一次输入之前获取用户语言的解决方案是使用Webchat的backchannel功能.这样，我们就可以以隐藏方式将信息推送到我们的机器人，例如提供区域设置或自定义ID.
One solution to get the language of the user before his 1st input is to use the backchannel feature of the Webchat. This allows us to push information to our bot in a hidden way, to provide locale or a custom id for example.
您将在GitHub帐户此处找到该演示.

特别是，这是您的Webchat集成示例，该集成最后通过postActivity将事件发送到bot，这是从Microsoft的Webchat GitHub描述中的示例创建的:
In particular, here is the sample of integration of your webchat sending the event to the bot at the end with a postActivity, created from the samples on Microsoft's Webchat GitHub description:
<!DOCTYPE html>
<html>
<head>
<link href="https://cdn.botframework.com/botframework-webchat/latest/botchat.css" rel="stylesheet" />
</head>
<body>
<div id="bot" />
<script src="https://cdn.botframework.com/botframework-webchat/latest/botchat.js"></script>
<script>
// Get parameters from query
const params = BotChat.queryParams(location.search);
// Language definition
var chatLocale = params['locale'] || window.navigator.language;
// Connection settings
const botConnectionSettings = new BotChat.DirectLine({
domain: params['domain'],
secret: 'YOUR_SECRET',
webSocket: params['webSocket'] && params['webSocket'] === 'true' // defaults to true
});
// Webchat init
BotChat.App({
botConnection: botConnectionSettings,
user: { id: 'userid' },
bot: { id: 'botid' },
locale: chatLocale,
resize: 'detect'
}, document.getElementById('bot'));
// Send message to provide language of user
botConnectionSettings.postActivity({
type: 'event',
from: { id: 'userid' },
locale: chatLocale,
name: 'localeSelectionEvent',
value: chatLocale
}).subscribe(function (id) { console.log('event language "' + chatLocale + '" selection sent'); });
</script>
</body>
</html>
我添加了一个控制台事件来显示发布的活动.
I added a console event to show the activity posted.
该事件随后被机器人的MessageController接收并处理:
This event is then received by the bot's MessageController and treated:
[BotAuthentication]
public class MessagesController : ApiController
{
/// <summary>
/// POST: api/Messages
/// Receive a message from a user and reply to it
/// </summary>
public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
// DEMO PURPOSE: echo all incoming activities
Activity reply = activity.CreateReply(Newtonsoft.Json.JsonConvert.SerializeObject(activity, Newtonsoft.Json.Formatting.None));
var connector = new ConnectorClient(new Uri(activity.ServiceUrl));
connector.Conversations.SendToConversation(reply);
// Process each activity
if (activity.Type == ActivityTypes.Message)
{
await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
}
// Webchat: getting an "event" activity for our js code
else if (activity.Type == ActivityTypes.Event && activity.ChannelId == "webchat")
{
var receivedEvent = activity.AsEventActivity();
if ("localeSelectionEvent".Equals(receivedEvent.Name, StringComparison.InvariantCultureIgnoreCase))
{
await EchoLocaleAsync(activity, activity.Locale);
}
}
// Sample for emulator, to debug locales
else if (activity.Type == ActivityTypes.ConversationUpdate && activity.ChannelId == "emulator")
{
foreach (var userAdded in activity.MembersAdded)
{
if (userAdded.Id == activity.From.Id)
{
await EchoLocaleAsync(activity, "fr-FR");
}
}
}
var response = Request.CreateResponse(HttpStatusCode.OK);
return response;
}
private async Task EchoLocaleAsync(Activity activity, string inputLocale)
{
Activity reply = activity.CreateReply($"User locale is {inputLocale}, you should use this language for further treatment");
var connector = new ConnectorClient(new Uri(activity.ServiceUrl));
await connector.Conversations.SendToConversationAsync(reply);
}
}
