如何使用Directline Webchat重新加载Web应用程序?
或者,在Directline网络聊天收到Bot的回复后,有没有办法调用Javascript函数?
答案 0 :(得分:2)
您可以使用WebChat控件的BackChannel:
const user = {
id: 'userid',
name: 'username'
};
const bot = {
id: 'botid',
name: 'botname'
};
const botConnection = new BotChat.DirectLine({
secret: 'SECRET'
});
BotChat.App({
bot: bot,
botConnection: botConnection,
user: user
}, document.getElementById('BotChatGoesHere'));
botConnection.activity$
.filter(function (activity) {
return activity.type === 'event' && activity.name === 'changeBackground';
})
.subscribe(function (activity) {
console.log('"changeBackground" received with value: ' + activity.value);
changeBackgroundColor(activity.value);
});
function changeBackgroundColor(newColor) {
document.body.style.backgroundColor = newColor;
}
此示例显示机器人如何向WebChat发送 changeBackground 事件并更改页面的backgroundColor。

您可以发送reloadPage事件并在javascript中调用location.reload(),而不是changeBackground事件。
