当我使用收据卡时，频道线路和信使上是否有消息"Sorry, it looks like something went wrong."

Question

我创建了一个机器人并使用收据代码来显示我的摘要结果。在测试并部署到网络聊天频道时，它没有问题，但是当我将机器人添加到线路频道和信使频道时，我收到此消息"对不起，看起来出了点问题。我检查了我的代码，知道当我使用收据卡时发生了问题。

我的代码(在确认预订步骤异步时出现问题(

Messenger 正式支持收据卡，但由于通道连接器错误，它们无法正常工作。我已经在内部提交了该错误。同时，一种解决方法是使用Facebook Messenger的收据模板，并将Messenger平台模板作为频道数据发送。

在 Node.js 中发送收据卡的简单示例：

this.onMessage(async context => {
await context.sendActivity({
channelData: {
'attachment': {
'type': 'template',
'payload': {
'template_type': 'receipt',
'recipient_name': 'Stephane Crozatier',
'order_number': '12345678902',
'currency': 'USD',
'payment_method': 'Visa 2345',        
'order_url': 'http://petersapparel.parseapp.com/order?order_id=123456',
'timestamp': '1428444852',         
'address': {
'street_1': '1 Hacker Way',
'street_2': '',
'city': 'Menlo Park',
'postal_code': '94025',
'state': 'CA',
'country': 'US'
},
'summary': {
'subtotal': 75.00,
'shipping_cost': 4.95,
'total_tax': 6.19,
'total_cost': 56.14
},
'adjustments': [
{
'name': 'New Customer Discount',
'amount': 20
},
{
'name': '$10 Off Coupon',
'amount': 10
}
],
'elements': [
{
'title': 'Classic White T-Shirt',
'subtitle': '100% Soft and Luxurious Cotton',
'quantity': 2,
'price': 50,
'currency': 'USD',
'image_url': 'http://petersapparel.parseapp.com/img/whiteshirt.png'
},
{
'title': 'Classic Gray T-Shirt',
'subtitle': '100% Soft and Luxurious Cotton',
'quantity': 1,
'price': 25,
'currency': 'USD',
'image_url': 'http://petersapparel.parseapp.com/img/grayshirt.png'
}
]
}
}
}
});
});

若要创建实现特定于 LINE 的消息类型的消息，请将活动对象的通道数据属性设置为指定 LINE 消息类型和操作类型的 JSON 对象。这将指导您了解如何将 channelData 属性用于特定于 LINE 的消息。

希望这有帮助。
