我已经按照博客文章Twilio WhatsApp API and Flex in Minutes中所述设置了项目。
我遵循了说明,即使在两个不同的帐户上重复两次该过程之后,(通过沙箱)发送邮件时,也会出现以下错误:
cvc-complex-type.2.4.a:发现无效的内容(从元素'Enqueue'开始)。预期为“ {Sms,消息,重定向}”之一。
该任务未在Flex中显示。
我尝试检查WhatsApp发送的内容与SMS到达时发送的内容。这是一个简单的函数关于trigger.message
的SMS的内容:
{
EventType=onMessageSent,
InstanceSid=IS5aa457db5a2d44049c95f2d0b2699f56,
Attributes={\"proxied\":true},
DateCreated=2019-01-16T12:37:43.664Z,
Index=3,
From=sms_g13aggbhlwpgk7tbah3llj2kyjpsvvju,
MessageSid=IM9123e909eeda41ac92890201a6c3f1b4,
Source=API,
AccountSid=ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,
ChannelSid=CHbc79143368db4680a66c6c504103619f,
RetryCount=0,
ClientIdentity=sms_g13aggbhlwpgk7tbah3llj2kyjpsvvju,
WebhookType=studio,
To=CHbc79143368db4680a66c6c504103619f,
Body=Test Message,
ChannelAttributes={
status=ACTIVE,
forwarding=true,
serviceNumber=sms_g13aggbhlwpgk7tbah3llj2kyjpsvvju,
twilioNumber=+1228xxxxxxx,
from=+44798xxxxxxx,
channel_type=sms,
proxySession=KC1be96a19ed42aca39f9b6a9f06c26997
},
WebhookSid=WHcfc83a43a7c2424693fd0053b8b00a01
}
这是WhatsApp消息显示的内容:
{
ApiVersion=2010-04-01,
SmsSid=SMb44cfdb4854c41e9ee255032a5449199,
SmsStatus=received,
SmsMessageSid=SMb44cfdb4854c41e9ee255032a5449199,
NumSegments=1,
From=whatsapp:+44798xxxxxxx,
To=whatsapp:+1228xxxxxxx,
MessageSid=SMb44cfdb4854c41e9ee255032a5449199,
Body=Test Message,
AccountSid=ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,
NumMedia=0
}
如您所见,ChannelAttributes
和ChannelSid
丢失了,而这正是Flex所使用的。
然后我尝试使用一个函数转换响应:
exports.handler = function(context, event, callback) {
let response;
if (!event.message.ChannelAttributes) {
response = {
name: event.message.From,
channelType: 'sms',
channelSid: 'CHbc79143368db4680a66c6c504103619f'
};
}
else {
response = {
name: "WhatsApp_" + event.message.ChannelAttributes.from,
channelType: event.message.ChannelAttributes.channel_type,
channelSid: event.message.ChannelSid
};
}
const twilioResponse = new Twilio.Response();
twilioResponse.setStatusCode(200);
twilioResponse.appendHeader('Content-Type', 'application/json');
twilioResponse.setBody(response);
callback(null, twilioResponse);
};
并在Studio中分配属性,例如:
{
"name":"{{widgets.MyFunction.body.name}}",
"channelType":"{{widgets.MyFunction.body.channelType}}",
"channelSid":"{{widgets.MyFunction.body.channelSid}}"
}
不幸的是,这显示了相同的错误。
