Twilio:将呼叫转发到 Twilio 中的流程
我想在 Flex 中的代理挂断后将呼叫转发到 Studio Flow,以便可以为用户播放 CSAT 调查。 我创建了一个调用 Twilio 内部函数的插件,但转发完成后出现“错误 - 11200”。
我替换了挂断操作,以便它将调用重定向到 twilio 中的函数。该函数应该将调用发送到将播放调查的流程。我怀疑问题与身份验证有关,但我找不到太多相关信息。
我对 twilio 相当陌生,所以任何帮助将不胜感激
这是插件调用该函数的部分:
flex.Actions.replaceAction("HangupCall", (payload) => {
console.log('task attributes: ' + JSON.stringify(payload.task.attributes));
if (payload.task.attributes.direction === "inbound") {
// Describe the body of your request
const body = {
callSid: payload.task.attributes.call_sid,
callerId: payload.task.attributes.from,
destination: '+18xxxxxxxx',
Token: manager.store.getState().flex.session.ssoTokenPayload.token
};
// Set up the HTTP options for your request
const options = {
method: 'POST',
body: new URLSearchParams(body),
headers: {
'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
}
};
// Make the network request using the Fetch API
fetch('https://TWILIO INSTANCE.twil.io/TransferUtil', options)
.then(resp => resp.json())
.then(data => console.log(data));
} else {
original(payload);
}
});
这是 twilio 中的函数:
const TokenValidator = require('twilio-flex-token-validator').functionValidator;
exports.handler = TokenValidator(async function(context, event, callback) {
const response = new Twilio.Response();
response.appendHeader('Access-Control-Allow-Origin', '*');
response.appendHeader('Access-Control-Allow-Methods', 'OPTIONS, POST, GET');
response.appendHeader('Access-Control-Allow-Headers', 'Content-Type');
response.appendHeader('Content-Type', 'application/json');
const client = require('twilio')();
const callSid = event.callSid;
const callerId = event.callerId;
const destination = event.destination;
console.log('Call Sid:', callSid);
console.log('Transfer call from:', callerId, 'to:', destination);
try {
let url = 'https://studio.twilio.com/v2/Flows/FWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Executions';
let call = await client.calls(callSid).update({method: 'POST', url: encodeURI(url)});
console.log(JSON.stringify(call));
response.appendHeader('Content-Type', 'application/json');
response.setBody(call);
callback(null, response);
}
catch (err) {
response.appendHeader('Content-Type', 'plain/text');
response.setBody(err.message);
console.log(err.message);
response.setStatusCode(500);
callback(null, response);
}
});
编辑: 在错误日志中,我得到以下信息:
I want to fordward a call to a Studio Flow after the agent in flex hangs up so a CSAT survey can play for the user.
I created a plugin that calls a function inside Twilio but there is a "Error - 11200" after the forwarding is done.
I replaced the hang up action so it redirects the call to a function in twilio. The function is supossed to send the call to a flow that will play the survey. I suspect the problem has to do with authentication but I can't find much about it.
I'm fairly new to twilio, so any help will be greatly appreciated
This is the part of the plugin that calls the function:
flex.Actions.replaceAction("HangupCall", (payload) => {
console.log('task attributes: ' + JSON.stringify(payload.task.attributes));
if (payload.task.attributes.direction === "inbound") {
// Describe the body of your request
const body = {
callSid: payload.task.attributes.call_sid,
callerId: payload.task.attributes.from,
destination: '+18xxxxxxxx',
Token: manager.store.getState().flex.session.ssoTokenPayload.token
};
// Set up the HTTP options for your request
const options = {
method: 'POST',
body: new URLSearchParams(body),
headers: {
'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
}
};
// Make the network request using the Fetch API
fetch('https://TWILIO INSTANCE.twil.io/TransferUtil', options)
.then(resp => resp.json())
.then(data => console.log(data));
} else {
original(payload);
}
});
And this is the function in twilio:
const TokenValidator = require('twilio-flex-token-validator').functionValidator;
exports.handler = TokenValidator(async function(context, event, callback) {
const response = new Twilio.Response();
response.appendHeader('Access-Control-Allow-Origin', '*');
response.appendHeader('Access-Control-Allow-Methods', 'OPTIONS, POST, GET');
response.appendHeader('Access-Control-Allow-Headers', 'Content-Type');
response.appendHeader('Content-Type', 'application/json');
const client = require('twilio')();
const callSid = event.callSid;
const callerId = event.callerId;
const destination = event.destination;
console.log('Call Sid:', callSid);
console.log('Transfer call from:', callerId, 'to:', destination);
try {
let url = 'https://studio.twilio.com/v2/Flows/FWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Executions';
let call = await client.calls(callSid).update({method: 'POST', url: encodeURI(url)});
console.log(JSON.stringify(call));
response.appendHeader('Content-Type', 'application/json');
response.setBody(call);
callback(null, response);
}
catch (err) {
response.appendHeader('Content-Type', 'plain/text');
response.setBody(err.message);
console.log(err.message);
response.setStatusCode(500);
callback(null, response);
}
});

呃,我读错了错误。该函数没有任何问题,错误来自尝试向 URL 发出 Webhook 请求的调用
https://studio.twilio.com/v2/Flows/FWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Executions
。这是 REST API 触发器,需要使用您的帐户凭据或 API 密钥以与任何其他 API 请求相同的方式进行请求。您应该将该 URL 设置为 Webhook 触发器 URL,该 URL 类似于
https://webhooks.twilio.com/v1/Accounts/${ACCOUNT_SID}/Flows/${FLOW_SID}
。然后,调用将能够将其请求作为正常 Webhook 流程的一部分。Argh, I read the error wrong. There isn't anything wrong with the Function, the error is coming from the call trying to make a webhook request to the URL
https://studio.twilio.com/v2/Flows/FWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Executions
. That's the REST API trigger and needs to be requested in the same way as any other API request using your account credentials or API keys.You should set that URL to the webhook trigger URL, which looks like
https://webhooks.twilio.com/v1/Accounts/${ACCOUNT_SID}/Flows/${FLOW_SID}
. Then the call will be able to request it as part of a normal webhook flow.
