如何解决"系统：错误：无效令牌"在Nexmo Vonage SDK中更改为同一帐户中的新应用程序

Question

我在服务器上使用"@vonage/server-sdk": "2.10.7-beta-2"包在Vonage中创建用户。为了创建用户，我使用了这个API

const Vonage = require('@vonage/server-sdk');
const v = new Vonage({
apiKey: config.voipConfig.key,
apiSecret: config.voipConfig.secret,
applicationId: config.voipConfig.appId,
privateKey: config.voipConfig.privateKeyPath
};
v.users.create({
"name": payload.username,
"display_name": payload.displayName
}, (error: any, result: any) => {
});

一切都很好。但是，当我在vonage帐户中创建一个新的应用程序并使用新的配置时，它开始抛出以下错误

{
description: 'You did not provide a valid token. Please provide a valid token.',
code: 'system:error:invalid-token'
}

我已经检查了很多次细节，不确定出了什么问题。新凭据来自全新的帐户。

任何帮助都将不胜感激。

看起来您正在使用Vonage Conversations API创建用户。在良好的实践中，我们通常使用dotenv来存储我们的.env变量。如果您使用的是公共github repo，请记住将*.env添加到.gitignore中。

npm install dotenv

// .env
API_KEY=
API_SECRET=
APPLICATION_ID=
APPLICATION_PRIVATE_KEY_PATH=
TO_NUMBER=<YOUR CELL NUMBER>
VIRTUAL_NUMBER=<VONAGE VIRTUAL NUMBER>
NGROK_URL=https://<URL>.ngrok.io

用于测试目的。你能用下面的代码段打外呼吗？这将考验你的资质。

确保将private.key存储在与.env和outbound-call.js相同的目录中

// outbound-call.js 
require("dotenv").config();
const API_KEY = process.env.API_KEY;
const API_SECRET = process.env.API_SECRET;
const APPLICATION_ID = process.env.APPLICATION_ID;
const APPLICATION_PRIVATE_KEY_PATH = process.env.APPLICATION_PRIVATE_KEY_PATH;
const TO_NUMBER = process.env.TO_NUMBER;
const VIRTUAL_NUMBER = process.env.VIRTUAL_NUMBER;
if (!API_KEY || !API_SECRET) {
console.log("🔥 API_KEY or API_SECRET missing");
process.exit(1);
}
if (!APPLICATION_ID || !APPLICATION_PRIVATE_KEY_PATH) {
console.log("🔥 APPLICATION_ID or APPLICATION_PRIVATE_KEY_PATH missing");
process.exit(1);
}
if (!TO_NUMBER || !VIRTUAL_NUMBER) {
console.log("🔥 TO_NUMBER or VIRTUAL_NUMBER missing");
process.exit(1);
}
const Vonage = require("@vonage/server-sdk");
const vonage = new Vonage({
apiKey: API_KEY,
apiSecret: API_SECRET,
applicationId: APPLICATION_ID,
privateKey: APPLICATION_PRIVATE_KEY_PATH,
});
vonage.calls.create({
to: [
{
type: "phone",
number: process.env.TO_NUMBER,
},
],
from: {
type: "phone",
number: process.env.VIRTUAL_NUMBER,
},
ncco: [
{
action: "talk",
text: "This is a text to speech call from Vonage",
},
],
});

要测试Conversations API，您需要为Vonage应用程序启用Voice并设置answerWebhook。我也使用NGROK，所以它应该是这样的。https://<URL>.ngrok.io/webhooks/answer

当使用Conversations API时，我通常会这样做：

1. 创建对话
2. 创建用户
3. 创建成员

并将其放入/webhooks/answer

//server.js
require('dotenv').config();
let express = require('express');
let cookieParser = require('cookie-parser');
let logger = require('morgan');
let app = express();
let port = 5001;
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static('public'));
const NGROK_URL = process.env.NGROK_URL;
const Vonage = require('@vonage/server-sdk');
const vonage = new Vonage({
apiKey: process.env.API_KEY,
apiSecret: process.env.API_SECRET,
applicationId: process.env.APPLICATION_ID,
privateKey: process.env.APPLICATION_PRIVATE_KEY_PATH
});
app.post('/webhooks/answer', async (req, res) => {
console.log('🚚  answer', req.body);
let result = req.body;
const createCallConversationPromise = (ConvName, ConvDisplayName) => new Promise((resolve, reject) => {
vonage.conversations.create({
"name": ConvName,
"display_name": ConvDisplayName,
}, (error, result) => error ? reject(error) : resolve(result));
});
const createCallUserPromise = (Name, DisplayName) => new Promise((resolve, reject) => {
vonage.users.create({
name: Name,
display_name: DisplayName,
}, (error, result) => error ? reject(error) : resolve(result));
});
const createCallMemberPromise = (ConvId, UserId) => {
vonage.conversations.members.create(ConvId, {
"action": "join", 
"user_id": UserId, 
"channel": {
"type": "app"
} 
}, (error, result) => {
if(error) {
console.log('n🔥 Error Creating Member', error);
}
else {
console.log('n✅ Created Member with ConvId', ConvId, 'and UserId',UserId)
console.log(result);
}
})
};
try {
let ConvName = result.from + result.to + result.conversation_uuid;
console.log('n✅ ConvName', ConvName);
let ConvDisplayName = result.from + result.to + result.conversation_uuid;
const conversation = await createCallConversationPromise(ConvName, ConvDisplayName);
process.env.CONVERSATION_ID = conversation.id;
console.log('n✅ CONVERSATION_ID', process.env.CONVERSATION_ID);
let Name = result.from + result.conversation_uuid;
let DisplayName = result.from;
const callUser = await createCallUserPromise(Name, DisplayName);
console.log('n✅ UserId', callUser.id)
let ConvId = conversation.id;
let UserId = callUser.id;
const memberUser = await createCallMemberPromise(ConvId, UserId);
let ncco = [
{
action: "talk",
text: "<speak><lang xml:lang='en-GB'>Welcome to Vonage Development inbound call testing</lang></speak>",
voiceName: "Emma"
},
];
res.json(ncco);

} catch (error) {
console.log("🔥 Error", error);
let ncco = [
{
"action": "talk",
"text": "<speak><lang xml:lang='en-GB'>Error on Process Answer</lang></speak>",
"voiceName": "Emma"
}
];
res.json(ncco);
}
});
