php – Twilio视频调用API实现

我正在为我的项目实现视频调用api,当我通过“生成访问令牌”选项从 https://www.twilio.com/user/account/video/dev-tools/testing-tools创建访问令牌时,它将为我提供新生成的令牌,当我在下面使用它时

var accessToken = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiIsImN0eSI6InR3aWxpby1mcGE7dj0xIn0.eyJqdGkiOiJTSzk3ZDI2NGIyOTU1YjM2OWMyOGU4MjA4M2E5MjlmMmE0LTE0NjYwODE1NzQiLCJpc3MiOiJTSzk3ZDI2NGIyOTU1YjM2OWMyOGU4MjA4M2E5MjlmMmE0Iiwic3ViIjoiQUM5ZWE5YjY3ZmM3ZjBjMzE2NTBjNGRmNzkyYzhjYjI2NiIsImV4cCI6MTQ2NjA4NTE3NCwiZ3JhbnRzIjp7ImlkZW50aXR5IjoiQUM5ZWE5YjY3ZmM3ZjBjMzE2NTBjNGRmNzkyYzhjYjI2NiIsInJ0YyI6eyJjb25maWd1cmF0aW9uX3Byb2ZpbGVfc2lkIjoiVlMwNmYzZDdiNTczNGVlYTJhZDdjMWEzYzY4YmMzNjhjNSJ9fX0.976iQ2bMB_tAORxjGkgZFJ-UYGfTidTwfvV0fzySMP0";

var accessManager = new Twilio.AccessManager(accessToken);

它对我很有用.

现在当我使用第二个选项“通过Helper Library with PHP生成访问令牌”并尝试生成令牌时

// Create an Access Token
$token = new Services_Twilio_AccessToken(
    $accountSid,$apiKeySid,$apiKeySecret,$ttl=3600,$identity=$identity
);

// Grant access to Conversations
$grant = new Services_Twilio_Auth_ConversationsGrant();
$grant->setConfigurationProfileSid($configurationProfileSid);
$token->addGrant($grant);

echo json_encode(array(
    'identity' => $identity,'token' => $token->toJWT(),));

它也会为我生成令牌,但是当我使用生成的令牌时

响应令牌：

{"identity":"GoldenZeldaGunsight","token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiIsImN0eSI6InR3aWxpby1mcGE7dj0xIn0

.vkOxI1tMIWNQVm1AUL1ySTZY5ZyjYDTdvWCKnVIkLmk"}

我在中使用此响应令牌

var accessManager = new Twilio.AccessManager(data.token);

它对我不起作用.它会给我一些错误

“Could not connect to Twilio: undefined…”

此外,我在https://jwt.io测试了两个令牌,它对我来说非常适合.

任何人都可以帮助我在这个问题我错了代码,如果你想,那么我也可以通过其他凭据细节？

提前致谢.

Solved

伙计们,我在Support的帮助下解决了这个问题.

解

在旧版本的/Services/Twilio/AccessToken.php中,我有一个属性“nbf”：1466743969(不是在时间之前),这意味着它在04：52：49 UTC之前无效.但是根据日志文件中的时间戳,它是04:50:27 UTC(10:20:27 IST)`.如果生成访问令牌的服务器的系统时钟快几分钟,则会导致前一段时间无效.

由于时钟偏差问题,twilio-php库的更高版本默认省略了“nbf”属性.如果您在此处获得最新版本的AccessToken.php：

https://github.com/twilio/twilio-php/blob/master/Services/Twilio/AccessToken.php

它会在没有“nbf”的情况下生成访问令牌.

另一种解决方法是确保服务器时间准确,但您需要管理员访问权限才能进行调整.

include '/pathto/Services/Twilio/Capability.php';

// Twilio API credentials here
$accountSid = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$authToken  = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy';

$capability = new Services_Twilio_Capability($accountSid,$authToken);
$capability->allowClientOutgoing('APabe7650f654fc34655fc81ae71caa3ff');
$token = $capability->generateToken();

<script type="text/javascript">

      Twilio.Device.setup("<?php echo $token; ?>");

      Twilio.Device.ready(function (device) {
        $("#log").text("Ready");
      });

      Twilio.Device.error(function (error) {
        $("#log").text("Error: " + error.message);
      });

      Twilio.Device.connect(function (conn) {
        $("#log").text("Successfully established call");
      });

      function call() {
        Twilio.Device.connect();
      }
    </script>

$.getJSON('/token',function(data) {
// The data sent back from the server should contain a long string - this is
// the JWT token you need to initialize the SDK. Read more about JWT 
// (JSON Web Token) at http://jwt.io
console.log(data.token);

//If your app has an existing authentication system,you can use
// the e-mail address or username that uniquely identifies a user instead.
 console.log(data.identity);
});

<?php
  require_once('./twilio-php/Services/Twilio.php');
  require_once('./randos.php');
  require_once('./config.php');

  // choose a random username for the connecting user
   $identity = randomUsername();

  // Create access token,which we will serialize and send to the client
  $token = new Services_Twilio_AccessToken(
     $TWILIO_ACCOUNT_SID,$TWILIO_API_KEY,$TWILIO_API_SECRET,3600,$identity
   );

  // Grant access to Conversations
  $grant = new Services_Twilio_Auth_ConversationsGrant();
  $grant->setConfigurationProfileSid($TWILIO_CONFIGURATION_SID);
  $token->addGrant($grant);

  // return serialized token and the user's randomly generated ID
  echo json_encode(array(
    'identity' => $identity,));

// Create an AccessManager to manage our Access Token
var accessManager = new Twilio.AccessManager('$TWILIO_ACCESS_TOKEN');

// Create a Conversations Client and connect to Twilio's backend
conversationsClient = new Twilio.Conversations.Client(accessManager);
conversationsClient.listen().then(function() {
    console.log('Connected to Twilio!');
},function (error) {
