Question

我正在使用Twilio从浏览器拨打电话。当我点击通话时，我收到此错误Uncaught twilio.exception wrong number of segments

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> 
<script type="text/javascript">

    Twilio.Device.setup('@token');

    Twilio.Device.ready(function (device) {
        $("#log").text("Client '@clientName' is ready");
    });

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

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

    Twilio.Device.disconnect(function (conn) {
        $("#log").text("Call ended");
    });

    Twilio.Device.incoming(function (conn) {
        $("#log").text("Incoming connection from " + conn.parameters.From);
        // accept the incoming connection and start two-way audio
        conn.accept();
    });

    function call() {
        // get the phone number or client to connect the call to
        params = { "PhoneNumber": $("#number").val() };
        Twilio.Device.connect(params);
    }

    function hangup() {
        Twilio.Device.disconnectAll();
    }
</script>

<div class="hero-unit" style="background-color: white; margin-left: 650px;">
    <div class="container">
        <h3>Call us and watch us answer!</h3>
        <p style="margin-left: -65px;">Use Twilio to call our office and watch us answer on camera!</p>
        <button class="call" onclick="call();">
            Call
        </button>
        <button class="hangup" onclick="hangup();">
            Hangup
        </button>
        <input type="text" id="number" name="number"
            placeholder="Enter a phone number or client to call" />
    </div>
</div>

在我背后的代码中：

public string TwilioToken
    {
        get
        {
            string accountSid = "*************";
            string authToken = "*************";
            string applicationSid = "************";
            string clientName = "*****";
            if (Request["client"] != null)
            {
                clientName = Request["client"];
            }
            var capability = new TwilioCapability(accountSid, authToken);
            capability.AllowClientOutgoing(applicationSid);
            capability.AllowClientIncoming(clientName);
            return capability.GenerateToken();
        }
    }

Answer 1

Twilio传道者在这里。

我无法告诉您如何获取要在HTML中呈现的TwilioToken属性的值。在这一行的JavaScript中：

Twilio.Device.setup('@token');

@token应该被代码隐藏中生成的值替换。既然你提到了代码隐藏，那么听起来你可能正在使用WebForms。为了在HTML中呈现TwilioToken属性的值，您需要使用类似这样的语法：

Twilio.Device.setup('<%= TwilioToken %>');

当您在浏览器中加载页面时，您会看到该语法被Twilio用于设置JavaScript库的长编码字符串替换。

希望有所帮助。

示例代码显示如下行：

$capability = new Services_Twilio_Capability($TWILIO_SID, $TWILIO_TOKEN);
$capability->allowClientOutgoing('APabe7650f654fc34655fc81ae71caa3ff');
$TOKEN = $capability->generateToken();

后面跟着这个：

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

我收到了同样的错误，直到我意识到我拼错了$ TOKEN并将空字符串传递给Twilio.Device.setup。修好后，错误就消失了。
