我正在用 JavaScript 创建一个 Pebble 应用程序，用于显示我所在城市的公交时间。我目前在向相关 API 发送 AJAX 请求时遇到了困难。我的代码如下：

var UI = require('ui'); 
var ajax = require('ajax');
var card = new UI.Card({ 
    title:'Bus data', 
    subtitle:'Fetching...' }); 
ajax({ 
    url: "http://siri.nxtbus.act.gov.au:11000/APIKEY/pt/service.xml", 
    method: "post", 
    type: 'xml', 
    data: '<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?><Siri version="2.0" xmlns:ns2="http://www.ifopt.org.uk/acsb" xmlns="http://www.siri.org.uk/siri" xmlns:ns4="http://datex2.eu/schema/2_0RC1/2_0" xmlns:ns3="http://www.ifopt.org.uk/ifopt"><ServiceRequest><RequestTimestamp>2013-12-29T12:58:29</RequestTimestamp><RequestorRef>APIKEY</RequestorRef><ProductionTimetableRequest version="2.0"><RequestTimestamp>2013-12-29T12:58:29</RequestTimestamp><ValidityPeriod><StartTime>2015-02-20T13:50:04+01:00</StartTime><EndTime>2015-02-21T13:50:04+01:00</EndTime></ValidityPeriod><Lines><LineDirection><LineRef>ACT_200</LineRef><DirectionRef>A</DirectionRef></LineDirection></Lines></ProductionTimetableRequest></ServiceRequest></Siri>' 
},  function(data) { 
        // Success! 
        console.log('Successfully fetched bus data!'); 
        console.log(data); }, 
    function(error) { 
        // Failure! 
        console.log('Failed fetching weather data: ' + error); 
    } 
);

但是，这是我得到的 AJAX 响应：

<Siri xmlns="http://www.siri.org.uk/siri" xmlns:ns2="http://www.ifopt.org.uk/acsb" xmlns:ns3="http://www.ifopt.org.uk/ifopt" xmlns:ns4="http://datex2.eu/schema/2_0RC1/2_0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://www.siri.org.uk/siri ../siri.xsd">
<ServiceDelivery>
    <ResponseTimestamp>2015-02-20T16:44:41+11:00</ResponseTimestamp>
    <ProducerRef>ACT</ProducerRef>
    <Status>false</Status>
    <ErrorCondition>
        <OtherError number="103">
            <ErrorText>wrong subscription request XML structure</ErrorText>
        </OtherError>
    </ErrorCondition>
</ServiceDelivery>
</Siri>

我不确定为什么会收到此回复，我非常感谢您在这件事上提供的帮助。
