你如何用polygit正确导入iron-ajax？这给了我400错误
<base href="https://polygit.org/components/">
<script src="webcomponentsjs/webcomponents-lite.min.js"></script>
<link href="polymer/polymer.html" rel="import">
<link rel="import" href="iron-ajax/iron-ajax.html">

Polygit已弃用，不再有效。您可以在演示中使用以下<base>网址：
<head>
<base href="https://cdn.rawgit.com/download/polymer-cdn/1.8.0/lib/">
<link rel="import" href="polymer/polymer.html">
<script src="webcomponentsjs/webcomponents-lite.js"></script>
<link rel="import" href="iron-ajax/iron-ajax.html">
</head>
<body>
<x-foo></x-foo>
<dom-module id="x-foo">
<template>
<div>Please wait...</div>
<iron-ajax id="ajax"
auto
url="http://jsonplaceholder.typicode.com/users/"
last-response="{{data}}"
handleAs="json">
</iron-ajax>
<table>
<template is="dom-repeat" items="[[data]]">
<tr>
<td>[[item.id]]</td>
<td>[[item.name]]</td>
<td>[[item.email]]</td>
</tr>
</template>
</table>
</template>
<script>
HTMLImports.whenReady(function() {
Polymer({
is: 'x-foo'
});
});
</script>
</dom-module>
</body>
