提交订单接口
<h4><strong>简要描述：</strong></h4>
<p>提交订单接口</p>
<ol>
<li><code>POST请求，Content-Type必须设置为：application/json；</code></li>
<li><code>接口是异步，接口调用成功(即下单成功)，不代表充值成功</code></li>
<li><code>最终“充值结果”，需要调用“订单详情接口”进行查询，由于取卡是异步操作，建议间隔1-3s循环调用，直至最终结果；</code></li>
<li><code>此接口不会返回卡密数据，需要再调用“订单详情接口”获取卡密信息；</code></li>
<li><code>“订单详情接口”必须接入；</code></li>
<li><code>下单接口如果请求超时，请调用订单详情接口确认下单结果；</code></li>
</ol>
<h4><strong>请求URL：</strong></h4>
<p><code>http://平台域名/api/v1/order/buy</code></p>
<h4><strong>请求方式：</strong></h4>
