=== 主机注册相关的API ===

==== 终端设备Ping ====

    POST http://192.168.11.87:3000/v2/service/ping.json?sn=233232232323&request_time=23232323

需要的请求参数:
* sn : 终端设备的序列号
* request_time : 终端设备的机器时间

===== 错误区理 =====

当sn参数不对时(不存在或者位数不对)，返回的http状态码是406, 返回的结果如下:

<pre>
{"error_message":"Error sn param."}
</pre>

当request_time参数不对时，返回的http状态码是406, 返回的结果如下:
<pre>
{"error_message":"Error request_time param."}
</pre>

当主机信息不正确时(如主机uuid不存在), 返回的http状态码是500, 返回的结果如下:
<pre>
{"error_message":"Server infomation lost."}
</pre>

当主机接口信息不正确时(至少要返回一个主机接口), 返回的http状态码是500, 返回的结果如下:
<pre>
{"error_message":"Server intefaces lost."}
</pre>

===== 正常的响应 =====

响应结果是:
<pre>

* meta: 分别表示客户端发起请求的时间，服务器开始处理的时间，服务器生成响应的时间
* server: 表示主机相关的信息
* interfaces: 表示主机接口列表


=== API调用说明 ===

目前服务器端开放的API包括终端 、频道、媒体文件等方面。
在调用API时，需要在访问接口中加上所调用的终端的access_token:

    http://api_url_bala_bala.json?access_token=your_terminal_access_token

* 如果URL中的access_token不正确，主机会返回http状态码为`403`, 响应正文是

<pre>
{"message":"Error token"}
</pre>

* 如果终端是未注册状态，主机会返回http状态码为`403`, 响应正文是

<pre>
{"message":"Device not registered"}
</pre>
