/**
* 阿里大鱼(www.alidayu.com)短信发送类
* 适用ThinkPHP版本3.2
* 请将本类放在ThinkPHP\Library\Org\Util目录下
* 使用方法1：
---------------------code begin---------------------
$alisms = new \Org\Util\AliSms("appkey","secretkey");
$result = $alisms->sign('短信签名')->data(短信模板变量[数组])->code('短信模板ID')->send('短信接收号码');
---------------------code   end---------------------

* 使用方法2：
首先在配置文件中增加配置项：
'ALI_SMS_APP_KEY'=>'appkey',
'ALI_SMS_SECRET_KEY'=>'secretkey',

然后如下使用：
---------------------code begin---------------------
$alisms = new \Org\Util\AliSms('短信模板ID',短信模板变量[数组],'短信签名');
$result = $alisms->send('短信接收号码');
---------------------code   end---------------------
或：
---------------------code begin---------------------
$result = (new \Org\Util\AliSms('短信模板ID',短信模板变量[数组],'短信签名'))->send('短信接收号码');
---------------------code   end---------------------
或：
---------------------code begin---------------------
new \Org\Util\AliSms('短信模板ID',短信模板变量[数组],'短信签名','短信接收号码',$result);
---------------------code   end---------------------
以上最后例子中$result传递的是变量地址

返回值：
参考 http://open.taobao.com/doc2/apiDetail.htm?spm=a219a.7629065.0.0.h5jQfz&apiId=25450&docType= 的返回示例
但本类去除了第一层无意义数据，并加上status和info两个返回值；status为0表示发送失败，status为1表示发送成功；info在一定程度上可以作为发送结果文本

参数说明：
1.短信签名必须是在阿里大鱼“管理中心-短信签名管理”中的可用签名。如“阿里大鱼”已在短信签名管理中通过审核，则可传入”阿里大鱼“（传参时去掉引号）作为短信签名。短信效果示例：【阿里大鱼】欢迎使用阿里大鱼服务。
2.短信模板变量，传参规则{"key":"value"}，key的名字须和申请模板中的变量名一致，多个变量之间以逗号隔开。示例：针对模板“验证码${code}，您正在进行${product}身份验证，打死不要告诉别人哦！”，传参时需传入{"code":"1234","product":"alidayu"}
  注：官方API使用JSON作为参数，本累中直接使用数组即可，如：["code"=>"1234","product"=>"alidayu"]
3.短信接收号码。支持单个或多个手机号码，传入号码为11位手机号码，不能加0或+86。群发短信需传入多个号码，以英文逗号分隔，一次调用最多传入200个号码。示例：18600000000,13911111111,13322222222
4.短信模板ID，传入的模板必须是在阿里大鱼“管理中心-短信模板管理”中的可用模板。示例：SMS_585014
