Service implement api or sdk of 3rd party.
实现第三方平台接口的公用服务,通过API调用。
## 已对接功能
* 阿里云的短信发送接口
## 接口参数签名方法
将所有参数按字母排序之后转换成JSON字符串(注意需保持斜杠/和unicode字符串不转义),最后再拼接上token计算MD5值。
示例如下:
```
var token = 'hello world'; //config.js里配置的密钥
var params = { //参数示例
"b": 2,
"a": 1,
"t": 234343
};
var sortObj = function(obj) { //参数排序方法
return Object.keys(obj).sort().reduce(function(result, key) {
result[key] = obj[key];
return result;
}, {});
};
//1. 排序参数
var sortedParams = sortObj(params);
//2. 计算MD5值
var sign = md5( JSON.stringify(sortedParams) + token );
```
