+#### 使用示例
+- 加密 :
+```javascript
+let signString =config.method == 'post' ? genSign(config.data) : genSign(config.params)
+```
+- 解密:
+```javascript
+let data=JSON.parse(decodeData(response.data.data))
+```
+#### 注意
+```javascript
+// 注意：因为浏览器会把get请求参数里面的空格用 '+'连接起来，这里需要引入qs包进行处理:
+import QS from 'qs'
+axios.defaults.paramsSerializer = function (params) {
+return QS.stringify(params, { arrayFormat: 'brackets' })
+}
