GET 和 POST
## onion.ajax.get / onion.ajax.post
### 1. 功能
发送基本的 get / post 请求
### 2. 使用场景
与后端进行数据交互时
### 3. 如何使用
#### 3.1 GET 请求
```js
onion.ajax.get(url, function (res) {
if (res.code == onion.networkState.SUCC) {
// 成功操作
} else {
onion.layer.tipMsg(res.msg)
}
})
```
#### 3.2 POST请求
```js
onion.ajax.post(url, submitData, function (res) {
if (res.code == onion.networkState.SUCC) {
// 成功操作
} else {
onion.layer.tipMsg(res.msg)
}
})
```
#### 3.3 onion.networkState
后端会返回的状态码, 公共方法中有对应定义
```js
var networkCode = {
'SUCC': 10000, // 成功
'SYSTEMERR': 10001, // 系统异常
'NOTAUTH': 401, // 没有权限
'ERROR': 500 // 网络错误
}
onion.networkState = networkCode;
```
### 4. api定义
``` javascript
* @desc GET 请求方式
*
* @params [string] url
* @params [object] 数据
* @params [function] 回调
*
* */
