+## API
+
+### origin 
+> 返回原始的response & request对象
+
+```js
+console.log(request.origin) // {req: request, res: response}
+```
+
+
+### app
+> 返回一级路由的名字
+
+```js
+// abc.com/foo/bar
+console.log(request.app) // foo
+```
+
+
+### path
+> 以数组形式,返回除一级路由之外剩下的路径
+
+```js
+// abc.com/foo/bar/aa/bb
+console.log(request.path) // ['bar', 'aa', 'bb']
+```
+
+### url
+> 返回修正过的url路径
+
+```js
+// abc.com/foo/bar/aa/bb
+// abc.com////foo///bar/aa/bb
+console.log(request.url) // foo/bar/aa/bb
+```
+
+
+
+### get([key[,xss]])
+
+* key `<String>` 字段名 [可选], 不则返回全部参数
+* xss `<Boolean>` 是否进行xss过滤 [可选], 默认为ture
+
+> 返回URL上的query参数, 类似于`$_GET[]`;
+
+
+```javascript
+// http://test.com?name=foo&age=18
+request.get('name') // foo
+request.get('age') // 18
+
+request.get() // {name: 'foo', age: 18}
+request.get('weight') // return null if not exists
+```
+
+### post([key[,xss]])
+
+* key `<String>` optional
+* xss `<Boolean>` optional
+
+> 读取post请求的body, 类似于 `$_POST[]`.
+
+> **该方法返回的是Promise对象**
+
+```javascript
+// http://test.com
+await request.post('name') // foo
+await request.post('age') // 18
+
+// return all if not yet argument given
+await request.post() // {name: 'foo', age: 18}
+await request.post('weight') // return null if not exists
+```
+
+### header([key])
+
+* key `<String>` 字段名[可选], 不传则返回全部
+
+> 返回请求头
+
+```javascript
+request.header('user-agent') // Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 ...
+
+// return all if not yet argument given
+request.header() // {'user-agent': '...'[, ...]}
+```
+
+### ip()
+
+> 获取客户端IP地址.
+>
+> It would return '127.0.0.1' maybe if in local area network.
+
+
+### cookie(key)
+
+> 获取客户端带上的cookie.
+> 不传key时返回所有的
