SSE
===

Simple asyncio/aiohttp包装器，用于Server-Sent Events。

使用方法
-----

发送事件

```python
import asyncio
import sse


class Handler(sse.Handler)
@asyncio.coroutine
def handle_request(self)
yield from asyncio.sleep(2)
self.send('foo')
yield from asyncio.sleep(2)
self.send('bar', event='wakeup')

start_server = sse.serve(Handler, 'localhost', 8888)
asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
```

验证传入请求

```python
class Handler(sse.Handler)
def validate_sse(self)
super().validate_sse()
# use self.request / self.payload
if not self.request.path.startswith('/live')
raise sse.SseException()
```

发送JSON数据

```python
class Handler(sse.Handler)
@asyncio.coroutine
def handle_request(self)
self.send({'foo': 'bar'})
```

发送ID / 事件名称 / 重试信息

```python
class Handler(sse.Handler)
@asyncio.coroutine
def handle_request(self)
self.send('some data', id=12345, event='something', retry=10000)
```
