   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no 
similar issues.
   
   
   ### Apache SkyWalking Component
   
   Python Agent (apache/skywalking-python)
   
   ### What happened
   
   It will have a issue when the app start with the Fastapi, as follows:
   
   > INFO:     Finished server process [30539]
   > INFO:     Started server process [30544]
   > INFO:     Waiting for application startup.
   > **INFO:     ASGI 'lifespan' protocol appears unsupported.**
   > INFO:     Application startup complete.
   
   and the startup and shutdown event will have no effect.
   
   ```
       @app.on_event("startup")
       async def init_connect():
           db.connect()
   
       @app.on_event('shutdown')
       async def shutdown_connect():
           if not db.is_closed():
               db.close()
   ```
   
   So, i debug it, i find that the plugin 'sw_fastapi' doesn't consider the 
scenario when the scope type is not the http.This bug is not compatible with 
the uvicorn. When i add the code , it will work.
   
   ```
   def install():
       from starlette.types import Receive, Scope, Send, Message
       from starlette.exceptions import ExceptionMiddleware
   
       _original_fast_api = ExceptionMiddleware.__call__
   
       def params_tostring(params):
           return '\n'.join([f"{k}=[{','.join(params.getlist(k))}]" for k, _ in 
params.items()])
   
       async def _sw_fast_api(self, scope: Scope, receive: Receive, send: Send):
           from starlette.requests import Request
   
           **if scope["type"] != "http":
               await _original_fast_api(self, scope, receive, send)
               return**
   
           req = Request(scope, receive=receive, send=send)
           carrier = Carrier()
           method = req.method
   ```
   
   
   
   ### What you expected to happen
   
   When i define the startup and shudown event ,they will do
   
   ### How to reproduce
   
   The scenario is as follows:
   Fastapi 0.85.1
   apache-skywalking 0.8.0
   
   when you use the Fastapi startup and shudown event,it will occur
