from bottle import run
if __name__ == ‘__main__‘:
def application(environ, start_response):
start_response(‘200 OK‘, [(‘Content-Type‘, ‘text/html‘)])
return [‘<h1>Hello world!</h1>‘]
run(host=‘localhost‘, port=8080, app=application)
from bottle import run
import gevent.monkey
gevent.monkey.patch_all()
if __name__ == ‘__main__‘:
def application(environ, start_response):
start_response(‘200 OK‘, [(‘Content-Type‘, ‘text/html‘)])
return [‘<h1>Hello world!</h1>‘]
run(host=‘localhost‘, port=8080, app=application, server = ‘gevent‘)
通过server关键字指定web服务器为‘gevent’，输出的第一行变成了：
def __call__(self, environ, start_response):
""" Each instance of :class:‘Bottle‘ is a WSGI application. """
return self.wsgi(environ, start_response)
def wsgi(self, environ, start_response):
""" The bottle WSGI-interface. """
try:
out = self._cast(self._handle(environ))
# rfc2616 section 4.3
if response._status_code in (100, 101, 204, 304) or environ[‘REQUEST_METHOD‘] == ‘HEAD‘:
if hasattr(out, ‘close‘): out.close()
out = []
start_response(response._status_line, response.headerlist)
return out
_handle：处理请求，最终调用到application ，简化后的代码如下：
1 def _handle(self, environ): 2 self.trigger_hook(‘before_request‘) 3 route, args = self.router.match(environ) 4 out = route.call(**args) 5 self.trigger_hook(‘after_request‘) 6 return out
A Router is an ordered collection of route->target pairs. It is used to efficiently match WSGI requests against a number of routes and return the first target that satisfies the request.
