使用pecan可以方便的构建restful api
配置文件test.ini
[composite:hello]
use = egg:Paste#urlmap
/ = hello
[pipeline:hello]
pipeline = main
[app:main]
paste.app_factory = main:app_factory
root = main.Controller
main.py简单文件
import wsgiref.simple_server as wss
from paste import deploy
from pecan import expose, Response
import pecan
class Controller(object):
@expose()
def hello(self):
return Response('Hello, World!', 202)
def build_wsgi_app():
import os
abspath = os.path.dirname(os.path.abspath(__file__))
conf_path = os.path.join(abspath, "hello.ini")
app = deploy.loadapp("config:{0}".format(conf_path), name="main")
return app
def app_factory(global_config, **local_conf):
return pecan.make_app(root=local_conf.get('root'))
if __name__ == "__main__":
server = wss.make_server('', 8000, build_wsgi_app())
server.serve_forever()
配置文件中，构建一个叫hello的composite，使用一个叫hello的pipeline。pipeline使用Controller作为控制器。
build_wsgi_app 加载配置文件。
运行server
python main.py
