fastweb 1.4.1.1

FastWeb is a Python fast-building web frame refered by Tornado, Celery, Thrift

Fastweb - 高速迭代 · 快速试错
============================

依赖 ``Tornado`` ``Celery`` ``Thrift`` 开发的快速构建web应用的框架。

Web层示例
--------

.. code-block:: ini

;组件配置文件(component.ini)

;thrift rpc 组件配置
[tftrpc:hello_service]
host = localhost
port = 8888
thrift_module = gen-py-tornado.HelloService.HelloService
size = 10

;mysql组件配置
[mysql:test_mysql]
host = localhost
port = 3306
user = username
password = password
db = db_name
timeout = 5
charset=utf8
size=5
awake = 300

;mongo组件配置
[mongo:test_mongo]
host = localhost
port = 27017
timeout = 10

;redis组件配置
[redis:test_redis]
host = localhost
port = 6379
db = 1

;task组件配置
[task:test_task]
name = test_task
broker = amqp://guest:guest@localhost:5672//
backend = redis://localhost/0
task_class = some_tasks.add.Add
queue = test_task_queue
exchange = test_task_exchange
routing_key = test_task_routing_key

.. code-block:: python

"""handler（handler.test）"""

from fastweb import Request
from fastweb.web import Api, Page
from fastweb.web import coroutine, run_on_executor

class Test(Api):

@coroutine
@checkArgument(name=str, sex=int)
def get(self):

# 加载handler级别线程池
self.load_executor(5)
# handler级别线程池示例
r = yield self.test_executor()

# mysql使用示例
ret = yield self.test_mysql.query('select * from table limit 20;')
print self.test_mysql.fetch()

# RPC使用示例
yield self.hello_service.sayHello()

# Redis使用示例
yield self.test_redis.call('set', 'name', 'jackson')

# Http请求示例
request = Request(method='GET', url='http://www.baidu.com')
ret = yield self.http_request(request)

# 任务调用示例
yield self.test_task.call_async(args=(101, 2))
x = yield self.test_task.call(args=(101, 2))

# response
self.end('SUC', log=False, **{'name':0})

# 在handler级别线程池中运行
@run_on_executor
def test_executor(self):
time.sleep(10)
return 1000

"""服务加载组件和启动"""

from fastweb.web import start_web_server
from fastweb.loader import app
from fastweb.pattern import SyncPattern, AsynPattern

if __name__ == '__main__':

options.parse_command_line()
app.load_recorder('app.log', system_level='DEBUG')
app.load_configuration(backend='ini', path='component.ini')
app.load_errcode()
app.load_component(pattern=AsynPattern, backend='ini', path=options.config)
app.load_component(pattern=AsynPattern, backend='ini', path='task.ini')

from handler.test import Test

handlers = [(r'/test', Test)]

start_web_server(6666, handlers, debug=True, xheaders=False)


Task层示例
---------

.. code-block:: ini

;task配置文件(task.ini)

;task组件配置
[task:test_task]
name = test_task
broker = amqp://guest:guest@localhost:5672//
backend = redis://localhost/0
task_class = some_tasks.add.Add
queue = test_task_queue
exchange = test_task_exchange
routing_key = test_task_routing_key

.. code-block:: python

class Add(object):
"""任务"""

def run(self, x, y):
return x+y

if __name__ == '__main__':
app.load_recorder('task.log', system_level='DEBUG')
app.load_component(pattern=AsynPattern, backend='ini', path='task.ini')
start_task_worker()

Service层示例
------------

请参考examples中示例。

安装
----

``python setup install``

``pip install fastweb``

适用场景
-------

Fastweb是一个快速构建web应用的框架，与Python的哲学相同，都是期望能够让使用者更快速的开发出满足需求的后端代码。
高速迭代，快速试错，这是使用Fastweb最大的效益！
