Fastweb - 高速迭代 · 快速试错
============================
|build-status|
依赖 ``Tornado`` ``Celery`` ``Thrift`` 开发的快速构建web应用的框架。
Web层示例

;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

;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

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//

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！
抉择
