Router middleware for xweb

基本用法

from xweb import App
from xweb_router import Router
app = App()
router = Router()
app.use(router)
@router.get(’/’)
async def home(ctx):
ctx.body = “Home”
if name == ‘main’:
app.listen(8000)

路由插件

from xweb import App
from xweb_router import Router
app = App()
router = Router()
app.use(router)
@router.use(’/’)
async def middleware(ctx, fn):
“”“Router Middleware”""
print(‘middleware’)
await fn()
@router.get(’/’)
async def home(ctx):
ctx.body = “Home”
if name == ‘main’:
app.listen(8000)

动态参数

from xweb import App
from xweb_router import Router
app = App()
router = Router()
@router.get(’/{name}’)
async def hello(ctx):
“”“URL parameters”""
ctx.body = f"Hello {ctx.params.name}"
if name == ‘main’:
app.listen(8000)

嵌套路由


from xweb import App
from xweb_router import Router
app = App()
router = Router()
nested = Router()
app.use(router)
router.use(’/post’)(nested)
@nested.get(’/index’)
async def index(ctx):
ctx.body = “Nested Index”
if name == ‘main’:
app.listen(8000)

Python中如何使用Xweb-Router路由插件

vueper 1楼

Xweb-Router是个轻量级的路由库，用起来挺简单的。先安装：pip install xweb-router。

基本用法就是定义路由函数，然后启动服务：

from xweb_router import Router, run

app = Router()

@app.route('/')
def home():
    return 'Hello, Xweb-Router!'

@app.route('/user/<name>')
def user(name):
    return f'Hello, {name}!'

if __name__ == '__main__':
    run(app, port=8000)

这里<name>是动态参数，访问/user/john就会显示"Hello, john!"。

支持GET、POST这些方法：

@app.route('/api/data', methods=['POST'])
def post_data():
    # 处理POST请求
    return 'Data received'

路由分组可以用Router嵌套：

api = Router()
@api.route('/users')
def get_users():
    return 'User list'

app.add_router('/api', api)

这样/api/users就映射到get_users函数了。

中间件也支持，比如加个简单的日志：

@app.middleware
async def log_middleware(request, next_handler):
    print(f'Request: {request.path}')
    return await next_handler(request)

总结：Xweb-Router用起来挺直观的，适合快速搭建Web服务。
