Sanic学习之helloworld

#text文本输出
from sanic import Sanic
from sanic.response import text

app = Sanic(name="App")


@app.route("/hello")
async def hello(request):
    return text("hello,world")


if __name__ == '__main__':
    app.run(port=8000)  #可自定义地址：host='127.0.0.0'

#访问localhost:8000/hello

def 方法名不能为 test()
app = Sanic(name='app')  #name需要填写
不然会报错：sanic.exceptions.SanicException: Sanic instance cannot be unnamed. Please use Sanic(name='your_application_name') instead.
还有就是
@app.route("/hello") 可以
@app.get("/hello") 也行
