简单的Bottle应用与uWSGI不工作（返回404）

Question

我有一个用Bottle框架做的简单的Hello World应用：

from bottle import route, run
import bottle

app = bottle.Bottle()

@route('/hello')
def hello():
        return "hello world"

if __name__ == '__main__':
    run(port=8080, debug=True)
else:
        application = app

当我用 python bottle-hello.py 运行时，它可以在127.0.0.1:8080上正常工作。但是当我尝试用uWSGI来运行它时：

uwsgi --http :8000 --wsgi-file bottle-hello.py

访问127.0.0.1:8000时出现404未找到的错误。

这是uWSGI输出的日志信息。最后一行显示它收到了请求，但没有返回任何内容...

Answer 1

这是修正后的代码：

import bottle

app = application = bottle.Bottle()

@app.route('/hello')
def hello():
    return "hello world"

if __name__ == '__main__':
    app.run(port=8080, debug=True)
