带有 uWSGI 的简单 Bottle 应用程序不工作（返回 404）答案

【问题标题】：simple Bottle app with uWSGI not working (returns 404)带有 uWSGI 的简单 Bottle 应用程序不工作（返回 404）

【问题描述】：

我有一个用 Bottle 构建的简单的 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

当由python bottle-hello.py 运行时，它可以在 127.0.0.1:8080 上运行。但是当我尝试使用 uWSGI 运行它时：

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

访问 127.0.0.1:8000 会出现 404 not found 错误。

这是来自 uWSGI 输出的日志信息。最后一行显示它接收到请求但没有返回任何内容...

【问题讨论】：

您的路线设置为/hello。 127.0.0.1:8000/hello 有效吗？
@Jan 下面的解决方案有效。显然，当被uWSGI调用时，所有函数都需要有app。前缀。

【解决方案1】：

这里是更正的代码：

import bottle

app = application = bottle.Bottle()

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

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