与gaiohttp Worker 的gunicorn总是返回404与烧瓶应用程序

提问于

我正在使用nginx代理后面的gunicorn运行一个烧瓶应用程序,并试图让gaiohttp工作者工作 . 当选择gaiohttp worker时,应用程序只返回所有URL的404

使用sync或gevent worker时一切正常 . 也没有直接运行gunicorn和gaiohttp即不使用nginx它工作正常 .

我已经阅读了我能找到的一切 .

我错过了什么吗?在nginx代理后运行时,gaiohttp worker是否有效?

我的nginx配置:

location /app {
    proxy_pass http://127.0.0.1:9002;
    rewrite    /app(.*) /$1  break;
    proxy_redirect     off;
    proxy_buffering on;
    proxy_pass_header Server;
    proxy_set_header X-Scheme $scheme;
    proxy_set_header   Host             $host;
    proxy_set_header   X-Real-IP        $remote_addr;
    proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Host $server_name;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Script-Name /app;
    }

gunicorn:

/usr/bin/gunicorn --workers 2 -k gaiohttp -b 127.0.0.1:9002 app:app

使用最新版本的gunicorn等

    我设法解决了这个问题 .

    这里的行导致了nginx配置中的问题:

    rewrite /app(.*) /$1 break;

    我需要在我的Flask应用程序中使用代理中间件来正确处理反向代理 .

    class ReverseProxied(object):
    '''Wrap the application in this middleware and configure the
    front-end server to add these headers, to let you quietly bind
    this to a URL other than / and to an HTTP scheme that is
    different than what is used locally.
    
    In nginx:
    location /myprefix {
        proxy_pass http://192.168.0.1:5001;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
        proxy_set_header X-Script-Name /myprefix;
        }
    
    :param app: the WSGI application
    '''
    def __init__(self, app):
        self.app = app
    
    def __call__(self, environ, start_response):
        script_name = environ.get('HTTP_X_SCRIPT_NAME', '')
        if script_name:
            server = environ.get('HTTP_X_FORWARDED_SERVER', '')
            if server:
                environ['HTTP_HOST'] = server
            environ['SCRIPT_NAME'] = script_name
            path_info = environ['PATH_INFO']
            if path_info.startswith(script_name):
                environ['PATH_INFO'] = path_info[len(script_name):]
    
        scheme = environ.get('HTTP_X_SCHEME', '')
        if scheme:
            environ['wsgi.url_scheme'] = scheme
        return self.app(environ, start_response)
    

    在应用程序的 __init__.py 中: app.wsgi_app = ReverseProxied(app.wsgi_app)
