如何以编程方式将可调用对象传递给 gunicorn 而不是参数

Question

我有以下实现来使用 gunicorn 启动网络应用程序

@click.command("run_app", help="starts application in gunicorn")
def run_uwsgi():
    """
    Runs the project in gunicorn
    """

    import sys

    sys.argv = ["--gunicorn"]

    sys.argv.append("-b 0.0.0.0:5000")
    sys.argv.append("myapp.wsgi:application")

    WSGIApplication(usage="%(prog)s [OPTIONS] [APP_MODULE]").run()

这将根据要求使用 gunicorn 启动应用程序如何在不使用参数的情况下启动它？有没有办法为 gunicorn 分配 sys.argv 值？

Answer 1

我想要post我已经制定的解决方案

@click.command("uwsgi", help="starts application in gunicorn")
def run_uwsgi():
    """
    Runs the project in gunicorn
    """
    from gunicorn.app.base import Application

    import sys

    class MyApplication(Application):
        """
        Bypasses the class `WSGIApplication` and made it 
        independent from command line arguments
        """
        def init(self, parser, opts, args):

            self.cfg.set("default_proc_name", args[0])

            # Added this to ensure the application integrity
            self.app_uri = "myapp.wsgi:application"

        def load_wsgiapp(self):
            # This would do the trick
            # returns application callable
            return application

        def load(self):
            return self.load_wsgiapp()

    sys.argv = ["--gunicorn"]

    sys.argv.append(f"-b {os.environ['APP_HOST']}:{os.environ['APP_PORT']}")

    # Throws an error if this is missing.
    sys.argv.append("myapp.wsgi:application")

    MyApplication(usage="%(prog)s [OPTIONS] [APP_MODULE]").run()

我直接从

返回了可调用对象

def load_wsgiapp(self):
    # This would do the trick
    # returns application callable
    return application

wsgi.py

application = main.create_app()

但仍然需要为模块传递命令行参数，否则会引发错误。如果您使用 Nuitka 来捆绑您的应用程序，您可以将其启动并与 gunicorn 一起使用。
