python - 运行python脚本时出现gunicorn错误

问题描述

这是我的python代码。

    from aiohttp import web

    if __name__ == "__main__":
        app = web.Application()
        cors = aiohttp_cors.setup(app)

        app.on_shutdown.append(on_shutdown)
        app.router.add_get("/", index)
        app.router.add_get("/client.js", javascript)

        cors = aiohttp_cors.setup(app, defaults={
            "*": aiohttp_cors.ResourceOptions(
                    allow_credentials=True,
                    expose_headers="*",
                    allow_headers="*",
                )
        })
        resource = cors.add(app.router.add_resource("/offer"))
        cors.add(resource.add_route("POST", offer))

        resource = cors.add(app.router.add_resource("/image_makeup"))
        cors.add(resource.add_route("POST", image_makeup))
        
        web.run_app(
            app, access_log=None, host=args.host, port=args.port, ssl_context=ssl_context
        )

命令：

gunicorn main:app --bind localhost:8080 --worker-class aiohttp.GunicornWebWorker

错误：

我的根目录中有 main.py 仍然出现上述错误。请看看我在哪里犯了错误。

解决方案

由于您没有直接运行文件“main.py”，因此变量的值__name__不是__main__but main。你需要改变你的if陈述：

if __name__ == "main":
    app = web.Application()
    ...
