为什么我的python文件返回无法在uwsgi烧瓶中加载应用程序？

Question

我已经阅读了以下与uwsgi相关的问题，有趣的是，到目前为止没有任何帮助：

• Flask 和 uWSGI - 无法加载应用程序 0 (mountpoint='')（找不到可调用或导入错误）
• uwsgi-nginx-flask: 无法加载应用程序 0 (mountpoint='') (callable not found or import error)
• 无法加载应用程序 0 (mountpoint='') - 带有 uwsgi 的 Flask 应用程序

似乎我需要将 app 作为application导入，因为uWSGI试图找到应用程序变量。

from tf_api import create_app as application

if __name__ == "__main__":
    application = application()
    application.run()
else:
    print("---------------------->", __name__)
    application = application()

当我运行以下命令时：

uwsgi --socket 0.0.0.0:80 --protocol=tcp -w wsgi:app

它转到else部分并输出：

----------------------> wsgi
2020-02-20 14:25:22,168 [tf_core] Initialized! [testing=False]
2020-02-20 14:25:22,176 [tf_api] {"msg": "Initialized! Testing: False", "logger_name": "tf_api", "log_level": "DEBUG", "timestamp": "2020-02-20T14:25:22.176664"}
unable to load app 0 (mountpoint='') (callable not found or import error)
*** no app loaded. going in full dynamic mode ***
uWSGI running as root, you can use --uid/--gid/--chroot options
*** WARNING: you are running uWSGI as root !!! (use the --uid flag) ***
*** uWSGI is running in multiple interpreter mode ***
spawned uWSGI worker 1 (and the only) (pid: 27143, cores: 1)

一些日志是从应用程序打印出来的，然后它打印no app loaded ！

当我将application.run(host='0.0.0.0')放在 else 中时，似乎应用程序开始运行，但在烧瓶默认端口5000而不是在uWSGI ：

----------------------> wsgi

unable to load configuration from /usr/local/lib/python3.6/dist-packages/tf_api/uwsgi

但是它给出了一个与unable to load configuration from . created_app返回app 。 你们认为在uswgi找不到该app的原因是什么？

Answer 1

在uwsgi命令中我使用-w wsgi:app我不得不重命名以下代码：

application = application()

到：

app = application()

没有app.run() ，因为uWSGI本身运行烧瓶应用程序，它是不需要的。
