英文:
Docker python app can't find `PATH_INFO` env variable
问题
I'm trying to run python backend using Docker, however app can't find PATH_INFO environment variable. Though on another machine it works well, difference is OS version: previous is ubuntu 21.04 and current is ubuntu 22.04
The error is caused by this piece of code:
path = environ.get("PATH_INFO", "/").lower()
here environ is a dict containing all env variables
App is running using docker-compose which creates contianer, where ENTRYPOINT includes docker_entry file:
import bjoern
from index import app
bjoern.run(app, '0.0.0.0', 80)
where app is
if __name__ == "__main__":
wsgiref.handlers.CGIHandler().run(app)

PATH_INFO 必须在脚本执行期间设置，它不是操作系统上默认可用的变量。你可以尝试在启动脚本之前或脚本内部打印出所有环境变量。
# bash
env
# python
import os
print(os.environ)
编辑：你可能会假设 Nginx 会为你的脚本设置 PATH_INFO，就像它为 PHP FPM 一样。但实际上并不会。
英文:
PATH_INFO must be set during your script execution, it is not a default variable available on the OS. You likely can try printing out all the env variables before starting your script or inside it.
# bash
env
# python
import os
print(os.environ)
edit: you might be assuming nginx sets PATH_INFO for your script, like it does for PHP FPM. It is not.
