如果文件不存在，则烧瓶创建一个文件

Question

I'm trying to create a file in my flask application, but when the file doesn't already exist, the code fails. I've tried the two typical solutions:

f = open('f.txt', 'a+')

as well as

with open('f.txt', 'a+') as f:
    ...

What am I doing wrong?

Answer 1

Use Access Control Lists, instead of opening that directory to everyone.

setfacl -m u:flaskuser:rw /some/dir/

Also, check out the documentation on these, it's worth a look : https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/ch-acls.html
