flask-----No such file or directory绝对路径与相对路径

No such file or directory: '\\uploads\\03.jpeg'

相对路径:加点,或者直接绝对路径(尽量使用绝对路径,通过python的os模块获取当前文件绝对路径)

os.path.dirname(os.path.abspath(__file__))  返回的是文件的目录

os.path.abspath(__file__)返回的是.py文件的绝对路径,包含文件名,并且返回path规范化的绝对路径

 

 

 

相对路径

../表示源文件所在目录的上一级目录,../../表示源文件所在目录的上上级目录,以此类推。
同级目录直接文件名可以直接引用
./下一级目录

来自stackoverflow

Both /tmp and /static/uploads/.., are absolute paths. And your code is looking in the / folder instead of looking in your project's folder. You should use the absolute path to point at your folder /path/to/your/project/static/uploads/.. or use a path relative to the code being executed such as ./static/uploads.

You can also use the following snippet to generate the absolute path:

from os.path import join, dirname, realpath

UPLOADS_PATH = join(dirname(realpath(__file__)), 'static/uploads/..')
