from .auth import _basic_auth_str ImportError: attempted relative import with no known parent package

这个错误通常是由于相对导入的问题导致的。在Python中,相对导入是指从当前模块开始,使用相对路径导入其他模块。在使用相对导入时,必须确保当前模块是在一个包中,并且使用相对导入的模块也在同一个包中。如果没有正确设置包结构,就会出现“ImportError: attempted relative import with no known parent package”的错误。
解决这个问题的方法是,将相对导入改为绝对导入,或者正确设置包结构。如果您想使用相对导入,请确保当前模块和要导入的模块都在同一个包中,并且使用相对路径导入。
如果您想使用绝对导入,请使用完整的包名来导入模块,例如:
```python
from mypackage.auth import _basic_auth_str
```
如果您想了解更多关于Python中的导入问题,请参考Python官方文档。

from . import _auth ImportError: attempted relative import with no known parent package
It seems that you are encountering an error related to relative imports in Python. This error typically occurs when you try to perform a relative import without a known parent package.
To resolve this issue, you can try one of the following solutions:
1. Convert the script to a module: If you are running the script directly, consider converting it into a module by creating a package structure. This means creating an `__init__.py` file in the directory containing the script. Then, you can import the module by specifying the package name before the module name.
2. Use absolute imports: Instead of using relative imports, import the module by specifying its absolute path. For example, if your project structure is as follows:
```
project/
package/
__init__.py
module.py
script.py
```
In your `script.py` file, you can use an absolute import like this:
```python
from package.module import something
```
3. Adjust your PYTHONPATH: If the modules you are trying to import are located in different directories, you can modify the PYTHONPATH environment variable to include those directories. This way, Python will search for modules in the specified directories.
Make sure to choose the solution that best fits your project structure and requirements.
from django.contrib.auth.hashers import make_password
这是 Django 提供的用于密码加密的函数,它接收一个字符串参数并返回一个加密后的密码字符串。该函数使用 PBKDF2 算法进行加密,可以确保密码的安全性。
使用示例:
```
password = 'my_password'
hashed_password = make_password(password)
```
默认情况下,该函数会使用随机生成的盐值对密码进行加密,以增加密码的安全性。可以通过传递 salt 参数来指定自定义的盐值。
需要注意的是,该函数只用于密码加密,不能用于密码比较。在验证密码时,应该使用 Django 提供的 check_password 函数。
