Python 将 b'xxxx' 写入配置并读取它

Question

我加密了一个密码，结果是这样的：b'&Ti\xcfK\x15\xe2\x19\x0c' 我想将它保存到配置文件并重新加载它所以我可以解密它，我可以再次使用它作为密码

Answer 1

看看 Python 的 open 内置函数。

with open('foo.txt', 'wb') as f:
    f.write(b'&Ti\xcfK\x15\xe2\x19\x0c')

Answer 2

# To save it:
with open('file-to-save-password', 'bw') as f:
    f.write( b'&Ti\xcfK\x15\xe2\x19\x0c')

# To read it:
with open('file-to-save-password', 'br') as f:
    print(f.read())

Answer 3

你可以这样做：

# to write the file

cryptpw = "your encrypted password"

config = open("/path/to/config/file/pw.config","w")
config.write(cryptpw)
config.close()

# to reopen it

config = open("/path/to/config/file/pw.config","r")
print(config.read())
config.close()

这取决于你如何处理那个文件的内容，我只是选择打印它。

Answer 4

python persistence 在这里很有用。例如：

import shelve

with shelve.open('secrets') as db:
    db['password'] = b'&Ti\xcfK\x15\xe2\x19\x0c'

Python 将 b'xxxx' 写入配置并读取它

Python write b'xxxx' to config and read it
