Question

所以我用QtDesigner创建了一个注册窗口，该窗口将用户的信息存储在DataFrame中。但是对于密码，我希望它被散列。现在，当程序到达 HPW Line 时，将引发此错误：

File "c:/Users/pc/Desktop/qt_test_auth/su_win.py", line 225, in confirmFunc
HPW = hashlib.sha512(PW.encode('utf-8') + salt).hexdigest()

TypeError: can't concat str to bytes

我尝试自行调试，但无法。非常感谢你！

问题很简单：salt是docs所指示的字符串：

UUID.hex

UUID为32个字符的十六进制字符串。

因此，如果要连接，必须将其转换为字节，如下所示：

HPW = hashlib.sha512(PW.encode('utf-8') + salt.encode('utf-8')).hexdigest()

Py / Qt5：TypeError：无法将str连接为字节
