请任何人解决这个问题。 感谢

3 个答案:

答案 0 :(得分:4)

看起来你正试图用它来实现自己的注册框架。现有的有什么问题?我认为你应该阅读更多关于Django框架的内容并仔细阅读教程。

查看该追溯,问题出在hashlib.new(str(random.random())).hexdigest()[:5]行。 (熟悉查看回溯并找出问题所在,当你犯错误时,你会发现你经常需要这样做。)

help(hashlib.new)显示了这一点:

__hash_new(name, string='')
    new(name, string='') - Return a new hashing object using the named algorithm;
    optionally initialized with a string.

“命名算法”应为md5,sha1,sha256等(有关列表,请参阅help(hashlib),以及如何使用hashlib.md5()代替hashlib.new('md5')。)

答案 1 :(得分:1)

haslib.new()期望散列算法名称(例如“md5”,“sha1”等)作为第一个参数。你传递的是随机字符串。

答案 2 :(得分:0)

当密码在当时保存而不是 hashlib 时,我使用 sha 加密alog,工作正常
