POST 方法不从输入字段传递值密码

Question

这里的表单是通过 POST 方法提交的，但是在 type=password 的输入字段中给出的密码没有分配给用户注册 function.When 中给出的 'upassword' 我打印 'upassword' 它给出了一个输出“None”。当我给出 JAVASCRIPT 验证时它也给出了这样的错误。

Internal Server Error: /Salon/Registration/

Answer 1

您提交的是 pass 和 cpass，而不是 password 和 cpassword，因此请将其更改为：

    spassword = request.POST.get('pass')
    scpassword = request.POST.get('cpass')

Answer 2

您访问 password 和 cpassword 而您为这些字段设置的 name 实际上是 pass 和 cpass:

<input type="password" class="form-control" id="password" name="pass" placeholder="Password">

<input type="password" class="form-control" id="cpassword" name="cpass" placeholder="Confirm Password">

如果您更改代码以使用正确的字段名称，它将起作用：

   spassword = request.POST.get('pass')
   scpassword = request.POST.get('cpass')

您可能已经通过查看 POST 请求中发送的实际数据发现了这一点，因此我对未来的建议是始终首先在浏览器的开发工具中检查您的请求。
