Question

我使用Apache / PHP Server和Django中的表单来处理我的所有帖子/请求。如何设置它以便不设置字段它不会导致错误？

PHP表单：

<form action="http://www.mydomain.com:8003/login/" method="post">
<input type="text" name="email" id="email"><br>
<input type="text" name="password" id="password"><br>
<input type="checkbox" name="remember"><br>
<input type="submit" value="send" id="send">
</form>

Django的：

 from django.http import HttpResponse, HttpResponseRedirect
 from django.shortcuts import render_to_response
 from django.views.decorators.csrf import csrf_exempt

 @csrf_exempt
 def index(request):
     if request.method == 'POST':
         post = request.POST
         email = post['email']
         pass = post['password']
         remember = post['remember']
         if remember:
             expire_v = 30
         else:
             expire_v = None
         response = HttpResponse(email)
         response.set_cookie('emailaddress', email, max_age=expire_v)
         response.set_cookie('password', pass, max_age=expire_v)
         return response

问题是如果没有检查记住而不是导致错误。

此代码存在严重错误，并且不知道错误：从请求中获取参数时尝试使用默认值

email = request.POST.get('email', False)
password = request.POST.get('pass', False) # pass is a keyword in python
remember = request.POST.get('remember', False)
if email and password:
    response = HttpResponse(email)
    if remember:
        response.set_cookie('emailaddress', email, max_age=30)
        response.set_cookie('password', pass, max_age=30)
    return response
 else:
     # do something to indicate a problem
