Jquery 验证 - 从服务器端 Django 检查电子邮件和用户名的可用性

问题描述

我正在尝试从使用 Django 编程的服务器端验证电子邮件和用户名可用性的注册表单.我检查了这个 jQuery Validation Plugin remote check for password with Django 但我收到 403 禁止 - CSRF 验证失败.我尝试在 jquery 脚本中包含 csrf 令牌.但仍然无法正常工作.我在下面显示了用于检查电子邮件可用性的代码.

I'm trying to validate the registration form for email and username availability from server-side programmed with Django. I checked this one jQuery Validation Plugin remote check for password with Django but I'm getting 403 forbidden - CSRF verification failed. I tried including csrf token inside the jquery script. But still not working. I've shown the code below for checking email availability.

views.py:

def email_check(request):
    response_str="false"
    if request.is_ajax():
        e = request.POST.get("email_address")
        try:
            obj = User.objects.get(email=e)
        except DoesNotExist:
            response_str="true"
    return HttpResponse(response_str)

urls.py:

url(r'^signup/email/check/$', 'registration.views.email_check')

有人可以帮我解决这个问题吗?

Could anyone help me on this?

谢谢！

推荐答案

您应该在名为X-CSRFToken"的 cookie 中发送 csrf 令牌，有一种方法可以使用 jQuery 全局启用此行为，如下所示:

You should send the csrf token in a cookie named "X-CSRFToken", there is a way to globally enable this behavior with jQuery like this:
