本文详细介绍了在Django框架中实现用户忘记密码后的重置流程及通过SMTP发送重置密码邮件的具体代码实现。

urls.py代码如下:

from .views import forget_pass
urlpatterns = [
    # 忘记密码
    path('forget_pass', forget_pass, name='forget_pass'),
]

views.py代码如下:

def forget_pass(request):
    if request.method == "POST":
        user = request.POST['user']
        get_email = request.POST['email']
        username = User.objects.filter(username=user)

        # 输入的账号不存在时,报错
        if not username:
            return render(request, 'forget_pass.html', {'user_error': '您输入的账号不存在.'})

        # 输入账号存在时,做如下检查
        else:

            # 检查输入的邮箱与现存的邮箱是否匹配.username因为是QuerySet类型,所以要加[0].
            if get_email != username[0].email:
                return render(request, 'forget_pass.html', {'email_error': '您输入的邮箱不对,请检查.'})

            # 如果输入的账号与邮箱匹配,则重置密码,并发送邮件.
            else:
                import random
                from .utils import Email

                # 产生随机8位密码
                random_password = ""
                for x in range(8):
                    random_num = str(random.randint(0, 9))
                    random_low_alpha = chr(random.randint(97, 122))
                    random_upper_alpha = chr(random.randint(65, 90))
                    random_char = random.choice([random_num, random_low_alpha, random_upper_alpha])
                    random_password += random_char

                # 重置密码
                username[0].set_password(random_password)
                username[0].save()

                # 发送重置密码邮件
                content_plain = "您好,您收到这封邮件,是因为你选择了忘记密码,重置了密码,新的密码为: %s" % random_password
                email = Email(
                    smtp_server='smtp.163.com',
                    from_addr='XXXXX@163.com',
                    password='XXXXXXX',
                    to_addr=get_email,
                    type='plain',
                    title='重置密码',
                    content=content_plain
                )
                flag = email.send_msg()
                # 邮件发送成功标记
                if flag == 1:
                    return render(request, 'forget_pass.html', {'success': "重置密码已发邮件"})

                # 邮件发送失败反馈
                else:
                    return render(request, 'forget_pass.html', {'send_email_failed': flag})

    # 如果request是GET,则返回如下
    else:
        return render(request, 'forget_pass.html')

utls.py用于发送邮件的代码:

class Email(object):
    """
    # smtp服务器以及相关配置信息
    smtp_server = 'smtp.163.com'
    from_addr = 'XXXX@163.com'
    password = 'XXXXXX'   # 网易授权码,非邮箱登入密码.
    to_addr = 'XXXX@XXXX.cn'    # 接收邮箱
    type = 'html'               发送html格式(html格式发送邮件,比较容易被当做垃圾邮件处理)的邮件内容,还可以选择为"plain",纯文本格式
    title = '使用smtp库发送'     # 邮件标题
    content = '''               # html格式的邮件内容
        <html>
            <body>
                <h1>附件是相关的IPv6材料</h1>
