本文主要向大家分享了Python编程中通过Django模块实现用户注册以及邮箱验证功能的简单介绍及代码实现，具体如下。

用户注册:

类似于用户登陆，同样在users.views.py中添加RegisterView(View)类，其中对表单的get和post作出处理。
如果是get方法，重新返回register页面让用户进行填写。

def get(self, request): register_form = RegisterForm() return render(request, "register.html", {'register_form':register_form})

method = POST时，用户注册逻辑：

def post(self, request): # 实例化form，验证每个字段是否合法 register_form = RegisterForm(request.POST) pre_check = register_form.is_valid() if pre_check: # 取出email和password user_name = request.POST.get("email", "") pass_word = request.POST.get("password", "") # 实例化用户，然后赋值 user_profile = UserProfile() user_profile.username = user_name user_profile.email = user_name # 新建用户为非活跃用户，可通过验证变为活跃用户 user_profile.is_active = False # 将明文转换为密文赋给password user_profile.password = make_password(pass_word) user_profile.save() # 保存到数据库 # 此处加入了邮箱验证的手段 send_register_email(user_name, "register") return render(request, "login.html") else: # form表单验证失败，将错误信息传给前端 return render(request, "register.html", {"register_form": register_form})

在form.py中添加RegisterForm类对给出表单处理类：

class RegisterForm(forms.Form): # 不能为空 email = forms.EmailField(required=True) password = forms.CharField(required=True, min_length=6， max_length=20) # 出错信息 captcha = CaptchaField(error_messages={"invalid":u"验证码错误"})

以下为对应的前端代码，其中添加了了django的模版用法，均以{% %}的形式在html中加入逻辑， 避免了python代码的直接插入，方便维护和修改。

<form id="email_register_form" method="post" action="{% url 'register' %}" autocomplete="off"> <div class="form-group marb20 {% if register_form.errors.email %}errorput{% endif %}"> <label>邮&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;箱</label> <input type="text" id="id_email" name="email" value="{{ register_form.email.value }}" placeholder="请输入您的邮箱地址" /> </div> <div class="form-group marb8 {% if register_form.errors.password %}errorput{% endif %}"> <label>密&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;码</label> <input type="password" id="id_password" name="password" value="{{ register_form.password.value }}" placeholder="请输入6-20位非中文字符密码" /> </div> <div class="form-group marb8 captcha1 {% if register_form.errors.captcha %}errorput{% endif %}"> <label>验&nbsp;证&nbsp;码</label> {{ register_form.captcha }} </div> <div class="error btns" id="jsEmailTips">{% for key,error in register_form.errors.items %}{{ error }}{% endfor %} {{ msg }}</div> <div class="auto-box marb8"> </div> <input class="btn btn-green" id="jsEmailRegBtn" type="submit" value="注册并登录" /> {% csrf_token %} </form>

{% csrf_token %}是django为了在用户提交表单时防止跨站攻击所做的保护，在表单最后没有加入的话，不能正常提交
表单中有一项为验证码，在django中可以使用django-simple-captcha模块实现：

url(r'^captcha/', include(‘captcha.urls')) 配置url
{{ register_form.captcha }} 配置前端

邮箱验证：

在users.py中添加了邮箱验证的model：

class EmailVerifyRecord(models.Model): # 验证码 code = models.CharField(max_length=20, verbose_name=u"验证码") email = models.EmailField(max_length=50, verbose_name=u"邮箱") # 包含注册验证和找回验证 send_type = models.CharField(verbose_name=u"验证码类型", max_length=10, choices=(("register",u"注册"), ("forget",u"找回密码"))) send_time = models.DateTimeField(verbose_name=u"发送时间", default=datetime.now) class Meta: verbose_name = u"邮箱验证码" verbose_name_plural = verbose_name def __unicode__(self): return '{0}({1})'.format(self.code, self.email)

在setting.py中添加配置邮箱信息：

EMAIL_HOST = "smtp.163.com" # 服务器EMAIL_PORT = 25 # 一般情况下都为25EMAIL_HOST_USER = "abc@163.com" # 账号EMAIL_HOST_PASSWORD = "password" # 密码EMAIL_USE_TLS = False # 一般都为FalseEMAIL_FROM = "abc@163.com" # 邮箱来自

创建utils包，新建email_send .py

from random import Random # 用于生成随机码 from django.core.mail import send_mail # 发送邮件模块from users.models import EmailVerifyRecord # 邮箱验证modelfrom MxOnline.settings import EMAIL_FROM # setting.py添加的的配置信息# 生成随机字符串def random_str(randomlength=8): str = '' chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789' length = len(chars) - 1 random = Random() for i in range(randomlength): str+=chars[random.randint(0, length)] return strdef send_register_email(email, send_type="register"): email_record = EmailVerifyRecord() # 将给用户发的信息保存在数据库中 code = random_str(16) email_record.code = code email_record.email = email email_record.send_type = send_type email_record.save() # 初始化为空 email_title = "" email_body = "" # 如果为注册类型 if send_type == "register": email_title = "注册激活链接" email_body = "请点击下面的链接激活你的账号:http://127.0.0.1:8000/active/{0}".format(code) # 发送邮件 send_status = send_mail(email_title, email_body, EMAIL_FROM, [email]) if send_status: pass

然后将用户变为活跃用户，加入相关的view：

class ActiveUserView(View): def get(self, request, active_code): # 用code在数据库中过滤处信息 all_records = EmailVerifyRecord.objects.filter(code=active_code) if all_records: for record in all_records: email = record.email # 通过邮箱查找到对应的用户 user = UserProfile.objects.get(email=email) # 激活用户 user.is_active = True user.save() else: return render(request, "active_fail.html") return render(request, "login.html")

配置生成页面的url：

url(r'^active/(?P<active_code>.*)/$', ActiveUserView.as_view(), name="user_active"), # 提取出active后的所有字符赋给active_code

至此，便可将is_active加入到登陆的限制当中：

if user.is_active: login(request, user) # 调用login方法登陆账号 return render(request, "index.html") else: return render(request, "login.html", {"msg": u"用户未激活"})
