网站建设第七天注册用户邮件激活
标签
网站建设很早前就有了注册登录登出功能。只是没有添加邮箱认证环节。今天来添加上。
注册认证的步骤如下：
1.首先用户经过一般的注册程序(signup)。这时候，还没有激活。
2.网站后台发送一封带激活链接的邮件到注册用户邮箱。
3.用户登录邮箱点击链接,网站后台user_actice方法进行处理，将用户usr.is_active置为True.
后台django代码
首先在urls.py添加url
url(r'^signup$',base.signup,name='signup'), url(r'^user_active/([a-zA-Z]+)$',base.user_active,name='user_active'),
base.py添加相关处理方法

后端setting.py邮箱设置
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST= 'smtp.mail.bnu.edu.cn' EMAIL_PORT= 25 EMAIL_HOST_USER = '201421140020@mail.bnu.edu.cn' #Mailbox的名称 EMAIL_HOST_PASSWORD = '*****' #Mailbox的密码 默认有SMTP服务 EMAIL_SUBJECT_PREFIX = '[yefan.site]' #邮件标题前缀,默认是'[django]' EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = SERVER_EMAIL = '201421140020@mail.bnu.edu.cn' #发件人的邮箱地址
前端js代码
<script type="text/javascript"> $(function(){ $("#register").submit(function(event) { var $state=$(".state"); var username=$("#id_username").val(); var email=$("#id_email").val(); var password=$("#id_password").val(); var repeat_password=$("#id_repeat_password").val(); //验证注册信息是否正确 if (email==""){ $state.text("邮箱不能为空!"); return false; } if(!email.match(/^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+((\.[a-zA-Z0-9_-]{2,3}){1,2})$/)){ $state.text('请输入正确的邮箱格式!'); return false; } if(username==""){ $state.text("用户名不能为空!") return false; } if(password=="" || repeat_password==""){ $state.text("密码为空!"); return false; } if(password.length<6){ $state.text("密码少于6位!"); return false; } if(password!==repeat_password){ $state.text("两次密码不一致!"); return false; } //注册 $state.text('注册中，请稍后...'); $.ajax({ type: "POST", data: $('#register').serialize(), url: "{% url 'signup' %}", cache: false, dataType: "json", success: function(json, textStatus){ var is_success = json['success']; if(is_success){ $state.text('注册成功，请去邮箱激活...'); window.setTimeout(function(){ window.location.reload(); },3000); }else{ $state.text(json['state']); }; }, error: function (XMLHttpRequest, textStatus, errorThrown) { $state.text("注册出错，请重试 "+errorThrown); } }); return false; }); }) </script>
signup.html部分，显示注册状态还有注册表单
<div style="text-align:center"> <h3 class="state" style="color:#FFCC00">{{state}}</h3> </div>
