Flask实战第45天：完成前台登录界面

我们的注册页面和登录页面有很多相似之处，因此，也可以基于一个模板来实现。

首先创建一个模板html,命名为front_signbase.html，

然后修改注册页面front_signup.html，继承front_signbase.html

{% extends 'front/front_signbase.html' %}

{% block title %}注册-BBS论坛{% endblock %}

{% block h2_block %}注册BBS论坛{% endblock %}

{% block form_content %}
    <div class="form-group">
                <div class="input-group">
                    <input type="text" class="form-control" name="telephone" placeholder="手机号码">
                    <span class="input-group-btn">
                        <button id="sms-captcha-btn" class="btn btn-default">发送验证码</button>
                    </span>
                </div>
            </div>
    <div class="form-group">
        <input type="text" class="form-control" name="sms_captcha" placeholder="短信验证码">
    </div>
    <div class="form-group">
        <input type="text" class="form-control" name="username" placeholder="用户名">
    </div>
    <div class="form-group">
        <input type="password" class="form-control" name="password1" placeholder="密码">
    </div>
    <div class="form-group">
        <input type="password" class="form-control" name="password2" placeholder="确认密码">
    </div>
    <div class="form-group">
        <div class="input-group">
            <input type="text" class="form-control" name="graph_captcha" placeholder="图形验证码">
            <span class="input-group-addon captcha-addon">
                <img  id="captcha-img" src="{{ url_for('common.graph_captcha') }}">
            </span>
        </div>
    </div>
    <div class="form-group">
        <button class="btn btn-warning btn-block" id="submit-btn">立即注册</button>
    </div>
{% endblock %}

front_signup.html

新建注册页面front_signin.html,继承front_signbase.html

{% extends 'front/front_signbase.html' %}

{% block title %}登录-BBS论坛{% endblock %}

{% block h2_block %}登录BBS论坛{% endblock %}

{% block form_content %}
    <div class="form-group">
        <input type="text" class="form-control" name="telephone" placeholder="手机号码">
    </div>
    <div class="form-group">
        <input type="password" class="form-control" name="password" placeholder="密码">
    </div>
    <div class="checkbox">
        <label>
            <input type="checkbox" name="remember" value="1">记住我
        </label>
    </div>
    <div class="form-group">
        <button class="btn btn-warning btn-block" id="submit-btn">立即登录</button>
    </div>
    <div class="form-group">
        <a href="{{ url_for("front.signup") }}" class="signup-link">没有账号？立即注册</a>
        <a href="#" class="resetpwd-link" style="float:right;">找回密码</a>
    </div>
{% endblock %}

front_signin.html

然后编写一个登录的视图，编辑front.view.py

class SignInViews(views.MethodView):
    def get(self):
        return_to = request.referrer
        if return_to and return_to != request.url and safeutils.is_safe_url(return_to):
            return render_template('front/front_signin.html', return_to=return_to)
        return render_template('front/front_signin.html')

    def post(self):
        pass
