WEB表单
CSRF_ENABLED = True SECRET_KEY = ‘you-will-never-guess‘
from flask import Flask app = Flask(__name__) app.config.from_object(‘config‘) from app import views
from flask.ext.wtf import Form from wtforms import StringField, BooleanField from wtforms.validators import DataRequired class LoginForm(Form): openid = StringField(‘openid‘, validators=[DataRequired()]) remember_me = BooleanField(‘remember_me‘, default=False)
<!-- extend from base layout --> {% extends "base.html" %} {% block content %} <h1>Sign In</h1> <form action="" method="post" name="login"> {{form.hidden_tag()}} <p> Please enter your OpenID:<br> {{form.openid(size=80)}}<br> </p> <p>{{form.remember_me}} Remember Me</p> <p><input type="submit" value="Sign In"></p> </form> {% endblock %}
from flask import render_template from app import app from .forms import LoginForm # index view function suppressed for brevity @app.route(‘/login‘, methods = [‘GET‘, ‘POST‘]) def login(): form = LoginForm() return render_template(‘login.html‘, title = ‘Sign In‘, form = form)

修改base.html
<html> <head> {% if title %} <title>{{title}} - microblog</title> {% else %} <title>microblog</title> {% endif %} </head> <body> <div>Microblog: <a href="/index">Home</a></div> <hr> {% with messages = get_flashed_messages() %} {% if messages %} <ul> {% for message in messages %} <li>{{ message }} </li> {% endfor %} </ul> {% endif %} {% endwith %} {% block content %}{% endblock %} </body> </html>
{% for error in form.openid.errors %} <span style="color: red;">[{{ error }}]</span> {% endfor %}<br>
OPENID_PROVIDERS = [ { ‘name‘: ‘Google‘, ‘url‘: ‘https://www.google.com/accounts/o8/id‘ }, { ‘name‘: ‘Yahoo‘, ‘url‘: ‘https://me.yahoo.com‘ }, { ‘name‘: ‘AOL‘, ‘url‘: ‘http://openid.aol.com/<username>‘ }, { ‘name‘: ‘Flickr‘, ‘url‘: ‘http://www.flickr.com/<username>‘ }, { ‘name‘: ‘MyOpenID‘, ‘url‘: ‘http://lnkdel.openid.org.cn/‘ }]
修改登录route，文件app/views.py
@app.route(‘/login‘, methods=[‘GET‘, ‘POST‘]) @oid.loginhandler def login(): if g.user is not None and g.user.is_authenticated: return redirect(url_for(‘index‘)) form = LoginForm() if form.validate_on_submit(): session[‘remember_me‘] = form.remember_me.data return oid.try_login(form.openid.data, ask_for=[‘nickname‘, ‘email‘]) return render_template("login.html", title=‘Sign In‘, form=form, providers=app.config[‘OPENID_PROVIDERS‘])
修改app/templates/login.html
<!-- extend base layout --> {% extends "base.html" %} {% block content %} <script type="text/javascript"> function set_openid(openid, pr) { u = openid.search(‘<username>‘) if (u != -1) { // openid requires username user = prompt(‘Enter your ‘ + pr + ‘ username:‘) openid = openid.substr(0, u) + user } form = document.forms[‘login‘]; form.elements[‘openid‘].value = openid } </script> <h1>Sign In</h1> <form action="" method="post" name="login"> {{ form.hidden_tag() }} <p> Please enter your OpenID, or select one of the providers below:<br> {{ form.openid(size=80) }} {% for error in form.openid.errors %} <span style="color: red;">[{{error}}]</span> {% endfor %}<br> |{% for pr in providers %} <a href="javascript:set_openid(‘{{ pr.url }}‘, ‘{{ pr.name }}‘);">{{ pr.name }}</a> | {% endfor %} </p> <p>{{ form.remember_me }} Remember Me</p> <p><input type="submit" value="Sign In"></p> </form> {% endblock %}
下面就是我们登录界面的一个截图:
最后，下一篇将引入数据库来描述Flask中数据库的使用。
