Flask框架第二天：注册和登录 

# coding=utf-8
from flask import Flask, render_template
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import DataRequired, EqualTo

app = Flask(__name__)

app.config["SECRET_KEY"] = "akfsakfassdkjsakdwnm"


class RegisterForm(FlaskForm):
    user_name = StringField(label=u"用户名", validators=[DataRequired(u"用户名不能为空")])
    password = PasswordField(label=u"密码", validators=[DataRequired(u"密码不能为空")])
    password2 = PasswordField(label=u"确认密码", validators=[DataRequired(u"确认密码不能为空"), EqualTo("password", u"两次密码不一致")])
    submit = SubmitField(label=u"提交")


@app.route("/register")
def register():
    form = RegisterForm()
    return render_template("register.html", form=form)


if __name__ == '__main__':
    app.run(debug=True)

　　

render_template模块：调用模板
flask_wtf模块：表单
wtforms模块：安装flask_wtf时自动安装，不用另外安装，
StringField 字符串，
PasswordField 密码，
SubmitField 提交操作
DataRequired模块：验证表单项
