篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了完成注册功能相关的知识，希望对你有一定的参考价值。

js文件： onclick函数return True时才提交表单，return False时不提交表单。
html文件：
1. <form>中设置 action和method="post"
2. <input> 中设置 name
主py文件中：
1. from flask import request, redirect, url_for
2. @app.route(‘/regist/‘, methods=[‘GET‘, ‘POST’])

def regist():

if request.method == ‘GET‘:

return render_template(‘regist.html‘)

else:

username = request.form.get(‘username’)#获取form中的数据

判断用户名是否存在:存在报错

不存在，存到数据库中

redirect重定向到登录页

from flask import Flask,render_template,request,redirect,url_for,session
from flask_sqlalchemy import SQLAlchemy

import config
app = Flask(__name__)
app.config.from_object(config)
db=SQLAlchemy(app)

class User(db.Model):
    __tablename__=‘user‘
    id=db.Column(db.Integer,primary_key=True,autoincrement=True)
    username=db.Column(db.String(20),nullable=False)
    password = db.Column(db.String(20), nullable=False)
    nickname = db.Column(db.String(20))
db.create_all()
@app.route(‘/‘)
def index():
    return render_template(‘index.html‘)

@app.route(‘/regist/‘,methods=[‘GET‘,‘POST‘])
def regist():
    if request.method==‘GET‘:
        return render_template(‘regist.html‘)
    else:
        usern=request.form.get(‘username‘)
        passw=request.form.get(‘password‘)
        user=User.query.filter(User.username==usern).first()
        if user:
            return u‘username existed.‘
        else:
            user1=User(username =usern,password=passw)
            db.session.add(user1)
            db.session.commit()
    return redirect(url_for(‘login‘))

if __name__ == ‘__main__‘:
    app.run()

import os

SQLALCHEMY_DATABASE_URI = ‘mysql+pymysql://root:@127.0.0.1:3306/mis_db?charset=utf8‘
