}通过127.0.0.1:5000/login/访问到页面
输入想要插入的数据
# 引入Flask
from flask import Flask, request
# 引入pymysql操作数据库
import pymysql
app = Flask(__name__)
@app.route('/login/', methods=['GET', 'POST'])
def getinfo():
# 获取表单传输过来的数据,nmae是用户名字段，pwd是密码字段
name = request.values.get("usernmae") # 打印请求的表单数据
pwd = request.values.get('password')# 数据库连接
conn = pymysql.connect(
host='127.0.0.1',
port=3306,
user='root',
password='123456',
database='day48', # 创建的数据库为day48
charset='utf8'
)
# sql执行语句，创建的表名为userinfo
sql = 'insert into userinfo(username,password) values(%s,%s)'
# 生成游标对象
cursor = conn.cursor()
# 执行sql语句
cursor.execute(sql, (name, pwd))
# 提交插入的数据
conn.commit()
return '插入数据成功'
# 执行
app.run()但页面显示插入数据成功，代表数据插入到数据库当中
通过navicat查看插入的数据
