首先数据库长这样
我们想将name和age列显示到web页面
上代码sqlshowweb.py
from flask import Flask
from flask import render_template
import pymysql
app = Flask(__name__)
@app.route('/')
def index():
conn = pymysql.connect(host='39.106.168.84', user='flask_topvj_net', password='xxxxxxxx', port=3306,
db='flask_topvj_net')
cur = conn.cursor()
sql = "SELECT `name`, `age` FROM `student` WHERE 1"
cur.execute(sql)
u = cur.fetchall()
conn.close()
return render_template('index.html',u=u)
if __name__ == '__main__':
app.debug = True
app.run(port=8003)
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table class="table table-bordered">
<tr>
<th>name</th>
<th>age</th>
</tr>
{% for i in u %}
<tr>
<td>{{ i[0] }}</td>
<td>{{ i[1] }}</td>
</tr>
{% endfor %}
</table>
</body>
</html>
运行结果
