flask 2 进阶

# 创建项目

jinja2 语法基础

# pycharm 里面 创建 new project -->pure  python 之后选择路径 选择解释器 以及虚拟环境问题

from flask import Flask,request,redirect,render_template,jsonify,send_file
app = Flask(__name__)

一个主py文件

<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Old Boy EDU</title>

<body>
<div> _____________________________________</div>
Welcome to Old Boy EDU : student
<div>{{ student }}</div>
<table border="1px">
    <tr>
        <td>{{ student.name }}</td>

            <td>{{ student_dict[foo]["gender"] }}</td>
        </tr>
    {% endfor %}
</table>
</body>
</html>
配合的前端代码 整合

jinja2 高阶

safe : 此时你与HTML只差一个 safe
后端
from flask import Flask
from flask import render_template
app = Flask(__name__)
@app.route("/")
def index():
    tag = "<input type='text' name='user' value='DragonFire'>"
    return render_template("index.html",tag=tag)
app.run("0.0.0.0",5000)
