模板渲染其实就是静态文件的展示
app.py
import os
from flask import Flask, render_template, jsonify
app = Flask(__name__)
@app.route('/')
def home():
return 'flask home2'
@app.route('/index/')
def index():
# #返回字符串
# return '<b>flask home2</b>'
# #模板渲染
return render_template('index.html', name='小新')
# # #返回json
# # jsonify: 将字典转换为json格式
# return jsonify({'name': '小新', 'age': 18})
if __name__ == '__main__':
# print(f"Starting server on port {os.environ.get('FLASK_RUN_PORT', 'not set')}")
# app.run(debug=True, port=5001, host='0.0.0.0')
port = 8884
print(f"Starting Flask server on port {port}")
app.run(debug=True, port=port, host='0.0.0.0')
