3. 創建app.py

from flask import Flask

app = Flask(__name__)
app.config['DEBUG'] = True

@app.route('/')
def index():
    return "hello,world"

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

4. 運行app.py

5. url傳參訪問

from flask import Flask

app = Flask(__name__)
app.config['DEBUG'] = True

@app.route('/')
def index():
    return "hello,world"

@app.route('/user/<name>')
def user(name):
    return f"hello,{name}"

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