flask学习(1)

1.基本框架

from flask import Flask
app = Flask(__name__)@app.route('/')
def hello():return "<h1>Hello, Flask in Conda!</h1>"if __name__ == '__main__':app.run(host='0.0.0.0', port=5000, debug=True)  # 关键行！

在此基础上

from flask import Flask
app = Flask(__name__)@app.route('/hello', methods = ['GET', 'POST'])
def hello():return "<h1>Hello, Flask in Conda!</h1>"@app.route('/hi', methods = ['POST'])
def hi():return "hi hi"if __name__ == '__main__':app.run(host='0.0.0.0', port=5000, debug=True)  # 关键行！

变成这样访问是因为@app.route变了。methods方法决定访问的方式，如果有GET可以直接跳转。
