使用Python Flask快速构建一个api server

使用 flask 快速构建一个api server

代码如下：

from flask import Flask, jsonify, request

app = Flask(__name__)

# 定义一个路由，当访问根路径时返回欢迎信息
@app.route('/')
def home():
    return 'Hello, this is a simple API!'

# 定义一个路由，接受GET请求并返回JSON响应
@app.route('/api/data', methods=['GET'])
def get_data():
    data = {'key': 'value'}
    return jsonify(data)

# 定义一个路由，接受POST请求并返回请求体中的数据
@app.route('/api/data', methods=['POST'])
def post_data():
    data = request.json
    return jsonify(data)

if __name__ == '__main__':
    app.run(debug=True)
