Python+flask实现restful接口的示例详解

from flask import Flask
app=Flask(__name__)
@app.route('/HelloWorld')
def hello_world():
    return "Hello World!"
 
if __name__ == "__main__":
    app.run(host='127.0.0.1',port=8085,debug=True)

from flask import Flask,abort,request,jsonify
import requests
tasks = []
@app.route('/add_user', methods=['POST'])
def add_user():
    if not request.json  or 'id' not in request.json or 'name' not in request.json:
        abort(400)
    task = {
        'id': request.json['id'],
        'name': request.json['name']
    }
    tasks.append(task)
    return jsonify({'result': 'success'})
if __name__ == "__main__":
    app.run(host='127.0.0.1',port=8085,debug=True)

from flask import Flask,abort,request,jsonify
import requests
@app.route('/get_user', methods=['GET'])

        task = filter(lambda t: t['id'] == int(task_id), tasks)
        return jsonify(task) if task else jsonify({'result': 'not found'})
if __name__ == "__main__":
    app.run(host='127.0.0.1',port=8085,debug=True)

from flask import Flask,abort,request,jsonify
