flask-restful

parser = reqparse.RequestParser()

这种方式采用查询字符串的方式获取前台数据

request.get_json()

这种方式采用获取json串的方式获取数据

flask-restful架构的编码结构：

flask:

        api:

            __init__.py

            module.py

            view.py

        main.py

1、main.py

from flask import Flask
from flask_restful import Api
from api.users.users_views import UserApi,UsersApi

app = Flask(__name__)
api = Api(app)

api.add_resource(UsersApi, '/users/')
api.add_resource(UserApi, '/users/<name>/')

@app.route('/')
def hello_world():
    return 'Hello World!'

if __name__ == '__main__':
    app.run()
#host='0.0.0.0',port=8080

2.module.py

list1 = [
    {'name':'test', 'mail':'123@123.com', 'passwd':'123456', 'phone':'110110110'}
]
#get users list
def get_users():
    return list1
#add a user
def add_users(info):
    username = info['name']
    a = test(username)
    if a == 1:
        return 'already have!'
    else:
        list1.append(info)
        return 'add!'
#get a user
def get_user(username):
    for i in range(len(list1)):
        if username in list1[i].values():
            return list1[i]
#delete a user
def delete_user(username):
    for i in range(len(list1)):
        if username in list1[i].values():
            del(list1[i])
            return 'done!'
#exist test
def test(username):
    for i in range(len(list1)):
        if username in list1[i].values():
            t = 1
            return t
#change a user
def change_user(info):
    username = info['name']
    usermail = info['mail']
    userpasswd = info['passwd']
    userphone = info['phone']
    b = test(username)
    if b != 1:
        return 'no one'
    else:
        delete_user(username)
        dict1 = {}
        dict1['name'] = username
        dict1['mail'] = usermail
        dict1['passwd'] = userpasswd
        dict1['phone'] = userphone
        list1.append(dict1)
        return 'changed!'

3.view.py

from flask_restful import reqparse, Resource
from flask import request,jsonify
import api.users.users_modules as modules

parser = reqparse.RequestParser()
parser.add_argument('name', type=str, required=True, help="Can't be empty!")
parser.add_argument('mail')
parser.add_argument('passwd')
parser.add_argument('phone')

class UsersApi(Resource):
    def get(self):
            result = modules.get_users()
            return jsonify(result)
    def post(self):
        data = parser.parse_args()
        result = modules.add_users(data)
        return jsonify(result)
    def put(self):
        data = parser.parse_args()
        result = modules.change_user(data)
        return jsonify(result)

class UserApi(Resource):
    def get(self,name):
        result = modules.get_user(name)
        return jsonify(result)
    def delete(self,name):
        result = modules.delete_user(name)
        return jsonify(result)
