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

 1 from flask import Flask
 2 from flask_restful import Api
 3 from api.users.users_views import UserApi,UsersApi
 4 
 5 app = Flask(__name__)
 6 api = Api(app)
 7 
 8 api.add_resource(UsersApi, '/users/')
 9 api.add_resource(UserApi, '/users/<name>/')
10 
11 @app.route('/')
12 def hello_world():
13     return 'Hello World!'
14 
15 if __name__ == '__main__':
16     app.run()
17 #host='0.0.0.0',port=8080

2.module.py

 1 list1 = [
 2     {'name':'test', 'mail':'123@123.com', 'passwd':'123456', 'phone':'110110110'}
 3 ]
 4 #get users list
 5 def get_users():
 6     return list1
 7 #add a user
 8 def add_users(info):
 9     username = info['name']
10     a = test(username)
11     if a == 1:
12         return 'already have!'
13     else:
14         list1.append(info)
15         return 'add!'
16 #get a user
17 def get_user(username):

25             del(list1[i])
26             return 'done!'
27 #exist test
28 def test(username):
29     for i in range(len(list1)):
30         if username in list1[i].values():
31             t = 1
32             return t
33 #change a user
34 def change_user(info):
35     username = info['name']
36     usermail = info['mail']
37     userpasswd = info['passwd']
38     userphone = info['phone']
39     b = test(username)
40     if b != 1:
41         return 'no one'
42     else:
43         delete_user(username)
44         dict1 = {}
45         dict1['name'] = username
46         dict1['mail'] = usermail
47         dict1['passwd'] = userpasswd
48         dict1['phone'] = userphone
49         list1.append(dict1)
50         return 'changed!'

3.view.py

 1 from flask_restful import reqparse, Resource
 2 from flask import request,jsonify
 3 import api.users.users_modules as modules
 4 
 5 parser = reqparse.RequestParser()
 6 parser.add_argument('name', type=str, required=True, help="Can't be empty!")
 7 parser.add_argument('mail')
 8 parser.add_argument('passwd')
 9 parser.add_argument('phone')
10 
11 class UsersApi(Resource):
12     def get(self):
13             result = modules.get_users()
14             return jsonify(result)
15     def post(self):
16         data = parser.parse_args()
17         result = modules.add_users(data)
18         return jsonify(result)
19     def put(self):
20         data = parser.parse_args()
21         result = modules.change_user(data)
