1、Flask-restful

　　参考文档

#!/usr/bin/env python
#coding:utf8
from flask import Flask,request
from flask.ext.restful import Resource,Api,reqparse,abort
import json

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

todos = {
    '1' : {'task':'build an API'},
    '2' : {'task':'build a web'},
    '3' : {'task':'build a app' }
}

# 资源不存在时的返回
def abort_if_todo_doesnt_exist(todo_id):
    if todo_id not in todos:
        abort(404,message="todo {} doesn't exist".format(todo_id))

# 获取传入的变量task值
parser = reqparse.RequestParser()
parser.add_argument('task',type=str)

# 资源的查、改、删,需要传入id
class Todo(Resource):
    def get(self,todo_id):
        abort_if_todo_doesnt_exist(todo_id)
        return {todo_id:todos[todo_id]}

    def put(self,todo_id):
        abort_if_todo_doesnt_exist(todo_id)
        args = parser.parse_args()
        print args 
        task = {'task':args['task']}  # request.args.get('task')
        todos[todo_id] = task
        return {todo_id:todos[todo_id]},201
        
    def delete(self,todo_id):
        abort_if_todo_doesnt_exist(todo_id)
        del todos[todo_id]
        return '',204

# 资源的查所有 添加,不需要传入id
class TodoList(Resource):
    def get(self):
        return todos

    def post(self):
        args = parser.parse_args()
        todo_id = str(int(max(todos))+1)
        todos[todo_id] = {'task':args['task']}
        return todos[todo_id],201

# 定义两个场景的访问路由
api.add_resource(Todo,'/<string:todo_id>')
api.add_resource(TodoList,'/')

if __name__ == '__main__':
    app.run(host='0.0.0.0',port=7777,debug=True)

2、ansible

　　Ansible — 安装部署及基本命令

　　Ansible — 快速上手

3、jsonrpc api 

　　jsonrpc api参考文档

#服务端
#!/usr/bin/env python                                                                                                                                        
#coding:utf-8
from flask import Flask,render_template,request
from flask_jsonrpc import JSONRPC
import json

app = Flask(__name__)
jsonrpc = JSONRPC(app, '/api')


@jsonrpc.method('user.create')        #响应有不定参数传入的method，最常用
def user(**kwargs):
    data = {}
    data['name'] = kwargs.get('name',None)
    data['age'] = kwargs.get('age',None)
    return 'I am  %s,age is %s' % (data['name'],data['age'])

if __name__=='__main__':
    app.debug=True
    app.run(host='0.0.0.0',port=5001)

#客户端
#!/bin/env python
# -*- encoding: utf-8 -*-
from __future__ import unicode_literals
import json
import requests

headers = {'content-type': 'application/json'}
url = "http://127.0.0.1:5001/api"
data = { 
    'jsonrpc':'2.0',
    'method': 'user.create',      #请求后端不定参数的method
    'id':'1',
    'params':{
        'name':'wd',   #无参数的method，此处为空，指定参数的method，只能保留一条参数                                                                         
        'age':'18'
    }   

}

r = requests.post(url, headers=headers,json=data)

print r.status_code
print r.text

4、zabbix api

　　zabbix api

zabbix登录接口是咧
import requests
import json

headers = {'content-type': 'application/json'}
url = "http://123.59.185.96/zabbix/api_jsonrpc.php"

def zabbix_login():
        data = {
            'jsonrpc':'2.0',
            'method': 'user.login',     
            'id':'1',
            'params':{
                'user':'admin',   
                'password':'zabbix'
            }
        }
        r = requests.post(url, headers=headers,json=data)
        return r.text

def tokens():
    token = json.loads(zabbix_login())['result']
    return token 

def hostlist():
    data = {
             'jsonrpc':'2.0',
             'method':'host.get',
             "params": {
             "output": "extend",
              "filter": {
                    "host": [
                        "Zabbix server",
                        "Linux server"
                    ]
                }
            },
            "auth": tokens(),
            "id": 1
 
    }
    
    r = requests.post(url, headers=headers,json=data)
    return r.text


print hostlist()

5、token
