python 2.7

  1. 先装easy install

    https://pypi.Python.org/pypi/setuptools#downloads 可以下载,在win7 cmd下用python ez_setup.py安装

  2. 也可以装个IPython shell Http://arcHive.ipython.org/release/

  3. 后自动补全的Pyreadline https://pypi.python.org/pypi/pyreadline

  4.  提供http post支持的multipartposthandler https://pypi.python.org/packages/2.7/M/MultipartPostHandler2/

    windows cmd下 >easy_install MultipartPostHandler2-0.1.5-py2.7.egg

  5. pip 安装和管理 Python 包的工具 , 是 easy_install 的一个替换品

    https://pip.pypa.io/en/latest/installing.html >python get-pip.py

  6. 新的包格式wheel https://pypi.python.org/pypi/wheel >pip install --user wheel

  7.  http request https://pypi.python.org/pypi/requests/  >pip install requests


一些例子:

#!/usr/bin/python2.7


import sys

import os

import JSON

import MultipartPostHandler 

import urllib2

import requests

import time

import telnetlib


bridgeip = '192.168.0.166'

targetlamp = []

base_url = 'http://'+bridgeip+'/api/'+username

config_url = base_url + '/config'


path = os.getcwd()

print('filepath = ' + path)

#使用MultipartPostHandler

def postBridge():

    log('Posting reset firmware file to the bridge')

    filepath = os.path.join(path, 'FirmwareBridge', 'reset', 'rel.fw') #looks in the directory ../<script execution dir>/FirmwareBridge/reset/ for rel.fw

    opener = urllib2.build_opener(MultipartPostHandler.MultipartPostHandler)

    params = {'fileupload' : open(filepath, 'rb')}

    opener.open('http://'+bridgeip+'/updater', params)

    log( 'Bridge is restarting ...')

    time.sleep(60)

#使用requests

def setBridgeVersion(bridgeVersion):

    log('Posting firmware file to the bridge')

    filepath = os.path.join(path, 'FirmwareBridge', bridgeVersion, 'rel.fw')

    #filepath = os.path.join(path, 'FirmwareBridge', bridgeVersion, 'prod.fw')

    firmwareBridge = {'firmwarefile' : open(filepath, 'rb')}

    fileuploadurl = 'http://'+bridgeip+'/updater'

    response = requests.post(fileuploadurl, files=firmwareBridge)

    print response.text

    time.sleep(60)

#httpget,json操作

def fillLighsArray():

    r = requests.get(base_url)

    config = r.text

    configjson = json.loads(config)

    lights = json.dumps(configjson['lights'])

    lightsjson = json.loads(lights)


    for i in range(1,len(lightsjson)+1):

        targetlamp.append(i)

#http put

def setPortalServices(set_value):

    body = '{"portalservices":' + set_value + '}'           

    r = requests.put(config_url,body)

    log(  "Setting portal services to [" + set_value + "] : " + r.text)


检查ping结果

def pingHost(host):

p = subprocess.Popen("ping -n 1 "+ host,

stdin = subprocess.PIPE,

stdout = subprocess.PIPE,

stderr = subprocess.PIPE,

shell = True,

bufsize = 0)

(stdoutput,erroutput) = p.communicate() 

regex = re.compile("Minimum = (\d+)ms, Maximum = (\d+)ms, Average = (\d+)ms", re.IGNORECASE)

print("find %d\n",len(regex.findall(stdoutput)))

if len(regex.findall(stdoutput)) > 0:

#print host+': Host Up!'

return True

else:

#print host+': Host Down!'

return False
