======利用google api calendar 發送SMS======
因為發送訊息,是以python程式寫成。運用Google API Calendar等工具將信息傳到Google日曆,再利用Google日曆提供手機簡訊提醒工具來達成SMS的目的。
=====安裝=====
安裝python必要套件。
(easy_install )<code>#yum install python-setuptools</code><code>#easy_install python-gflags
#easy_install httplib2
#easy_install argparse
#easy_install rfc3339
#easy_install google-api-python-client</code>
{{:linux:monitor:google_calendar.png?300|}}
=====申請使用Google API金鑰=====
因為是使用Google API,需要到 https://code.google.com/apis/console/ (使用google帳號登入)申請API金鑰。
  - 先到 service 開啟 calendar api (舊版控制台){{:linux:monitor:api_services.png?700|}}
  - 再到 API Access, 就可以找到程式所需的資訊(舊版控制台)。分別是Client ID: Client secret:  API key:等項目{{:linux:monitor:api_apiaccess.png?300|}}
  - 用python撰寫 發送訊息到API的程式,利用上面查到Client ID: Client secret:  API key分別填入以下程式內 gapi_calendar.py<code>#!/usr/bin/python
# -*- coding: utf8 -*-
import gflags
import httplib2
import sys
import time
from apiclient.discovery import build
from oauth2client.file import Storage
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.tools import run
from rfc3339 import rfc3339
FLAGS = gflags.FLAGS

FLOW = OAuth2WebServerFlow(
client_id='Your Client ID',
    client_secret='Your Client secret',
    scope='https://www.googleapis.com/auth/calendar',
    user_agent='APIProject/0.1')

# To disable the local server feature, uncomment the following line:
gflags.FLAGS.auth_local_webserver = False

# If the Credentials don't exist or are invalid, run through the native client
# flow. The Storage object will ensure that if successful the good
# Credentials will get written back to a file.

storage = Storage('/var/lib/zabbixsrv/alertscripts/calendar.dat') ==>(網址進行授權完成後,會在此路徑下產生calendar.dat)
credentials = storage.get()
if credentials is None or credentials.invalid == True:
  credentials = run(FLOW, storage)

# Create an httplib2.Http object to handle our HTTP requests and authorize it
# with our good Credentials.
http = httplib2.Http()
http = credentials.authorize(http)

# Build a service object for interacting with the API. Visit
# the Google APIs Console
# to get a developerKey for your own application.
service = build(serviceName='calendar', version='v3', http=http,
       developerKey='Your API key')

#zb_sendto = 日曆ID ,zb_title = 主旨 , zb_body= 說明
zb_sendto= sys.argv[1]
zb_title= sys.argv[2]
zb_body= sys.argv[3]
sttime = time.time()
endtime = time.time()+60*60
event = {
  'summary': zb_title,
  'location': 'QY_office',
  'description': zb_body,
  'start': {
   'dateTime': rfc3339(sttime),
  'timeZone': 'Asia/Taipei'
  },
  'end': {
    'dateTime': rfc3339(endtime),
    'timeZone': 'Asia/Taipei'

    ]
  },
}

created_event = service.events().insert(calendarId=zb_sendto, body=event).execute()
print created_event['id']
</code>
  - 執行此程式  參數1:日曆ID(google mail ) 2.標題 3.說明)<code>#python gapi_calendar.py example@gmail.com TilteTest88 contextTest88</code>
      * 使用此程式產生的**網址進行授權** 要求是否允許 使用google API 發送訊息到日曆ID{{:linux:monitor:api_cmd.png?700|}}{{:linux:monitor:api_htmlauth.png?600|}}{{:linux:monitor:api_htmlauthcode.png?300|}}
      * 貼上授權碼後完成授權 , 會在目錄下產 calendar.dat{{:linux:monitor:api_cmd2.png?700|}}
      * 送出events 後會print event id ,就完成了。{{:linux:monitor:api_cmd3.png?700|}}{{:linux:monitor:google_calendar.png?700|}}
