cloudstack api调用python

通过python调用cloudstack接口,cloudstack 接口通过  admin   key来判断是否有访问有权访问

#!/usr/bin/env python
import urllib2
import urllib
import hashlib
import hmac
import base64


baseurl='http://10.64.8.10:8080/client/api?'

#这个字典存放命令下的参数，这里是创建计算方案'command':'createServiceOffering',
request={
'name':'json4c8g',
'command':'createServiceOffering',
'storagetype':'shared',
'memory':'8096',
'cpunumber':'4',
'displaytext':'asdasd',
'cpuspeed':'1800',
'domainid':'1', 
}

#下面的这样写字典的方式主要是和上面有个区分，这里是必须写的参数
request['response']='json'
request['apikey']='LYohWAwKAKR_QKqM9Na02xyZ2pVSjvbrt2DRFaMrZuOs6zi9gyzxUkWtzIDSqjF-ZZ4UhD_8dIP6MG9opf3PTg'
secretkey='iO8rxr1rid29oHAO3ZiLKOoz6F6E9IWm9V2G7yUNd0zHI6XIEY0JvaBRzHo79p_dQ5NAGDCzTlk7229p4DQNKg'
request_str='&'.join(['='.join([k,urllib.quote_plus(request[k])]) for k in request.keys()])
sig_str='&'.join(['='.join([k.lower(),urllib.quote_plus(request[k].lower().replace('+','%20'))])for k in sorted(request.iterkeys())])
sig=urllib.quote_plus(base64.encodestring(hmac.new(secretkey,sig_str,hashlib.sha1).digest()).strip())

req=baseurl+request_str+'&signature='+sig

res=urllib2.urlopen(req)

#打印返回结果
print res.read()

下面就是执行返回的结果,
