python之basic加密http下載

實例：

import urllib2

import base64,logging

def httpDownload(testModule,var):

    testModule = testModule + '.zip'

    url = var['HttpRes'] + '/' + testModule     ########此url爲下載路徑

    request = urllib2.Request(url)

    downDir = '/home/Elves/agent/module/'

    file = downDir + testModule

    base64string = base64.encodestring('%s:%s' % (var['HttpResUSer'],var['HttpResPass'])).replace('\n','')    ######將用戶名，密碼編碼，去掉最後的回車

    request.add_header('Authorization','Basic %s' % base64string)  #####將用戶名密碼以報文頭的形式加到url

    try:

        result = urllib2.urlopen(request)

    except Exception,e:

        err = 'requestUrl_err: %s'%e

        logging.error(err)

    fp = open(file,'wb')

    fp.write(result.read())     ######將文件讀取，寫入

    fp.close()

    return 'download success'
