Python实现向服务器请求压缩数据及解压缩数据的方法示例

#!/usr/bin/env python# encoding=utf-8import urllib2, httplibdef writeFile(fname, data):  f = open(fname, "w")  f.write(data)  f.close()if __name__ == '__main__':  httplib.HTTPConnection.debuglevel = 1  request = urllib2.Request('http://www.163.com/')  request.add_header('Accept-encoding', 'gzip')  # 向服务器请求压缩数据  opener = urllib2.build_opener()  f = opener.open(request)  data = f.read()     # 读取页面返回的数据  f.close()  print "压缩的数据长度为：%d" %len(data)  writeFile("a.html", data)  import StringIO, gzip  compressedstream = StringIO.StringIO(data)  gziper = gzip.GzipFile(fileobj=compressedstream)  data2 = gziper.read()  # 读取解压缩后数据  print "解压缩后数据长度为：%d" %len(data2)  writeFile("aa.html", data2)
