Django下载文件

 服务器端：

f = open(filename)

data = f.read() f.close() response = HttpResponse(data,mimetype='application/octet-stream') response['Content-Disposition'] = 'attachment; filename=%s' % filename return response

用户端： 

#coding=utf-8 import urllib,time,datetime,urllib2,cookielib,json import time,random,datetime from poster.encode import multipart_encode from poster.streaminghttp import register_openers def getData(): obj = {} obj['param'] = 'value' register_openers() datagen, headers = multipart_encode(obj) request = urllib2.Request('http://[url]', datagen, headers) result = urllib2.urlopen(request).read() fl = open('test.png','wb')#一定是wb，不然会保存不成功 fl.write(result) fl.close() if __name__ == '__main__': getData()
