python自带的JSON处理就OK

a = '{"GZWWWVIRUS": {"endflag": "2", "version": "RB_Virus_20150507_5", "updated_at": "2015-05-08 11:54:21"}, "BJWWWHORNBILL": {"endflag": "2", "version": "RB_Whornbill_20150507_8", "updated_at": "2015-05-08 13:45:41"}, "BJDOOTAVDOOTA": {"endflag": "2", "version": "RB_Vdoota_20150507_8", "updated_at": "2015-05-08 11:35:02"}, "GZTINTERFACEWHORNBILL": {"endflag": "2", "version": "RB_Whornbill_20150507_8", "updated_at": "2015-05-08 12:36:43"}, "GZTINTERFACESNAKE": {"endflag": "2", "version": "RB_Snake_20150507_5", "updated_at": "2015-05-08 12:35:07"}, "GZWWWHORNBILL": {"endflag": "2", "version": "RB_Whornbill_20150507_8", "updated_at": "2015-05-08 13:49:06"}, "GZWWWSNAKE": {"endflag": "2", "version": "RB_Snake_20150507_5", "updated_at": "2015-05-08 11:55:30"}}'

b = JSONDecoder().decode(a)

print b['GZWWWVIRUS']

因为客户端传递过来的数据是json数据，可以看成一个json对象。不是传过来的post表单，所以你用request.post.get('id', '')这种肯定取不到值的。 def datasave(request): dict = {} info = 'data log save success' try: if request.method == 'post': req = simplejson.loads(request.raw_post_data) username = req['username'] password = req['password'] datas = req['datas'] game_id1 = datas[0]['game_id'] except: import sys info = "%s || %s" % (sys.exc_info()[0], sys.exc_info()[1]) dict['message']=info dict['create_at']=str(ctime()) json=simplejson.dumps(dict) return httpresponse(json) request.raw_post_data表示的是从客户端发送过来的原始数据,为了纯字符串, 通过simplejson的loads方法将其转换为字典数据类型req. 上面的代码也演示了如何以json格式作为响应值, 而非html, 即通过simplejson的dumps方法, 将字典数据dict序列化为字符串形式,将通过httpresponse返回.
