问题描述
最近在做一个项目，其中有一个模块要求是从直接从优酷上获取视频的真实地址然后在网上找了大量代码，来解析优酷视频的url地址但都有一个关键的地方，就是根据获取到的json，取其中某个键的值，可是到这一步就断章了本来就对json不了解，我把json完整代码贴出来，请各位大侠帮我取个seed和streamfiledids这两个键的值{"data":[{"ct":"s","cs":"2329|2346","logo":"http://g1.ykimg.com/1100641F4655099E80DE960933FDA47FB9AC13-522D-08F6-3596-7B486A02C6BD","seed":7486,"tags":["u5dddu85cfu7ebf","u62fcu8f66","u5305u8f66","u7a3bu57ceu4e9au4e01","u7c73u5806u51b0u5ddd","u81eau9a7e","u5faeu4fe1uff1a360000318"],"categories":"88","videoid":"228681853","vidEncoded":"XOTE0NzI3NDEy","username":"u5dddu85cfu5947u5175u4ff1u4e50u90e8","userid":"154402212","title":"u897fu884cu6f2bu8bb0u5dddu85cfu7ebf","up":2,"down":0,"ts":"oIhb5jkK4R4zK9k7AdBjupI","tsup":"oIhfgzoK4R4zK9k7ArVnupI","preview":{"thumbs":["0521000255099EDF6C1E25475406A2C6","0521010255099EDF6C1E25475406A2C6"],"sectiontime":"6000","host":"http://g3.ykimg.com/"},"key1":"bd70c8ca","key2":"3917d3a75f1c412a","tt":"0","ip":1987729206,"ep":"NAXSRwQWI77d2PbH9uJxVoLyuhY51wrDXBY=","videoSource":"1","seconds":"791.61","streamfileids":{"3gphd":"59*38*59*59*11*59*59*35*59*59*37*37*59*20*23*35*31*65*27*65*35*41*59*20*38*38*8*17*39*21*27*59*41*41*38*27*17*18*60*39*35*27*27*60*37*11*65*8*60*27*27*35*35*60*20*20*17*18*31*23*21*18*35*37*38*39*","flv":"59*38*59*59*59*11*59*11*59*59*37*37*59*20*23*35*37*31*27*65*35*41*59*20*38*38*8*17*39*21*27*59*41*41*38*27*17*18*60*39*35*27*27*60*37*11*65*8*60*27*27*35*35*60*20*20*17*18*31*23*21*18*35*37*38*39*","mp4":"59*38*59*59*59*27*59*11*59*59*37*37*59*20*27*27*35*39*27*65*35*41*59*20*38*38*8*17*39*21*27*59*41*41*38*27*17*18*60*39*35*27*27*60*37*11*65*8*60*27*27*35*35*60*20*20*17*18*31*23*21*18*35*37*38*39*","hd2":"59*38*59*59*59*35*59*37*59*59*37*37*59*20*27*18*41*39*27*65*35*41*59*20*38*38*8*17*39*21*27*59*41*41*38*27*17*18*60*39*35*27*27*60*37*11*65*8*60*27*27*35*35*60*20*20*17*18*31*23*21*18*35*37*38*39*","hd3":"59*38*59*59*27*59*59*65*59*59*37*37*59*20*20*41*23*17*27*65*35*41*59*20*38*38*8*17*39*21*27*59*41*41*38*27*17*18*60*39*35*27*27*60*37*11*65*8*60*27*27*35*35*60*20*20*17*18*31*23*21*18*35*37*38*39*"},"segs":{"3gphd":[{"no":"0","size":"29763629","seconds":792,"k":"68b1eb78c1c038ea24122ee6","k2":"16711c1fb5d2715da"}],"flv":[{"no":"0","size":"14993808","seconds":418,"k":"b94fe81dcd916d9b282a6d6f","k2":"10f152238444df915"},{"no":"1","size":"13320549","seconds":374,"k":"45ff17b9c400345a282a6d6f","k2":"1ba7f35efed585fc1"}],"mp4":[{"no":"0","size":"24867377","seconds":384,"k":"6f40e7fef4512719282a6d6f","k2":"1688e961ad5f9a387"},{"no":"1","size":"29465751","seconds":408,"k":"21ec715f4c03cef1261e4e2b","k2":"173a08249b1fe12c0"}],"hd2":[{"no":"0","size":"21376484","seconds":190,"k":"8188cce7ea06302b261e4e2b","k2":"1519a030d29c750bf"},{"no":"1","size":"32811618","seconds":194,"k":"973b48febd8f1142282a6d6f","k2":"1839f6382b99a02fd"},{"no":"2","size":"36896826","seconds":185,"k":"22a6646fcd6a0641261e4e2b","k2":"1c52660ab390f439c"},{"no":"3","size":"12637867","seconds":104,"k":"667b625915b9a229261e4e2b","k2":"18a3da498cbb68a3f"},{"no":"4","size":"14921113","seconds":119,"k":"16cd5ec8027cc6e624122ee6","k2":"15d62e43db6742888"}],"hd3":[{"no":"0","size":"30886746","seconds":138,"k":"3570c8371868fd2a261e4e2b","k2":"1a97c6ed09ad3e1bd"},{"no":"1","size":"31956022","seconds":145,"k":"ec0b23c38c24aae524122ee6","k2":"1e211d127ebe5a2e7"},{"no":"2","size":"58352773","seconds":126,"k":"a31e2739acdc52ee282a6d6f","k2":"10a0af7a914a9f6b0"},{"no":"3","size":"46330722","seconds":140,"k":"9523ff55ed7426b424122ee6","k2":"1338c111d790aac89"},{"no":"4","size":"35148463","seconds":128,"k":"290a4746dca32b9a24122ee6","k2":"17f1dc8fefbe9c323"},{"no":"5","size":"28229840","seconds":115,"k":"2d4e87893205965e261e4e2b","k2":"1c9bc7255dd49e530"}]},"streamsizes":{"3gphd":"29763629","flv":"28314357","mp4":"54333128","hd2":"118643908","hd3":"230904566"},"stream_ids":{"3gphd":"289704293","flv":"289703897","mp4":"289733794","hd2":"289740022","hd3":"289762856"},"streamlogos":{"3gphd":1,"flv":1,"mp4":1,"hd2":1,"hd3":1},"streamtypes":["3gphd","flv","mp4","hd2","hd3"],"streamtypes_o":["hd2","flvhd","mp4","3gphd","hd3"]}],"user":{"id":0,"acc_support":true},"controller":{"search_count":true,"mp4_restrict":1,"stream_mode":2,"video_capture":true,"hd3_enabled":false,"area_code":510100,"dma_code":4134,"continuous":0,"playmode":"normal","circle":false,"tsflag":false,"other_disable":false,"xplayer_disable":false,"app_disable":false,"share_disabled":false,"download_disabled":false,"pc_disabled":false,"pad_disabled":false,"mobile_disabled":false,"tv_disabled":false,"comment_disabled":false}}{"data":[{"ct":"s","cs":"2329|2346","logo":"http://g1.ykimg.com/1100641F4655099E80DE960933FDA47FB9AC13-522D-08F6-3596-7B486A02C6BD","seed":5851,"tags":["u5dddu85cfu7ebf","u62fcu8f66","u5305u8f66","u7a3bu57ceu4e9au4e01","u7c73u5806u51b0u5ddd","u81eau9a7e","u5faeu4fe1uff1a360000318"],"categories":"88","videoid":"228681853","vidEncoded":"XOTE0NzI3NDEy","username":"u5dddu85cfu5947u5175u4ff1u4e50u90e8","userid":"154402212","title":"u897fu884cu6f2bu8bb0u5dddu85cfu7ebf","up":2

解决方案
解决方案二：
自己先顶下，解析的时候要不要把data去掉呢
解决方案三：
定义一个对象，只包含你想要的字段，然后序列化就行了
解决方案四：
你是用什么来解析?jquery还是C#程序？如果是jquery那就是vardataInfo=JSON.parse(对象);然后用dataInfo.data.seed试试,如果是用C#那就用Network.JOSN.dll试试
解决方案五：
用.net，但在序列化时，报错，说有一些无效字符，也是找了好多方法，有思路，就是在写代码的时候，太纠结了
解决方案六：
可以用Newtonsoft.Json.dll这个来试试解析
解决方案七：

.netframework其实并没有提供完整的所谓json解析功能，它只是在.net内存对象与输出的string之间进行“json序列化、反序列化”。使用Newtonsoft可以得到JObject、JArray、JToken等等数据结构，使用它才可以灵活地处理json数据。
解决方案八：
可以用json.net或者windows.data.json接卸json字符串，看下这个链接http://james.newtonking.com/archive/2012/09/14/json-net-vs-windows-data-json
解决方案九：
先存在stringbuild中，然后来解析
解决方案十：
眼睛花了,太多了
解决方案十一：
来，爷是人肉读码机！首先下载引用Newtonsoft.Json.dlldynamicjsonObj=JsonConvert.DeserializeObject("你那一串json字符串");varseed=jsonObj.data[0].seed;var3gphd=jsonObj.data[0].streamfileids.3gphd;varflv=jsonObj.data[0].streamfileids.flv;varmp4=jsonObj.data[0].streamfileids.mp4;顺带一提，lz的JSON粘贴了两遍啦，解析方然报错，删掉其中一个之后解析成功。太长不好读什么的，试试在线json解析http://www.bejson.com/jsonviewernew/
