json字符串解析
{"1":{"SID":"1","RDATE":"19","$ROW_NUM$":"0","$TABLE_CODE$":"MG_REMARK","RCONTENT":"223","RUSERID":"12","TYPEBY":"2","RID":"1","$PK_CODE$":"1`2`1","RSTATE":"1","RIP":"123"}},{"5":{"SID":"1","RDATE":"19","$ROW_NUM$":"1","$TABLE_CODE$":"MG_REMARK","RCONTENT":"223","RUSERID":"12","TYPEBY":"2","RID":"5","$PK_CODE$":"5`2`1","RSTATE":"1","RIP":"123"}}
这个json串怎么解析呢，比如我想获得里面的RDATE的值。（其中"1","5"都是从数据库中获取的主键它们都是变化的）
