  5      * 接口:http://hq.sinajs.cn/list=sh601006这个url会返回一串文本,例如:
  6      * 
  7      * var hq_str_sh601006="大秦铁路, 27.55, 27.25, 26.91, 27.55, 26.20, 26.91,

 11      * 
 12      * 这个字符串由许多数据拼接在一起,不同含义的数据用逗号隔开了,按照程序员的思路,顺序号从0开始。 0:”大秦铁路”,股票名字;
 13      * 1:”27.55″,今日开盘价; 2:”27.25″,昨日收盘价; 3:”26.91″,当前价格; 4:”27.55″,今日最高价;
 14      * 5:”26.20″,今日最低价; 6:”26.91″,竞买价,即“买一”报价; 7:”26.92″,竞卖价,即“卖一”报价;
 15      * 8:”22114263″,成交的股票数,由于股票交易以一百股为基本单位,所以在使用时,通常把该值除以一百;
 16      * 9:”589824680″,成交金额,单位为“元”,为了一目了然,通常以“万元”为成交金额的单位,所以通常把该值除以一万;
 17      * 10:”4695″,“买一”申请4695股,即47手; 11:”26.91″,“买一”报价; 12:”57590″,“买二”
 18      * 13:”26.90″,“买二” 14:”14700″,“买三” 15:”26.89″,“买三” 16:”14300″,“买四”
 19      * 17:”26.88″,“买四” 18:”15100″,“买五” 19:”26.87″,“买五”
 20      * 20:”3100″,“卖一”申报3100股,即31手; 21:”26.92″,“卖一”报价 (22, 23), (24, 25),
 21      * (26,27), (28, 29)分别为“卖二”至“卖四的情况” 30:”2008-01-11″,日期; 31:”15:05:32″,时间;
