连接雅虎财经API获取股票信息

一直想自己做个简单的股票系统，来记录股票的价格。在网上看了下，找到google finance api、雅虎财经API、新浪财经API。没有细研究这三个之间的区别，雅虎的API从易用性以及功能方面比较适合我的要求，就定雅虎了。另外还一个web service：http://www.webxml.com.cn/WebServices/StockInfoWS.asmx。不过我利用wsdl生产客户端的时候一个异常，貌似是因为版本的问题。还没有来得急细研究，今天的重点不在这。有个帖子列出了很多不错的web service

1.获取实时数据

http://finance.yahoo.com/d/quotes.csv?s=股票名称&f=数据列选项

s — 表示股票名称，多个股票之间使用英文加号分隔，如“XOM+BBDb.TO+JNJ+MSFT”，罗列了四个公司的股票：XOM, BBDb.TO, JNJ, MSFT。

f — 表示返回数据列，如“snd1l1yr”。更详细的参见附录

2.历史数据请求

http://ichart.yahoo.com/table.csv?s=string&a=int&b=int&c=int&d=int&e=int&f=int&g=d&ignore=.csv

s — 股票名称

a — 起始时间，月

b — 起始时间，日

c — 起始时间，年

d — 结束时间，月

e — 结束时间，日

f — 结束时间，年

g — 时间周期。

Ø 参数g的取值范围：d->‘日’(day), w->‘周’(week)，m->‘月’(mouth)，v->‘dividends only’

Ø 月份是从0开始的，如9月数据，则写为08。

示例

查询浦发银行2010.09.25 – 2010.10.8之间日线数据

http://ichart.yahoo.com/table.csv?s=600000.SS&a=08&b=25&c=2010&d=09&e=8&f=2010&g=d

查看国内沪深股市的股票，规则是：沪股代码末尾加.ss，深股代码末尾加.sz。如浦发银行的代号是：600000.SS
