作者	怎样编写实时获取其它网页内容的WEB PAGE?
gus 发贴: 0 积分: 0	于 2003-06-16 04:06 请问，怎样编写实时获取其它网页内容的WEB PAGE?例如，我要取得YAHOO的股票价格。有没有个例子看一看？

Yes, it has a link for daily quote. Fetch the info from below


package quote;

import java.util.*;
import utils.*;

public class YahooQuoteServer implements QuoteServer
{
    public String getURL(KeyPairs quoteParams)
    {
        String startDate = quoteParams.getStringValue(START_DATE, "");
        String endDate   = quoteParams.getStringValue(END_DATE, "");
        String stockSymbol = quoteParams.getStringValue(STOCK_SYMBOL, "");
        String scale       = quoteParams.getStringValue(TIME_INTERVAL, "d"); //default to daily

        if (!checkDateFormat(startDate) || !checkDateFormat(endDate))
        {
            return WRONG_DATE_FORMAT;
        }
        StringTokenizer ssDate = new StringTokenizer(startDate, "/");
        StringTokenizer seDate = new StringTokenizer(endDate, "/");
        String sMonth = ssDate.nextToken();
        String sDay   = ssDate.nextToken();
        String sYear  = ssDate.nextToken();
        String eMonth = seDate.nextToken();
        String eDay   = seDate.nextToken();
        String eYear  = seDate.nextToken();

        String returnURL = new String("http://chart.yahoo.com/");
        returnURL += "table.csv?&s=" + stockSymbol;
        returnURL += "&a=" + sMonth + "&b=" + sDay + "&c=" + sYear;
        returnURL += "&d=" + eMonth + "&e=" + eDay + "&f=" + eYear;
        returnURL += "&g=" + scale + "&q=q&y=0&z=" + stockSymbol + "&x=.csv";

        return returnURL;

    }

    // This will check the string to be in the format of XX/XX/XXXX
    // where X is a digit 0-9
    public static boolean checkDateFormat(String s)
    {
        String num = "0123456789";

        if (s.length() != 10) return false;
        if (num.indexOf(s.charAt(0)) == -1) return false;
        if (num.indexOf(s.charAt(1)) == -1) return false;
        if (s.charAt(2) != '/') return false;
        if (num.indexOf(s.charAt(3)) == -1) return false;
        if (num.indexOf(s.charAt(4)) == -1) return false;
        if (s.charAt(5) != '/') return false;
        if (num.indexOf(s.charAt(6)) == -1) return false;
        if (num.indexOf(s.charAt(7)) == -1) return false;
        if (num.indexOf(s.charAt(8)) == -1) return false;
        if (num.indexOf(s.charAt(9)) == -1) return false;
        return true;
    }
}

How to get it?

Ignore that, just use the code to figure out the url link to the quote.

It's my own package. I used to get daily quote from yahoo.
