Question

我有一个数据生成项目，我需要将生成的数据与另一个变量相匹配。

例如。曼联 - 利物浦队回归英超联赛巴萨 - 真正的马德里回归西甲

我需要使用switch case方法generateLeague，它应该对类MatchEvent中的String匹配变量起作用。我所做的编码似乎没有捕获生成的MatchEvent匹配值，也没有返回字符串作为String leagueName = generateLeague没有收到String。它表示BetEvent中的generateLeague（String）无法应用。

这是具有数据生成的MatchEvent类（这确实有效）。

from bs4 import BeautifulSoup

soup = BeautifulSoup('<BR><CENTER><TABLE BORDER=1 CELLPADDING=0 NOSAVE><TR ALIGN=CENTER NOSAVE><TD COLSPAN="4" NOSAVE><CENTER><B>Summary Table</B></CENTER><TR><TD>Testname</TD><TD>Status</TD><TD>Link to HTML
</TD><TD>Utility</TD></TR><TR><TD>test1</TD><TD>FAIL</TD><TD><A HREF= abc.html>HTML_report</a></BR></TD><TD>run</TD></TR><TR><TD>31Jan2017_03h12m52s</TD><TD>FAIL</TD><TD><A HREF=def.html>HTML_report</a></BR></TD
><TD>run_2</TD></TR></TABLE></CENTER><BR>')

for link in soup.find_all('a'):
    link['href'] = 'fix the absolute path here %s' % (link.get('href'),)

print soup.prettify()

这是使用Switch case语句的generateLeague方法。

    /**
 * Mock a transaction for testing purposes
 */
public MatchEvent generateEvent() {
    try {
        DataFactory df = new DataFactory();

        // BetEvent
        int betID = df.getNumberBetween(220000000, Integer.MAX_VALUE);
        float odds = df.getNumberBetween((int) 1.05, 30);
        // Selections
        String selectionID = UUID.randomUUID().toString();
        // Market
        // Event
        String eventID = UUID.randomUUID().toString();
        String match = df.getItem(StaticTestData.match, 80, "Liverpool vs Manchester Utd"); // should match league and categoryID
        //SubCategory
        // category
        final int categoryID = 1;       // LeagueID by number eg. 1 is for LaLiga, should match MatchLeague and Match
        final String categoryName = "Football";
        // Subcategory
        String subCategoryID = UUID.randomUUID().toString();
        String leagueName = generateLeague();      // should match Match and category ID
        final String parentSubCategory = null;
        // market
        final String name = null;
        float matchOdds = df.getNumberBetween((int) 1.05, 30);  // since focusing on prematch should keep maxNo 20?
        //betEvent
        float stake = df.getNumberBetween(0, 1200);
        boolean mobile = Math.random() < 0.5;
        final String providerName = "EPBetsSportsbook";
        float totalOdds = matchOdds;
        float totalStake = stake;
        String nation = df.getItem(StaticTestData.countryCodes);     // should make it as realistic as possible
        final String currency = "EUR";


        Date date = new Date();
        java.text.DateFormat formatter = new java.text.SimpleDateFormat("MM-dd-yyyy");
        String calendarDate = formatter.format(date);

        return new MatchEvent(betID, odds, selectionID, eventID, match, categoryID, categoryName, subCategoryID,
                leagueName, parentSubCategory, name, matchOdds, stake, mobile, providerName,
                totalOdds, totalStake, nation, date, currency, calendarDate);


    } catch (Exception e) {

        // For demo purposes, we are not going to log errors/send to a kafka stream

        throw e;
    }
}

我将非常感谢并提前感谢您的任何指导。

Answer 1

如果String匹配中没有空格，那么club将为null。然后它当然不会正常切换。你需要在if语句中添加else语句。您也可能希望确保俱乐部是小写的。像这样：

if (match.toLowerCase().contains(" ")) {
    club = match.toLowerCase().substring(0, match.indexOf(" "));
} else {
    club = match.toLowerCase();
}

另一件事：在generateEvent中：你有generateLeague（）。这不会编译。做generateLeague（匹配）;

Answer 2

String leagueName = generateLeague没有收到String。它说无法应用BetEvent中的generateLeague（String）。

它之所以如此，是因为您的generateLeague方法需要String参数

public static String generateLeague(String match)
{
   //content
}

但是从generateEvent方法

调用它时

String leagueName = generateLeague();

您不在String方法中传递generateLeague作为参数。

切换机箱不返回字符串
