示例 - C#脚本代码采集搜狐NBA球员, 球队和比赛实况

最近 @甜瓜 (QQ:1069629945) 开发了一套NBA数据采集脚本, 我觉得很赞. 经他允许发布出来和大家分享一些经验:

球员球队: http://data.sports.sohu.com/nba/nba_team_info.php?teamid=1 .. 30

在1到30的循环中抓取球队信息, 球员信息并用id将其关联起来, 脚本如下:

public void Run()
{
Logger.ClearAll();
for(int i=1; i<=30; i++)
{
Default.Navigate("http://data.sports.sohu.com/nba/nba_team_info.php?teamid="+i);
Default.Ready();
var teamid = i;
var teamname = Default.SelectSingleNode("div.blockA>h2>span");
Logger.Log(teamname.Text());
var teamurl = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li>a");
Logger.Log(teamurl.Text());
var teamcity = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(1)");
Logger.Log(teamcity.Text().Replace("主场所在城市：",""));
var gym = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(2)");
Logger.Log(gym.Text().Replace("主体育馆：",""));
var peoplenum = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(3)");
Logger.Log(peoplenum.Text().Replace("可容纳人数：",""));
var intonba = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(4)");
Logger.Log(intonba.Text().Replace("加入NBA时间：",""));
var champion = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(5)");
Logger.Log(champion.Text().Replace("获总冠军次数：",""));
var coach = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(6)");
Logger.Log(coach.Text().Replace("现任主教练：",""));
DataManager.AppendData("TEAM",
DataEntry.Create()
.Set("teamid", teamid+"")
.Set("teamname", teamname.Text())
.Set("teamurl", teamurl.Text().Replace("主场所在城市：",""))
.Set("gym",gym.Text().Replace("主体育馆：",""))
.Set("peoplenum", peoplenum.Text().Replace("可容纳人数：",""))
.Set("intonba", intonba.Text().Replace("加入NBA时间：",""))
.Set("champion", champion.Text().Replace("获总冠军次数：",""))
.Set("coach", coach.Text().Replace("现任主教练：",""))
);
Logger.Log(i.ToString());
var playelist = Default.SelectNodes("div.tab>table tr");
foreach(var player in playelist)
{
var num = player.SelectSingleNode("TD:eq(0)");
var a = player.SelectSingleNode("TD:eq(1)>DIV:eq(0)>div>a");
var url = a.Attr("href");
var playerid = Regex.Match(url, @"\d+").Value;
var playerimageurl = player.SelectSingleNode("TD:eq(1)>DIV:eq(0)>div>a>img");
var playername = player.SelectSingleNode("TD:eq(1)>DIV:eq(0)>P:eq(0)>A");
var position = player.SelectSingleNode("TD:eq(2)>SPAN:eq(0)");
var height = player.SelectSingleNode("TD:eq(3)");
var weight = player.SelectSingleNode("TD:eq(4)");
var birth = player.SelectSingleNode("TD:eq(5)");
var college = player.SelectSingleNode("TD:eq(6)");
Logger.Log(playerimageurl.Text());
Logger.Log(playername.Text());
Logger.Log(position.Text());
Logger.Log(height.Text());
Logger.Log(weight.Text());
Logger.Log(birth.Text());
Logger.Log(college.Text());
Logger.Log(playerimageurl.Attr("src"));
Logger.Log(playerid);
DataManager.AppendData("player",
DataEntry.Create()
.Set("playerid", playerid)
.Set("teamid", teamid+"")
.Set("playername", playername.Text())
.Set("position", position.Text())
.Set("height",height.Text())
.Set("weight", weight.Text())
.Set("birth", birth.Text())
.Set("college", college.Text())
.Set("num", num.Text())
.Set("playerimageurl",playerimageurl.Attr("src"))
);
}
}
}

比赛信息: http://data.sports.sohu.com/nba/nba_schedule_by_month.php?m=2013-01&season_year=2012
脚本如下:

public void Run()

}

DataManager.AppendData("GAMESTATIC",

}

}

这里的亮点是要看48, 49两行, 这里对加时赛也进行了处理. 不是所有的比赛都有加时赛, 就算有也可以打多场(1-4场). 因此甜瓜非常细心的对这块也做了处理. 个人感觉这块代码也还是有优化的余地, 但是这种处理也非常简单直白, 一目了然, 也是很不错的.
