Swift :足球数据API不起作用

Question

我正在尝试使用足球-data.org api。在做示例之前，我编写了一些相同的代码。但是这个api使用的是令牌，我不知道如何添加和执行。

我做了这些代码什么都没发生：

func getData(){
    let url = NSMutableURLRequest(URL: NSURL(string: "http://api.football-data.org/v1/soccerseasons/424/fixtures"))
    url.addValue("my token is here", forHTTPHeaderField: "X-Auth-Token")
    url.HTTPMethod = "GET"

    let task = NSURLSession.sharedSession().dataTaskWithRequest(url) { (data, response, error) in
        self.setLabels(data!)
    }

    task.resume()
}

func setLabels(MatchData: NSData){
    //var jsonError: NSError?

    do{
        let json = try NSJSONSerialization.JSONObjectWithData(MatchData, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary

        if let sys = json["soccerseason"] as? NSDictionary{
            if (sys["href"] as? String) != nil{
                let seasonsUrl = sys["href"] as! String

                print(seasonsUrl)
            }


        }
    }
    catch{
        //error

    }
}

我没有得到价值什么的。我是新来的。我的密码怎么了？

Answer 1

"soccerseason"在"_links"中，如下所示：

if let links = json["_links"] as? [String:AnyObject],
    sys = links["soccerseason"] as? [String:String],
    seasonsUrl = sys["href"] {
        print(seasonsUrl)
}

这是给主顾的。

我还注意到主数组中的每个字典中都有一个(实际上是同一个字典)：

if let fixtures = json["fixtures"] as? [[String:AnyObject]] {
    for fixture in fixtures {
        if let links = fixture["_links"] as? [String:AnyObject],
            sys = links["soccerseason"] as? [String:String],
            seasonsUrl = sys["href"] {
            print(seasonsUrl)
        }
    }
}

URL位于_links数组中的每个字典中的fixtures部件中：

if let fixtures = json["fixtures"] as? [[String:AnyObject]] {
    for fixture in fixtures {
        if let links = fixture["_links"] as? [String:[String:String]],
            season = links["soccerseason"],
            seasonsUrl = season["href"],
            awayTeam = links["awayTeam"],
            awayTeamUrl = awayTeam["href"] {

                print(seasonsUrl)
                print(awayTeamUrl)
        }
    }
}

在字典数组中，awayTeamName和homeTeamName与_links处于相同的水平：

if let fixtures = json["fixtures"] as? [[String:AnyObject]] {
    for fixture in fixtures {
        if let awayTeamName = fixture["awayTeamName"] as? String,
            homeTeamName = fixture["homeTeamName"] as? String {

            print(awayTeamName)
            print(homeTeamName)
        }
    }
}
