Question

我是API的新手，我正在尝试从史基浦机场的API导入数据。首先，我在查询中尝试了此链接，但后来得到了以下结果。

https://api.schiphol.nl/public-flights/flights?app_id=////APPID////&app_key=////APPKEY////&includedelays=false&page=0&sort=%2Bscheduletime

result: {code = 406; description = "Can't retrieve version number from accept-header";}

我认为我必须使用CURL来获得结果，但我不知道如何在SWIFT 3中做到这一点。

CURL: curl -X GET --header "Accept: application/json" --header "ResourceVersion: v3" "https://api.schiphol.nl/public-flights/flights?app_id=////APPID////&app_key=////APPKEY////&includedelays=false&page=0&sort=%2Bscheduletime"

我的代码现在看起来像这样：

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


    let url = NSURL(string: "https://api.schiphol.nl/public-flights/flights?app_id=////APPID////&app_key=////APPKEY////&scheduledate=2017-07-11&airline=CND&includelays=false&page=0&sort=%2Bscheduletime")!

    let task = URLSession.shared.dataTask(with: url as URL) { (data, response, error) -> Void in
        if let urlContent = data {
            do{
            let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: JSONSerialization.ReadingOptions.mutableContainers)
            print(jsonResult)
            } catch{
                print("failed")
            }
        }
    }
    task.resume()
}

有人可以帮帮我吗？

Answer 1

而不是简单的URL使用URLRequest并添加标题字段。

这是与CURL语法相当的Swift：

let url = URL(string: "https://api.schiphol.nl/public-flights/flights?app_id=xxxxxxx&app_key=yyyyyyyyyyyyy5&scheduledate=2017-07-11&airline=CND&includelays=false&page=0&sort=%2Bscheduletime")!
var request = URLRequest(url: url)
request.addValue("v3", forHTTPHeaderField: "ResourceVersion")

let task = URLSession.shared.dataTask(with: request) { (data, response, error) -> Void in ...

我将个人数据设为匿名。

注意：不要在JSONSerialization中传递任何选项，选项.mutableContainers在Swift中完全没用。

let jsonResult = try JSONSerialization.jsonObject(with: urlContent)

根据API文档，您需要在呼叫的标头中设置ResourceVersion。

以下内容应该有效：

    var req = URLRequest.init(url: URL.init(string: "https://api.schiphol.nl/public-flights/flights?app_id=//APPID//&app_key=//APPKEY//")!)
    req.setValue("v3", forHTTPHeaderField: "ResourceVersion")

    URLSession.shared.dataTask(with: req) { (data, response, error) in
        print(try? JSONSerialization.jsonObject(with: data!, options: .init(rawValue: 4)))
    }.resume()
