ios - 无法使用 AlamoFire 和 SwiftyJSON 解析 JSON

Question

我坚持使用 AlamoFire 和 SwiftyJSON 为 iOS 解析 JSON。我有一个像这样的 JSON:

[{"id":23561,"name":"RFI - Persan رادیو صدای Ùرانسه Ùارسی","country":"FR","image":{"url":null,"thumb":{"url":null}},"slug":"rfi-persan-رادیو-صدای-Ùرانسه-Ùارسی","website":"rfi","twitter":"","facebook":"","categories":[{"id":21,"title":"News","description":"","slug":"news","ancestry":"4"}],"streams":[{"stream":"http://rfi-persan.scdn.arkena.com/rfienpersan.mp3","bitrate":0,"content_type":"audio/mpeg","status":1}],"created_at":"2016-01-12T07:52:08+01:00","updated_at":"2016-08-02T01:52:50+02:00"}]

这是我到目前为止尝试过的方法，但不起作用:

func loadSomeJSONData() {
        Alamofire.request(.GET, "http://example.com/json/")
            .responseJSON { (_, _, data, _) in
                let json = JSON(data!)
                if let Name = json["name"].string {
                    println("name: \(firstName)") // Name should equal "RFI"
                }
        }
    }

但出于某种原因，它没有从 json 对象中获取名称。

非常感谢!

你的json是Array不是Dictionary，所以这样访问json

if let arr = json.arrayObject as? [[String:AnyObject]] { 
    if let name = arr[0]["name"] as? String {
        println("name: \(name)") // Name should equal "RFI"
    }
}
