我想解析来自alamorefire的JSON数据,如下所示。从alamofire解析JSON数据到字典数组
import UIKit
import Alamofire
import SwiftyJSON
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
Alamofire.request(.GET, "https://api.mynexttrainschedule.net/")
.responseJSON { response in
guard let object = response.result.value else {
print("Oh, no!!!")
return
}
let json = JSON(object);print(json)
let schedule = json[0]["schedule"]
}
}
}
如果我打印JSON,我有一个像下面的数据结构(简明扼要地说)。
[
{
"schedule" : [
{"departureTime" : "05:09", "destination" : "Boston", "trainType" : "Express"},
{"departureTime" : "05:19", "destination" : "Portland", "trainType" : "Rapid"},
{"departureTime" : "05:29", "destination" : "Boston", "trainType" : "Express""}
],
"station" : "Grand Central",
"direction" : "North"
},
{
"schedule" : [
{"departureTime" : "05:11","destination" : "Washington, "trainType" : "Express""},
{"departureTime" : "05:23","destination" : "Baltimore, "trainType" : "Express""},
{"departureTime" : "05:35","destination" : "Richmond, "trainType" : "Local""}
],
"station" : "Grand Central",
"direction" : "South"
}
]
现在,我该如何使用字典(出发时间,目的地...)通过或不通过SwiftyJSON保存计划数组?
谢谢。
UPDATE
下面是我自己的解决方案。
import Alamofire
import SwiftyJSON
class ViewController: UIViewController {
var scheduleArray = [Dictionary<String,String>]()
override func viewDidLoad() {
super.viewDidLoad()
Alamofire.request(.GET, "https://api.mynexttrainschedule.net/")
.responseJSON { response in
guard let object = response.result.value else {
print("Oh, no!!!")
return
}
let json = JSON(object)
if let jArray = json.array {
if let westHolidayArray = jArray[0]["schedule"].array {
for train in westHolidayArray {
if let time = train["departureTime"].string,
let dest = train["destination"].string,
let type = train["trainType"].string {
let dict = ["time":time, "dest":dest, "type": type]
self.scheduleArray.append(d)
}
}
}
}
}
}
}
谢谢。我在'.map'上得到了一个错误(上图)。它说'不能调用'地图'的类型参数列表(JSON) –
你基本上必须将你的jsonObject(服务结果)传递给函数 –
