使用 Alamofire 和 SwiftyJSON 难以解析 JSON

Question

我写了下面的代码：

Alamofire.request("\(NSLocalizedString("base_url", comment: ""))\(NSLocalizedString("url_rateCard", comment: ""))").responseJSON{response in
    let status:Int = (response.response?.statusCode)!
    switch status{
    case 200:
        switch response.result{
            case .success(let suc):
                let json = JSON(suc)
                print(json)
                self.rateCardCollectionView.delegate = self
                self.rateCardCollectionView.dataSource = self
                break
        case .failure(let error):
                print(error)
                break
        }
        break
    default:
        print("Could not call ratecard api")
        break
    }
}

我得到了这个结果：

{
  "error" : null,
  "data" : [
    {
      "name" : "Air Conditioner 1.5ton",
      "unit" : "piece",
      "_id" : "58d3c7a277d862536fb5ec2e",
      "itemComment" : "Mentioned price is subjected to change on vendor visit.",
      "price" : 1450,
      "icon" : "\/images\/rate-card\/undefined-1490685861277.png"
    },
...

请查看 json，特别是图标字段。它应该是这样的：

"icon": "/images/rate-card/undefined-1490685861277.png",

该字符串在键数组的第一个字典中 data:

let json = JSON(suc)
if let icon = json["data"][0]["icon"].string {
    print(icon)
}

或者如果你想打印数组中的所有 icons

let json = JSON(suc)
if let data = json["data"].array {
   for item in data {
       if let icon = item["icon"].string {
          print(icon)
       }
   }
}
