Question

这是我从服务器收到的JSON响应。我试图解析这些值而没有任何成功。

{"items":
   [{"item":
     {  "id":824,
        "company_id":31,
        "config_id":45,
        "imagesmall":null,
        "imagethumb":null,
        "pointofsales":null,
        "status":true,
        "endPlanned":false
      }
   },
   {"item":
    {   "id":889,
        "company_id":74,
        .
        .
        .
        "status":true,
        "endPlanned":false
    }
  }]
}

我正在尝试的代码

if let json = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? [String: Any]{ 
    print(json) // does work 
    let item = json?["items"] as? [[String: Any]] 
    print(item?[0]) // does work 
    // ... from here I am looking for the code to access the values and print it out ... 
}

要打印item，您需要遍历items数组。

if let json = try? JSONSerialization.jsonObject(with: data!, options: []) as? [String: Any],
   let items = json["items"] as? [[Strin:Any]] {

     for item in items {
         if let dic = item["item"] as? [String:Any] {
             print(dic["id"])
             print(dic["company_id"])
             print(dic["config_id"])
             //and so on..
         }
     }
}

注意：使用Swift本机类型时，无需使用（反）序列化指定选项。

如何解析Swift 3中这个JSON响应的值？
