json - 快速解析API对JSON的响应

将API响应字符串解析为JSON时出错。下面是我的JSON响应

下面是我的代码

Alamofire.request(url).responseString { response in
        guard response.result.isSuccess,

        let data = response.result.value else
        {
            print("Error while fetching tags: \(String(describing: response.result.error))")
            completion(nil)
            return
        }

    completion(data)

以下是我的模特班：

class DealModelRootClass : NSObject, NSCoding{

var data : DealDataModelRootClass!
var msg : String!
var status : Int!

init(fromJson json: JSON!){
    if json.isEmpty{
        return
    }
    let dataJson = json["data"]
    if !dataJson.isEmpty{
        data = DealDataModelRootClass(fromJson: dataJson)
    }
    msg = json["msg"].stringValue
    status = json["status"].intValue
}


func toDictionary() -> [String:Any]
{
    var dictionary = [String:Any]()
    if data != nil{
        dictionary["data"] = data.toDictionary()
    }
    if msg != nil{
        dictionary["msg"] = msg
    }
    if status != nil{
        dictionary["status"] = status
    }
    return dictionary
}


@objc required init(coder aDecoder: NSCoder)
{
    data = aDecoder.decodeObject(forKey: "data") as? DealDataModelRootClass
    msg = aDecoder.decodeObject(forKey: "msg") as? String
    status = aDecoder.decodeObject(forKey: "status") as? Int
}


func encode(with aCoder: NSCoder)
{
    if data != nil{
        aCoder.encode(data, forKey: "data")
    }
    if msg != nil{
        aCoder.encode(msg, forKey: "msg")
    }
    if status != nil{
        aCoder.encode(status, forKey: "status")
    }

}
}

我读过很多博客，但无法解决此问题。
我不熟悉iOS。

最佳答案

首先使用转换响应，

let JSON = try! JSONSerialization.data(withJSONObject: yourResponseFromApi , options: JSONSerialization.WritingOptions.prettyPrinted)

转换api响应后，
然后您可以对其进行解码。

let decode = try! JSONDecoder().decode(YourModelClass.self, from: JSON)
