ios - 如何快速获取json对象的数组

Question

我想从JSON对象中获取数组

这是我的代码:

let url = URL(string:"http://192.168.0.117/rest/login.php")
        let parameters = ["email": email , "pwd":password]
        var request = URLRequest(url : url!)
        request.httpMethod = "POST"
        request.httpBody = try? JSONSerialization.data(withJSONObject:parameters, options: [])
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        let session = URLSession.shared
        session.dataTask(with: request, completionHandler: { (data, response, error) in
            if let data = data {
                do {
                    let json = try? JSONSerialization.jsonObject(with: data, options: []) as! Dictionary<String, Any>
                    if let json = json {
                        print("HERE SHOULD BE YOUR JSON OF LOGIN : \(json)")
                        let status = json["status"] as! String
                        let datas = json["data"] as! String
                        print("Here is the Data : \(datas)")                       
                        print("here LOIGN : \(status)")
                        if status == "200"
                        {
                            DispatchQueue.main.async
                                {
                                    self.performSegue(withIdentifier: "dosigninEmp", sender: self)
                            }
                        } else if status == "204"
                        {
                            self.displayMessage(userMessage: "Not Authorized User")
                        }
                    }
                }
            } else {
                print("Error \(String(describing: error?.localizedDescription))")
            }
        }).resume()

我得到的输出是:

HERE SHOULD BE YOUR JSON OF LOGIN : ["status": 200, "data": {
    "emp_id" = 1004;
    type = emp;
}, "Message": Auth Succesful]

我如何获得“类型”因为我正在获取状态并使用 segue 但现在我想获取状态以及类型以使用 segue 但我无法获得类型 任何帮助将不胜感激

我认为将您的数据转换为 json 将提供正确的 json 格式的字符串、数组和字典。这就是为什么它会在 Dictionary 中提供数据:

print("HERE SHOULD BE YOUR JSON OF LOGIN : \(json)")
let status = json["status"] as! String
let datas = json["data"] as! String
print("Here is the Data : \(datas)")                       
print("here LOIGN : \(status)")

可以将这些行改成:

var type = ""
var datas = [String: AnyObject]()
if let data = json["data"] as? [String: AnyObject], let typeStr = data["type"] as? String {
    datas = data
    type = typeStr
}
print("Here is the Data : \(datas)")                       
print("Here Type : \(type)")
