swift - 如何根据 Swift 中的数组条目构造 alamofire 查询？

Question

我有一个类SingleUser:

class SingleUser: NSObject, NSCoding {

    var username: String
    var display_name: String
    var facebook_username: String
    var device_id: String
    .
    .
    .
}

我有一组这样的用户:

let blockedUsers: [SingleUser] = NSKeyedUnarchiver.unarchiveObject(with:
                    (defaults.object(forKey: "myUsers") as! Data)) as! [SingleUser]

我想将它与 Alamofire 一起传递到我的网络服务。

我已经定义了一些参数:

var params = [
    "long": lon as AnyObject,
    "lat": lat as AnyObject,
    "startDate": DateCalc.convertValueToDate(defaults.float(forKey: "startDate")) as AnyObject,
    "endDate": DateCalc.convertValueToDate(defaults.float(forKey: "endDate")) as AnyObject
] as [String: AnyObject]

现在我想以某种方式附加我的用户，例如如:

"users" = { 
      { "username" = "xxxx",
        "display_name" = "xxxx",
        "facebook_username" = "xxxx",
        "device_id" = "xxxx"
       },
       { "username" = "yyyy",
        "display_name" = "yyyy",
        "facebook_username" = "yyyy",
        "device_id" = "yyyy"
       },
       .
       .
       .
       }

你能告诉我如何迭代该数组并将其附加到我的 params 数组中吗？

Answer 1

class SingleUser: NSObject, NSCoding {

    var username: String
    var display_name: String
    var facebook_username: String
    var device_id: String

    var jsonFormat: [String: AnyObject] {
        return  ["username": username,
                 "display_name": display_name,
                 "facebook_username": facebook_username,
                 "device_id": device_id]
    }
}

然后:

var users = [[String: AnyObject]]()
blockedUsers.forEach { user in
    users.append(user.jsonFormat)
}
params["users"] = users
