[英]How Can I make & send array of dictionary (JSON Format ) send to server using Alamofire in swift 3
I have tried to create & send array of dictionary JSON format to Alamofire. 我尝试创建字典JSON格式的数组并将其发送到Alamofire。
{
"attendance": [{
"attndid":"0",
"psngrtype": "student",
"date":currentdate,
"cuid": "25",
"enttid": "21",
}] }
Here, I am used tableview, In the above "cuid" & "enttid" I giving value from selectable tableview cell data. 在这里,我使用了tableview,在上面的“ cuid”和“ enttid”中,我从可选tableview单元格数据中给出了值。 remaining are constant.
其余的都是常数。 I am passing one array of dictionary, if i select one tableview cell data.
如果我选择一个tableview单元格数据,则传递一个字典数组。 and two array, if i select two cells.etc.. and I am using below code and I get but getting issue create dictionary format.
和两个数组,如果我选择两个单元格等。我正在使用下面的代码,但得到的问题是创建字典格式。 My code:
我的代码:
let arrayOfDictionaries: [[String:AnyObject]] =
[
["psngrtype":"student" as AnyObject,
"attndid": "0" as AnyObject ,
"cuid":stdpasngerid as AnyObject,
"enttid": entitID as AnyObject,
"attnddate":CurrentDate as AnyObject ]]
print(arrayOfDictionaries.toJSONString())
extension Collection where Iterator.Element == [String:AnyObject] {
func toJSONString(options: JSONSerialization.WritingOptions = .prettyPrinted) -> String {
if let arr = self as? [[String:AnyObject]],
let dat = try? JSONSerialization.data(withJSONObject: arr, options: options),
let str = String(data: dat, encoding: String.Encoding.utf8) {
return str
}
return "[]"
} }
output: 输出:
[{
"enttid" : "1",
"psngrtype" : "student",
"attnddate" : "10-26-2017",
"attndid" : "0",
"cuid" : "25" }]
And I want to add first one like json format.and add multiple array if i select more than one tableview cell. 我想添加第一个像json格式。如果我选择多个tableview单元,则添加多个数组。 Please help i am stuck?
请帮我卡住吗?
Simply you can do 只需您即可
var finalArray:[String:String] = [:]
finalArray["Attandance"] = arrayOfDictionaries.toJSONString()
Object Mapping, you can use ObjectMapper library.
对象映射,可以使用ObjectMapper库。
Create object Attendance like 创建像这样的对象出勤
class Attendance: Mappble {
var objects: [AttendancesAttributes] = []
init () { }
required init?(map:Map) { }
func mapping(map: Map){
objects <- map["attendance"]
}
}
Then creates your AttendancesAttributes object 然后创建您的AttendancesAttributes对象
class AttendancesAttributes: Mappable {
var id: String
....
func mapping(map: Map) {
//do the mapping with your dictionary
}
}
Then in your VC I guess you can do 然后,在您的VC中,我想您可以
var attendance: Attendance = Attendance()
func (_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
//check if your object is or not in your array.
attendance.objects.append(yourTableViewFeeder[indexPath.row])
}
and finally in your API Client: 最后在您的API客户端中:
func sendAttendanceInformationsToServer(attendance: Attendance) {
Alamofire.request(url, method, parameters: attendance.toJSON(), encoding: JSONEncoding.default, headers: ["":""]).responseJSON (completionHandler: { //deal your response here
})
}
