我是 swift 新手,我也在尝试使用 Alamofire 从 API 调用数据。我对如何使用 PUT 请求 来更新数据感到很困惑。我已经在 SO 中阅读了一些解决方案,但我不知道我将如何应用到我的应用程序中。我正在创建一个Event App,场景应该是,当参与者点击Check In按钮时,它会将registered_flag
更新为true
的意思参与者将被标记为已注册,按钮将更改为 checkout 。我真的不知道我的 API 服务是否正确。希望你能帮助我。非常感谢。
事件参与者的 JSON 中的注册标志应在 checkInOutButton 后更新一次
{
"event_name": "Q & A",
"event_participants": [
{
"participant_id": "70984656-92bc-4c36-9314-2c741f068523",
"employee_number": null,
"last_name": "Surname",
"first_name": "FirstName",
"middle_name": null,
"display_name": "Surname, FirstName ",
"department_name": "Medical Informatics",
"position_name": "Application Developer",
"registered_flag": true,
"registered_datetime": "2018-09-13T08:54:40.150",
"registration_type": 1,
"delete_flag": false,
"manual_reg_flag": false,
"out_flag": false,
"out_datetime": null,
"classification": 6,
"others": "Guest"
}
}
更新 JSON 以进行签到
{
"registered_flag": true,
"registration_type": 1
}
updateType
enum UpdateParticipantType: String {
case checkIn = "Check In"
case checkOut = "Check Out"
}
UpdateParticipant 的 APIService
func updateParticipant(updateType: UpdateParticipantType,
participantID: String,
successBlock: @escaping ([Attendee]) -> Void,
failureBlock: @escaping (Error) -> Void)
{
let updateParticipantURL = URL(string: "\(REGISTER_PARTICIPANT_URL)/\(updateType)/\(participantID)")
Alamofire.request(updateParticipantURL!, method: .put).responseJSON { (response) in
print(response)
if let error = response.error
{
failureBlock(error)
print(error)
return
}
if let jsonArray = response.result.value as? [[String : Any]] {
for anItem in jsonArray {
if let eventparticipants = anItem["event_participants"] as? [[String : Any]] {
var extractedAttendees = [Attendee]()
for participants in eventparticipants{
let success = Attendee.init(JSON: participants)
extractedAttendees.append(success!)
}
successBlock(extractedAttendees)
}
}
}
}
}
根据 Alamofire文档:
let parameters: Parameters = [
"foo": "bar",
"baz": ["a", 1],
"qux": [
"x": 1,
"y": 2,
"z": 3
]
]
Alamofire.request("https://httpbin.org/post", method: .post, parameters: parameters)
对于给定的 json
{
"registered_flag": true,
"registration_type": 1
}
let parameters: Parameters = [
"registered_flag": true
"registration_type": 1
]
