Заявить AppObject модель
struct AppObject: Codable {
var id: Int
var ipaFile, plistFile, imageFile: String
var name, notes: String
}
С библиотекой CodyFire многокомпонентные запросы действительно просты
Объявить вашу конечную точку
import CodyFire
struct AppController: EndpointController {
static var server: ServerURL? = nil
static var endpoint: String = "apps"
}
/// Usually separate file like App+Create.swift
extension AppController {
struct CreateAppRequest: MultipartPayload {
var ipaFile, plistFile, imageFile: Attachment
var name, note: String
public init (ipaFile: Attachment, plistFile: Attachment, imageFile: Attachment, name: String, note: String) {
self.ipaFile = ipaFile
self.plistFile = plistFile
self.imageFile = imageFile
self.name = name
self.note = note
}
}
static func create(_ payload: CreateAppRequest) -> APIRequest<AppObject> {
return request(payload: payload).method(.post)
}
}
Затем в каком-либо контроллере представления попытайтесь создать приложение на сервере
/// Replace _ with file data
let ipaFile = Attachment(data: _, fileName: "", mimeType: "ipa")
let plistFile = Attachment(data: _, fileName: "", mimeType: "plist")
let imageFile = Attachment(data: _, fileName: "", mimeType: .jpg)
let payload = AppController.CreateAppRequest(ipaFile: ipaFile,
plistFile: plistFile,
imageFile: imageFile,
name: "something",
note: "something")
AppController.create(payload).onRequestStarted {
/// it calls only if request started properly
/// start showing loading bar
}.onError { error in
let alert = UIAlertController(title: nil, message: error.description, preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .cancel))
self.present(alert, animated: true)
}.onProgress { progress in
/// show progress
}.onSuccess { appObject in
/// show success
/// here you received just created `appObject`
}
И это все, это просто работает:)
Следующий пример получения списка AppObject s
/// Separate file like App+List.swift
extension AppController {
static func list() -> APIRequest<[AppObject]> {
return request()
}
}
тогда где-то в поле зрения контроллера
AppController.list().onSuccess { appObjects in
/// `appObjects` is `[AppObject]`
}
Надеюсь, это поможет.
