最近,我尝试使用freshOS/网络 https://github.com/freshOS/Networking快捷的包裹。
我读了好几次自述文件,但无法让它与我一起工作。我正在尝试获取使用公共 API 服务的国家/地区列表,这就是我所做的:
Model
import Foundation
import Networking
struct CountryModel: Codable {
let error: Bool
let msg: String
let data: [Country]
}
struct Country: Codable {
let name: String
let Iso3: String
}
extension Country: NetworkingJSONDecodable {}
extension CountryModel: NetworkingJSONDecodable {}
/*
Output
{
"error":false,
"msg":"countries and ISO codes retrieved",
"data":[
{
"name":"Afghanistan",
"Iso2":"AF",
"Iso3":"AFG"
}
]
}
*/
视图控制器+ 打印(数据)callAPI()
函数不打印
override func viewDidLoad() {
super.viewDidLoad()
configureUI()
callAPI()
}
fileprivate func configureUI() {
title = "Choose Country"
view.addSubview(tableView)
tableView.delegate = self
tableView.dataSource = self
tableView.frame = view.bounds
}
fileprivate func callAPI() {
let countriesService = CountriesApi()
var cancellable = Set<AnyCancellable>()
countriesService.countries().sink(receiveCompletion: { completion in
switch completion {
case .finished:
print("finished") // not printing
break
case .failure(let error):
print(error.localizedDescription)
}
}) { data in
print(data) // not printing
self.countriesData = data
}.store(in: &cancellable)
}
国家API()
struct CountriesApi: NetworkingService {
let network = NetworkingClient(baseURL: "https://countriesnow.space/api/v0.1")
// Create
func create(country c: Country) -> AnyPublisher<Country, Error> {
post("/countries/create", params: ["name" : c.name, "Iso3" : c.Iso3])
}
// Read
func fetch(country c: Country) -> AnyPublisher<Country, Error> {
get("/countries/\(c.Iso3)")
}
// Update
func update(country c: Country) -> AnyPublisher<Country, Error> {
put("/countries/\(c.Iso3)", params: ["name" : c.name, "Iso3" : c.Iso3])
}
// Delete
func delete(country c: Country) -> AnyPublisher<Void, Error> {
delete("/countries/\(c.Iso3)")
}
func countries() -> AnyPublisher<[CountryModel], Error> {
get("/countries/iso")
}
}
我希望有人能帮助我解决我所缺少的事情。
