Moya是对Alamofire的再次封装。
我们用一张图来对比一下Alamofire和moya的区别:

有关Alamofire
为了对Moya有更好的了解。让我们先复习一下Alamofire的用法。
Alamofire 使用一个简单的Get请求 请求城市的实时天气为例子
代码语言:javascript复制let weatherUrl:String = "http://weatherapi.market.xiaomi.com/wtr-v2/temp/realtime?cityId="
代码语言:javascript复制func getWeatherInfo() -> Void {
let parameters = ["cityId":"101040100"];
Alamofire.request(weatherUrl,method:.get,parameters:parameters,encoding: URLEncoding.default).responseJSON { (response) in
switch response.result {
case .success(let json ):
let jsonDic = json as? NSDictionary
print(jsonDic! as NSDictionary);
self.showAlert(weatherDic: jsonDic!)
break
case .failure(let error):
print("error:(error)")
break
}
}
}
Moya的简单实用
封装一个Api Provider
代码语言:javascript复制//
// NetworkManager.swift
// SwiftPlayground
//
// Created by Destiny on 2020/8/18.
// Copyright © 2020 Destiny. All rights reserved.
//
import UIKit
import Moya
import HandyJSON
// NetworkAPI就是一个遵循TargetType协议的枚举
let NetworkProvider = MoyaProvider<NetworkAPI>()
enum NetworkAPI {
// 实时天气
case realtimeWeather(cityId:String)
}
extension NetworkAPI:TargetType{
public var baseURL: URL{
switch self {
case .realtimeWeather:
return URL(string: "http://weatherapi.market.xiaomi.com/wtr-v2/temp/realtime?cityId=")!
}
}
// 对应的不同API path
var path: String {
switch self {
case .realtimeWeather: return ""
}
}
// 请求类型
public var method: Moya.Method {
return .get
}
// 请求任务事件(这里附带上参数)
public var task: Task {
var parmeters: [String : Any] = [:]
switch self {
case .realtimeWeather(let cityId):
parmeters = ["cityId":cityId] as [String : Any]
return .requestParameters(parameters: parmeters, encoding: URLEncoding.default)
}
}
// 是否执行Alamofire验证
public var validate: Bool {
return false
}
// 这个就是做单元测试模拟的数据,只会在单元测试文件中有作用
public var sampleData: Data {
return "{}".data(using: String.Encoding.utf8)!
}
// 请求头
public var headers: [String: String]? {
return nil
}
}
网络请求方法
代码语言:javascript复制/// 基本使用
func weatherAPI() {
NetworkProvider.request(NetworkAPI.realtimeWeather(cityId: "101040100")) { result in
if case .success(let response) = result {
// 解析数据
let jsonDic = try! response.mapJSON() as! NSDictionary
self.showAlert(weatherDic: jsonDic)
}
}
}
代码语言:javascript复制func showAlert(weatherDic:NSDictionary) -> Void {
let dataDic = weatherDic["weatherinfo"] as! NSDictionary
let temp = dataDic["temp"] as!String
let sd = dataDic["SD"] as!String
let alertController = UIAlertController(title:"提示",message:"重庆当前温度:(temp)℃,湿度:(sd)",preferredStyle: .alert);
let canceAction = UIAlertAction(title:"取消",style:.cancel,handler:nil);
let okAciton = UIAlertAction(title:"确定",style:.default,handler: {
action in
print("他点击了确定")
})
alertController.addAction(canceAction);
alertController.addAction(okAciton);
self.present(alertController, animated: true, completion: nil)
}
