打造swift网络框架
准备工作
-
使用CocoaPods工具Pod需要使用的相关框架
具体的pod用法在这里就不做详解了，如有不懂可以查阅 CocoaPods使用
pod 'Alamofire'
pod 'Moya/RxSwift'
pod 'HandyJSON', '~> 5.0.0-beta.1'
创建文件

}
实现效果
let rxProvider = MoyaProvider<APIManager>()
rxProvider.rx.request(.getNbaInfo(getKey: "537f7b3121a797c8d18f4c0523f3c124")).asObservable().mapResponseToObject(type: TestModel.self)
.subscribe { (test) in
print(test)
let model = test.element
print(model?.reason ?? String.self)
}
.disposed(by: disposeBag)
总结
-
APIManager作为接口内容配置，通过接口地址以及接口数据的组建
-
RxHandyJSON作为由于Moya对HandyJson没有扩展，自己实现的扩展，该文件可以根据后台接口定义做调整
-
TestModel作为基础数据格式，该处可以创建一个BaseModel，根据后台返回数据进行调整，会有更好的扩展性
