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

• APIManager

  enum APIManager {
      case testApi
      case testApiPara(para1:String,para2:String)
      case testApiDict(Dict:[String:Any])
      case getNbaInfo(getKey:String)
  }
  
  extension APIManager:TargetType {
      var baseURL: URL {
          return URL.init(string: "http://op.juhe.cn/onebox/basketball/")!
      }
  
      var path: String {
          switch self {
          case .testApi:
              return "nba"
          case .testApiPara(let para1, let para2):
              return "nba"
          case .testApiDict:
              return "nba"
          case .getNbaInfo:
              return "nba"

      }
  
      var method: Moya.Method {
          switch self {
          case .testApi:
              return .get
          default:
              return .post
          }
      }
  
      var sampleData: Data {
          return "".data(using: String.Encoding.utf8)!
      }
  
      var task: Task {
          switch self {
          case .testApi:
              return .requestPlain
          case let .testApiPara(para1, _):
              return .requestParameters(parameters: ["key" : para1], encoding: URLEncoding.default)
          case .testApiDict(let dict):
              return .requestParameters(parameters: dict, encoding: JSONEncoding.default)
          case .getNbaInfo(let getKey):
              return .requestParameters(parameters: ["key" : getKey], encoding: URLEncoding.default)
          }
      }
  
      var headers: [String : String]? {
          return ["Content-Type":"application/x-www-form-urlencoded"]
      }
  }

• RxHandyJSON

      case RequestFailed
      case NoResponse
      case UnexpectedResult(resultCode: Int?,resultMsg:String?)
  }
  
  enum RequestStatus: Int {
      case requestSuccess = 200
      case requestError
  }
  
  fileprivate let RESULT_CODE = "code"
  fileprivate let RESULT_MSG = "reason"
  fileprivate let RESULT_DATA = "result"
  
  public extension Observable {
      func mapResponseToObject<T: HandyJSON>(type: T.Type) -> Observable<T> {
          return map { response in
              guard let response = response as? Moya.Response
                  else {
                      throw DCUError.NoResponse
              }
              guard ((200...209) ~= response.statusCode) else {
                  throw DCUError.RequestFailed
              }
  
              let jsonData = try response.mapJSON() as! [String : Any]
              if let code = jsonData[RESULT_MSG] as? String {
                  if code == "查询成功" {
                      if let model = JSONDeserializer<T>.deserializeFrom(dict: jsonData){
                          return model
                      }
                  }
              }
  }

• TestModel

  //
  //  TestModel.swift
  //  SwiftNetWorkHelper
  //

  //
  
  import HandyJSON
  
  struct TestModel: HandyJSON {
      var reason :String = ""
      var result :String = ""
  }

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

Demo链接

• 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
