swift中怎么使用Alamofire+Moya+ObjectMapper

這篇文章主要介紹“swift中怎么使用Alamofire+Moya+ObjectMapper”，在日常操作中，相信很多人在swift中怎么使用Alamofire+Moya+ObjectMapper問(wèn)題上存在疑惑，小編查閱了各式資料，整理出簡(jiǎn)單好用的操作方法，希望對(duì)大家解答”swift中怎么使用Alamofire+Moya+ObjectMapper”的疑惑有所幫助！接下來(lái)，請(qǐng)跟著小編一起來(lái)學(xué)習(xí)吧！

項(xiàng)目開發(fā)中的接口比較多，在使用moya時(shí)會(huì)使用多個(gè)類，為避免一些代買的重復(fù)書寫，做了一些封裝處理，網(wǎng)絡(luò)使用Alamofire，數(shù)據(jù)解析使用Moya-ObjectMapper

• 首先是對(duì)返回?cái)?shù)據(jù)統(tǒng)一處理的模型

import ObjectMapper
import Moya

///具體問(wèn)題具體分析,應(yīng)根據(jù)接口實(shí)際返回?cái)?shù)據(jù)結(jié)構(gòu)來(lái)定
class ResponseModel: NSObject,Mappable {
    
    /// 返回碼
    var code:Int = 0
    /// 信息
    var message:String = ""
    /// 數(shù)據(jù)
    var data:Any?
    
    override init() {super.init()}
    
    init(_ code: Int, message:String, data:Any? = nil) {
        self.code = code
        self.message = message
        self.data = data
    }
    
    class func success(_ data:Any) ->ResponseModel{
        return ResponseModel(200, message: "SUCCESS", data: data)
    }
    
    class func faild(_ message:String? = "FAILD") ->ResponseModel{
        return ResponseModel(400, message: message ?? "FAILD", data: nil)
    }
    
    required init?(map: Map) {}
    
    //若接口返回的是msg，則應(yīng)當(dāng)這么寫message <- map["msg"],或則直接將屬性message修改為msg，然后msg <- map["msg"]
    func mapping(map: Map) {
        code <- map["code"]
        message <- map["message"]
        data <- map["data"]
    }
}

• 然后是對(duì)返回?cái)?shù)據(jù)的統(tǒng)一 處理工具

import Moya

class NetWorkManager {
    
    /// 處理成功的返回結(jié)果
    static func getResponse(_ success:Moya.Response) ->ResponseModel {
        var responseModel:ResponseModel = ResponseModel()
        do {
            responseModel =  try success.mapObject(ResponseModel.self)
            //這里得注意下，有時(shí)候后臺(tái)返回的數(shù)據(jù)類型無(wú)法解析，就得做其他特殊處理
            //之前遇到過(guò)，由于數(shù)據(jù)返回的編碼方式不同，導(dǎo)致無(wú)法解析，我便使用了下面的方法
//            let cfEnc = CFStringEncodings.GB_18030_2000//具體問(wèn)題具體分析哈
//            let enc = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(cfEnc.rawValue))
//            if let str = String(data: success.data, encoding: String.Encoding(rawValue: enc)), let obj = str.data(using: .utf8), let dic = try JSONSerialization.jsonObject(with: obj, options: .mutableContainers) as? [String: Any],let res = ResponseModel(JSON: dic) {
//                responseModel = res
//            }else{
//                responseModel.code = 400
//                responseModel.message = "無(wú)法解析網(wǎng)絡(luò)數(shù)據(jù)"
//            }
        }catch{
            responseModel.code = 400
            responseModel.message = "無(wú)法解析網(wǎng)絡(luò)返回?cái)?shù)據(jù)"
        }
        //TODO: 根據(jù)各自業(yè)務(wù)需求，可對(duì)一些返回結(jié)果做出特殊處理????
        if responseModel.code == 200 ,responseModel.message == "SUCCESS",responseModel.data == nil {
            responseModel.message = "沒(méi)有更多了"
        }
        return responseModel
    }
    
    /// 處理失敗的返回結(jié)果
    static func getResponse(_ error:MoyaError) ->ResponseModel {
        let responseModel:ResponseModel = ResponseModel()
        responseModel.code = 500
        responseModel.message = error.errorDescription ?? "網(wǎng)絡(luò)訪問(wèn)出錯(cuò)"
        return responseModel
    }

    /// 獲取請(qǐng)求頭
    ///
    /// - Parameter token: 是否包含token
    /// - Returns: <#return value description#>
    static func getHeaders(_ token:Bool = true) ->[String:String] {
        var result:[String:String] = ["Content-type" : "application/json"]
        if token {
            result["Token"] = "這里寫用戶的token"
        }
        result["其他key"] = "key對(duì)應(yīng)的value"
        return result
    }
}

• 再對(duì)MoyaProvider進(jìn)行擴(kuò)展

  import Moya
  import Alamofire
  
  extension MoyaProvider {
      
      static func custom(
          endpointClosure: @escaping Moya.MoyaProvider<Target>.EndpointClosure = HZJMoyaTool<Target>.endpointClosure,
          requestClosure: @escaping Moya.MoyaProvider<Target>.RequestClosure = HZJMoyaTool<Target>.requestResultClosure,
          stubClosure: @escaping Moya.MoyaProvider<Target>.StubClosure = HZJMoyaTool<Target>.stubClosure,
          callbackQueue: DispatchQueue? = nil,
          session: Moya.Session = HZJMoyaTool<Target>.session(),
          plugins: [Moya.PluginType] = HZJMoyaTool<Target>.authPlugins(),
          trackInflights: Bool = false) -> MoyaProvider{
          return MoyaProvider.init(endpointClosure: endpointClosure, requestClosure: requestClosure, stubClosure: stubClosure, callbackQueue: callbackQueue, session: session, plugins: plugins, trackInflights: trackInflights)
      }
  
      func hzj_Request(_ target: Target, callbackQueue: DispatchQueue? = .none, progress: ProgressBlock? = .none, finishBlock:@escaping ((ResponseModel)->Void)) {
          self.request(target, callbackQueue: callbackQueue, progress: progress) { (result) in
              switch result {
              case let .success(response):
                  finishBlock(NetWorkManager.getResponse(response))
              case let .failure(error):
                  finishBlock(NetWorkManager.getResponse(error))
              }
          }
      }
  }

  
  

   

• 其中的HZJMoyaTool類,其中的具體內(nèi)容，大家應(yīng)根據(jù)自己的項(xiàng)目而定

  struct HZJMoyaTool<Target: TargetType> {
      
      static func endpointClosure(for target: Target) -> Endpoint {
          let url = target.baseURL.appendingPathComponent(target.path).absoluteString
          let endpoint = Endpoint(url: url, sampleResponseClosure: {.networkResponse(200,target.sampleData)}, method: target.method, task: target.task, httpHeaderFields: target.headers)
  //            endpoint.adding(newHTTPHeaderFields:["Content-Type" : "application/x-www-form-urlencoded","ECP-COOKIE" : ""])
          return endpoint
      }
      
      static func requestResultClosure(for endpoint: Endpoint, closure: MoyaProvider<Target>.RequestResultClosure) {
          do {
              var urlRequest = try endpoint.urlRequest()
              urlRequest.timeoutInterval = 60//設(shè)置網(wǎng)絡(luò)超時(shí)時(shí)間
  //            urlRequest.cachePolicy = .returnCacheDataElseLoad
              closure(.success(urlRequest))
          } catch MoyaError.requestMapping(let url) {
              closure(.failure(MoyaError.requestMapping(url)))
          } catch MoyaError.parameterEncoding(let error) {
              closure(.failure(MoyaError.parameterEncoding(error)))
          } catch {
              closure(.failure(MoyaError.underlying(error, nil)))
          }
      }
      
      static func stubClosure(_: Target) -> Moya.StubBehavior {
  //        return Moya.StubBehavior.immediate//使用sampleData中返回的測(cè)試數(shù)據(jù)
          return Moya.StubBehavior.never
      }
      
      static func session() -> Session {
          let defaultSession = MoyaProvider<Target>.defaultAlamofireSession()
  //        let configuration = URLSessionConfiguration.default
  //        configuration.headers = defaultSession.sessionConfiguration.headers
  //        configuration.httpAdditionalHeaders = defaultSession.sessionConfiguration.httpAdditionalHeaders
          let configuration = defaultSession.sessionConfiguration
          if let path: String = Bundle.main.path(forResource: "xxx", ofType: "cer") {
              ///添加證書
              do {
                  let certificationData = try Data(contentsOf: URL(fileURLWithPath: path)) as CFData
                  if let certificate = SecCertificateCreateWithData(nil, certificationData){
                      let certificates: [SecCertificate] = [certificate]
                      let policies: [String: ServerTrustEvaluating] = ["domain": PinnedCertificatesTrustEvaluator(certificates: certificates, acceptSelfSignedCertificates: true, performDefaultValidation: true, validateHost: true)]
                      let manager = ServerTrustManager(allHostsMustBeEvaluated: false, evaluators: policies)
                      return Session(configuration: configuration, serverTrustManager: manager)
                  }
              } catch {
                  return Session(configuration: configuration)
              }
          }
          return Session(configuration: configuration)
      }
      
      static func authPlugins() -> [Moya.PluginType] {
          return []
  //        return [AccessTokenPlugin{_ in User.shared.token}]
      }
  }

  
  

   

• 最后再舉個(gè)使用例子吧 

  import Moya
  
  let LoginLogManager = MoyaProvider<LoginLogAPI>.custom()
  
  enum LoginLogAPI {
      ///添加登錄日志(type:0-web 1-app)
      case addLoginLog(type:Int)
      ///子模塊，將部分接口抽離出去
      case childApi(child:ChildAPI)
  }
  
  extension LoginLogAPI:TargetType {
      var baseURL: URL {
          switch self {
          case . childApi(child: let child):
              return child.baseURL
          default:
              return URL(string: AppRootApi + "/api/appHtLoginLog/")!
          }
      }
      
      var path: String {
          switch self {
          case . childApi(child: let child):
              return child.path
          case .addLoginLog(type: _):
              return "addLoginLog"
          }
      }
      
      var method: Moya.Method {
          switch self {
          case . childApi(child: let child):
              return child.method
          default:
              return .post
          }
      }
      
      var sampleData: Data {
          switch self {
          case . childApi(child: let child):
              return child.sampleData
          default:
              return "{sampleDataKey:sampleDataValue}".data(using: String.Encoding.utf8)!
          }
      }
      
      var task: Task {
          var params:[String:Any] = [:]
          switch self {
          case . childApi(child: let child):
              return child.task
          case .addLoginLog(type: let type):
              params["type"] = type
              return .requestCompositeParameters(bodyParameters: [:], bodyEncoding: URLEncoding.httpBody, urlParameters: params)
          }
      }
      
      var headers: [String : String]? {
          switch self {
          case . childApi(child: let child):
              return child.headers
          default:
              return NetWorkManager.getHeaders(true)
          }
      }
  }

  
  

  當(dāng)模塊中接口較多時(shí)，或者部分接口需要統(tǒng)一特殊處理時(shí)，可以將部分接口抽出來(lái)，使用子模塊

  ///子模塊
  enum ChildAPI {
      case refreshInfo(name:String)
  }
  
  extension ChildAPI:TargetType {
      var baseURL: URL {
          return URL(string: AppRootApi + "/api/appHtLoginLog/")!
      }
      
      var path: String {
          switch self {
          case .refreshInfo(name: _):
              return "refreshInfo"
          }
      }
      
      var method: Moya.Method {
          switch self {
          default:
              return .post
          }
      }
      
      var sampleData: Data {
          return "{sampleDataKey:sampleDataValue}".data(using: String.Encoding.utf8)!
      }
      
      var task: Task {
          var params:[String:Any] = [:]
          switch self {
          case .refreshInfo(name: let name):
              params["name"] = name
              return .requestParameters(parameters: params, encoding: JSONEncoding.default)
          }
      }
      
      var headers: [String : String]? {
          switch self {
          default:
              return NetWorkManager.getHeaders(false)
          }
      }
  }

  
  

   

• 使用接口就這樣

      func test() {
          LoginLogManager.hzj_Request(.addLoginLog(type: 1)) { [weak self](responseModel) in
              guard let strongSelf = self else { return }
              if responseModel.code == 200 {
                  print("成功")
              }else{
                  print("失敗")
              }
          }
      }
  
      func test2() {
          LoginLogManager.hzj_Request(.childApi(.refreshInfo(name: "test"))) { [weak self](responseModel) in
              guard let strongSelf = self else { return }
              if responseModel.code == 200 {
                  print("成功")
              }else{
                  print("失敗")
              }
          }
      }
