/**    MARK: 创建DS 请求方法列表   - GetVideosByType  根据类型获取视频列表    */  public enum DS {      case GetVideosByType(Int,Int,Int,Int) //根据类型获取视频列表  }

/**    MARK: 创建DS 请求方法列表  - GetVideosByType  根据类型获取视频列表  */  public enum DS {      case GetVideosByType(Int,Int,Int,Int) //根据类型获取视频列表  }

// MARK: - Provider setup  let DSProvider = MoyaProvider<DS>()

// MARK: - Provider setup  letDSProvider = MoyaProvider<DS>()

4.通过Moya 定义的 baseUrl 、 请求路径( path )、 Http方法、 参数和目标的示例数据的协议。

扩展DS : TargetType

extension DS: TargetType {      // 逗视API地址      public var baseURL: NSURL { return NSURL(string: "https://api.doushi.me/v1/rest/video/")! }      /// 拼接请求字符串      public var path: String {          switch self {          case .GetVideosByType(let vid, let count, let type,let userId):              return ("getVideosByType/\(vid)/\(count)/\(type)/\(userId)")          }      }      /// 请求方法      public var method: Moya.Method {          return .GET      }      /// 配置参数      public var parameters: [String: AnyObject]? {          switch self {          default:              return nil          }      }      /// 数据      public var sampleData: NSData {          switch self {          case .GetVideosByType:              return "Half measures are as bad as nothing at all.".dataUsingEncoding(NSUTF8StringEncoding)!          }      }  }

有没有发现这样写网络请求很爽，我们只维护 DSAPI 就可以了,添加请求方法，处理数据等。
