Swift.Alamofire的封装

实现功能:

自动缓存,网络状态监听,无网络状态自动调用缓存数据.

统一全局manager,一次设定baseURL与header.全局使用.

优化调用方式,使网络请求更轻便,更直观.

#使用第三方库:

Alamofire: 核心功能,网络请求.

SwiftyJSON: 数据缓存时使用,方便地处理JSON数据.

/建议配合使用MBProgressHud,但因为非必须,demo中去掉了./

1.自动缓存

在网络请求成功时调用,将数据存储.

/// 进行数据缓存
    ///
    /// - Parameters:
    ///   - responseObject: 缓存数据
    ///   - request: 请求
    ///   - parameters: 参数
    public func cacheResponseObject(responseObject: AnyObject,
                                   request: URLRequest,
                                   parameters: Dictionary<String,Any>?){
        if !(responseObject is NSNull) {
            let directoryPath:String = cachePath
            ///如果没有目录,那么新建目录
            if !FileManager.default.fileExists(atPath: directoryPath, isDirectory: nil){
                do {
                    try FileManager.default.createDirectory(atPath: directoryPath,
                                                            withIntermediateDirectories: true,
                                                            attributes: nil)
                }catch let error {
                    print("create cache dir error: " + error.localizedDescription + "\n")
                    return
                }
            }
            ///将get请求下的参数拼接到url上
            let absoluterURL = self.generateGETAbsoluteURL(url: (request.url?.absoluteString)!, parameters)
            ///对url进行md5加密
            let key = absoluterURL.md5()
            ///将加密过的url作为目录拼接到默认路径
            let path = directoryPath.appending(key)
            ///将请求数据转换成data
            let dict:AnyObject = responseObject
            var data:Data? = nil
            do{
                try data = JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted)
            }catch{
            }
            ///将data存储到指定路径
            if data != nil{
                let isOk = FileManager.default.createFile(atPath: path,
                                                          contents: data,
                                                          attributes: nil)
                if isOk{
                    print("cache file ok for request: \(absoluterURL)\n")
                }else{
                    print("cache file error for request: \(absoluterURL)\n")
                }
            }
        }
    }

2.网络状态监听.

  ///监听网络状态
    public func detectNetwork(netWorkStatus: @escaping ELNetworkStatus){
        let reachability = NetworkReachabilityManager(
