Swift5 Alamofire5.0 二次封装

使用Objective-C开发的应该非常熟悉AFNetworking这个网络框架。在Swift诞生之后，AFNetworking的作者用Swift来编写一个类似AFNetworking的网络框架，那就是Alamofire！->github.

一直使用Objective-C开发，我来尝试下用Swift进行开发，首先从网络框架入手，对Alamofire进行二次封装。

目前Alamofire的最新版本是5.0.0，还没有5.0的文档 -_-!!!
直接盘它

    case notReachable     = 0//网络无连接

    case wifi             = 2//wifi网络

实例调用，使用HandyJSON进行解析

        }
        
        struct DataModel: HandyJSON {

            var video : Any?
            var list1 : Any?
            var list2 : Any?
            var list3 : Any?
        }
        self.showLoading()
        FSNetworkRequest.share.postWith(url: NetworkRequestDefine.URL_index, params: nil, success: { (json) in
            self.hideLoading()
            let model = JSONDeserializer<BaseModel>.deserializeFrom(json: json)
            debugPrint(model!)
        }) { (response) in
            debugPrint(response)
        }
    }
    
    func getData1() {
        let image = UIImage.init(named: "icon_tabbar_20")
        var fileConfig = FSFileConfig.init()
        let data = image?.jpegData(compressionQuality: 0.5)
        fileConfig.initFile(fileData: data!, name: "img", fileName: "img.jpg", mimeType: "image/jpeg")
        FSNetworkRequest.share.postImage(url: NetworkRequestDefine.URL_my_uploadimg_index, params: nil,fileConfig: fileConfig, progressBlock: { (progress) in
