[移动开发]ios swift alamofire 上传图片（文件）上传进度

• 下面的代码本人亲测有效

extension SSNetworkManager {
    //MARK: 上传图片 -
    func uploadingImage(imageData:Data,complete:@escaping Completion){
        let url = baseURL + "/misc/update"

        upload(multipartFormData: { (multipartFormData) in
            
            multipartFormData.append(imageData, withName: "file",fileName: "file.jpg", mimeType: "image/jpg")
            
        }, to: url,headers: baseHeaders) { (encodingResult) in
            
            printXY("我的：\(encodingResult)", obj: self, line: #line)
            
            switch encodingResult {
            case .success(let upload, _, _):
                
                upload.uploadProgress { (progress) in
                    
                    printXY(progress, obj: self, line: #line)
                    printXY(progress.fractionCompleted, obj: self, line: #line)
                    printXY(progress.totalUnitCount, obj: self, line: #line)
                    printXY(progress.completedUnitCount, obj: self, line: #line)
                    
                }.responseJSON { response in
                    
                    if let jsonValue = response.result.value {
                        let dict:NSDictionary = jsonValue as! NSDictionary
                        printXY(dict, obj: self, line: #line)
                        let model = SSCommonModel.deserialize(from: dict)
                        complete(model!)
                    }
                }
                
            case .failure(let error):
                let errorModel = SSCommonModel(error: error.localizedDescription)
                complete(errorModel)
                
            }
            
        }
        
    }
    
}
