Download zip fil and unzip it using Alamofire in Swift

问题

I have a zip file of assets in AWS S3 bucket. I want to download that zip file using Alamofire and unzip and save it on my device. I am using Swift. Please help.

  1. func downloadFile(url: URL, completionHandler: @escaping (NSDictionary?, Error?) -> Void) {
  2.     let destinationPath: DownloadRequest.Destination = { _, _ in
  3.         let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
  4.         let fileURL = documentsURL.appendingPathComponent("Assets.zip")
  5.         return (fileURL, [.removePreviousFile, .createIntermediateDirectories])
  6.     }
  7.     
  8.     AF.download(url, to: destinationPath).responseData { response in
  9.         print(response)
  10.         switch response.result {
  11.         case .success(_):
  12.             print("Successfully Downloaded")
  13.         case .failure(_):
  14.             print("Download failed")
  15.         }
  16.     }
  17. }

得分: 1

首先需要安装 pod
https://cocoapods.org/pods/Zip

然后

  1. import Zip

下载函数调用

  1. self.downloadPdf(pdfReport: webLink, savePathURL: finalDestinationUrl) { (pdfFilePath, status) in
  3.     if FileManager.default.fileExists(atPath: pdfFilePath){
  5.         try? Zip.unzipFile(pathUrl, destination: finalUrl ?? validUrl, overwrite: true, password: nil, progress: { (progress) in
  6.             print(progress)
  7.         })
  9.     }
  10. }

下载函数定义

  1. func downloadPdf(pdfReport: String, savePathURL: URL, completionHandler:@escaping(String, Bool)->()){
  3.     let downloadUrl: String =  pdfReport
  4.     let destinationPath: DownloadRequest.Destination = { _, _ in
  5.         return (savePathURL, [.removePreviousFile, .createIntermediateDirectories])
  6.     }
  7.     debugPrint("downloadUrl=>",downloadUrl)
  8.     AF.download(downloadUrl, to: destinationPath)
  9.         .downloadProgress { progress in
  11.         }
  12.         .responseData { response in
  13.             print("response: \(response)")
  14.             switch response.result{
  15.             case .success:
  16.                 if response.error == nil, let filePath = response.fileURL?.path {
  17.                     completionHandler(filePath, true)
  18.                 }
  19.                 break
  20.             case .failure:
  21.                 completionHandler("", false)
  22.                 break
  23.             }
  25.         }
  26. }

First of all need to install pod
https://cocoapods.org/pods/Zip

Then

  1. import Zip

Download function call

  1.     self.downloadPdf(pdfReport: webLink, savePathURL: finalDestinationUrl) { (pdfFilePath, status) in
  2.         
  3.         if FileManager.default.fileExists(atPath: pdfFilePath){
  4.             
  5.             
  6.             try? Zip.unzipFile(pathUrl, destination: finalUrl ?? validUrl, overwrite: true, password: nil, progress: { (progress) -> () in
  7.                 print(progress)
  8.                 
  9.                 
  10.             })
  11.             
  12.         }
  13.     }

Download function definition

  1. func downloadPdf(pdfReport: String, savePathURL: URL, completionHandler:@escaping(String, Bool)->()){
  2.     
  3.     let downloadUrl: String =  pdfReport
  4.     let destinationPath: DownloadRequest.Destination = { _, _ in
  5.         return (savePathURL, [.removePreviousFile, .createIntermediateDirectories])
  6.     }
  7.     debugPrint("downloadUrl=>",downloadUrl)
  8.     AF.download(downloadUrl, to: destinationPath)
  9.         .downloadProgress { progress in
  10.             
  11.         }
  12.         .responseData { response in
  13.             print("response: \(response)")
  14.             switch response.result{
  15.             case .success:
  16.                 if response.error == nil, let filePath = response.fileURL?.path {
  17.                     completionHandler(filePath, true)
  18.                 }
  19.                 break
  20.             case .failure:
  21.                 completionHandler("", false)
  22.                 break
  23.             }
  24.             
  25.         }
  26. }
