如何读取swift

中扩展名为 .zip 的文件的内容

我有一个由gZip制成的 .zip 文件，我需要阅读 .zip 文件的内容而不解压缩该文件

let zipData = NSData(contentsOfFile: zipfilePath) as Data?

不使用第三方库

Answer 1

您可以使用Swift本机框架，该框架允许您创建，读取和更新ZIP存档文件：ZIP Foundation。

解压缩文件基本上只是一行：

try fileManager.unzipItem(at: sourceURL, to: destinationURL)

具有某些上下文的完整示例如下所示：

let fileManager = FileManager()
let currentWorkingPath = fileManager.currentDirectoryPath
var sourceURL = URL(fileURLWithPath: currentWorkingPath)
sourceURL.appendPathComponent("archive.zip")
var destinationURL = URL(fileURLWithPath: currentWorkingPath)
destinationURL.appendPathComponent("directory")
do {
    try fileManager.createDirectory(at: destinationURL, withIntermediateDirectories: true, attributes: nil)
    try fileManager.unzipItem(at: sourceURL, to: destinationURL)
} catch {
    print("Extraction of ZIP archive failed with error:\(error)")
}

您可以检出GitHub存储库：ZIPFoundation

".gz file made from gZip"

import Gzip

let ZipFile = Bundle.main.path(forResource: "Your-File-Name", ofType: "gz")
print(ZipFile as Any)

let Data = NSData(contentsOfFile: ZipFile!) as Data?

let decompressedData: Data
if Data!.isGzipped {
    decompressedData = try! Data!.gunzipped()
} else {
    decompressedData = Data!
}

var Decompress_String = ""
if let string = String(bytes: decompressedData, encoding: .utf8) {
    Decompress_String = string
} else {
    print("not a valid UTF-8 sequence")
}

print("Decompress_String")

迅速从.zip文件中读取文件内容
