Swift:文件在base64编码后似乎已损坏

import Foundation

// 假设你有一个文件路径
let filePath = "path/to/your/file"

// 读取文件内容
if let fileData = try? Data(contentsOf: URL(fileURLWithPath: filePath)) {
    // 将文件数据进行Base64编码
    let base64EncodedString = fileData.base64EncodedString()
    print("Base64 Encoded String: \(base64EncodedString)")
} else {
    print("Failed to read file data.")
}

import Foundation

// 假设你有一个Base64编码的字符串
let base64EncodedString = "your_base64_encoded_string_here"

// 将Base64编码的字符串解码为Data
if let decodedData = Data(base64Encoded: base64EncodedString) {
    // 将解码后的数据写入文件
    let outputFilePath = "path/to/output/file"
    if let _ = try? decodedData.write(to: URL(fileURLWithPath: outputFilePath)) {
        print("File successfully decoded and saved.")
    } else {
        print("Failed to write decoded data to file.")
    }
} else {
    print("Failed to decode Base64 string.")
}
