如何将base64字符串转换为文件？

import base64

def base64_to_file(base64_string, file_path):
    with open(file_path, "wb") as file:
        file.write(base64.b64decode(base64_string))

const fs = require('fs');
const path = require('path');

function base64ToFile(base64String, filePath) {
  const data = Buffer.from(base64String, 'base64');
  fs.writeFileSync(filePath, data);
}

import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Base64;

public class Base64ToFile {

    public static void base64ToFile(String base64String, String filePath) throws IOException {
        byte[] decodedBytes = Base64.getDecoder().decode(base64String);
        try (FileOutputStream fileOutputStream = new FileOutputStream(filePath)) {
            fileOutputStream.write(decodedBytes);
        }
    }
}
