Java Base64 和 File 之间互转

Base64 转 File

public File base64ToFile(String base64, String filePath) {        File file = new File(filePath);        byte[] buffer;        try {            BASE64Decoder base64Decoder = new BASE64Decoder();            buffer = base64Decoder.decodeBuffer(base64);            FileOutputStream out = new FileOutputStream(filePath);            out.write(buffer);            out.close();        } catch (Exception e) {            Log.e("TAG", "异常信息:" + e.getMessage());        }        return file;    }

File 转 Base64

public String fileToBase64(String filePath) {File file = new File(filePath);FileInputStream inputFile;try {inputFile = new FileInputStream(file);byte[] buffer = new byte[inputFile.available()];inputFile.read(buffer);inputFile.close();BASE64Encoder base64Encoder = new BASE64Encoder();Log.i("encodeFileToBase64", "encode = " + base64Encoder.encode(buffer));return base64Encoder.encode(buffer);} catch (Exception e) {Log.e("TAG", "异常信息:" + e.getMessage());}return "";}
