Java.Util 組件: Mono.Android.dll Encoder傳回使用 <href=“#basic”>Basic</a> type base64 編碼配置進行編碼的 。 [Android.Runtime.Register("getEncoder", "()Ljava/util/Base64$Encoder;", "", ApiSince=26)] public static Java.Util.Base64.Encoder? GetEncoder(); ...
import java.util.Base64; 复制代码 对字符串进行编码: String originalString = "Hello World!"; String encodedString = Base64.getEncoder().encodeToString(originalString.getBytes()); 复制代码 对编码后的字符串进行解码: String decodedString = new String(Base64.getDecoder().decode(encodedString)); ...
importjava.util.Base64;publicclassBase64EncoderExample{publicstaticvoidmain(String[]args){// 待编码的字符串Stringstr="Hello, World!";// 获取编码器Base64.Encoderencoder=Base64.getEncoder();// 将字符串编码为Base64格式StringencodedStr=encoder.encodeToString(str.getBytes());// 输出编码后的字符串Sy...
import java.nio.charset.StandardCharsets; import java.util.Base64; public class Base64Encoder { public static void main(String[] args) { String input = "Hello, World!"; String encoded = encodeBase64(input); System.out.println("Base64 encoded string: " + encoded); } public static String...
java.util.Base64 基本使用 @Test public void de() throws Exception { final Base64.Decoder decoder = Base64.getDecoder(); final Base64.Encoder encoder = Base64.getEncoder(); final String text = "字串文字"; final byte[] textByte = text.getBytes("UTF-8");...
Base64工具类提供了一套静态方法获取下面三种BASE64编解码器:基本、URL、MIME。 1、基本: 1@Test2publicvoidtestBase64()throwsUnsupportedEncodingException {3String srcStr = "-`测试Base64_$(#)*^》/,。;\"'";4//编码 A-Za-z0-9+/5String base64encodedString = Base64.getEncoder().encodeToString(...
JDK1.6中添加了另一个Base64的实现,javax.xml.bind.DatatypeConverter两个静态方法parseBase64Binary 和 printBase64Binary,隐藏在javax.xml.bind包下面。 在Java 8在java.util包下面实现了Base64编解码API,而且性能不俗,API也简单易懂。该Base64有3个Encoder,分别是“标准Encoder”、“urlEncoder”、“mimeEncoder...
首先,我们可以通过Base64类的getEncoder()方法获取一个 Base64 编码器对象: importjava.util.Base64;Base64.Encoderencoder=Base64.getEncoder(); 1. 2. 3. 然后,可以使用编码器对象的encodeToString()方法将图片转换成 Base64 字符串: Stringbase64Image=encoder.encodeToString(imageBytes); ...
