本文介绍了Java-方法encodeBase64的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个字符串String x = "Sample text";，我想打印它的base64加密.正如无数示例提到的那样，我使用:
I have a String String x = "Sample text"; and I want to print the base64 encryption of it. As numerous examples mention, I use:
byte[] encodedBytes = Base64.encodeBase64(x.getBytes());
System.out.println("encodedBytes " + new String(encodedBytes));
但这给了我The method encodeBase64(byte[]) is undefined for the type Base64 ...那是为什么?
But this gives me The method encodeBase64(byte[]) is undefined for the type Base64... Why is that?
推荐答案
encode方法在Base64.Encoder类中，您可以通过运行Base64.getEncoder()来获取.
The encode method is in the Base64.Encoder class that you can get by running Base64.getEncoder().
byte[] encodedBytes = Base64.getEncoder().encode(x.getBytes());
类似地，要解码:
String originalString = new String(Base64.getDecoder().decode(encodedBytes));
签出 Base64 javadocs 了解更多信息.
