Java:使用带引号的可打印字符串编码 [英] Java: Encode String in quoted-printable

问题描述

我正在寻找一种quoted-printable在Java中编码字符串的方法，就像php的本机 quoted_printable_encode() 函数.

I am looking for a way to quoted-printable encode a string in Java just like php's native quoted_printable_encode() function.

我尝试使用JavaMails的MimeUtility库.但是我无法获得

I have tried to use JavaMails's MimeUtility library. But I cannot get the encode(java.io.OutputStream os, java.lang.String encoding) method to work since it is taking an OutputStream as input instead of a String (I used the function getBytes() to convert the String) and outputs something that I cannot get back to a String (I'm a Java noob :)

有人可以给我提示如何编写将字符串转换为OutputStream并在编码后将结果输出为String的包装器吗?

Can anyone give me tips on how to write a wrapper that converts a String into an OutputStream and outputs the result as a String after encoding it?

推荐答案

要使用此MimeUtility方法，您必须创建一个ByteArrayOutputStream，该ByteArrayOutputStream会累积写入该字节的字节，然后可以对其进行恢复.例如，对字符串original进行编码:

To use this MimeUtility method you have to create a ByteArrayOutputStream which will accumulate the bytes written to it, which you can then recover. For example, to encode the string original:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
OutputStream encodedOut = MimeUtility.encode(baos, "quoted-printable");
encodedOut.write(original.getBytes());
String encoded = baos.toString();
