Base64编码的InputStream为String [英] Base64 InputStream to String

问题描述

我一直在试图让一个输入流中读取一个文件，ISA纯文本，并镶嵌着一些图像和其他文件的base64 ，并在String再写一遍。但是，保持编码，我的意思是，我想在字符串是这样的：

I have been trying to get an input stream reading a file, which isa plain text and has embeded some images and another files in base64 and write it again in a String. But keeping the encoding, I mean, I want to have in the String something like:

/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDAAoHBwgHBgoICAgLCgoLDhgQDg0NDh0VFhEYIx8lJCIf
IiEmKzcvJik0KSEiMEExNDk7Pj4+JS5ESUM8SDc9Pjv/2wBDAQoLCw4NDhwQEBw7KCIoOzs7Ozs7

我一直在试图与类 Base64InputStream 多由包为 org.apache.commons。codeC 但我不能fiugure出来。任何形式的帮助将是非常美联社preciated。在此先感谢！

I have been trying with the classes Base64InputStream and more from packages as org.apache.commons.codec but I just can not fiugure it out. Any kind of help would be really appreciated. Thanks in advance!

修改

使用阅读器code海贼王：

Piece of code using a reader:

 BufferedReader br= new BufferedReader(new InputStreamReader(bodyPart.getInputStream()));
                        StringBuilder sb = new StringBuilder();
                        String line;
                        while ((line = br.readLine()) != null) {
                            sb.append(line);
                        }
                        br.close();

获取结果是这样的： .DIC; YUC（（;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;;;;;;;;;;;;;;;;;;;;;;雅@@雅

推荐答案

我找到了解决方案，通过这个帖子的启发<一个href=\"http://stackoverflow.com/questions/2764504/getting-base64-content-string-of-an-image-from-a-mimepart-in-java\">getting从Java中的mimepart图像的base64内容字符串

I found the solution, inspired by this post getting base64 content string of an image from a mimepart in Java

我觉得这是一种愚蠢的去code和EN code再次的base64 code，但我发现来管理这一问题的唯一途径。如果有人能给出一个更好的解决方案，这将是也确实AP preciated。

I think it is kind of stupid decode and encode again the base64 code, but it is the only way I found to manage this issue. If someone could give a better solution, it would be also really appreciated.
