如何将文件转换为 Base64?

How to convert a file to Base64?(如何将文件转换为 Base64?)

问题描述

此处报告包含路径(sdcard 中的路径名，字符串格式)

Here the report contain the path(pathname in sdcard in string format)

File dir = Environment.getExternalStorageDirectory();
File yourFile = new File(dir, report);
String encodeFileToBase64Binary = encodeFileToBase64Binary(yourFile);

private static String encodeFileToBase64Binary(File fileName) throws IOException {
    byte[] bytes = loadFile(fileName);
    byte[] encoded = Base64.encodeBase64(bytes);

    String encodedString = new String(encoded);
    return encodedString;
}

在 byte[] 编码行中出现此错误.对于 Base64 类型，未定义方法 encodeBase64(byte[])

in the byte[] encoded line getting this error. The method encodeBase64(byte[]) is undefined for the type Base64

推荐答案

String value = Base64.encodeToString(bytes, Base64.DEFAULT);

但是您可以直接将其转换为 String .希望这对您有用.

But you can directly convert it in to String .Hope this will work for you.
