推荐答案

在我的情况下，编码字符串的末尾有换行符.使用@Arvin在此 answer 中提到的Base64.NO_WRAP作为解决方案.我的编码功能现在看起来像:

In my case, the encoded string was having a new line at the end. Using Base64.NO_WRAP as mentioned by @Arvin in this answer worked as a solution. My encoding function now looks like:

public static String encodeToBase64(String strToEncode) {
    byte[] data = null;
    try {
        data = strToEncode.getBytes("UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    return Base64.encodeToString(data, Base64.NO_WRAP);
}

如果您想要像上面的评论中提到的@BobSnyder一样安全，则仍然可以使用URL_SAFE，并只是修剪String以确保安全.

If you're aiming to be safe like what @BobSnyder mentioned in the comments above, you could still use URL_SAFE and just trim the String just to make sure.
