我想格式化 base64 编码的字符串，当我在 JSON 请求中发送以下字符串时 - 我收到 JSON 验证错误，因为此字符串的格式不正确。我找不到任何好的实用程序来将 base64 编码的字符串转换为正确的字符串。
Java/Groovy 或 Javascript 中是否有任何实用程序可以在一行中格式化。
感谢您的帮助

最佳答案
// if this is your Base64 encoded string
var str = 'VGhpcyBpcyBhbiBhd2Vzb21lIHNjcmlwdA==';
// make URL friendly:
str = str.replace(/\+/g, '-').replace(/\//g, '_').replace(/\=+$/, '');
// reverse to original encoding
str = (str + '===').slice(0, str.length + (str.length % 4));
str = str.replace(/-/g, '+').replace(/_/g, '/');
如果通过格式化您的意思是使其 URL 友好，那么代码就在上面!
如果您指的是字符串的编码和解码，
