我有一个编码字符串,我该如何解码它

eNpTNXdSNTJKLSrKLwLSqsaOJUWlqapGzkBOSmpxMlQQSKYlZuakpqgaGSSWlmTkF2VWJZZk5ueBpM1dALkhFLk=

gzdecode, gzinflate, zlib_decode 输出 false

on this site it stands for as it should be

这里有很多层要解码:

$result = json_decode(urldecode(zlib_decode(base64_decode($str))), true);

这产生:

Array
(
    [error] => 1
    [descr] => failed authorization
)
