Solve the Base64.encodeBase64String newline carriage return problem

The signature error is always reported during interface Docking. The problem with Base64 is traced step by step and recorded as follows:

According to RFC 822, a carriage return line is also required for every 76 characters.

The solution is as follows: replace all the line breaks and carriage returns.

Private static String base64 (String str, String charset) throws UnsupportedEncodingException {
String encoded = Base64.encodeBase64String (str. getBytes (charset ));
Encoded = encoded. replaceAll ("[\ s * \ t \ n \ r]", "");
Return encoded;
}

Subtotal: This problem does not exist in the php environment

/**

* @ Param appkey Appkey
* @ Return DataSign signature

Function encrypt ($ data, $ appkey ){
Return urlencode (base64_encode (md5 ($ data. $ appkey )));
}
