问题描述
So I have this c# application that needs to ping my web server thats running linux/php stack.
I am having problems with the c# way of base 64 encoding bytes.
my c# code is like:
byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("the string");
String enc = Convert.ToBase64String(encbuff);
and php side:
$data = $_REQUEST['in'];
$raw = base64_decode($data);
with larger strings 100+ chars it fails. I think this is due to c# adding '+'s in the encoding but not sure. any clues
解决方案
You should probably URL Encode your Base64 string on the C# side before you send it.
And URL Decode it on the php side prior to base64 decoding it.
C# side
byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("the string");
string enc = Convert.ToBase64String(encbuff);
string urlenc = Server.UrlEncode(enc);
and php side:
$data = $_REQUEST['in'];
$decdata = urldecode($data);
$raw = base64_decode($decdata);
