POST required ampersand "&" in parameter for Swift

Question

I'm making a post with a required "&" in one of the parameters. I've tried %26 for & with NSUTF8StringEncoding, as well as, stringByAddingPercentEscapesUsingEncodqing(NSUTF8StringEncoding). Not working still.

let params = "designers=dolce%26gabbana"    
let nStr = params.stringByAddingPercentEscapesUsingEncodqing(NSUTF8StringEncoding)
let postData = nStr?.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPBody = postData

The string im posting is "Dolce & Gabbana" and the server only recognizes it with the "&".

Thanks!

You should try with CFURLCreateStringByAddingPercentEscapes cause stringByAddingPercentEscapesUsingEncodqing does not escapes all characters. By using CFURLCreateStringByAddingPercentEscapes, you choose characters to escapes.

Example:

var encodedStr = CFURLCreateStringByAddingPercentEscapes(
    nil,
    "Dolce & Gabbana",
    nil,
    "&", //you can add another special characters
    CFStringBuiltInEncodings.UTF8.rawValue
)

Thanks! how would i go about encoding it for the HTTPBody? There's no .dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true) for CFString – Tuan Anh Vu Apr 17 '15 at 23:18
try to get first String by `let str = String(encodedStr)` then convert to `NSData` . – Duyen-Hoa Apr 17 '15 at 23:47
Can it be a problem in server side while decoding parameters? – Duyen-Hoa Apr 17 '15 at 23:51
