将＆符号转换为UTF 8

Question

I send post request with data to my server:

var syncData = "data=Hello&World"
let urlRequest = NSMutableURLRequest(URL: NSURL(string: url)!, cachePolicy:  NSURLRequestCachePolicy.ReloadIgnoringCacheData, timeoutInterval: NSTimeInterval(60))

urlRequest.HTTPMethod = "POST"
urlRequest.HTTPBody = syncData.dataUsingEncoding(NSUTF8StringEncoding)

But problem that server can't decode &(ampersand) character. On server i get only word "Hello". And it is not the server issue. because i tried to sent this string with java and python and curl.
All works good.

I tried this: NSXMLParser problem with "&"(Ampersand) character

but it doesn't help... Any ideas ?

Answer 1

As Musa said. Solution will be:

let customAllowedSet =  NSCharacterSet(charactersInString:"=\"#%/<>?@\\^`{|}&").invertedSet
    syncData = syncData.stringByAddingPercentEncodingWithAllowedCharacters(customAllowedSet)!

    urlRequest.HTTPBody = syncData.dataUsingEncoding(NSUTF8StringEncoding)

Answer 2

try

var sync = syncData.stringByReplacingOccurrencesOfString("&", withString: " ")
urlRequest.HTTPBody = sync.dataUsingEncoding(NSUTF8StringEncoding)

place the sync variable under the syncData variable and replace your urlRequest with the one above using the new sync variable
