I know how to post this type of format to json in objective-c, here is my code
NSURL *url=[NSURL URLWithString:#"http://adservicedev.azurewebsites.net/order/json/process"];
dict = #{#"Authentication":#{#"Username":#"testUser#123",#"Password":#"testPassword#123"},#"RequestType":[NSNumber numberWithInt:4]};
if([NSJSONSerialization isValidJSONObject:dict])
{
__jsonData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil];
__jsonString = [[NSString alloc]initWithData:__jsonData encoding:NSUTF8StringEncoding];
NSLog(#"Error %#", __jsonString);
}
// Be sure to properly escape your url string.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setHTTPBody: __jsonData];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%lu", (unsigned long)[__jsonData length]] forHTTPHeaderField:#"Content-Length"];
NSError *errorReturned = nil;
NSURLResponse *theResponse =[[NSURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
but am new to swift language,how to write the same in swift.Please help me out.

Well that's the way you need to implement.
Swift code
let request = NSMutableURLRequest(URL: NSURL(string: "http://localhost:8888/php/index.php")!)
request.HTTPMethod = "GET"
let postString = "" // if you want to pass some string to the url you can also do it here i.e type=user now on php side you can get the value by using $_GET['type'] or $_REQUEST['type']
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request)
{
data, response, error in
if error != nil
{
println("error=\(error)")
return
}
var jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
var FileID : NSString = jsonResult["FileID"]! as NSString
var RequestType : NSString = jsonResult["RequestType"]! as NSString
let Auth : AnyObject = jsonResult["Authentication"]!
var Username : NSString = Auth["Username"]! as NSString
var Password : NSString = Auth["Password"]! as NSString
println("Username : \(Username)")
println("Password : \(Password)")
println("RequestType : \(RequestType)")
println("FileID : \(FileID)")
println("Auth : \(Auth)")
}
task.resume()
PHP code (index.php)
<?php
$v = '{"Authentication": {"Username": "testUser#123","Password": "testPassword#123" },"FileID": "2","RequestType": 5}';
echo $v;
?>
Final Output
