Encode parameters for URL Request - swift

Question

I created a Router to generate URL Requests.
enum Router: URLRequestConvertible {
static let baseURLString = "SERVERIP"
case GetAEDInRange(String)
// match URLRequest routes to Alamofire methods
var URLRequest: NSMutableURLRequest {
var method: Alamofire.Method {
switch self {
case .GetAEDInRange:
return .GET
}
}
// The output contains the path and parameters like ("aeds", newAED)
let result: (path: String, parameters: [String: AnyObject]?) = {
switch self {
case .GetAEDInRange(let parameters):
return ("aeds", parameters)
}()
// Generate URL Request
let URL = NSURL(string: Router.baseURLString)!
// Append the path components from the result
print(result.path)
let URLRequest = NSURLRequest(URL: URL.URLByAppendingPathComponent(result.path))
// Create URLRequest inclunding the encoded parameters
let encoding = Alamofire.ParameterEncoding.JSON
let (encodedRequest, _) = encoding.encode(URLRequest, parameters: result.parameters)
encodedRequest.HTTPMethod = method.rawValue
return encodedRequest
}
}
The output I expect is: http://BASEURL/v1/aed?latitude=100&longitude=100
When I use Alamofire to make a GET request with parameters attached, it works fine:
Alamofire.request(.GET, "http://SERVER/v1/aeds", parameters: parameters).responseJSON { (response) -> Void in
print(response.result.value)
}
When I use my router instead, the output is not generated as expected:
Alamofire.request(Router.GetAEDInRange(parameters)).responseJSON { (response) -> Void in
print(response.result.value)
}
When I print the URL String, I get: `http://SERVER/v1/aeds/``
How do I need to change my router? I struggle with the parameter component somehow.

Change this line
let encoding = Alamofire.ParameterEncoding.JSON
to this:
let encoding = Alamofire.ParameterEncoding.URLEncodedInURL
To understand the difference between Parameter Encodings in Alamofire take a look here.

Swift3
'Alamofire', '~> 4.0'
let parameters: [String: Any] = [
"parameter1" : data1,
"parameter2" : data2
]
Alamofire.request("https://httpbin.org/get", parameters: parameters, encoding: URLEncoding(destination: .queryString))
