I have tried with parameters, but doesnt wotk
Alamofire.request(urlservice, method: .post, parameters: ["data": parameters], encoding: JSONEncoding.default, headers: nil).responseJSON { response in
Any suggestions?
UPDATE
Here is my code
var arrayProducts = [[String: String]]()
let product: [String: String] = ["qty": self.txtQty.text!, "precio": self.productPrice, "product_id": self.productId]
arrayProducts.append(product)
let parameters = [
"products": arrayProducts,
"address": self.userInfo["userAddress"]!,
"latitude": "6.157738",
"longitude": "-75.6144665",
"id": 1,
"name": self.userInfo["userName"]!,
"cellphone": self.userInfo["userPhone"]!,
"emei": "23456resdfty"
] as [String : Any]
Alamofire.request(urlservice, method: .post, parameters: ["data": parameters], encoding: JSONEncoding.default, headers: nil).responseJSON { response in

Answer 1

when you have an Any Data as paremeter, you should sent the URLRequest to Alamofire, it supports Any as body
var request = URLRequest(url: URL(string: url)!)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = try! JSONSerialization.data(withJSONObject: parameters, options: [])
Alamofire.request(request)
.responseString { (response) in
// to do anything
}

Here is an example 4 you, the CURL statement an example of what it is doing.
Note token referenced here is a shared secret, obviously not stuff to post to SO :) bags of print statements in here so that you can see what going on/wrong :)
func files_download(sourcePath: String) {
// curl -X POST https://content.dropboxapi.com/2/files/download
// --header "Authorization: Bearer ab-XXX"
// --header "Dropbox-API-Arg: {\"path\": \"/acme101/acme1/acme.png\"}"
var headers:HTTPHeaders!
let subPart: Dictionary = ["path":sourcePath]
do {
let data = try JSONSerialization.data(withJSONObject: subPart, options: [])
let dataString = String(data: data, encoding: .utf8)
headers = ["Authorization": "Bearer " + token, "Dropbox-API-Arg": dataString!]
} catch {
print("Oh fudge")
}
Alamofire.request("https://content.dropboxapi.com/2/files/download", method: .post, encoding: JSONEncoding.init(options: []), headers: headers).responseData(completionHandler: {feedback in
guard feedback.result.value != nil else {
print("Error: did not receive data", //rint("request \(request) feedback \(feedback)"))
return
}
guard feedback.result.error == nil else {
print("error calling POST on list_folder")
print(feedback.result.error)
return
}
if let JSON = feedback.result.value {
print("JSON: \(JSON)")
let dataString = String(data: JSON, encoding: .utf8)
print("JSON: \(JSON) \(String(describing: dataString))")
}
if let IMAGE = feedback.result.value {
print("downloaded \(sourcePath) \(sharedDataAccess.currentSN)")
sharedDataAccess.fnData(index2seek: sharedDataAccess.currentSN, fnData: feedback.result.value! as Data)
NotificationCenter.default.post(name: Notification.Name("previewPane"), object: nil, userInfo: nil)
}
})
}
