Question

I am trying to send array as parameter to server but server is not receiving. Server have to receive two arrays that I am sending. But in server they are not appear ?? I dont know is it my mistake or mistake in the server ??
My array name is testAns and testQuest and I have to send it to parameters: answer and quest.
my Code:
let userID = UserDefaults.standard.string(forKey: "userID")
let artID = UserDefaults.standard.string(forKey: "index")
let myUrl = URL(string: "http://www.someurls.kz/modules/CheckTestF.php");
var request = URLRequest(url:myUrl!)
request.httpMethod = "POST"
var testAns = [Int]()
var testQuest = [Int]()
testAns = [131,123,23]
testQuest = [123,233,232]
let postString = "uID=97B436E41&idUser=\(userID!)&art_id=\(artID!)&answer=\(testAns)&quest=\(testQuest)"
print(postString)
print(testAns,testQuest)
request.httpBody = postString.data(using: String.Encoding.utf8);
let task = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
if error != nil
{
print("error=\(String(describing: error))")
return
}
do {
_ = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
}
catch {
print(error)
}
}
task.resume()
}

Answer 1

i don't know how to encode that array on your server side.
but temporary you can try this way and check your database.
let postString = "uID=97B436E41&idUser=\(userID!)&art_id=\(artID!)&answer[0]=131&answer[1]=123&quest[0]=123&quest[1]=233"

You can use the Alamofire that is very popular at this time that is advanced version of AFNetworking
Also, I am sharing the method that will help you to hit API, You have to pass only the dictionary object in this method and this will give you the response in two blocks and you can use them as per requirements.
1: unReachable()
2: handler(responseDict)
//MARK: *********** HIT POST SERVICE IN JSON FORM***********
func hitPostServiceJsonForm(_ params:Dictionary<String,Any>,unReachable:(() -> Void),handler:#escaping ((Dictionary<String,Any>?) -> Void)) {
if networkReachable() == false {
unReachable()
}
let BASE_URL = "http://mydoamain"
var request = URLRequest(url: URL(string: BASE_URL)!)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = try! JSONSerialization.data(withJSONObject: params, options: .prettyPrinted)
print(BASE_URL)
Alamofire.request(request).responseJSON { response in
//print("Request: \(String(describing: response.request))") // original url request
//print("Response: \(String(describing: response.response))") // http url response
print("Result: \(response.result)") // response serialization result
switch response.result {
case .success:
if let jsonDict = response.result.value as? Dictionary<String,Any> {
print("Json Response: \(jsonDict)") // serialized json response
handler(jsonDict)
}
else{
handler(nil)
}
if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
print("Server Response: \(utf8Text)") // original server data as UTF8 string
}
break
case .failure(let error):
handler(nil)
print(error)
break
}
}
}
func networkReachable() -> Bool {
return (NetworkReachabilityManager()?.isReachable)!
}

convert the your array to json string then try to send it to server
func post_array(){
let userID = UserDefaults.standard.string(forKey: "userID")
let artID = UserDefaults.standard.string(forKey: "index")
let myUrl = URL(string: "http://www.someurls.kz/modules/CheckTestF.php");
var request = URLRequest(url:myUrl!)
request.httpMethod = "POST"
var testAns = [Int]()
var testQuest = [Int]()
testAns = [131,123,23]
testQuest = [123,233,232]
var tempAns : NSString = ""
do {
let arrJson = try JSONSerialization.data(withJSONObject: testAns, options: .prettyPrinted)
let string = NSString(data: arrJson, encoding: String.Encoding.utf8.rawValue)
tempAns = string! as NSString
}catch let error as NSError{
print(error)
}
var tempQuest : NSString = ""
do {
let arrJson = try JSONSerialization.data(withJSONObject: testQuest, options: .prettyPrinted)
let string = NSString(data: arrJson, encoding: String.Encoding.utf8.rawValue)
tempQuest = string! as NSString
}catch let error as NSError{
print(error)
}
let postString = "uID=97B436E41&idUser=\(userID!)&art_id=\(artID!)&answer=\(tempAns)&quest=\(tempQuest)"
print(postString)
print(testAns,testQuest)
request.httpBody = postString.data(using: String.Encoding.utf8);
let task = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
if error != nil
{
print("error=\(String(describing: error))")
return
}
do {
_ = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
}
catch {
print(error)
}
}
task.resume()
}
