I am getting an error when I am trying to request using Alamofire. The error says that there is an 'extra argument in call'.
class SwiftStockKit {
class func fetchStocksFromSearchTerm(term: String, completion:#escaping (_ stockInfoArray: [StockSearchResult]) -> ()) {
DispatchQueue.global(priority: DispatchQueue.GlobalQueuePriority.default).async {
let searchURL = "http://autoc.finance.yahoo.com/autoc"
Alamofire.request(.GET, searchURL, parameters: ["query": term, "region": 2, "lang": "en"]).responseJSON { response in
if let resultJSON = response.result.value as? [String : AnyObject] {
if let jsonArray = (resultJSON["ResultSet"] as! [String : AnyObject])["Result"] as? [[String : String]] {
var stockInfoArray = [StockSearchResult]()
for dictionary in jsonArray {
stockInfoArray.append(StockSearchResult(symbol: dictionary["symbol"], name: dictionary["name"], exchange: dictionary["exchDisp"], assetType: dictionary["typeDisp"]))
}
dispatch_async(dispatch_get_main_queue()) {
completion(stockInfoArray: stockInfoArray)
}
}
}
}
}
}
The line that is giving me an error is:
Alamofire.request(.GET, searchURL, parameters: ["query": term, "region": 2, "lang": "en"]).responseJSON { response in
if anyone could fix this I would be really grateful, thanks
Try change your request to something like this:
Alamofire.request(searchURL, method: .get, parameters: ["query": term, "region": 2, "lang": "en"], encoding: JSONEncoding.default, headers: nil)

I am very new with Swift and Alamofire, what I want to accomplish is to send a data structure, like this:
{
"name" : "Test name",
"intention" : "Purpose of practice test",
"id_frequency" : "1",
"member": [
{
"id_member" : "1",
"email" : "member1#gmail.com",
"id_member_type" : 1
},
{
"id_member" : "4",
"email" : "member2#gmail.com",
"id_member_type" : 3
},
{
"id_member" : "7",
"email" : "member3#gmail.com",
"id_member_type" : 3
},
{
"id_member" : "5",
"email" : "member4#gmail.com",
"id_member_type" : 3
},
{
"id_member" : "6",
"email" : "member5#gmail.com",
"id_member_type" : 3
}
]
}
The way I am proceeding to structure the desired json, is as follows:
var membersArray = [AnyObject]()
for i in 0..<members.count {
let json: [String: Any] = [
"id_member": members[i].idMember!,
"email": members[i].email!,
"id_member_type": "\(Int(members[i].idMemberType)!)",
]
membersArray.append(json as AnyObject)
}
let jsonMembers = JSON(membersArray)
let jsonObject: [String: Any] = [
"member" : jsonMembers,
"name": name!,
"intention": intention!,
"id_frequency": frequency!
]
let jsonUpdate = JSON(jsonObject)
With this structured json, lines above (jsonUpdate). I proceed to execute the webService.
WevServices.createRequest(requestInfo: jsonUpdate) { (result) in
print(result)
}
My webservice method, looks like this:
static func createRequest(requestInfo: JSON, completion: #escaping (_ result: String) -> Void){
let url = URL(string: "http://ws.someURL.com/CreateRequest")
let parameters: [String : Any] = ["name" : "\(requestInfo["name"])", "intention" : "\(requestInfo["intention"])", "id_frequency" : "\(requestInfo["id_frequency"])", "member": requestInfo["member"]]
Alamofire.request(url!, method: .post, parameters: parameters, encoding: URLEncoding.httpBody).responseString { response in
print(response)
}
}
I'm get an error from the server that the send data would not be correct.
Note: My application use Lumen as backend.
The best way for doing what you need is :
func JSONToString(json: [String : String]) -> String?{
do {
let mdata = try JSONSerialization.data(withJSONObject: json, options: JSONSerialization.WritingOptions.prettyPrinted) // json to the data
let convertedString = String(data: mdata, encoding: String.Encoding.utf8) // the data will be converted to the string
print("the converted json to string is : \(convertedString!)") // <-- here is ur string
return convertedString!
} catch let myJSONError {
print(myJSONError)
}
return ""
}
and for alamofire request do this :
static func createRequest(requestInfo: [String :String], completion: #escaping (_ result: String) -> Void){
let url = URL(string: "http://ws.someURL.com/CreateRequest")
let parameters: [String : Any] = ["request" : JSONToString(json : requestInfo)!]
Alamofire.request(url!, method: .post, parameters: parameters, encoding: URLEncoding.httpBody).responseString { response in
print(response)
}
I am creating an Event app where in the user should tap Check In Button to register for the event. registered_flag : false will be true and registered_type: 0 will be 1 once the user tapped the button. But as I build and run the app, error appeared that says
responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error
Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character
0." UserInfo={NSDebugDescription=Invalid value around character 0.})).
I am not really confident regarding the content of my codes in my APIService. Hope someone will help me to correct my codes so I could build and run my app successfully. Thank you so much.

postman response
I have an admin panel which admin can insert question and gives 3 options of answers to users to choose. The admin is able to insert questions according to different chapters...its like a quiz game..The correct answer is then given an int value so in my collection of 3 buttons, I am able to know which is the correct button user has chosen. But now my problem is, in my Postman:
in my swift code
func getaQuestionaByaChapter(chapterName: String,question: String, answer1: String, answer2 : String, answer3: String, answer: Int, completion: #escaping (JSON?, Error?) -> Void) {
let parameters: [String : Any] = [
"secret_key" : "b3370e1590a2cf2b430e8cf8a8b361bd",
"_action" : "GETQUESTIONBYCHAPTER",
"GETQUESTIONBYCHAPTER" : chapterName,
"question" : question,
"option1" : answer1,
"option2" : answer2,
"option3" : answer3,
"answer" : answer
]
is this a declaration correct?
as for my storyboard:
and after this, i would be doing
button1.setTitle = answer1
questionlabel.text = question
in my swift file for the part where i link my API
import SwiftyJSON
import Alamofire
public class EduappRestClient {
enum ContentType: String {
case json = "application/json"
case jpeg = "image/jpeg"
case formEncoded = "application/x-www-form-urlencoded"
case none = "" //Content type will be empty
}
private static let url: URL = URL(string: "http://192.168.0.127:81/project/Online_Question/API/actiona")! //NSURL depreciated now using URL)
//singleton
static let sharedClient: EduappRestClient = EduappRestClient()
class func request(with url: URL,
method: HTTPMethod = .get,
parameters: Parameters? = nil,
contentType: ContentType = .json,
encoding: ParameterEncoding = JSONEncoding.default,
additionalHeaders: [String: String] = [:],
completion: #escaping(JSON?, Error?) -> Void
) {
//MARK: Configure Headers
var headers: [String: String] = [:]
//if contenttype is specified as none type, leave content-type header field empty
if contentType != .none {
headers["Content-Type"] = contentType.rawValue
}
for (key, value) in additionalHeaders {
headers[key] = value
}
Alamofire.request(url, method: method, parameters: parameters, encoding: encoding, headers: headers).responseJSON(completionHandler: { (response) in
guard response.result.error == nil, let value = response.result.value else {
completion(nil, response.result.error)
return
}
let jsonData = JSON(value)
completion(jsonData, nil)
})
}
//MARK: - Getting questions by chapters
func getaQuestionaByaChapter(chapterName: String,question: String, answer1: String, answer2 : String, answer3: String, answer: Int, completion: #escaping (JSON?, Error?) -> Void) {

"secret_key" : "b3370e1590a2cf2b430e8cf8a8b361bd",

"GETQUESTIONBYCHAPTER" : chapterName,
"question" : question,
"option1" : answer1,
"option2" : answer2,
"option3" : answer3,
"answer" : answer
]
let URLString = EduappRestClient.url
EduappRestClient.request(with: URLString, method: .post, parameters: parameters) { (json, error) in
guard error == nil, let json = json else {
completion(nil, error)
return
}
let result: JSON = json[1]
//result will print
//"question": [
// {
//"question": "10+10",
//"chapter_name": "Chapter 2",
//"option1": "10",
//"option2": "20",
//"option3": "30",
//"answer": "20"
//}
//]
completion(result, nil)
}
}}
it will show my data accordingly??
After API response, you have to use.
class QuestionModel: Codable {
let questions: [Details]
}
class Details: Codable {
let question: String?
let chapter_name: String?
let option1: Int?
let option2: Int?
let option3: Int?
}
And after this, you have to parse the response in the model data:
func getaQuestionaByaChapter(chapterName: String, completion: #escaping (QuestionModel?, Error?) -> Void) {
let parameters: [String : Any] = [
"secret_key" : "b3370e1590a2cf2b430e8cf8a8b361bd",
"_action" : "GETQUESTIONBYCHAPTER",
"GETQUESTIONBYCHAPTER" : chapterName
]
let URLString = EduappRestClient.url
EduappRestClient.request(with: URLString, method: .post, parameters: parameters) { (json, error) in
guard error == nil, let json = json else {
completion(nil, error)
return
}
do {
let jsonData = try JSONSerialization.data(withJSONObject: json, options: JSONSerialization.WritingOptions.prettyPrinted)
let result = try JSONDecoder().decode(QuestionModel.self, from: jsonData)
completion(result, nil)
} catch let message {
print("JSON serialization error:" + "\(message)")
}
}
}}
Then in QuizViewController: You have to set the data:
EduappRestClient.sharedClient.getaQuestionaByaChapter(chapterName: "Chapter 2", completion: { (response, error) in
//json is the result from rest client
let firstQuestion = response?.questions.first
self.questionsLabel.text = firstQuestion?.question
self.answerButtons.setTitle("\(firstQuestion?.option1)", for: UIControlState.normal)
self.answerButtons.setTitle("\(firstQuestion?.option2)", for: UIControlState.normal)
self.answerButtons.setTitle("\(firstQuestion?.option3)", for: UIControlState.normal)
})
Using Alamofire for .post api, api giving data in postman but not in my code. Posting below the code, please guide what wrong i am doing here:
// API calling method:
parameters = [
"Address" : "" as AnyObject,
"Name" : "" as AnyObject,
"ServiceID" : "" as AnyObject,
"Rating" : "" as AnyObject,
"Price" : "" as AnyObject
]
let headers: Dictionary = [
"" : ""
]
print(parameters)
ApiServices.requestPOSTURL(strURL, params: parameters, headers: headers, success:{
(JSONResponse) -> Void in
CommonMethodsClass.hideHUD(targetView: self.view)
print(JSONResponse["message"])
let strMsg = JSONResponse["message"].stringValue
if (JSONResponse["status"].intValue == 1)
{
}
else
{
CommonMethodsClass.showAlertMessage(vc: self, titleStr: "Error!", messageStr: strMsg)
}
}) {
(error) -> Void in
print(error)
CommonMethodsClass.hideHUD(targetView: self.view)
}
// Api request method:
class func requestPOSTURL(_ strURL : String, params : [String : AnyObject]?, headers : [String : String]?, success:#escaping (JSON) -> Void, failure:#escaping (Error) -> Void){
Alamofire.request(strURL, method: .post, parameters: params, encoding: JSONEncoding.default).responseJSON { (responseObject) -> Void in
print(responseObject)
if responseObject.result.isSuccess {
let resJson = JSON(responseObject.result.value as Any)
success(resJson)
}
if responseObject.result.isFailure {
let error : Error = responseObject.result.error!
failure(error)
}
}
}
Error: FAILURE:
responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error
Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character

Update: Response to parse, may also needs to be changed.

Replace responseJSON with responseString.
You need to convert the string for values. Can you update the string in your question?
You can use this function to convert response string into JSON:
func convertToDictionary(text: String) -> [String: Any]? {
if let data = text.data(using: .utf8) {
do {
return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
} catch {
print(error.localizedDescription)
}
}
return nil
}
String: let str = "{\"name\":\"James\"}"
USAGE: let dict = convertToDictionary(text: str)
Try responseString instead of responseJSON and it will work
Alamofire.request("URL").responseString { response in
print(response)
if let json = response.result.value {
print("JSON: \(json)")
}
}
Change responseJSON to responseString and it will work :)
Alamofire.request("URL").responseString { response in
print(response)
if let json = response.result.value {
print("JSON: \(json)")
}
}
I want to post data as parameter like this:
{
"data":
[
{
"nik" : "lalaal"
}
]
}
How do I write to these parameters in Swift 3 using Alamofire?
i tried :
let parameter: Parameters = [
"data":[[
"nik" : self.nik,
"check_type" : "IN",
"tanggal" : "01-08-2017 18:22:00",
"long" : String(locationList[projectChoosen].long!),
"lat" : String(locationList[projectChoosen].lat!),
"id_loc" : locationList[projectChoosen].id_project,
"id_project" : nil,
"nama_project" : locationList[projectChoosen].nama_project,
"barcode" : "",
"foto": "",
"mime_type" : "image/jpeg"
]]
]
You can use below code.
let dicRequest: NSDictionary = ["userid" : "test", "password" : "test123"]
let postParams:NSDictionary = [
"data": dicRequest
]
let requestURL: String = String(format: "%#/Login", serverURL)
Alamofire.request(requestURL, method: .post, parameters: postParams as? [String : AnyObject], encoding: JSONEncoding.default, headers: [:])
.responseJSON { response in switch response.result {
case .success(let JSON):
print("response :-----> ",response)
case .failure(let error):
print("Request failed with error: \(error)")
}
}
You can create a Dictionary object first in this formate
{
"data":
[
{
"nik" : "lalaal"
}
]
}
After that you can convert this using NSJSONSerlisation to json string
And than post using Almofire.
let array: [[String: String]] = [["nik": "lalaal"]]
let data = try JSONSerialization.data(withJSONObject: array, options: JSONSerialization.WritingOptions.prettyPrinted)
let string = String(data: data, encoding: String.Encoding.utf8)
let postParam: [String: String] = ["data": string]
let _ = Alamofire.request(apiType.url!, method: apiType.type!,parameters: postParam, encoding: JSONEncoding.prettyPrinted, headers: nil).validate(statusCode: 200..<500).responseJSON { (response) in
}
Here is a sample request using Alamofire and posting a dictionary as parameters:
let dataArray: [[String: String]] = [["nik": "lalaal"]]
let param: [String: [Any]] = ["data": dataArray]
Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: nil).responseJSON { response in }
I use :
let dataIn: [String: String] = ["param1": "value1"]
let paramGo: [String: [String: String]] = ["data_title": dataIn]
Alamofire.request(url, method: .post, parameters: paramGo, encoding: JSONEncoding.default, headers: nil).responseJSON { response in }
