In my project I want to convert Json String from server to Array but Unable to convert, But when I hard code(Directly gave the particular json string) the json string means that will be convert. Please help me to find the issue..
Here I gave the code what i am tried.
var params = NSMutableDictionary()
params = [
"inspectionLogId": inspectionLogIdStr
]
let manager = AFHTTPSessionManager()
manager.requestSerializer = AFJSONRequestSerializer()
manager.responseSerializer = AFHTTPResponseSerializer()
manager.responseSerializer.acceptableContentTypes = NSSet(array: ["text/plain", "text/html", "application/json"]) as Set<NSObject> as Set<NSObject>! as! Set<String>?
manager.requestSerializer.setValue("", forHTTPHeaderField: "apptoken")
manager.requestSerializer.setValue(strAppToken, forHTTPHeaderField: "token")
let urlString:NSString = NSString(format: "%#%#", ApiConstantFile().baseUrlProperty,ApiConstantFile().getTemplateDataUrl)
print(urlString)
manager.get(urlString as String, parameters: params, progress: nil, success: {
(operation, responseObject) in
self.stopAnimation()
let jsonstring = String(data: responseObject! as! Data, encoding: String.Encoding.utf8)
print("jsonstring is:, \(jsonstring!)")
let data = jsonstring!.data(using: .utf8)!
print(data)
do {
if (try JSONSerialization.jsonObject(with: data, options : .allowFragments) as? [Dictionary<String,Any>]) != nil {
let jsonArray = try JSONSerialization.jsonObject(with: data, options : .allowFragments) as! [Dictionary<String,Any>]
print(jsonArray)
} else {
print("bad json")
}
} catch {
print(error)
}
}, failure: {
(operation, error) in
self.stopAnimation()
print(error)
self.alert(message: error.localizedDescription)
})
when I print the json string means they show to string:
"[{\"propertyId\":\"1\",\"inspectionTemplateId\":1118,\"value\":[{\"widgetControllerId\":141,\"value\":\"Flood Summary Name\"},{\"widgetControllerId\":142,\"value\":\"Did the property flood?\"},{\"widgetControllerId\":143,\"value\":\"no\"}]}]"
But when I directly gives the string means it will convert to array.
let jsonstring = "[{\"propertyId\":\"1\",\"inspectionTemplateId\":1118,\"value\":[{\"widgetControllerId\":141,\"value\":\"Flood Summary Name\"},{\"widgetControllerId\":142,\"value\":\"Did the property flood?\"},{\"widgetControllerId\":143,\"value\":\"no\"}]}]"
Just replace AFHTTPResponseSerializer with AFJSONResponseSerializer like this:
var params = NSMutableDictionary()
params = [
"inspectionLogId": inspectionLogIdStr
]
let manager = AFHTTPSessionManager()
manager.requestSerializer = AFJSONRequestSerializer()
manager.responseSerializer = AFJSONResponseSerializer()
manager.requestSerializer.setValue("", forHTTPHeaderField: "apptoken")
manager.requestSerializer.setValue(strAppToken, forHTTPHeaderField: "token")
let urlString:NSString = NSString(format: "%#%#", ApiConstantFile().baseUrlProperty,ApiConstantFile().getTemplateDataUrl)
print(urlString)
manager.get(urlString as String, parameters: params, progress: nil, success: {
(operation, responseObject) in
self.stopAnimation()
print(responseObject)
}, failure: {
(operation, error) in
self.stopAnimation()
print(error)
self.alert(message: error.localizedDescription)
})

I keep getting this particular error when trying to parse a JSON response in Swift:
Error Domain=NSCocoaErrorDomain Code=3840 "No value." UserInfo={NSDebugDescription=No value.}
Code:
let dict = [
"phone": phone,
"firstname": "\(String(describing: firstName))",
"lastname": "\(String(describing: lastName))"
]
as [String: Any]
if let jsonData = try? JSONSerialization.data(withJSONObject: dict, options: []) {
var request = URLRequest(url: URL(string: "\(config.baseURL)employee")!)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
request.timeoutInterval = 30.0
let task = URLSession.shared.dataTask(with: request) { data, response, error in
if error != nil {
DispatchQueue.main.async {
self.alertController.singleButtonAlertController("Error", (error?.localizedDescription)!, self, self.defaultAction)
return
}
}
guard let data_ = data else {
return
}
do {
let jsonObj = try JSONSerialization.jsonObject(with: data_, options: .mutableContainers) as? NSDictionary
guard let parseJSON = jsonObj else {
return
}
self.navigationItem.rightBarButtonItem = self.rightBarButton
let meta = parseJSON["meta"] as? [String:Any]
let status = meta!["status"] as? String
if status == "200" {
isEmployeeModified = true
self.dismiss(animated: true, completion: nil)
} else {
let info = meta!["info"] as? String
let message = meta!["message"] as? String
DispatchQueue.main.async {
self.alertController.singleButtonAlertController(info!, message!, self, self.defaultAction)
}
}
} catch let error as NSError {
print(error)
}
}
task.resume()
I have used similar codes in other parts of the project and everything checks out.
According to this Error, the response from your server is not a valid JSON
Can you use responseString instead of responseJSON like below
Alamofire.request(URL, method: requestMethod, parameters: params).responseString{ response in
print(response)
}
I was able to figure out what was wrong and I'm going to explain this here for future readers. Apparently, I was doing a GET request the wrong way, so when I intend to do a POST request, for some reason, it still sees it as a GET request and that was why I kept getting the response: Error Domain=NSCocoaErrorDomain Code=3840 "No value." UserInfo={NSDebugDescription=No value.}
Below is my refactored code and it works without any hassle:
let dict = [
"phone": phone,
"firstname": firstName,
"lastname": lastName
] as [String : Any]
guard let jsonData = try? JSONSerialization.data(withJSONObject: dict, options: []) else {
return
}
guard let url = URL(string: "\(config.baseURL)employee") else {
return
}
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData as Data
request.timeoutInterval = 10
let session = URLSession.shared
session.dataTask(with: request) { (data, response, error) in
if let response = response {
print("JSON Response: \(response)")
}
if error != nil {
DispatchQueue.main.async {
self.navigationItem.rightBarButtonItem = self.rightBarButton
self.alertController.singleButtonAlertController("Error", (error?.localizedDescription)!, self, self.defaultAction)
return
}
}
if let data = data {
do {
let parseJSON = try JSONSerialization.jsonObject(with: data, options: []) as? NSDictionary
let meta = parseJSON!["meta"] as? [String:Any]
let status = meta!["status"] as? String
if status == "200" {
isEmployeeModified = true
self.dismiss(animated: true, completion: nil)
} else {
let info = meta!["info"] as? String
let message = meta!["message"] as? String
DispatchQueue.main.async {
self.alertController.singleButtonAlertController(info!, message!, self, self.defaultAction)
}
}
} catch {
print(error)
}
}
}.resume()
I want to send following object as body parameter. But serialization is failing:

How can i send that request?. Is it possible with alamofire?
Using Almofire you can achieve this as
let params: [String: Any] = [
"StartAddress":"Colombo",
"EndAddress":"Kandy",
"DepartureAddress":"Kollupitiya, Colombo",
"StartLocation":[
6.9270974,
79.8607731
],
"EndLocation":[
7.2916216,
80.6341326
],
] //Do check your dictionary it must be in correct format
Alamofire.request("yourUrl", method: .post, parameters: params, encoding: JSONEncoding.default)
.responseJSON { response in
print(response)
}
try using:
let session = Foundation.URLSession.shared
let url = URL(string: "Your server url")
var request = URLRequest(url : url!)
request.httpMethod = "POST"
let params :[String:Any] = ["name":"yuyutsu" as Any,"rollno":12 as Any] //Add your params
do {
let jsonData = try JSONSerialization.data(withJSONObject: params, options: .prettyPrinted)
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
session.dataTask(with: request, completionHandler: { data, response, error in
OperationQueue.main.addOperation {
guard error == nil && data != nil else { // check for fundamental networking error
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
// print("response = \(response)")
}
let responseString = String(data: data!, encoding: String.Encoding.utf8)
print("responseString = \(responseString!)")
if let responsedata = responseString!.data(using: String.Encoding.utf8)! as? Data{
do {
let jsonResult:NSDictionary = try JSONSerialization.jsonObject(with: responsedata, options: []) as! NSDictionary
print("Get The Result \(jsonResult)")
if error != nil {
// print("error=\(error)")
}
if let str = jsonResult["success"] as? NSNull {
print("error=\(str)")
}
else {
let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print("Response string : \(responseString)")
}
} catch let error as NSError {
print(error.localizedDescription)
}
}
}
}) .resume()
}catch {
// print("Error -> \(error)")
}
hope this might help you out.
Creating JSON parameters to send it as a post body:
Function:
//MARK:- Create JSON String
func createJSONParameterString(postBody:AnyObject) -> String {
if let objectData = try? JSONSerialization.data(withJSONObject: postBody, options: JSONSerialization.WritingOptions(rawValue: 0)) {
let objectString = String(data: objectData, encoding: .utf8)
return objectString ?? ""
}
return ""
}
Usage:
var postBody = [AnyHashable:Any]()
postBody["device_id"] = "device_ID"
let parameters = createJSONParameterString(postBody: postBody as AnyObject)
print(parameters)
i have solved similar problem using Alamofire and SwiftyJson as follow
let call your object (data )
let json = JSON(data)
let Params :Dictionary = json.dictionaryObject!
and in Alamofire request
Alamofire.request(url, method: .post, parameters: Params , encoding: JSONEncoding.prettyPrinted, headers: nil)
//.validate(statusCode: 200..<300)
.responseJSON { response in
switch response.result
{
case .failure(let error):
case .success(let value):
}
it need to replace this "{ }" with "[ ]"
and alamofire and swift json handle that issue
ex:
[
{
"firstName" : " " ,
"lastName" : " "
},
{
"firstName" : " " ,
"lastName" : " "
}
]
change it to
[
[
"firstName" : " " ,
"lastName" : " "
],
[
"firstName" : " " ,
"lastName" : " "
]
]
