Get JSON in Swift - json

This is my code to get JSON, and it's work with this url I found on an other questions : http://binaenaleyh.net/dusor/.
But, when I use it with this url : http://www.netcampus.fr/api/schools, it didn't work at all. I have an error who said : "exc_breakpoint (code=exc_i386_bpt subcode=0x0)"
Is my code wrong, or is it the JSON data ?
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
var myData:NSData = getJSON("http://www.netcampus.fr/api/schools")
println(myData) // show me data
var myDict:NSDictionary = parseJSON(myData)
println(myDict)
}
func getJSON(urlToRequest: String) -> NSData{
return NSData(contentsOfURL: NSURL(string: urlToRequest))
}
func parseJSON(inputData: NSData) -> NSDictionary{
var error: NSError?
var boardsDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(inputData, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary // error here
return boardsDictionary
}
}

Your parseJSON method crashes when parsing the second JSON. NSJSONSerialization maps its contents to an array and you are expecting a dictionary:
var boardsDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(inputData, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary // error here

As #reecon pointed out ,your code should be like this
//JSON Parsing
func JSONParsingSample() {
var myData:NSData = getJSON("http://www.netcampus.fr/api/schools")
//println(myData) // show me data
var myDict:NSArray = parseJSON(myData)
println(myDict)
}
func getJSON(urlToRequest: String) -> NSData{
return NSData(contentsOfURL: NSURL(string: urlToRequest))
}
func parseJSON(inputData: NSData) -> NSArray{
var error: NSError?
var boardsDictionary: NSArray = NSJSONSerialization.JSONObjectWithData(inputData, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSArray
return boardsDictionary
}
//end

let urlString = "webAPI"
var request = URLRequest(url: URL(string: urlString)!)
let session = URLSession.shared
request.httpMethod = "GET"
session.dataTask(with: request)
{
data, response, error in
if error != nil
{
print(error!.localizedDescription)
return
}
do
{
let jsonResult: NSDictionary? = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary
self.dict = jsonResult as! NSMutableDictionary
print("Synchronous\(jsonResult)")
DispatchQueue.main.async
{
let url = URL(string: ((((self.dict.value(forKey: "sources") as! NSArray).object(at: 5) as! NSDictionary).value(forKey: "urlsToLogos") as? NSDictionary)?.value(forKey: "small") as? String)!)
let data = try? Data(contentsOf: url!)
}
}
catch
{
print"error"
}
}.resume()

response Data is nil

I am getting response data nil.
func fetchSinglePageData() {
var response: NSData?
var errors: NSError?
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
response = NSData(contentsOfFile:"url...?project_id=(self.projectID)&project_page=Request", options: NSDataReadingOptions(0), error: &errors)
print("LatestURL Single page:(response)")
if response == nil {
var alertview = UIAlertView(title: "Network Error", message: "Data not received due to network connection.Try again...", delegate: self, cancelButtonTitle: "Ok")
alertview.show()
}
else{
let jsonDict: NSDictionary = NSJSONSerialization.JSONObjectWithData(response!, options: nil, error: &errors) as NSDictionary
print("JSON Response Single page:(jsonDict)")
var statuses = [NSObject : AnyObject]()
self.lblstartTime?.text = jsonDict["start_time"] as? String

self.lblcompletionTime?.text = jsonDict["completion_time"] as? String
self.lblManager?.text = jsonDict["manager"] as? String

}
project_id is string which is recevied from presvious page which is correctly working.
In swift 3

This is my answer as per Jitendra Solanki answer i have made changes to code and it is now working in Swift 1.2
After a quick look, maybe \ missing:
NSData(contentsOfFile:"url...?project_id=\(self.projectID)&project_page=Request"
In this line:
response = NSData(contentsOfFile:"url...?project_id=(self.projectID)&project_page=Request", options: NSDataReadingOptions(0), error: &errors)
you have project_id=(self.projectID), to use interpolation you should instead have project_id=\(self.projectID)
I would suggest that you separate the code to generate your full URL, then print the URL to the console and ensure that it is what you would expect.
Then you can visit the url yourself and check to see what the server returns, then once you know you have the correct URL and response you can then work to deserialise the response
EDIT: updated with URLSession (Swift 3 version)
let defaultSession = URLSession(configuration: URLSessionConfiguration.default)
var dataTask: URLSessionDataTask?
let projectID = 12
let url = URL(string: "http://phpyouth.com/clients/halfpricedgrannyflats/app/app_response.php?project_id=\(projectID)&project_page=Request")
dataTask = defaultSession.dataTask(with: url!) {
data, response, error in
if let error = error {
print(error.localizedDescription)
} else if let httpResponse = response as? HTTPURLResponse {
if httpResponse.statusCode == 200 {
if let responseData = data {
if let json = try? JSONSerialization.jsonObject(with: responseData, options: .allowFragments) as? [String:AnyObject] {
print(json)
}
}
}
}

dataTask?.resume()

Struct Init with JSON and flatMap

I'm having a problem with the following code. I'm downloading a list of actors in JSON and I want to populate Struct Actor with the received data. Everything works great until I try to flatMap on the received data and try to initialize the struct Actor. When I try to compile the code i get the error: Cannot assign value of type '()' to type [Actor]. The error corresponds to a line in viewDidLoad actorsList = downloadActors() Would anybody have any recommendation who to solve this?
import UIKit
func downloadActors() {
var request = URLRequest(url: URL(string: "url...")!)
request.httpMethod = "POST"
let postString = "actorGroup=\("Superhero")"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
DispatchQueue.main.async {
guard let data = data, error == nil else {
print("error=\(error)")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {
print("error : statusCode should be 200 but is \(httpStatus.statusCode)")
print("response = \(response)")
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode == 200 {
do {
let json = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers) as? [String: AnyObject]
guard let actorsJSON = json?["response"] as? [[String : AnyObject]] else {
return
}
} catch {
print("catch error")
}
}
}
}
task.resume()
}
func loadActors() -> [Actor] {
if let actors = actorsJSON as? [[String : AnyObject]] {
return actors.flatMap(Actor.init)
}
}
let actorsArray = loadActors()
class MasterViewController: UITableViewController {
var actorsList = [Actor]()
var detailViewController: DetailViewController? = nil
var objects = [Any]()
override func viewDidLoad() {
super.viewDidLoad()
actorsList = downloadActors()
print(actorsList)
Struct Actors is as follows:
struct Job {
let actorGroup: String
let actorName: String
}
extension Actor: JSONDecodable {
init?(JSON: [String : AnyObject]) {
guard let actorGroup = JSON["actorGroup"] as? String, let actorName = JSON["actorName"] as? String else {
return nil
}
self. actorGroup = actorGroup
self. actorName = actorName
}
}
let listActors = actorsJSON as? [[String : AnyObject]] {
Should be:
if let listActors = actorsJSON as? [[String : AnyObject]] {
Edit: For more info I'd like to add Vadian's comment:
Very confusing code. What does the function in the middle of the do block? Why do you type-check actorsJSON twice? The computed property is let listActors... which should be probably an optional binding (if let ... ). Further .mutableContainers is completely nonsense in Swift. And finally a JSON dictionary is [String:Any] in Swift 3.

json data not getting loaded into UITextView in swift

class ViewController:ViewController,UITextViewDelegate{
#IBOutlet weak var newTextView: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
newTextView.delegate = self
dataFun()
}
func dataFun()
{
let url : String = "http:xyz/abc"
let request : NSMutableURLRequest = NSMutableURLRequest()
request.URL = NSURL(string: url)
request.HTTPMethod = "GET"
print("Start")
let session = NSURLSession.sharedSession()
session.dataTaskWithRequest(request) { (data, response, error) -> Void in
do {
let jsonResult: NSDictionary! = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions.MutableContainers) as? NSDictionary
print("In method\(jsonResult)")
// let data = jsonResult["description"]
// print(data!)
if (jsonResult != nil)
{
// process jsonResult
print("Data added")
let test:String = jsonResult["description"] as! String
print(test)
self.newTextView.text = test
} else {
print("No Data")
// couldn't load JSON, look at error
}
}
catch {
print("Error Occured")
}
}
.resume()
}
In my app I am going to call services from API
I can see my json data in console.
that data is not show in textviewController
it shows fatal error:
unexpectedly found nil while unwrapping an Optional value
and then crash the app
Make sure #IBOutlet weak var newTextView: UITextView! is set up correctly.
Make sure let test:String = jsonResult["description"] as! String doesn't crash. JSON has field description and it's a string.

How to parse JSON in Swift using NSURLSession

I am trying to parse JSON but getting this error:
type of expression is ambiguous without more context
My code is:
func jsonParser() {
let urlPath = "http://headers.jsontest.com/"
let endpoint = NSURL(string: urlPath)
let request = NSMutableURLRequest(URL:endpoint!)
let session = NSURLSession.sharedSession()
NSURLSession.sharedSession().dataTaskWithRequest(request){ (data, response, error) throws -> Void in
if error != nil {
print("Get Error")
}else{
//var error:NSError?
do {
let json:AnyObject = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions(rawValue: 0)) as? NSDictionary
print(json)
} catch let error as NSError {
// error handling
print(error?.localizedDescription)
}
}
}
//task.resume()
}
This is working fine with out try catch in Xcode 6.4 but this is not working in Xcode 7.
Don't declare an AnyObject type for your decoded object since you want it to be an NSDictionary and you're performing a conversion to do this.
Also it's better to use zero options for NSJSONSerialization instead of random ones.
In my example I've also used a custom error type just for demonstration.
Note, if you're using a custom error type, you have to also include a generic catch to be exhaustive (in this example, with a simple downcasting to NSError).
enum JSONError: String, ErrorType {
case NoData = "ERROR: no data"
case ConversionFailed = "ERROR: conversion from JSON failed"
}
func jsonParser() {
let urlPath = "http://headers.jsontest.com/"
guard let endpoint = NSURL(string: urlPath) else {
print("Error creating endpoint")
return
}
let request = NSMutableURLRequest(URL:endpoint)
NSURLSession.sharedSession().dataTaskWithRequest(request) { (data, response, error) in
do {
guard let data = data else {
throw JSONError.NoData
}
guard let json = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? NSDictionary else {
throw JSONError.ConversionFailed
}
print(json)
} catch let error as JSONError {
print(error.rawValue)
} catch let error as NSError {
print(error.debugDescription)
}
}.resume()
}
The same with Swift 3.0.2:
enum JSONError: String, Error {
case NoData = "ERROR: no data"
case ConversionFailed = "ERROR: conversion from JSON failed"
}
func jsonParser() {
let urlPath = "http://headers.jsontest.com/"
guard let endpoint = URL(string: urlPath) else {
print("Error creating endpoint")
return
}
URLSession.shared.dataTask(with: endpoint) { (data, response, error) in
do {
guard let data = data else {
throw JSONError.NoData
}
guard let json = try JSONSerialization.jsonObject(with: data, options: []) as? NSDictionary else {
throw JSONError.ConversionFailed
}
print(json)
} catch let error as JSONError {
print(error.rawValue)
} catch let error as NSError {
print(error.debugDescription)
}
}.resume()
}
Apple declare here.
func dataTaskWithRequest(request: NSURLRequest, completionHandler: (NSData?, NSURLResponse?, NSError?) -> Void) -> NSURLSessionDataTask
Fix it:
NSURLSession.sharedSession().dataTaskWithRequest(request) { (data, response, error) -> Void in
// Your handle response here!
}
UPDATE:
func jsonParser() {
let urlPath = "http://headers.jsontest.com/"
let endpoint = NSURL(string: urlPath)
let request = NSMutableURLRequest(URL:endpoint!)
NSURLSession.sharedSession().dataTaskWithRequest(request) { (data, response, error) -> Void in
print(error)
}.resume()
}
RESULT:
Optional(Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSUnderlyingError=0x7f8873f148d0 {Error Domain=kCFErrorDomainCFNetwork Code=-1022 "(null)"}, NSErrorFailingURLStringKey=http://headers.jsontest.com/, NSErrorFailingURLKey=http://headers.jsontest.com/, NSLocalizedDescription=The resource could not be loaded because the App >Transport Security policy requires the use of a secure connection.})

Here is the simplest way to parse JSON using NSUrlSession.,
let PARAMS = "{\"params1\":\"%#\",\"Params2\":\"%#\",\"params3\":\"%#\"}"
let URL = "your url here"
on submit button write this code.,
let urlStr = String(format: "%#",URL)
let jsonString = String(format:PARAMS, params1value,params2value,params3value )
// Encode your data here
let jsonData = jsonString.data(using:.utf8)
var request = URLRequest(url: URL(string: urlStr)!)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
//set your method type here
request.httpMethod = "POST"
request.httpBody = jsonData
let configuration = URLSessionConfiguration.default
// create a session here
let session = URLSession(configuration: configuration, delegate: nil, delegateQueue: OperationQueue.main)
let task = session.dataTask(with: request) {(data , response, error) in
if(error != nil){
print("Error \(String(describing: error))")
}
else {
do {
let fetchedDataDictionary = try JSONSerialization.jsonObject(with: data!, options: []) as? NSDictionary
print(fetchedDataDictionary!)
let message = fetchedDataDictionary?["response key here"] as! String
if message == "your response string" {
print(message)
}
else {
self.dataArray = (fetchedDataDictionary?["data"] as! NSArray)
}

Parse a JSON array

i am working on a way to parse json from the web in my app.
Source: http://api.randomuser.me/
My Code:
var bytes: NSMutableData?
#IBAction func loadJson(sender: AnyObject) {
let request = NSURLRequest(URL: NSURL(string: "http://api.randomuser.me/")!)
let loader = NSURLConnection(request: request, delegate: self, startImmediately: true)
}
func connection(didReceiveResponse: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
self.bytes = NSMutableData()
}
func connection(connection: NSURLConnection!, didReceiveData conData: NSData!) {
self.bytes?.appendData(conData)
}
func connectionDidFinishLoading(connection: NSURLConnection!) {
let jsonResult: Dictionary = NSJSONSerialization.JSONObjectWithData(self.bytes!, options: NSJSONReadingOptions.MutableContainers, error: nil) as! Dictionary<String, AnyObject>
let results: NSArray = jsonResult["results"]! as! NSArray
println(results)
for result in results {
// Works
println(result)
// Works
println(result["seed"])
// Does not work !!! why?
println(result["user"]["email"])
}
}
Why can't I get the email from the array?
If you want you can take a look at the json in the link above.
By using SwiftyJSON you can handle your JSON data easily this way:
#IBAction func loadJson(sender: AnyObject) {
let baseURL = NSURL(string: "http://api.randomuser.me/")
let userData = NSData(contentsOfURL: baseURL!)
let json = JSON(data: userData!)
let seeds = json["results"][0]["seed"].stringValue
let email = json["results"][0]["user"]["email"].stringValue
println(seeds) //1bbefb89fc47c81501
println(email) //luz.hidalgo44#example.com
}
Hope this will help.
