When I print(JSON) I get the files, so the .request works.
But when I am trying to access the "test" key (which exists) I get nil
I get
"I am here"
"now ,I am here"
Alamofire.request(.GET, self.APIBaseUrl , parameters: ["api_key": self.APIkey])
.responseJSON { response in
if let JSON = response.result.value {
print("I am here")
if let str = JSON as? NSDictionary {
print("now , I am here")
if let movieUrlString = str["poster_path"] as? String)! {
print("but now here")
}
EDITED
print(dict)
**dates** = {
maximum = "2015-10-21";
minimum = "2015-09-30";
};
page = 1;
**results** = (
{
adult = 0;
"poster_path" = "/2XegKZ0I4QrvzpEHneigRk6YTB1.jpg";
++(more results)
Try to use more meaningful debug printing statements and variables names. Also you were not using the right variable for subscripting. Fixed example:
Alamofire.request(.GET, self.APIBaseUrl , parameters: ["api_key": self.APIkey]).responseJSON { response in
if let JSON = response.result.value {
print("inside JSON result")
if let dict = JSON as? NSDictionary {
print("inside decoded JSON")
if let results = dict["results"] as? [NSDictionary] {
for result in results {
if let movieUrlString = result["poster_path"] as? String {
print(movieUrlString)
}
}
}
}
}
}

I'm parsing JSON with alamofire in swift. I'm trying to look loop my json but there is something wrong with my code. When looking through code with debugger, my application wont enter at if and for. Whats wrong with my code?
I have to loop my json with "for" and parse my json data.
Alamofire.request(apiToContact, method: .get, encoding: URLEncoding.default, headers: headersq).responseJSON { (response) in
print(response)
if response.result.isSuccess {
guard let resJson = response.result.value else { return }
print(resJson);
if let json = response.result.value as? [String:AnyObject] {
for entry in json {
print("\(entry)") // this is where everything crashes
}
}
if let JSON = response.result.value as? NSDictionary{
for entry in JSON {
print("\(entry)") // this is where everything crashes
}
}
}
if response.result.isFailure {
}
}
Print(response) gives this json.:
SUCCESS: (
{
KoorX = "38.414745";
KoorY = "27.183055";
Yon = 1;
},
{
KoorX = "38.41474";
KoorY = "27.18382667";
Yon = 1;
},
{
KoorX = "38.422255";
KoorY = "27.15055167";
Yon = 1;
}
)
First of all in Swift 3+ a JSON dictionary is [String:Any]
Two issues:
The array is the value for key SUCCESS in the root object.
The fast enumeration syntax for a dictionary is for (key, value) in dictionary
guard let resJson = response.result.value as? [String:Any],
let success = resJson["SUCCESS"] as? [[String:Any]] else { return }
for entry in success {
print(entry)
}
}
This Code Help You
if let locationJSON = response.result.value
{
let locationObject: Dictionary = locationJSON as! Dictionary<String, Any>
self.dataArray = locationObject["data"]as! NSArray
}
I am trying to parse my JSON data and append only those objects into array which meets specified condition. At the moment I have commented out code which fetch all objects from the API and add them into array. However, I would like to limit it so that it only appends objects with "wger.de" value for "license_author" key.
However I am getting error on line:
if eachExercise["license_author"] == "wger.de"
Binary operator '==' cannot be applied to operands of type 'Any?' and 'String'.
However I still wants to keep it as Any object because I would like to fetch both strings and integers data from my API.
This is the code for my parseData() function:
func parseData() {
fetchedExercise = []
let urlPath = "https://wger.de/api/v2/exercise/?format=json&language=2&status=2"
let url = URL(string: urlPath)!
let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
if error != nil {
print("Error while parsing JSON")
}
else {
do {
if let data = data,
let fetchedData = try JSONSerialization.jsonObject(with: data, options: .mutableLeaves) as? [String:Any],
let exercises = fetchedData["results"] as? [[String: Any]] {
// WORKING CODE
/*
for eachExercise in exercises
{
let name = eachExercise["name"] as! String
let description = eachExercise["description"] as! String
self.fetchedExercise.append(Exercise(name: name, description: description))
}
*/
// TESTING
for eachExercise in exercises {
if eachExercise["license_author"] == "wger.de" {
let name = eachExercise["name"] as! String
let description = eachExercise["description"] as! String
let id = eachExercise["id"] as! Int
self.fetchedExercise.append(Exercise(name: name, description: description))
}
}
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
catch {
print("Error while parsing data.")
}
}
}
task.resume()
}
Use the where clause and optional downcast Any to String
for eachExercise in exercises where eachExercise["license_author"] as? String == "wger.de" { ...
You need cast it to String.
if eachExercise["license_author"] as? String == "wger.de" {
}
I am trying to parse the response from Alamofire but I can't figure out how to do it.
This is the JSON Response I get (I want to parse out "result") how is this done?
JSON: {
result = 887957;
status = 0;
}
Swift 3
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
You just need to specify the type of response is Dictionary and then use subscript with dictionary to get value of result.
if let dictionary = response.result.value as? [String: Int] {
let result = dictionary["result"] ?? 0
print(result)
}
if let JSON = response.result.value as? [String : Any] {
let result = JSON["result"] as? Int
let status = JSON["status"] as? Int
print("Result \(result) Status \(status)")
}
As per latest Almofire Lib and Swift 3.0 with proper validation:
case .success(_):
if ((response.result.value) != nil) {
var responseData = JSON(response.result.value!)
//Userdefaults helps to store session data locally just like sharedpreference in android
if (response.response ? .statusCode == 200) {
let result: Int = responseData["result"].int!
let status: Int = responseData["status"].int!
}
}
case .failure(_):
print(response.result)
}
I'm trying to use football-data.org api. I wrote some code same with before I did sample. But this api is using token and I didn't figured out how to add and do that.
I did these code and nothing happens :
func getData(){
let url = NSMutableURLRequest(URL: NSURL(string: "http://api.football-data.org/v1/soccerseasons/424/fixtures"))
url.addValue("my token is here", forHTTPHeaderField: "X-Auth-Token")
url.HTTPMethod = "GET"
let task = NSURLSession.sharedSession().dataTaskWithRequest(url) { (data, response, error) in
self.setLabels(data!)
}
task.resume()
}
func setLabels(MatchData: NSData){
//var jsonError: NSError?
do{
let json = try NSJSONSerialization.JSONObjectWithData(MatchData, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary
if let sys = json["soccerseason"] as? NSDictionary{
if (sys["href"] as? String) != nil{
let seasonsUrl = sys["href"] as! String
print(seasonsUrl)
}
}
}
catch{
//error
}
}
I'm not getting value or something. I'm new with json. What's wrong in my code?
"soccerseason" is in "_links", like this:
if let links = json["_links"] as? [String:AnyObject],
sys = links["soccerseason"] as? [String:String],
seasonsUrl = sys["href"] {
print(seasonsUrl)
}
This is for the main one.
I've also noticed there's one (the same one, actually) in each dictionary in the main array:
if let fixtures = json["fixtures"] as? [[String:AnyObject]] {
for fixture in fixtures {
if let links = fixture["_links"] as? [String:AnyObject],
sys = links["soccerseason"] as? [String:String],
seasonsUrl = sys["href"] {
print(seasonsUrl)
}
}
}
The URLs are in the _links part in each dictionary in the fixtures array:
if let fixtures = json["fixtures"] as? [[String:AnyObject]] {
for fixture in fixtures {
if let links = fixture["_links"] as? [String:[String:String]],
season = links["soccerseason"],
seasonsUrl = season["href"],
awayTeam = links["awayTeam"],
awayTeamUrl = awayTeam["href"] {
print(seasonsUrl)
print(awayTeamUrl)
}
}
}
And awayTeamName and homeTeamName are at the same level than _links inside the array of dictionaries:
if let fixtures = json["fixtures"] as? [[String:AnyObject]] {
for fixture in fixtures {
if let awayTeamName = fixture["awayTeamName"] as? String,
homeTeamName = fixture["homeTeamName"] as? String {
print(awayTeamName)
print(homeTeamName)
}
}
}
I try to grab data from JSON (http://www.openligadb.de/api/getmatchdata/bl1/2014/15). I want to get every single game with the goals, location, team ...
I tried this but it won't work.
let url = "http://www.openligadb.de/api/getmatchdata/bl1/2014/15"
//parse url
if let JSONData = NSData(contentsOfURL: NSURL(string: url)!) {
if let json = (try? NSJSONSerialization.JSONObjectWithData(JSONData, options: [])) as? NSDictionary {
//handle json
}
}
It doesn't steps in the 2nd if-statement (if let json = (try?...).
I hope you could help me.
Edit get data of dictionaries:
//Data Team1
if let team1 = object["Team1"] as? NSDictionary {
if let name = team1["TeamName"] as? String {
print("Name Team1: \(name)")
}
if let logo = team1["TeamIconUrl"] as? String {
print("Logo Team1: \(logo)")
}
// Etc.
}
What you need to do is to understand your JSON structure: you have an array first, not a dictionary.
This array has dictionaries, each of them holding an array of dictionaries.
It may sound complex but it's actually simple, you just follow the structure of your JSON and decode the values with the correct type.
In JSON, an array starts with [ and a dictionary starts with { (also, be careful not to confuse this JSON syntax with Swift's arrays and dictionaries one).
Your code could be something like this, for example:
do {
let url = "http://www.openligadb.de/api/getmatchdata/bl1/2014/15"
if let url = NSURL(string: url),
JSONData = NSData(contentsOfURL: url),
jsonArray = try NSJSONSerialization.JSONObjectWithData(JSONData, options: []) as? NSArray {
for object in jsonArray {
if let goalsArray = object["Goals"] as? NSArray {
// Each "goal" is a dictionary
for goal in goalsArray {
print(goal)
if let name = goal["GoalGetterName"] as? String {
print("Name: \(name)")
}
if let ID = goal["GoalID"] as? Int {
print("ID: \(ID)")
}
// Etc.
}
}
}
}
} catch {
print(error)
}
UPDATE: you're almost there! But "Team1" is a dictionary, not an array. :)
Here's the solution:
do {
let url = "http://www.openligadb.de/api/getmatchdata/bl1/2014/15"
if let url = NSURL(string: url),
JSONData = NSData(contentsOfURL: url),
jsonArray = try NSJSONSerialization.JSONObjectWithData(JSONData, options: []) as? NSArray {
for object in jsonArray {
if let team1 = object["Team1"] as? NSDictionary {
if let name = team1["TeamName"] as? String {
print("Name Team1: \(name)")
}
if let logo = team1["TeamIconUrl"] as? String {
print("Logo Team1: \(logo)")
}
}
}
}
} catch {
print(error)
}
