Swift: HTTP load failed (error code: 100) - json

When i run this code it will give me this error:
2018-05-03 18:06:05.605035+0200 FNStats[4225:1826491] Task
.<1> HTTP load failed (error

FNStats[4225:1826493] Task .<1>
finished with error - code: 100
Can someone explaine to me what I am doing wrong!
let urlString = "https://api.fortnitetracker.com/v1/profile/pc/Danikemper010"
let url = NSURL(string: urlString)!
var request = URLRequest(url: url as URL)
request.setValue("TRN-Api-Key: c400d2a8-8a99-45e7-a62b-3cef2d74ce14", forHTTPHeaderField: "TRN-Api-Key: c400d2a8-8a99-45e7-a62b-3cef2d74ce14")
URLSession.shared.dataTask(with: request) { data, response, error in
if let responseData = data
{
do{
let json = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments)
print(json)
}catch{
print("Could not serialize")
}
}
}.resume()

This worked for me. The header field is "TRN-Api-Key" and the value for that field is your key.
let urlString = "https://api.fortnitetracker.com/v1/profile/pc/Danikemper010"
let url = NSURL(string: urlString)!
var request = URLRequest(url: url as URL)
request.setValue("c400d2a8-8a99-45e7-a62b-3cef2d74ce14", forHTTPHeaderField: "TRN-Api-Key")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
if let responseData = data {
print("We have some data")
do{
let json = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments)
print(json)
}catch{
print("Could not serialize")

how to make HTTPRequest with json in swift

I am making an ios application. I am new to swift and not able to understand my code. can anyone please help me to understand what is going on with my code.
This is login application on adding email id if the email exist it should go to next view controller and if not then it should give error. I am getting difficulty in understanding my code .
Here is my code:
class checkLoginViewController: UIViewController {
#IBOutlet weak var checkUsernametextfield: UITextField!
#IBAction func checkUsernameButton(_ sender: UIButton) {
print("Clicked On SUbmit !!!!")
//Read Value from Text
let email = checkUsernametextfield.text
let myUrl = URL(string: "http://192.168.0.117/rest/signup.php");
var request = URLRequest(url:myUrl!)
request.httpMethod = "POST"// Compose a query string
let postString = "email=\(String(describing: email))";
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
}
// You can print out response object
print("response = \(String(describing: response))")
//Let's convert response sent from a server side script to a NSDictionary object:
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
if let parseJSON = json {
// Now we can access value of First Name by its key
let emailValue = parseJSON["email"] as? String
print("email: \(String(describing: emailValue))")
}
} catch {
print(error)
}
}
task.resume()
Output:
Clicked On SUbmit !!!! response = Optional( { URL: http://192.168.0.117/rest/signup.php } { Status
Code: 200, Headers {
Connection = (
"Keep-Alive"
);
"Content-Length" = (
61
);
"Content-Type" = (
"application/json"
);
Date = (
"Mon, 12 Mar 2018 06:35:58 GMT"
);
"Keep-Alive" = (
"timeout=5, max=100"
);
Server = (
"Apache/2.4.27 (Ubuntu)"
); } }) email: nil
Maybe try this. Hope it works.
let url = URL(string:"http://192.168.0.117/rest/signup.php")
let parameters = ["email": checkUsernametextfield.text]
var request = URLRequest(url : url!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject:parameters, options: [])
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let session = URLSession.shared
session.dataTask(with: request, completionHandler: { (data, response, error) in
if let data = data {
do {
let json = try? JSONSerialization.jsonObject(with: data, options: []) as! Dictionary<String, Any>
if let json = json {
print("HERE SHOULD BE YOUR JSON \(json)")
}
}
} else {
print("Error \(String(describing: error?.localizedDescription))")
}
}).resume()
Here is way to send request.
enter code here
static func downloadConfig(url:URL, completion:#escaping (_ sucess:Bool , _ jsonObject: [String: String]?)->() ) {
var request = URLRequest(url: url)
request.setValue("application/x-www-form-urlencoded",
forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
let postString = "id=13&name=Jack"
request.httpBody = postString.data(using: .utf8)
URLSession.shared.dataTask(with: request) { (data,response,error) in
if let data = data ,let httpURLResponse = response as? HTTPURLResponse, httpURLResponse.statusCode == 200 {
do {
if let todoJSON = try JSONSerialization.jsonObject(with: data, options: []) as? [String: String]{
completion(true,todoJSON)
}
else
{
completion(false,nil)
}
}
catch {
//erro parsing
completion(false,nil)
}
}
else
{
completion(false,nil)
}
}.resume()
}
use this download json function in this way.
//Download Json File
let base_url = "base_url"
let urlstr = String.init(format: "%#", base_url)
let url = URL(string: urlstr)
GameUtil.downloadConfig(url: url!) {
(sucess: Bool , jsonObject: [String:String]?) in
if sucess , jsonObject != nil
{
self.configJson = jsonObject!
}
}

Wait until JSON call is finished

I have this code in a part of my app:
let myUrl = NSURL(string: "http://aesolutions.ddns.net/data/load_tasks_calendar.php");
let request = NSMutableURLRequest(url: myUrl! as URL);
request.httpMethod = "POST";
let postString = "id_class=\(UserDefaults.standard.string(forKey: "userClass")!)";
request.httpBody = postString.data(using: String.Encoding.utf8);
MenuViewController.tasksCalendarArray.removeAll()
let task = URLSession.shared.dataTask(with: request as URLRequest){
data, response, error in
if error != nil{
print("error1=\(String(describing: error))")
return
}
var _: NSError?
do{
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSArray
if let parseJSON: NSArray = json {
for index in 0...parseJSON.count-1 {
if (parseJSON[index] is NSNull){
MenuViewController.tasksCalendarArray.removeAll()
}else{
let compito = parseJSON[index] as! [String:Any]
let task = tasks.init(taskId: compito["id"] as! String,taskType: compito["type"] as! String,taskSubject: compito["subject"] as! String,taskDate: compito["date"] as! String,taskComment: compito["comment"] as! String)
MenuViewController.tasksCalendarArray.append(task)
}
}
}
}catch{
print("error2=\(error)")
return
}
DispatchQueue.main.async(execute: {
self.performSegue(withIdentifier: "loginToDiary", sender: self)
});
}
task.resume();
I want to perform the segue only when I load all the array. How can I wait until the json is terminated or is done correctly? Because I noticed that sometimes it is correct and other times it performs the segue and so the array is empty and then in the app there are errors.
Can someone help me also adding an alert with a kind of "loading message" to wait that the array is loading?

Sending an image via POST in a Swift Playground

I try to send an image to the MS Cognitive Services Visions API in a Swift Playground.
The message I get as response is:
Response ["requestId": …, "code": InternalServerError, "message": Internal server error.]
Here is the code I use
let image = #imageLiteral(resourceName: "paper.jpg")
let imageData = UIImageJPEGRepresentation(image, 1)!
let endpoint = ("https://westeurope.api.cognitive.microsoft.com/vision/v1.0/analyze?visualFeatures=Description,Categories,Tags&subscription-key=\(subscriptionKey)")
let requestURL = URL(string: endpoint)!
let session = URLSession(configuration: URLSessionConfiguration.default)
var request:URLRequest = URLRequest(url: requestURL)
request.httpMethod = "POST"
// Image
let boundary = UUID().uuidString
request.addValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
var body = NSMutableData()
body.append("\r\n--\(boundary)\r\n".data(using: .utf8)!)
body.append("Content-Disposition: form-data; name=\"file\"; filename=\"image.jpg\"\\r\n".data(using: .utf8)!)

body.append(imageData)
body.append("\r\n--\(boundary)\r\n".data(using: .utf8)!)

print("Response \(json)")
} catch let error as Error {

}
}

I suspect I am not sending the image correctly. Any ideas?
It's probably best to not bother with a multi-part MIME, especially when you consider that the other Cognitive Service properties (namely Face and Emotion) don't support it.
let subscriptionKey = "YOUR-KEY"
let image = #imageLiteral(resourceName:"monkey.jpg")
let imageData = UIImageJPEGRepresentation(image, 1.0)!
let endpoint = ("https://westus.api.cognitive.microsoft.com/vision/v1.0/analyze?visualFeatures=Description,Categories,Tags")
let requestURL = URL(string: endpoint)!
let session = URLSession(configuration: URLSessionConfiguration.default)
var request:URLRequest = URLRequest(url: requestURL)
request.httpMethod = "POST"
request.addValue("application/octet-stream", forHTTPHeaderField: "Content-Type")
request.addValue(subscriptionKey, forHTTPHeaderField: "Ocp-Apim-Subscription-Key")
request.httpBody = imageData
var semaphore = DispatchSemaphore.init(value: 0);
let task = session.dataTask(with: request) { (data, response, error) in
guard let data = data, error == nil else { return }
do {
let json = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as! [String:Any]

How to make HTTP Post request with JSON body in Swift?

I'm trying to make an HTTP post request with a JSON body :
How to be able to add an NSdictionnary to the HTTP request body.
Here is my code, it doesn't seem to work properly.
var entry1 = Response(IdQuestion: 6510,IdProposition: 10,Time: 30)
var entry2 = Response(IdQuestion: 8284,IdProposition: 10,Time: 30)
Responses.append(entry1)
Responses.append(entry2)

request.HTTPBody = data
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in

The following Swift 5 Playground code shows a possible way to solve your problem using JSONSerialization and URLSession:

let url = URL(string: "http://localhost:8080/new")!
let jsonDict = ["firstName": "Jane", "lastName": "Doe"]
let jsonData = try! JSONSerialization.data(withJSONObject: jsonDict, options: [])
var request = URLRequest(url: url)
request.httpMethod = "post"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
if let error = error {
print("error:", error)
return
}
do {
guard let data = data else { return }
guard let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: AnyObject] else { return }
print("json:", json)

request.setValue("application/json", forHTTPHeaderField: "Accept")
request.httpMethod = "POST"
let postString = "ChangeAccordingtoyourdata=\(paramOne)&ChangeAccordingtoyourdata2=\(paramTwo)"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in

print("error=\(error)")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors

SVProgressHUD.showError(withStatus: "Request has not submitted successfully.\nPlease try after some time")
}
let responseString = String(data: data, encoding: .utf8)

Perfect nRewik answer updated to 2019:
Make the dictionary:
let dic = [
"username":u,
"password":p,
"gems":g ]
Assemble it like this:
var jsonData:Data?
do {
jsonData = try JSONSerialization.data(
withJSONObject: dic,
options: .prettyPrinted)
} catch {
print(error.localizedDescription)
}
Create the request exactly like this, notice it is a "post"
let url = URL(string: "https://blah.com/server/dudes/decide/this")!
var request = URLRequest(url: url)
request.setValue("application/json; charset=utf-8",
forHTTPHeaderField: "Content-Type")
request.setValue("application/json; charset=utf-8",
forHTTPHeaderField: "Accept")
request.httpMethod = "POST"
request.httpBody = jsonData
Then send, checking for either a networking error (so, no bandwidth etc) or an error response from the server:
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
// check for fundamental networking error
print("fundamental networking error=\(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: .utf8)
print("responseString = \(responseString)")
Fortunately it's now that easy.
you can do something like this:
func HTTPPostJSON(url: String, data: NSData,
callback: (String, String?) -> Void) {
var request = NSMutableURLRequest(URL: NSURL(string: url)!)
request.HTTPMethod = "POST"
request.addValue("application/json",forHTTPHeaderField: "Content-Type")
request.addValue("application/json",forHTTPHeaderField: "Accept")
request.HTTPBody = data
HTTPsendRequest(request, callback: callback)
}
func HTTPsendRequest(request: NSMutableURLRequest,
callback: (String, String?) -> Void) {
let task = NSURLSession.sharedSession()
.dataTaskWithRequest(request) {
(data, response, error) -> Void in
if (error != nil) {
callback("", error.localizedDescription)
} else {
callback(NSString(data: data,
encoding: NSUTF8StringEncoding)! as String, nil)
}
}
task.resume()
}
//use
var data :Dictionary<String, AnyObject> = yourDictionaryData<--
var requestNSData:NSData = NSJSONSerialization.dataWithJSONObject(request, options:NSJSONWritingOptions(0), error: &err)!
HTTPPostJSON("http://yourPosturl..", data: requestNSData) { (response, error) -> Void in
if error != nil{
//error
return;
}
println(response);
}
Swift4 - Apple Solution "POST" and "Codable"
Uploading Data to a Website using request.httpmethod = "Post" and Codable Stucts:
#see: Listing 2 Configuring a URL request
let userlogin = User(username: username, password: password, deviceid:UIDevice.current.identifierForVendor!.uuidString)
guard let uploadData = try? JSONEncoder().encode(userlogin) else {
print("Error UploadData: ")
return
}
let urlUser = URL(string: APPURL.apiURL)!
var request = URLRequest(url: urlUser)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
var responseStatus = 0
let task = URLSession.shared.uploadTask(with: request, from: uploadData) { data, response, error in
if let error = error {
let code = (error as NSError).code
print("Error:\(code) : \(error.localizedDescription)")
completion(code)
return
}
guard let response = response as? HTTPURLResponse else {
print("Invalid response")
return
}
// do your response handling here ...
No library required, simply use URLSession
here is an example:
let sampleData = ["key": "Value"]
var urlRequest = URLRequest(url: URL(string: "https://REPLACE.ME")!)
let urlSession = URLSession = URLSession(configuration: .default)
let encoder = JSONEncoder()
// inside a throwing function or wrap it in a doCatch block
let jsonData = try encoder.encode(sampleData)
urlRequest.httpMethod = "POST"
urlRequest.addValue("application/json",forHTTPHeaderField: "Content-Type")
urlRequest.httpBody = jsonData
let task = urlSession.dataTask(with: urlRequest) { data, response, error in
let statusCode = (response as? HTTPURLResponse)?.statusCode
print("💁🏻‍♂️ \(statusCode)")
}
task.resume()

For a Codable / Encodable type in Swift 4+
Use a JSONEncoder to transform the object into Data:
let jsonObject = ... // Encodable or Codable
guard let jsonData = try? JSONEncoder().encode(jsonObject) else {
fatalError("encoding error")
}
Then set that encoded object as the httpBody of the URLRequest:
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
Swift 5.5
As of Swift 5.5, we now have another alternative using async/await:
// Form the POST request:
let url = URL(string: "http://example.com/login")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
// Use the async variant of URLSession to make an HTTP POST request:
let (data, response) = try await URLSession.shared.upload(for: request, from: requestData)
Complete example:
struct LoginResponse: Decodable {
let id: String
let name: String
}
func login(_ username: String, _ password: String) async throws -> LoginResponse {
struct RequestData: Encodable {
let username: String
let password: String
}
// Encode data to JSON to send in the POST request body:
let encoder = JSONEncoder()
let requestData = try encoder.encode(RequestData(username: username, password: password))
// Form the POST request:
let url = URL(string: "http://example.com/login")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
// Use the async variant of URLSession to make an HTTP POST request:
let (data, response) = try await URLSession.shared.upload(for: request, from: requestData)
print("HTTPURLResponse:", response)
print("The response body is:", String(decoding: data, as: UTF8.self))
// Parse the JSON response:
return try JSONDecoder().decode(LoginResponse.self, from: data)
}
Usage
You must call it in an async context (so you can await it). One way is using a Task:
Task {
do {
let loginResponse = try await login("user1", "mypassword")
print("Login successful for user with id:", loginResponse.id)
} catch {
print(error)
}
}
// prepare json data
let mapDict = [ "1":"First", "2":"Second"]
let json = [ "title":"ABC" , "dict": mapDict ] as [String : Any]
let jsonData : NSData = NSKeyedArchiver.archivedData(withRootObject: json) as NSData
// create post request
let url = NSURL(string: "http://httpbin.org/post")!
let request = NSMutableURLRequest(url: url as URL)
request.httpMethod = "POST"
// insert json data to the request
request.httpBody = jsonData as Data
let task = URLSession.shared.dataTask(with: request as URLRequest){ data,response,error in
if error != nil{
return
}
do {
let result = try JSONSerialization.jsonObject(with: data!, options: []) as? [String:AnyObject]
print("Result",result!)
} catch {
print("Error -> \(error)")
}
}
task.resume()
var request = URLRequest(url: URL(string: "your URL")!)
request.httpMethod = "POST"
let postString = String(format: "email=%#&lang=%#", arguments: [txt_emailVirify.text!, language!])
print(postString)
emailString = txt_emailVirify.text!
request.httpBody = postString.data(using: .utf8)
request.addValue("delta141forceSEAL8PARA9MARCOSBRAHMOS", forHTTPHeaderField: "Authorization")
request.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
