I am unable to post a request in swift. It worked perfectly with my older version of xcode. But now when I run it shows the following error message : UserInfo={NSLocalizedDescription=An SSL error has occurred and a secure connection to the server cannot be made.,

I am sending bearer token in header using urlsession but I always get the result as unauthorized. I have seen the server log. I am getting body in there but not header.
let key = UserDefaults.standard.object(forKey: "loginKey") as! String
print(key)
let url = NSURL(string: baseurl+"***")
let request = NSMutableURLRequest(url: url! as URL)
request.httpMethod = "GET"
request.addValue("Bearer " + key, forHTTPHeaderField: "Authorization")
let task = URLSession.shared.dataTask(with: request as URLRequest)
{(data,response,error) -> Void in
if error != nil
{
print(error?.localizedDescription as Any)
return
}
do
{
let json = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
print(json)
}
catch let error as NSError
{
print(error.localizedDescription)
}
}
task.resume()
I have also tried request.setValue("Bearer " + key, forHTTPHeaderField: "Authorization")
Try this :
var sessionConfig = URLSessionConfiguration.default
var authValue: String? = "Bearer \(key)"
sessionConfig.httpAdditionalHeaders = ["Authorization": authValue ?? <#default value#>]
var session = URLSession(configuration: sessionConfig, delegate: self as? URLSessionDelegate, delegateQueue: nil)
The following below code is of hitting web service in swift by using NSURLSession .. I always get authentication failed message from server.Not able to get what is missing in request body.
let urlString:String = "\(BaseURL)"+"user_register.php?"
let deviceStr = "xyz"
let dictParam:NSDictionary = ["email":"\((emailTF?.text!)!)","username":"\((usernameTF?.text!)!)","password":"\((passwordTF?.text!)!)","device_key":deviceStr]
print(dictParam)
let session = NSURLSession.sharedSession()
let request = NSMutableURLRequest(URL: NSURL(string: urlString)!)
request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringCacheData
request.timeoutInterval = 60.0
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
// request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPMethod = "POST"
let dataToPost = try! NSJSONSerialization.dataWithJSONObject(dictParam, options: [])
request.HTTPBody = dataToPost
let task = session.dataTaskWithRequest(request) {
(
let data, let response, let error) in
guard let _:NSData = data, let _:NSURLResponse = response where error == nil else {
print("error")
return
}
let response:AnyObject! = try! NSJSONSerialization.JSONObjectWithData(data!, options: [])
print(data!)
print(response)
}
task.resume()
This question already has an answer here:
Fixing NSURLConnection Deprecation from Swift 1.2 to 2.0
(1 answer)
Closed 7 years ago.
Xcode says that sendSynchronousRequest is now deprecated.
How should I replace it?
let postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)!
let postLength:NSString = String( postData.length )
let request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.HTTPBody = postData
request.setValue(postLength as String, forHTTPHeaderField: "Content-Length")
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
var response: NSURLResponse?
var urlData: NSData?
do {
urlData = try NSURLConnection.sendSynchronousRequest(request, returningResponse:&response)
} catch _ as NSError {
urlData = nil
} catch {
fatalError()
}
This is a working example,
You should use NSURLSession, with Request.
func testPost(sender: UIButton) {
let session = NSURLSession.sharedSession()
let request = NSMutableURLRequest(URL: NSURL(string: "http://localhost:8080/iOSServer/ios/helloworld/swiftCalculator")!)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.HTTPMethod = "POST"
let d = "4"
let data = "x=4&y=\(d)"
request.HTTPBody = data.dataUsingEncoding(NSASCIIStringEncoding)
let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
if let error = error {
print(error)
}
if let data = data{
print("data =\(data)")
}
if let response = response {
print("url = \(response.URL!)")
print("response = \(response)")
let httpResponse = response as! NSHTTPURLResponse
print("response code = \(httpResponse.statusCode)")
//if you response is json do the following
do{
let resultJSON = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions())
let arrayJSON = resultJSON as! NSArray
for value in arrayJSON{
let dicValue = value as! NSDictionary
for (key, value) in dicValue {
print("key = \(key)")
print("value = \(value)")
}
}
}catch _{
print("Received not-well-formatted JSON")
}
}
})
task.resume()
}
Notice it is not necessary to use the request. you can have a data task with URL, but I added the request because in your code, you have set some headers in the request.
Notice using the completionHandler which will be called when your server responses by http response.
I am new in swift language. I looked at some questions for parsing Json in swift in here but my issue is alittle different from others.
when i write /cmd=login¶ms{'user':'username','password':'pass'} it returns correct data. how to resolve this in swift
I send username and password to url as json but
it retrieve error which means "invalid format "
Please help me.
Here is what i have tried:
var url:NSURL = NSURL(string: "http://<host>?cmd=login")!
//var session = NSURLSession.sharedSession()
var responseError: NSError?
var request = NSMutableURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
// var request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
var response: NSURLResponse?
request.HTTPMethod = "POST"
let jsonString = "params={\"user\":\"username\",\"password\":\"pass\"}"
request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion:true)
request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
// send the request
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &responseError)
// look at the response
if let httpResponse = response as? NSHTTPURLResponse {
println("HTTP response: \(httpResponse.statusCode)")
} else {
println("No HTTP response")
}
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){
data, response, error in
if error != nil {
println("error=\(error)")
return
}
println("****response= \(response)")
let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
println("**** response =\(responseString)")
var err: NSError?
var json = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers , error: &err) as? NSDictionary
}
task.resume()
Assuming based on your question that the format the server is expecting is something like this:
http://<host>?cmd=login¶ms=<JSON object>
You would need to first URL-encode the JSON object before appending it to the query string to eliminate any illegal characters.
You can do something like this:
let jsonString = "{\"user\":\"username\",\"password\":\"pass\"}"
let urlEncoadedJson = jsonString.stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())
let url = NSURL(string:"http://<host>?cmd=login¶ms=\(urlEncoadedJson)")
Let's say url is
https://example.com/example.php?Name=abc&data={"class":"625","subject":"english"}
in Swift 4
let abc = "abc"
let class = "625"
let subject = "english"
let baseurl = "https://example.com/example.php?"
let myurlwithparams = "Name=\(abc)" + "&data=" +
"{\"class\":\"\(class)\",\"subject\":\"\(subject)\"}"
let encoded =
myurlwithparams.addingPercentEncoding(withAllowedCharacters:
.urlFragmentAllowed)
let encodedurl = URL(string: encoded!)
var request = URLRequest(url: encodedurl!)
request.httpMethod = "GET"
I don't think you need to encode your JSON the way you're doing it. Below should work.
let jsonString = "params={\"user\":\"username\",\"password\":\"pass\"}"
var url:NSURL = NSURL(string: "http://<host>?cmd=login&?\(jsonString)")!
//var session = NSURLSession.sharedSession()
var responseError: NSError?
var request = NSMutableURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
// var request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
var response: NSURLResponse?
request.HTTPMethod = "POST"
You json string is not valid, it should be like:
let jsonString = "{\"user\":\"username\",\"password\":\"pass\"}"
As for the request, I think GET it what you really need:
var urlString = "http://<host>" // Only the host
let payload = "?cmd=login¶ms=" + jsonString // params goes here
urlString += payload
var url:NSURL = NSURL(string: urlString)!
// ...
request.HTTPMethod = "GET"
I'm (trying to) learn the Swift's Apple language. I'm at Playground and using Xcode 6 Beta. I'm trying to do a simple JSON Post to a local NodeJS server. I already had googled about it and the major tutorials explain how to do it in a project, not at PLAYGROUND, than don't write stupid thinks like: "google it" or "it's obvious" or "look this link" or never-tested-and-not-functional-code
This is what i'm trying:
var request = NSURLRequest(URL: NSURL(string: "http://localhost:3000"), cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response : NSURLResponse?
var error : NSError?
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
I had tried:
var dataString = "some data"
var request = NSMutableURLRequest(URL: NSURL(string: "http://posttestserver.com/post.php"))
request.HTTPMethod = "POST"
let data = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
var requestBodyData: NSData = data
request.HTTPBody = requestBodyData
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: false)
println("sending request...")
connection.start()
Thank you! :)
Nate's answer was great but I had to change the request.setvalue for it to work on my server
// create the request & response
var request = NSMutableURLRequest(URL: NSURL(string: "http://requestb.in/1ema2pl1"), cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response: NSURLResponse?
var error: NSError?
// create some JSON data and configure the request
let jsonString = "json=[{\"str\":\"Hello\",\"num\":1},{\"str\":\"Goodbye\",\"num\":99}]"
request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
// send the request
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
// look at the response
if let httpResponse = response as? NSHTTPURLResponse {
println("HTTP response: \(httpResponse.statusCode)")
} else {
println("No HTTP response")
}
It looks like you have all the right pieces, just not in quite the right order:
// create the request & response
var request = NSMutableURLRequest(URL: NSURL(string: "http://requestb.in/1ema2pl1"), cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response: NSURLResponse?
var error: NSError?
// create some JSON data and configure the request
let jsonString = "json=[{\"str\":\"Hello\",\"num\":1},{\"str\":\"Goodbye\",\"num\":99}]"
request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
// send the request
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
// look at the response
if let httpResponse = response as? NSHTTPURLResponse {
println("HTTP response: \(httpResponse.statusCode)")
} else {
println("No HTTP response")
}
Here is a little different approach using asynchronous request. You can use synchronous approach this way too but since everyone above used synchronous request, I thought show asynchronous request instead. Another thing is it seems cleaner and easier this way.
let JSONObject: [String : AnyObject] = [
"name" : name,
"address" : address,
"phone": phoneNumber
]
if NSJSONSerialization.isValidJSONObject(JSONObject) {
var request: NSMutableURLRequest = NSMutableURLRequest()
let url = "http://tendinsights.com/user"
var err: NSError?
request.URL = NSURL(string: url)
request.HTTPMethod = "POST"
request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(JSONObject, options: NSJSONWritingOptions(rawValue:0), error: &err)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue()) {(response, data, error) -> Void in
if error != nil {
println("error")
} else {
println(response)
}
}
}
