I am using trying to post some data to server using Swift URLRequest with using following code.
var request = URLRequest(url: URL(string: Global.ip)!)
request.httpMethod = "POST"
request.addValue("application/x-www-form-urlencoded; charset=UTF-8", forHTTPHeaderField: "Content-Type")
let postString = "cmd=getFavorites" + "&ab={\"userId\":\"\(userId)\",\"favId\":\"\(favoriteId)\",\"favoriData\":\(panelData)}&token=\(token)"
let newPostString = postString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)
request.httpBody = newPostString?.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print("error=\(String(describing: error))")
completion(false)
return;
}
let json = JSON(data)
completion(true)
}
task.resume()

How to pass HTTPBody like this content type in urlrequest
below is the code which i tried from postman code -
var semaphore = DispatchSemaphore (value: 0)
let parameters = "code=httagtsgdgtdfsg&client_secret=agsfstf&Grant_type=authorization_code"
let postData = parameters.data(using: .utf8)
var request = URLRequest(url: URL(string: "url")!,timeoutInterval: Double.infinity)
request.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "HTTPMethod"
request.httpBody = postData
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data else {
print(String(describing: error))
return
}
print(String(data: data, encoding: .utf8)!)
semaphore.signal()
}
task.resume()
semaphore.wait()
What's this?
request.httpMethod = "HTTPMethod"
It should be
request.httpMethod = "POST"
I have a request in Swift 5 that is trying to make a call to tinify.com. It is supposed to give me back a URL to a compressed image. I am currently getting this error in the print field:
{"error":"Not found","message":"This endpoint does not exist."}
TinyPNG.com API Reference
Code:
let string = "https://api.tinify.com/shrink"
let url = NSURL(string: string)
let request = NSMutableURLRequest(url: url! as URL)
request.httpMethod = "GET"
request.addValue("fakeAPIKey1234", forHTTPHeaderField: "user api")
request.addValue("/dev/stdout", forHTTPHeaderField: "dump-header")
request.addValue("\(String(describing: self.jpegData(compressionQuality: 0.8)!))", forHTTPHeaderField: "data-binary")
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) -> Void in
guard error == nil else { print(error!.localizedDescription); return }
guard let data = data else { print("Empty data"); return }
if let str = String(data: data, encoding: .utf8) {
print("Grab Image from this url: \(str)")
}
}
Note: fakeAPIKey1234 is not actually the string I'm using. Also I'm sure there is more wrong with my code than this little issue.
im new at swift and im trying to get response from a soap services, but the dataTask in my session never get in, always skip it. I already test te urls and the soap message but i don't have any lucky. Here is my code
func servisRun(){
let soapMessage = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\"><soapenv:Header/><soapenv:Body><tem:LogIn><tem:user>00002403</tem:user><tem:password>123456</tem:password></tem:LogIn></soapenv:Body></soapenv:Envelope>"
let msgLength = String(describing: soapMessage.characters.count)
let url = URL(string: "http://192.168.1.171/WcfSif.Services.Login.Login.svc")
var request = URLRequest(url: url!)
request.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.addValue(msgLength, forHTTPHeaderField: "Content-Length")
request.httpMethod = "POST"
request.httpBody = soapMessage.data(using: String.Encoding.utf8, allowLossyConversion: false)
URLSession.shared.dataTask(with: request) { (data, resp, error) in
guard error == nil && data != nil else{
print("connection error or data is nill")
return
}
if resp != nil {
self.mutableData?.length = 0;
}
let mutableData : Void = NSMutableData.initialize()
print(mutableData)
let dataString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
self.mutableData?.append(data!)
print(dataString!)
}
.resume()
let nsData = mutableData?.copy() as! NSData
let xmlParser = XMLParser(data: nsData as Data)
xmlParser.delegate = self
xmlParser.parse()
xmlParser.shouldResolveExternalEntities = true
}
I want to access the magenta REST API in my iOS application.
Following is my code to access the API:
func getCustomerTokenusingURLSEssion(){
let url = URL(string: "HTTPURL")!
var urlRequest = URLRequest(
url: url,
cachePolicy: .reloadIgnoringLocalAndRemoteCacheData,
timeoutInterval: 10.0 * 1000)
urlRequest.httpMethod = "POST"
urlRequest.addValue("application/json", forHTTPHeaderField: "Accept")
let json1: [String: Any] = [
"username": "xyz#gmail.com",
"password":"xyz12345"]
let jsonData = try? JSONSerialization.data(withJSONObject: json1, options: .prettyPrinted)
urlRequest.httpBody = jsonData
let config = URLSessionConfiguration.default
let urlsession = URLSession(configuration: config)
let task = urlsession.dataTask(with: urlRequest){ (data, response, error) -> Void in
print("response from server: \(response)")
guard error == nil else {
print("Error while fetching remote rooms: \(error)")
return
}
guard let data = data,
let json = try? JSONSerialization.jsonObject(with: data) as? [String: Any] else {
print("Nil data received from fetchAllRooms service ")
return
}
print("JSON \(json)")
}
task.resume()
}
But I'm getting error message form the server as follow:
["message": Server cannot understand Content-Type HTTP header media type application/x-www-form-urlencoded]
Please help!
Thanks!
Here's working example of token-based authentication from iOS to magento2 using swift:
func restApiAuthorize(completionBlock: #escaping (String) -> Void) {
// Prepare json data
let json: [String: Any] = ["username": “yourusername”,
"password": “yourpassowrd”]
let jsonData = try? JSONSerialization.data(withJSONObject: json)
// Create post request
let url = URL(string: "http://yourmagentodomain.com/index.php/rest/V1/integration/customer/token")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("\(jsonData!.count)", forHTTPHeaderField: "Content-Length")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
// Insert json data to the request
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
// 1: Check HTTP Response for successful GET request
guard let httpResponse = response as? HTTPURLResponse
else {
print("error: not a valid http response")
return
}
print(httpResponse.statusCode)
switch (httpResponse.statusCode)
{
case 200:
let responseData = String(data: data, encoding: String.Encoding.utf8)!
print ("responseData: \(responseData)")
completionBlock(responseData)
default:
print("POST request got response \(httpResponse.statusCode)")
}
}
task.resume()
}
And usage is like that:
restApiAuthorize() { (output) in
// token data, I found it important to remove quotes otherwise token contains extra quotes in the end and beginning of string
let userToken = output.replacingOccurrences(of: "\"", with: "")
print ("userToken \(userToken)")
}
you can then write your userToken to userDefaults and make feature api calls.
Best Guest you forgot to set your Content-Type, so add this:
urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
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.
