Swift 4 - When sending POST request to localhost, my URLRequest sends the JSON data with the dictionary as a key - ios

Seems like a simple error, but I cannot resolve it for some reason:
let parameters = ["user_id":usernameTF.text!, "password": passwordTF.text!]
let jsonData = try? JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted)
print(parameters)
print(jsonData!)
var request = URLRequest(url: url)
request.setValue("application/json", forHTTPHeaderField:"Accept")
request.httpMethod = "POST"
debugTV.text = "\(parameters["user_id"]!)"+"\(parameters["password"]!)"
do {
request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options:[])
// pass dictionary to nsdata object and set it as request body
print(request.httpBody!)
} catch let error {
print(error.localizedDescription)
}
let task = session.dataTask(with: request) { (data, response, error) in
guard error == nil else {
return
}
guard let data = data else {
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {
// check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
}
let responseString = String(data: data, encoding: .utf8)
print(responseString!)
}
when see the NodeJS debug window, my request body is
req.body = { '[password: "test", user_id: "test"]':'' }
how can I convert the request data into a JSON object?

Swift make a http request response as array

I have got this swift http request
var request = URLRequest(url: URL(string: "http://www.web.com/ajax/logreg.php")!)
request.httpMethod = "POST"
let pass = pass_text_field.text!.addingPercentEncoding(withAllowedCharacters: .queryValueAllowed)!
let postString = "app_reg_pass=\(pass)"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print("error=\(error!)")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { print("statusCode should be 200, but is \(httpStatus.statusCode)")
print(response!)
}
let responseString = String(data: data, encoding: .utf8)
print(responseString!)
}
task.resume()
Reponse string:
Array
(
[0] => 1
[1] => Murad
)
And my response to this code is array.But when i try to treat response as array it gives me an error.How can i turn response into array so i can do this
response[0]?
Your result is most likely coming in as a JSON object, so you need to deserialize it before you can use the results.
do {
let jsonData = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [Any]
print(jsonData[0] as! Int) // should print "1"
print(jsonData[1] as! String) // should print "Murad"
} catch {
print("An error occurred")
}

I'm trying send username and password for getting authentication code from server how can send array of parameter instead of one parameter?
Try this I hope it would be helpful for you!!

var session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
var params = ["UserName":"UserName you wish to send", "password":"Password you wish to send"] as Dictionary<String, String>
var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)
var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
print("Response: \(response)")`

swift ios mobile app login submit

I'm trying to program an iOS application for this website of our university: https://uniworx.ifi.lmu.de/
I failed with the login. I have managed it to send a http submit for the login form, but I always get the same site back as response. I want to get the site you normally see after logging in. What am I doing wrong?
Here is the code of my function:
func newTest()
{
let request = NSMutableURLRequest(url: NSURL(string: "http://uniworx.ifi.lmu.de/?action=uniworxLoginDo")! as URL)
request.httpMethod = "POST"
let postString = "username=myusername&password=mypassword"
request.httpBody = postString.data(using: String.Encoding.utf8)
let task = URLSession.shared.dataTask(with: request as URLRequest) { data, response, error in
guard error == nil && data != nil else {
print("error=\(error)")
return
}
if let httpStatus = response as? HTTPURLResponse , httpStatus.statusCode != 200 {
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(response)")
}
let responseString = String(data: data!, encoding: String.Encoding.utf8)
print("responseString = \(responseString)")
}
task.resume()
}
I've changed my real username and password in the code -of course-.
Try this I hope it would be helpful for you!!
In Swift 2+
let request = NSMutableURLRequest(URL: NSURL(string: "http://uniworx.ifi.lmu.de/?action=uniworxLoginDo")!)
request.HTTPMethod = "POST"
let postString = "Username=Yourusername&password=Yourpassword"
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in
guard error == nil && data != nil else { // check for fundamental networking error
print("error=\(error)")
return
}
if let httpStatus = response as? NSHTTPURLResponse where 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: NSUTF8StringEncoding)
print("responseString = \(responseString)")
}
task.resume()
In Swift 3 You can
var request = URLRequest(url: URL(string: "http://uniworx.ifi.lmu.de/?action=uniworxLoginDo")!)
request.httpMethod = "POST"
let postString = "Username=Yourusername&password=Yourpassword"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else { // check for fundamental networking error
print("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)")

HTTP Request in Swift with POST method

I'm trying to run a HTTP Request in Swift, to POST 2 parameters to a URL.
Example:
Link: www.thisismylink.com/postName.php
Params:
id = 13
name = Jack
What is the simplest way to do that?
I don't even want to read the response. I just want to send that to perform changes on my database through a PHP file.
The key is that you want to:
set the httpMethod to POST;
optionally, set the Content-Type header, to specify how the request body was encoded, in case server might accept different types of requests;
optionally, set the Accept header, to request how the response body should be encoded, in case the server might generate different types of responses; and
set the httpBody to be properly encoded for the specific Content-Type; e.g. if application/x-www-form-urlencoded request, we need to percent-encode the body of the request.
E.g., in Swift 3 and later you can:
let url = URL(string: "https://httpbin.org/post")!
var request = URLRequest(url: url)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
request.httpMethod = "POST"
let parameters: [String: Any] = [
"id": 13,
"name": "Jack & Jill"
]
request.httpBody = parameters.percentEncoded()
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard
let data = data,
let response = response as? HTTPURLResponse,
error == nil
else { // check for fundamental networking error
print("error", error ?? URLError(.badServerResponse))
return
}
guard (200 ... 299) ~= response.statusCode else { // check for http errors
print("statusCode should be 2xx, but is \(response.statusCode)")
print("response = \(response)")
return
}
// do whatever you want with the `data`, e.g.:
do {
let responseObject = try JSONDecoder().decode(ResponseObject<Foo>.self, from: data)
print(responseObject)
} catch {
print(error) // parsing error
if let responseString = String(data: data, encoding: .utf8) {
print("responseString = \(responseString)")
} else {
print("unable to parse response as string")
}
}
}
task.resume()
Where the following extensions facilitate the percent-encoding request body, converting a Swift Dictionary to a application/x-www-form-urlencoded formatted Data:
extension Dictionary {
func percentEncoded() -> Data? {
map { key, value in
let escapedKey = "\(key)".addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed) ?? ""
let escapedValue = "\(value)".addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed) ?? ""
return escapedKey + "=" + escapedValue
}
.joined(separator: "&")
.data(using: .utf8)
}
}
extension CharacterSet {
static let urlQueryValueAllowed: CharacterSet = {
let generalDelimitersToEncode = ":#[]#" // does not include "?" or "/" due to RFC 3986 - Section 3.4
let subDelimitersToEncode = "!$&'()*+,;="
var allowed: CharacterSet = .urlQueryAllowed
allowed.remove(charactersIn: "\(generalDelimitersToEncode)\(subDelimitersToEncode)")
return allowed
}()
}
And the following Decodable model objects facilitate the parsing of the application/json response using JSONDecoder:
// sample Decodable objects for https://httpbin.org
struct ResponseObject<T: Decodable>: Decodable {
let form: T // often the top level key is `data`, but in the case of https://httpbin.org, it echos the submission under the key `form`
}
struct Foo: Decodable {
let id: String
let name: String
}
This checks for both fundamental networking errors as well as high-level HTTP errors. This also properly percent escapes the parameters of the query.
Note, I used a name of Jack & Jill, to illustrate the proper x-www-form-urlencoded result of name=Jack%20%26%20Jill, which is “percent encoded” (i.e. the space is replaced with %20 and the & in the value is replaced with %26).
See previous revision of this answer for Swift 2 rendition.
Swift 4 and above
func postRequest() {
// declare the parameter as a dictionary that contains string as key and value combination. considering inputs are valid
let parameters: [String: Any] = ["id": 13, "name": "jack"]
// create the url with URL
let url = URL(string: "www.thisismylink.com/postName.php")! // change server url accordingly
// create the session object
let session = URLSession.shared
// now create the URLRequest object using the url object
var request = URLRequest(url: url)
request.httpMethod = "POST" //set http method as POST
// add headers for the request
request.addValue("application/json", forHTTPHeaderField: "Content-Type") // change as per server requirements
request.addValue("application/json", forHTTPHeaderField: "Accept")
do {
// convert parameters to Data and assign dictionary to httpBody of request
request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted)
} catch let error {
print(error.localizedDescription)
return
}
// create dataTask using the session object to send data to the server
let task = session.dataTask(with: request) { data, response, error in
if let error = error {
print("Post Request Error: \(error.localizedDescription)")
return
}
// ensure there is valid response code returned from this HTTP response
guard let httpResponse = response as? HTTPURLResponse,
(200...299).contains(httpResponse.statusCode)
else {
print("Invalid Response received from the server")
return
}
// ensure there is data returned
guard let responseData = data else {
print("nil Data received from the server")
return
}
do {
// create json object from data or use JSONDecoder to convert to Model stuct
if let jsonResponse = try JSONSerialization.jsonObject(with: responseData, options: .mutableContainers) as? [String: Any] {
print(jsonResponse)
// handle json response
} else {
print("data maybe corrupted or in wrong format")
throw URLError(.badServerResponse)
}
} catch let error {
print(error.localizedDescription)
}
}
// perform the task
task.resume()
}
For anyone looking for a clean way to encode a POST request in Swift 5.
You don’t need to deal with manually adding percent encoding.
Use URLComponents to create a GET request URL. Then use query property of that URL to get properly percent escaped query string.
let url = URL(string: "https://example.com")!
var components = URLComponents(url: url, resolvingAgainstBaseURL: false)!
components.queryItems = [
URLQueryItem(name: "key1", value: "NeedToEscape=And&"),
URLQueryItem(name: "key2", value: "vålüé")
]
let query = components.url!.query
The query will be a properly escaped string:
key1=NeedToEscape%3DAnd%26&key2=v%C3%A5l%C3%BC%C3%A9
Now you can create a request and use the query as HTTPBody:
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = Data(query.utf8)
Now you can send the request.
Heres the method I used in my logging library: https://github.com/goktugyil/QorumLogs
This method fills html forms inside Google Forms.
var url = NSURL(string: urlstring)
var request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)
let session = URLSession.shared
let url = "http://...."
let request = NSMutableURLRequest(url: NSURL(string: url)! as URL)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
var params :[String: Any]?
params = ["Some_ID" : "111", "REQUEST" : "SOME_API_NAME"]
do{
request.httpBody = try JSONSerialization.data(withJSONObject: params, options: JSONSerialization.WritingOptions())
let task = session.dataTask(with: request as URLRequest as URLRequest, completionHandler: {(data, response, error) in
if let response = response {
let nsHTTPResponse = response as! HTTPURLResponse
let statusCode = nsHTTPResponse.statusCode
print ("status code = \(statusCode)")
}
if let error = error {
print ("\(error)")
}
if let data = data {
do{
let jsonResponse = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions())
print ("data = \(jsonResponse)")
}catch _ {
print ("OOps not good JSON formatted response")
}
}
})
task.resume()
}catch _ {
print ("Oops something happened buddy")
}
All the answers here use JSON objects. This gave us problems with the
$this->input->post()
methods of our Codeigniter controllers. The CI_Controller cannot read JSON directly.
We used this method to do it WITHOUT JSON
func postRequest() {
// Create url object
guard let url = URL(string: yourURL) else {return}
// Create the session object
let session = URLSession.shared
// Create the URLRequest object using the url object
var request = URLRequest(url: url)
// Set the request method. Important Do not set any other headers, like Content-Type
request.httpMethod = "POST" //set http method as POST
// Set parameters here. Replace with your own.
let postData = "param1_id=param1_value&param2_id=param2_value".data(using: .utf8)
request.httpBody = postData
// Create a task using the session object, to run and return completion handler
let webTask = session.dataTask(with: request, completionHandler: {data, response, error in
guard error == nil else {
print(error?.localizedDescription ?? "Response Error")
return
}
guard let serverData = data else {
print("server data error")
return
}
do {
if let requestJson = try JSONSerialization.jsonObject(with: serverData, options: .mutableContainers) as? [String: Any]{
print("Response: \(requestJson)")
}
} catch let responseError {
print("Serialisation in error in creating response body: \(responseError.localizedDescription)")
let message = String(bytes: serverData, encoding: .ascii)
print(message as Any)
}
// Run the task
webTask.resume()
}
Now your CI_Controller will be able to get param1 and param2 using $this->input->post('param1') and $this->input->post('param2')
#IBAction func btn_LogIn(sender: AnyObject) {
let request = NSMutableURLRequest(URL: NSURL(string: "http://demo.hackerkernel.com/ios_api/login.php")!)
request.HTTPMethod = "POST"
let postString = "email: test#test.com & password: testtest"
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){data, response, error in
guard error == nil && data != nil else{
print("error")
return
}
if let httpStatus = response as? NSHTTPURLResponse where httpStatus.statusCode != 200{
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(response)")
}
let responseString = String(data: data!, encoding: NSUTF8StringEncoding)
print("responseString = \(responseString)")
}
task.resume()
}
