I'm trying to make an API call here using a post method, however I keep getting
[[boringssl] boringssl_metrics_log_metric_block_invoke(144)]
and the data returned is an empty object {"finalResults":[]}.
Tested the API using postman and the data returns safely.
This is my code:
var dict = Dictionary<String, String>()
dict = [
"queryText": query,
"lat": "31.206865038834433",
"long": "29.965068562105422",
"pageToken": "",
]
let url:URL = URL(string: apiEndPointURLString)!
let session = URLSession.shared
var postData = NSData()
do{
postData = try JSONSerialization.data(withJSONObject: dict, options: JSONSerialization.WritingOptions.prettyPrinted) as NSData
}catch {
print("error serializing.......\n\n\n\n")
}
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("\(postData.length)", forHTTPHeaderField: "Content-Length")
request.setValue("text/html", forHTTPHeaderField: "Content-Type")
request.setValue("json/application", forHTTPHeaderField: "Accept")
request.httpBody = postData as Data
let task = session.dataTask(with: request as URLRequest) {
(
data, response, error) in
guard let data = data, let _:URLResponse = response, error == nil else {
print("error")
return
}
let dataString = String(data: data, encoding: String.Encoding.utf8)
print(dataString ?? "no data")
}
task.resume()

I'm trying to do this post request and I'm getting success as result but user data Full Name, Gender, and DOB are not updating on the server, all are set to null. I think data that I passed is not going to the server properly. Here is my code:
func syncPostRequst() -> Bool {
let plist = PlistHelper()
var tokenString = plist.getAnyValueFromPlistFile("ACCESS_TOKEN")
//create the url with URL
let url = URL(string: "http://192.168.1.3:8080/api/User/UpdateBasicUserDetails")! //change the url
//create the session object
let session = URLSession.shared
let json: [String: Any] = ["DateOfBirth": "2010.3.3", "FullName": "Anushka Edited iOS", "Gender":"Male"]
let jsonData = try? JSONSerialization.data(withJSONObject: json)
NSLog("JDATASE: \(jsonData)")
NSLog("JDATASEQQQ: \(JSON(jsonData))")
//now create the URLRequest object using the url object
var request = URLRequest(url: url)
request.httpMethod = "POST" //set http method as POST
// insert json data to the request
request.httpBody = jsonData
request.addValue("Bearer \(tokenString)", forHTTPHeaderField: "Authorization")
request.addValue("application/json", forHTTPHeaderField: "Accept")
//create dataTask using the session object to send data to the server
let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in
print("json222:::\(JSON(data!))")
NSLog("request9900: \(request)")
guard error == nil else {
return
}
guard let data = data else {
return
}
do {
//create json object from data
if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
print("json:::\(json)")
// handle json...
}
} catch let error {
print("ERRROR Caught: \(error.localizedDescription)")
}
})
task.resume()
return true
}
I'm using Swift 3.0, Does anyone knows any reason for this?
I am trying to receive and process a POST request being sent from my iOS app to my Node.js web server. The server responds with HTTP Error 502 whenever I try to send this POST request. Could you please look at my code below and see what is wrong with it? Thank you!
Node.js Code
app.post('/applogin', function(req, res) {
var parsedBody = JSON.parse(req.body);
console.log(parsedBody)
});
Swift Code (POST function)
func httpPost(jsonData: Data) {
if !jsonData.isEmpty {
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = jsonData
URLSession.shared.getAllTasks { (openTasks: [URLSessionTask]) in
NSLog("open tasks: \(openTasks)")
}
let task = URLSession.shared.dataTask(with: request, completionHandler: { (responseData: Data?, response: URLResponse?, error: Error?) in
NSLog("\(response)")
})
task.resume()
}
}
Swift Code (sending of the POST request)
#IBAction func onClick(_ sender: Any) {
let username = Username.text
let password = Password.text
var dataString = "username: \(username), password: \(password)"
let data = dataString.data(using: .utf8)
httpPost(jsonData: data!)
}
Thanks in advance!
You have to send a json instead dataString, and you have to set the "Content Type" header with value "application/json"
Swift 2
let request = NSMutableURLRequest(URL: requestUrl)
request.HTTPMethod = "POST"
let params = ["username" : username, "password" : password] as Dictionary<String, AnyObject>
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options:NSJSONWritingOptions.PrettyPrinted)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
Many answers they don't mention that we need to set header for the request from Swift side before sending to the backend otherwise it'll be a string in a wrong format that we can't use JSON.parse, here's what I firgured out (NOTE the IMPORTANT line):
let json = [
"email": emailTextField.text
]
let jsonData = try! JSONSerialization.data(withJSONObject: json)
let url = URL(string: BASE_URL + "/auth/register")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
// insert json data to the request
request.httpBody = jsonData
//IMPORTANT
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
if let responseJSON = responseJSON as? [String: Any] {
print(responseJSON)
}
}
task.resume()
And in your NodeJS with Express just call req.body and you're done
Try this:
app.post('/applogin', function(req, res) {
var parsedBody = JSON.parse(req.body);
console.log(parsedBody)
res.send("Request received")
});
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")
I want to send dictionary data to server but server's POST response is showing blank.
func HitApi(callback: (NSDictionary) -> Void){
let mapDict = [ "1":"First", "2":"Second"]
let json = [ "title":"ABC" , "dict": mapDict ]
let jsonData:NSData?
do {
jsonData = try NSJSONSerialization.dataWithJSONObject(json, options: .PrettyPrinted)
}catch{
jsonData = nil
}
// create post request
let url = NSURL(string: "http://myserver.com")!
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Accept")
request.HTTPBody = jsonData
var dict = ["output":""]
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data,response,error in
if error != nil{
dict["output"] = "An error"
callback(dict)
}
do {
let data = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments) as? NSDictionary
dict["output"] = NSString(data: data!, encoding: NSUTF8StringEncoding)
callback(dict)
}catch{
dict["output"] = "error"
callback(dict)
}
}
task.resume()
}
If I use this code, then everything is going fine:
func HitApi(callback: (NSDictionary) -> Void){
let dataToSend:String = "1=First&2=Second"
let jsonData:NSData?
// create post request
let url = NSURL(string: "http://myserver.com")!
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Accept")
request.HTTPBody = dataToSend.dataUsingEncoding(NSUTF8StringEncoding)
var dict = ["output":""]
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data,response,error in
if error != nil{
dict["output"] = "An error"
callback(dict)
}
do {
let data = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments) as? NSDictionary
dict["output"] = NSString(data: data!, encoding: NSUTF8StringEncoding)
callback(dict)
}catch{
dict["output"] = "error"
callback(dict)
}
}
task.resume()
}
Now server is responding fine. But if i have big nested dictionary data then this method will be fail. What is problem in my first code?
Sending this code with HTTP POST returns an ID, but I'm so far unable to extract the ID from responseString and save it as it's own String in my app.
I'm looking into using Alamofire, perhaps that'll make things easier but I was hoping to be able to do it using just Swift code. Any help is appreciated.
var parseError: NSError?
let date = NSDate()
let timeStamp = date.timeIntervalSince1970
var request = NSMutableURLRequest(URL: NSURL(string: URL)!)
request.HTTPMethod = "POST"
let params = ["name":fullName.text, "number":phoneNumber.text, "email":emailAddress.text, "timeStarted":timeStamp] as Dictionary<String, AnyObject>
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: nil)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
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("responseString = \(responseString)")
let idFromServer = responseString?.valueForKeyPath("id") as String!
println(idFromServer)
var dateID = idFromServer
newUser.setValue(dateID, forKey: "dateID")
