I'm trying to access to a dictionary API by the following code:
func apiConnection() {
if let url = NSURL(string:"https://wordsapiv1.p.mashape.com/words/soliloquy") {
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
request.addValue("aaabbbccc", forHTTPHeaderField: "X-Mashape-Key")
request.addValue("application/json", forHTTPHeaderField: "Accept")
print(request.HTTPBody)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil {
print("\(error)")
return
}
print("\(response)")
let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("\(responseString)")
}
}
}
Was I doing something wrong with the code? Sorry i'm pretty new in this area. The API I used is from https://market.mashape.com/wordsapi/wordsapi
You configured the task, but didn't start it
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
...
}
task.resume() // Start the task

I have an odd issue and I am hoping you guys can help me.
The Task:
I want to post json to a API rest call.
And I am sure the rest API works - I have copied the json from print() in Swift and tried it in postman, and the works just fine.
When I try to post via Swift i get 400 Bad request.
The code:
func postMobileContacts(serverURL: String, jsonToPost: String){
// Prepare URL
let url = URL(string: serverURL)
guard let requestUrl = url else { fatalError() }
// Prepare URL Request Object
var request = URLRequest(url: requestUrl)
request.httpMethod = "POST"
// Set HTTP Request Body
request.httpBody = Data(jsonToPost.utf8);
// Set HTTP Request Header
request.setValue("application/json", forHTTPHeaderField: "Accept")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("Authorization", forHTTPHeaderField: String(data: KeychainHelper.standard.read(service: "access-token", account: "store")!, encoding: .utf8)!)
// Perform HTTP Request
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
// Check for Error
if let error = error {
print("Error took place \(error)")
return
}
// Convert HTTP Response Data to a String
if let data = data, let dataString = String(data: data, encoding: .utf8) {
print("Response data string:\n \(dataString)")
}
}
task.resume()
}
This line is definitely wrong:
request.setValue("Authorization", forHTTPHeaderField: String(data: KeychainHelper.standard.read(service: "access-token", account: "store")!, encoding: .utf8)!)
it should be the other way around.
request.setValue(String(data: KeychainHelper.standard.read(service: "access-token", account: "store")!, encoding: .utf8)!, forHTTPHeaderField: "Authorization")
You mixed up the value with the header name.
Made some edits to your code
Currently the data is not directly sent to the request as said in comments.
JSONEncodable can be send to the request after encoding to data.
func postMobileContacts(serverURL: String, jsonToPost: Encodable) { //<--here
// Prepare URL
let url = URL(string: serverURL)
guard let requestUrl = url else { fatalError() }
let data = try! JSONEncoder().encode(jsonToPost) //<-Changed here
// Prepare URL Request Object
var request = URLRequest(url: requestUrl)
request.httpMethod = "POST"
// Set HTTP Request Body
request.httpBody = data; //<-- and here
// Set HTTP Request Header
request.setValue("application/json", forHTTPHeaderField: "Accept")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("Authorization", forHTTPHeaderField: String(data: KeychainHelper.standard.read(service: "access-token", account: "store")!, encoding: .utf8)!)
// Perform HTTP Request
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
// Check for Error
if let error = error {
print("Error took place \(error)")
return
}
// Convert HTTP Response Data to a String
if let data = data, let dataString = String(data: data, encoding: .utf8) {
print("Response data string:\n \(dataString)")
}
}
task.resume()
}
okay, so Im trying to make a post request but when I try to parse the data, I always get a error domain code= 3840.
https://www.codepunker.com/tools/http-requests/64243-brrjq9t
In this example it shows what the request response looks like.
and this is my code:
let parameters = ["txt": "כאב גרון","usr": "","pass": "" ,"ktivmale": false] as [String : Any]
guard let url = URL(string: "http://www.nakdan.com/GetResult.aspx") else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else { return }
request.httpBody = httpBody
let task = URLSession.shared.dataTask(with: request as URLRequest){
data,response, error in
print(response!)
if error != nil{
print("error")
return
}
do {
let json = try JSONSerialization.jsonObject(with: data!, options: [])
DispatchQueue.main.async(execute: { () -> Void in
print(json)
SVProgressHUD.dismiss()
})
} catch {
print(error)
SVProgressHUD.dismiss()
SVProgressHUD.showError(withStatus: "Connection Failed.")
}
}
task.resume()
i created soap web services and trying to connect actually it was working before updating xcode after update it occurred a few mistakes ass you see below. Any idea how can i fix it! Thank you.
Try this without ConnectionDataDelegate
func servisRun(xml:String!){
let soapMessage = xml
let msgLength = String(describing: soapMessage?.characters.count)
let url = URL(string: "http....")
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)
let session = URLSession.shared
let task = session.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)
}
task.resume()
let xmlParser = XMLParser(data: mutableData as Data)
xmlParser.delegate = self
xmlParser.parse()
xmlParser.shouldResolveExternalEntities = true
}
Im attemping to make a HTTPRequest using NSURLSession. When I set the full url the request returns the correct data but when using parameters (NSJSONSerialization.dataWithJSONObject -> HTTPBody I get this error
error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."
is there something im doing wrong here?
let json = ["api_key": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"]
do {
let jsonData = try NSJSONSerialization.dataWithJSONObject(json, options: .PrettyPrinted)
let url = NSURL(string: "https://api.themoviedb.org/3/discover/movie")!
let request = NSMutableURLRequest(URL: url)
request.HTTPBody = jsonData
request.HTTPMethod = "GET"
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in
if error != nil{
print("Error -> \(error)")
return
}
do {
let result = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject]
print("Result -> \(result)")
} catch {
print("Error -> \(error)")
}
}
task.resume()
} catch {
print(error)
}
}
This is not a duplicate! I looked at the suggested answer (none of them worked) before asking this question
In your case that issue can be solved by changing the request.HTTPMethod = "GET" to request.HTTPMethod = "POST"
You should not send HTTP Body in the get request, to send the data with the body you should change HTTPMethod to post
Note: Please check if this api method supports POST requests, if it don't support post you can't use it with http body/post, as per doc i only find 'get' request for the discover/movie which can be like this:
let url = NSURL(string: "http://api.themoviedb.org/3/discover/movie?api_key=YOUR_API_KEY")!
let request = NSMutableURLRequest(URL: url)
request.addValue("application/json", forHTTPHeaderField: "Accept")
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request) { data, response, error in
if let response = response, data = data {
print(response)
print(String(data: data, encoding: NSUTF8StringEncoding))
} else {
print(error)
}
}
task.resume()

I'm trying to upload an image to the server. As for now, I get an error response which checks if name='image', and the error means that it's not. The line where I set it is this:
body.appendString("Content-Disposition: form-data; name='image'; filename='test.jpg'")
my full code of the POST request is this: I do get a 200 and the only problem is with the name parameter which I really can't figure out.
func imageUploadRequest()
{
let stringUrl = "http://88.162.41.55/app_backend/public/api/v1/image?_r=1836486547600309"
let URL = NSURL(string: stringUrl.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)!
let request = NSMutableURLRequest(URL: URL)
request.HTTPMethod = "POST";
request.setValue("Bearer \(jwtToken)", forHTTPHeaderField: "Authorization")
let boundary = generateBoundaryString()
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let imageData = UIImageJPEGRepresentation(image, 1)
if(imageData == nil) {
print("image data is nil")
return
}
let body:NSMutableData = NSMutableData()
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name='image'; filename='test.jpg'")
body.appendString("Content-Type: image/jpg")
body.appendData(imageData!)
body.appendString("\r\n")
body.appendString("--\(boundary)--\r\n")
request.HTTPBody = body
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}
let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print(" response = \(responseString!)")
do {
let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary
print("json", json)
} catch {
print("bad things happened")
}
}
task.resume()
}
Any ideas? Thank you so much!!
