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
}

Hi guys below is my code im using at the moment im making a pos system and talk to a merchant and return talks to a pin pad .
the problem i have is that when i do a purchase for the first time it works 100 percent i get a response from the service
. but when i do another purchase and it does the call nothing happens .
im wondering if the task inst done yet . i dont know whats going on any help
only way i can do another call is by restarting the app
func pinPad(Total:Int,echoData:Int64,retrievalReferenceNumber:Int64, cardAcceptorTerminalId:Int64,cardAcceptorIdCode:Int64) -> String

getdata()
var status:String = ""

var is_URL: String = "http://\(ipcon):\(portcon)/merchant/service"
var session = URLSession.shared

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'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!!

I am learning swift and I send a request to the server with the code below. It works for simple request and I get response from the server. My problem is I can not send a file to server.
code :
let parameters = parameter
let request = NSMutableURLRequest(URL: NSURL(string: requestUrl)!)
let boundaryConstant = "-----Boundary+\(arc4random())\(arc4random())"
let contentType = "multipart/form-data; boundary=" + boundaryConstant
let boundaryStart = "--\(boundaryConstant)\r\n"
let boundaryEnd = "--\(boundaryConstant)--\r\n"
let body:NSMutableString = NSMutableString();
for (key, value) in parameters {
body.appendFormat(boundaryStart)
body.appendFormat("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
body.appendFormat("\(value)\r\n")
}
body.appendFormat(boundaryEnd)
request.HTTPMethod = "POST"
request.setValue(contentType, forHTTPHeaderField: "Content-Type")
request.HTTPBody = body.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)")
}
self.responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)!
print("MMMMMMMM \(self.responseString)")
self.result = self.responseString.dataUsingEncoding(NSUTF8StringEncoding)! as NSData
callback(self.responseString)

As you read here, you should use NSURLSession for HTTP work, it far more flexible and powerful; and I think is destined to replace NSURLconnection...
https://www.objc.io/issues/5-ios7/from-nsurlconnection-to-nsurlsession/
Here is a example for you...
func getMetaData(lePath:String, completion: (string: String?, error: ErrorType?) -> Void) {
// **** get_metadata ****
let request = NSMutableURLRequest(URL: NSURL(string: "https://api.dropboxapi.com/2/files/get_metadata")!)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
request.addValue("Bearer ab-blah-blah", forHTTPHeaderField: "Authorization")
request.addValue("application/json",forHTTPHeaderField: "Content-Type")
request.addValue("path", forHTTPHeaderField: lePath)
let cursor:NSDictionary? = ["path":lePath]
do {
let jsonData = try NSJSONSerialization.dataWithJSONObject(cursor!, options: [])
request.HTTPBody = jsonData
print("json ",jsonData)
} catch {
print("snafoo alert")
}
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
if let error = error {
completion(string: nil, error: error)
return
}
let strData = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Body: \(strData)\n\n")
do {
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions.MutableContainers);
self.jsonParser(jsonResult,field2file: "ignore")
for (key, value) in self.parsedJson {
print("key2 \(key) value2 \(value)")
}
completion(string: "", error: nil)
} catch {
completion(string: nil, error: error)
}
})
task.resume()
}
Great answer above.. Here it's updated for Swift3:
func getMetaData(lePath:String, completion: (string: String?, error: ErrorType?) -> Void) {
// **** get_metadata ****
let request = NSMutableURLRequest(URL: NSURL(string: "https://api.dropboxapi.com/2/files/get_metadata")!)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
request.addValue("Bearer ab-blah-blah", forHTTPHeaderField: "Authorization")
request.addValue("application/json",forHTTPHeaderField: "Content-Type")
request.addValue("path", forHTTPHeaderField: lePath)
let cursor:NSDictionary? = ["path":lePath]
do {
let jsonData = try NSJSONSerialization.dataWithJSONObject(cursor!, options: [])
request.HTTPBody = jsonData
print("json ",jsonData)
} catch {
print("snafoo alert")
}
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
if let error = error {
completion(string: nil, error: error)
return
}
let strData = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Body: \(strData)\n\n")
do {
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions.MutableContainers);
self.jsonParser(jsonResult,field2file: "ignore")
for (key, value) in self.parsedJson {
print("key2 \(key) value2 \(value)")
}
completion(string: "", error: nil)
} catch {
completion(string: nil, error: error)
}
})
task.resume()
}
