Where did setHTTPMethod, setURL and setHTTPBody go in swift? - ios

Question

I am trying to implement HTTP requests.
Here is the objective C implementation
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
I started by writing:
let request = NSMutableURLRequest()
request .setValue(postLength, forHTTPHeaderField: "Content-Lenght")
request .setValue(application/json, forHTTPHeaderField: Accept)
1.The json request is giving me an error.
2.I cannot convert the setURL and SetHTTPBody from objective C to swift. I could not find
the option for these.
Any help would be appreciated.
Thank you.

Answer 1

They have become properties. Most setter methods with a single argument have become properties.
The problem with your json line is you did not have quotes around "Accept."
let request = NSMutableURLRequest()
request.url = url
request.HTTPMethod = "POST"
request.setValue(postLength, forHTTPHeaderField:"Content-Length")
request.setValue("application/json", forHTTPHeaderField:"Accept")
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField:"Content-Type")
request.postBody = postData

Here is how i do it in swift :
var request : NSMutableURLRequest = NSMutableURLRequest()
request.URL = NSURL(string: url)
request.HTTPMethod = "POST"
request.setValue(postLength, forHTTPHeaderField: "Content-Length")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.HTTPBody = jsonData

var request: NSMutableURLRequest?
let HTTPMethod: String = "POST"
var timeoutInterval: NSTimeInterval = 60
var HTTPShouldHandleCookies: Bool = false
request = NSMutableURLRequest(URL: url)
request!.HTTPMethod = HTTPMethod
request!.timeoutInterval = timeoutInterval
request!.HTTPShouldHandleCookies = HTTPShouldHandleCookies
let boundary = "----------SwIfTeRhTtPrEqUeStBoUnDaRy"
let contentType = "multipart/form-data; boundary=\(boundary)"
request!.setValue(contentType, forHTTPHeaderField:"Content-Type")
var body = NSMutableData();
let tempData = NSMutableData()
let fileName = filenames + ".jpg" //"prueba.jpg"
let parameterName = "userfile"
let mimeType = "application/octet-stream"
tempData.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
let fileNameContentDisposition = fileName != nil ? "filename=\"\(fileName)\"" : ""
let contentDisposition = "Content-Disposition: form-data; name=\"\(parameterName)\"; \(fileNameContentDisposition)\r\n"
tempData.appendData(contentDisposition.dataUsingEncoding(NSUTF8StringEncoding)!)
tempData.appendData("Content-Type: \(mimeType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
tempData.appendData(imageData)
tempData.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(tempData)
body.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
request!.setValue("\(body.length)", forHTTPHeaderField: "Content-Length")
request!.HTTPBody = body
var vl_error :NSErrorPointer = nil
var responseData = NSURLConnection.sendSynchronousRequest(request,returningResponse: nil, error:vl_error)
var results = NSString(data:responseData, encoding:NSUTF8StringEncoding)
println("finish \(results)")

I am calling the json on login button click
#IBAction func loginClicked(sender : AnyObject){
var request = NSMutableURLRequest(URL: NSURL(string: kLoginURL)) // Here, kLogin contains the Login API.
var session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(self.criteriaDic(), options: nil, error: &err) // This Line fills the web service with required parameters.
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
var strData = NSString(data: data, encoding: NSUTF8StringEncoding)
println("Body: \(strData)")
var err1: NSError?
var json2 = NSJSONSerialization.JSONObjectWithData(strData.dataUsingEncoding(NSUTF8StringEncoding), options: .MutableLeaves, error:&err1 ) as NSDictionary
if(err) {
println(err!.localizedDescription)
}
else {
var success = json2["success"] as? Int
println("Succes: \(success)")
}
})
task.resume()
}
Here, I have made a seperate dictionary for the parameters.
var params = ["format":"json", "MobileType":"IOS","MIN":"f8d16d98ad12acdbbe1de647414495ec","UserName":emailTxtField.text,"PWD":passwordTxtField.text,"SigninVia":"SH"] as NSDictionary
return params
}
