How to POST request in Swift - ios

Question

I have this API http://my-api.mydoctorfinder.com/
that will return a bool value depending on the email and password you have entered.
My problem is it will always return false despite using the correct email and password.
I was thinking that I might have not sent the right parameter since I created a dictionary containing the email and password. Then passed it on NSJSONSerialization.dataWithJSONObject method
By the way, I was using SwiftyJson.
This is my code
//creates a dictionary and calls the PostRequest method
func attemptLogIn( email: String, password: String) {
let route = loggerURL
let body: [String:String] = ["email":email, "password":password]
makeHTTPPostRequest(route, body: body)
}
//performs post request
private func makeHTTPPostRequest(path: String, body: [String: AnyObject]) {
let request = NSMutableURLRequest(URL: NSURL(string: path)!)
// Set the method to POST
request.HTTPMethod = "POST"
do {
// Set the POST body for the request
let jsonBody = try NSJSONSerialization.dataWithJSONObject(body, options: .PrettyPrinted)
request.HTTPBody = jsonBody
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
if let jsonData = data {
let json:JSON = JSON(data: jsonData)
//onCompletion(json, nil)
print("The Response: ")
print(json)
} else {
//onCompletion(nil, error)
print("The Response: ")
print("Hello")
}
})
task.resume()
} catch {
// Create your personal error
//onCompletion(nil, nil)
}
}

Answer 1

The response is simply a true or false i.e. its not a json object.
So i would suggest don't use Swifty son instead use Alamofire.
Following code should work for you:-
let myParameters = [
"email": "your email id",
"password": "your password"]
Alamofire.request(.POST, "http://my-api.mydoctorfinder.com/ ", parameters: myParameters)
.response { request, response, data, error in
print(request)
print(response)
if(response == true)
{
// do your thing
}
print(error)
}
Note: There might be a need to typecast response to bool
Also following is the screenshot of the link you gave, it returns true(and not a json object) [After registration, i tried to login with same credentials]

Try to create JSON object using NSJSONSerialization in this way:
request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(body, options: [])
I assume that problem is in .PrettyPrinted constant.
Edit:
Also try adding correct content-type:
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")

Here is the swift post request to get data :
func retriveTextDataByPost(requestURL:String, params: NSDictionary, handler:((dict:NSDictionary?) -> Void)) {
let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: configuration, delegate: self, delegateQueue: nil)
let url = NSURL(string: requestURL)
let request = NSMutableURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.UseProtocolCachePolicy, timeoutInterval: 60)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPMethod = "POST"
do {
let postData = try NSJSONSerialization.dataWithJSONObject(params, options:NSJSONWritingOptions.PrettyPrinted)
request.HTTPBody = postData
let postDataTask = session.dataTaskWithRequest(request) { (data:NSData?, response:NSURLResponse?, error:NSError?) -> Void in
if data != nil {
do {
let dictResult:NSDictionary = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary
handler(dict: dictResult)
} catch { }
}
}
postDataTask.resume()
} catch { }
}

Check your keys for email and password with required input for APIs
Check your login URL
