I have my controller like this -
def create
if (@user = User.find_by_email(params[:email])) && @user.valid_password?(params[:password])
render json: @user.as_json(only: [:email,:authentication_token]),status: :created
else
render json:('Unauthorized Access')
end
end
When I use Postman to make this request, I choose Body, and form data and adds in the email and password. And this WORKS
How to use swift to do the same? This is what I have tried
let url = URL(string: "http://localhost:3000/api/v1/user_serialized/")
let config = URLSessionConfiguration.default
let request = NSMutableURLRequest(url: url!)
request.httpMethod = "POST"
let bodyData = "[email protected]&password=Test1234"
request.httpBody = bodyData.data(using: String.Encoding.utf8);
let session = URLSession(configuration: config)
let task = session.dataTask(with: url! as URL, completionHandler: {(data, response, error) in
let json = JSON(data:data!)
debugPrint(json)
})
task.resume()
I think you should pass your request instead of the url to session.dataTask
here is how my code looks like:
private let url = URL(string: "http://example.com/")!
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()
}
}
I have made a Custom HTTP class where we can sent url, parameter and we will get Data from API. Below is the class.
import Foundation
//HTTP Methods
enum HttpMethod : String {
case GET
case POST
case DELETE
case PUT
}
class HttpClientApi: NSObject{
//TODO: remove app transport security arbitary constant from info.plist file once we get API's
var request : URLRequest?
var session : URLSession?
static func instance() -> HttpClientApi{
return HttpClientApi()
}
func makeAPICall(url: String,params: Dictionary<String, Any>?, method: HttpMethod, success:@escaping ( Data? ,HTTPURLResponse? , NSError? ) -> Void, failure: @escaping ( Data? ,HTTPURLResponse? , NSError? )-> Void) {
request = URLRequest(url: URL(string: url)!)
logging.print("URL = \(url)")
if let params = params {
let jsonData = try? JSONSerialization.data(withJSONObject: params, options: .prettyPrinted)
request?.setValue("application/json", forHTTPHeaderField: "Content-Type")
request?.httpBody = jsonData//?.base64EncodedData()
//paramString.data(using: String.Encoding.utf8)
}
request?.httpMethod = method.rawValue
let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForRequest = 30
configuration.timeoutIntervalForResource = 30
session = URLSession(configuration: configuration)
//session?.configuration.timeoutIntervalForResource = 5
//session?.configuration.timeoutIntervalForRequest = 5
session?.dataTask(with: request! as URLRequest) { (data, response, error) -> Void in
if let data = data {
if let response = response as? HTTPURLResponse, 200...299 ~= response.statusCode {
success(data , response , error as? NSError)
} else {
failure(data , response as? HTTPURLResponse, error as? NSError)
}
}else {
failure(data , response as? HTTPURLResponse, error as? NSError)
}
}.resume()
}
}
Now you can refer below code to get how to make an API call.
var paramsDictionary = [String:Any]()
paramsDictionary["username"] = "BBB"
paramsDictionary["password"] = "refef"
HttpClientApi.instance().makeAPICall(url: "Your URL", params:paramsDictionary, method: .POST, success: { (data, response, error) in
// API call is Successfull
}, failure: { (data, response, error) in
// API call Failure
})
