how to provide authentication token to login api by alamofire4 and swift3 - ios

Question

all.
I can get authentication token by login. but I can authenticate on my server by swift and alamofire.
this is Postman. as you see, if i have token, i can be authenticated on myserver.
this is swift viewcontroller.
import UIKit
import Alamofire
import SwiftyJSON
import KeychainAccess
class ViewController: UIViewController {
let authLoginUrl = "http://ec2-52-79-155-29.ap-northeast-2.compute.amazonaws.com:8000/rest-auth/login/"
let keychain = Keychain(service: "wanote")
let projectUrl = "http://ec2-52-79-155-29.ap-northeast-2.compute.amazonaws.com:8000/api/user/ryulstory"
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let username = "username"
let password = "1234!"
self.doAuth(username: username, password: password)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func doAuth(username:String, password:String) {
let params = ["username": username, "password": password]
var authToken = Alamofire.request(self.authLoginUrl, method: .post, parameters: params)
authToken.responseJSON { response in
let statusCode = response.response?.statusCode ?? 0
switch statusCode {
case 200...299:
let jsonData = JSON(response.result.value)
if let token = jsonData["key"].string{
self.keychain["token"] = token
self.getProjects()
}
case 400...499:
print("Server responded no")
case 500...599:
print("Server error")
default:
print("There was an error with your request")
}
}
}
func getProjects(){
if let token = self.keychain["token"] {
if let Purl = URL(string: self.projectUrl){
var mutableUrlRequest = URLRequest(url: Purl)
mutableUrlRequest.httpMethod = "GET"
mutableUrlRequest.setValue("Token " + token, forHTTPHeaderField: "Authorization")
var manager = Alamofire.SessionManager.default
var getProjectsRequest = manager.request(mutableUrlRequest)
getProjectsRequest.responseJSON { response in
print(response.data)
}
}
} else {
print("no token")
}
}
}
I checked getting token by function doAuth. it is correctly operating.
function getprojects makes error status code 401.
I think there are problem in function getprojects. but i can't find it.
could you help me?
Best regards.

Answer 1

It goes to 401 because you are sending the request without the header authorization.
With Alamofire you can set the header Authorization like this.
let url = "URL_LOGIN"
//Get token logic
let token = ""
let headers = ["Authorization": "Token \(token)"]
let params = ["user": "", "pass":""] //This goes in the body of the request
Alamofire.request(url, method: .post, parameters: params, encoding: URLEncoding.default, headers: headers).responseJSON { (response) in
if let value = response.result.value {
print(value)
}
}
With this you'll send the headers in the request to get what you want.

I think this part have the header authorization.
is it wrong?
mutableUrlRequest.httpMethod = "GET"
mutableUrlRequest.setValue("Token " + token, forHTTPHeaderField: "Authorization")
var manager = Alamofire.SessionManager.default
var getProjectsRequest = manager.request(mutableUrlRequest)
