401 alamofire get request with headers - swift

Question

I'm getting error 401 trying to make a request using custom headers, when I print the headers, it is there, just like I make a call using postman, the difference is that in postman the request works, but in the app I get that error, I don't think it is the headers, because as I said they are there, what am I missing here?
func getUserByID(completion: #escaping CompletionHandler) {
let url_id = URL_USER_ID + String(self.userID)
let header:HTTPHeaders = [
"Content-Type": "application/json",
"Authorization": "Token " + AuthService.instance.authToken
]
Alamofire.request(url_id, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: header).responseJSON{
(response) in
guard let data = response.data else {return}
let json = try? JSON(data: data)
if response.response?.statusCode == 200 {
let user = json!["user"]
let id = user["id"].stringValue
let email = user["email"].stringValue
let img = user["img"].stringValue
let tipo_usuario = user["tipo_usuario"].intValue
let nome_comp = user["nome_comp"].stringValue
let end_cep = user["end_cep"].stringValue
let end_logr = user["end_logr"].stringValue
let end_num = user["end_num"].stringValue
let end_bairro = user["end_bairro"].stringValue
let end_complm = user["end_complm"].stringValue
let cidade = user["cidade"]
let cidadeID = cidade["id"].intValue
let cidadeNome = cidade["nome"].stringValue
let cidadeEstado = cidade["estado"].stringValue
let telefone = user["telefone"].stringValue
let whatsapp = user["whatsapp"].stringValue
let pontos = user["pontos"].intValue
let cnpj_cpf = user["cnpj_cpf"].stringValue
let razao_social = user["razao_social"].stringValue
let nome_fantasia = user["nome_fantasia"].stringValue
let insc_estadual = user["insc_estadual"].stringValue
let categoria = user["categoria"].intValue
let nota = user["nota"].stringValue
let cidadeUser = Cidades(id: cidadeID, nome: cidadeNome, estado: cidadeEstado)
UserDataService.instance.setUserData(id: id, email: email, img: img, tipo_usuario: tipo_usuario, nome_comp: nome_comp, end_cep: end_cep, end_logr: end_logr, end_num: end_num, end_bairro: end_bairro, end_complm: end_complm ,cidade: cidadeUser, telefone: telefone, whatsapp: whatsapp, pontos: pontos, cnpj_cpf: cnpj_cpf, razao_social: razao_social, nome_fantasia: nome_fantasia, insc_estadual: insc_estadual, categoria: categoria, nota: nota)
self.userEmail = email
self.userID = Int(id)!
completion(true)
} else if response.response?.statusCode == 400 {
completion(false)
} else {
debugPrint(response.result.error as Any)
}
}

and the error message:

I faced similar issue like:
Postman performed request with success, but alamofire
with 401 JWT Token not found. So the response was a failure, but server performed action for the request like it was success.
In my case it turned out to be redirection.
You should check if it is not due to redirection, because by default Alamofire doesn't pass authorization field in header to redirected request (this seems to be reasonable behavior in such case).
So to make authorization transmissible you can do it like:
Alamofire.SessionManager.default.delegate.taskWillPerformHTTPRedirection = { session, task, response, request in
var redirectedRequest = request
if let originalRequest = task.originalRequest,
let headers = originalRequest.allHTTPHeaderFields,
let authorizationHeaderValue = headers["Authorization"]
{
var mutableRequest = request
mutableRequest.setValue(authorizationHeaderValue, forHTTPHeaderField: "Authorization")
redirectedRequest = mutableRequest
}
return redirectedRequest
}
//now use your requests i.e:
Alamofire.request(url, method: .post, parameters: params, encoding: JSONEncoding.default, headers: header)
.validate()
.responseJSON(completionHandler: { (response) in
switch response.result {
case .success:
//success
break
case .failure(let error):
//fail
break
}
})
If you want to return to default behavior just simply:
Alamofire.SessionManager.default.delegate.taskWillPerformHTTPRedirection = nil
