Authorization Header not setting in Alamofire 5? - ios

Question

I am setting the basic auth token to my URLRequest and using Alamofire to execute.
I set 3 headers, content, accept and auth...content and accept are visible in the network traffic but auth is not. It is available if i print the headers of the URLRequest before its sent...
Any ideas here? as i dont see how its removing the auth header before posting
Code as follows:
// Construct url
let url = try APIConstants.baseUrl.asURL()
// Append path
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
// Determine HTTP method
urlRequest.httpMethod = method.rawValue
let headers: HTTPHeaders = [
.contentType(APIConstants.ContentType.json.rawValue),
.accept(APIConstants.ContentType.json.rawValue),
]
if let token = token {
urlRequest.addValue("\(APIConstants.API.token.rawValue) \(token.key)",
forHTTPHeaderField: "Authorization")
}
urlRequest.headers = headers
// Add http body to request
if let parameters = parameters {
do {
let data = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted)
urlRequest.httpBody = data
} catch (_) {
print("APIRouter: Failed to parse body into request.")
}
}
//Encoding
let encoding: ParameterEncoding = {
switch method {
case .get:
return URLEncoding.default
default:
return JSONEncoding.default
}
}()
return try encoding.encode(urlRequest, with: parameters)
}
In my rest client i execute like this:
return Observable<T>.create { observer in
let request = AF.request(urlConvertible).responseDecodable { (response: DataResponse<T, AFError>) in
switch response.result {
case .success(let value):
observer.onNext(value)
observer.onCompleted()
case .failure(let error):
switch response.response?.statusCode {
case 403:
observer.onError(APIError.forbidden)
case 404:
observer.onError(APIError.notFound)
case 409:
observer.onError(APIError.conflict)
case 500:
observer.onError(APIError.internalServerError)
default:
observer.onError(error)
}
}
}
return Disposables.create {
request.cancel()
}
}
}
Edit:
Updated func to show further issue:
func asURLRequest() throws -> URLRequest {
// Construct url
let url = try APIConstants.baseUrl.asURL()
// Append path
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
// Determine HTTP method
urlRequest.httpMethod = method.rawValue
let headers: HTTPHeaders = [
.contentType(APIConstants.ContentType.json.rawValue),
.accept(APIConstants.ContentType.json.rawValue),
.authorization("Token a5555485aa251b28fdsfasdfdsb379c131fddad")
]
urlRequest.headers = headers
// Add http body to request
if let parameters = parameters {
do {
let data = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted)
urlRequest.httpBody = data
} catch (_) {
print("APIRouter: Failed to parse body into request.")
}
}
//Encoding
let encoding: ParameterEncoding = {
switch method {
case .get:
return URLEncoding.default
default:
return JSONEncoding.default
}
}()
return try encoding.encode(urlRequest, with: parameters)
}

Answer 1

After setting the Authorization header in your URLRequest:
urlRequest.addValue("\(APIConstants.API.token.rawValue) \(token.key)", forHTTPHeaderField: "Authorization")
then you override all the request's headers by setting headers property:
urlRequest.headers = headers
A nice solution would be to update the headers that you already created above, like this:
var headers: HTTPHeaders = [
.contentType(APIConstants.ContentType.json.rawValue),
.accept(APIConstants.ContentType.json.rawValue),
]
if let token = token {
headers.add(.authorization("\(APIConstants.API.token.rawValue) \(token.key)"))
}
urlRequest.headers = headers

Another solution is to use KeyValue pair as follows:
var header: HTTPHeaders = [:]
if let token = getValueFromUserDefaults(keyName: "authToken") as? String {
header["Authorization"] = token
}
I always use this method. It's more handy for me.
