Alamofire 4 Swift 3 GET request with parameters - ios

Question

I'm building a network stack using Alamofire 4 and Swift 3. Following the Alamofire guidelines I've created a router for the endpoints of the services. I'm currently using the free API of OpenWeatherMap but I'm finding problems in order to create a get request.
That's the url needed: http://api.openweathermap.org/data/2.5/weather?q=Rome&APPID=MY_API_KEY. Pasted on a browser, and using a real API Key it works and gives me back my nice json full of info about the weather in the given location.
On my App I can insert the parameters as Dictionary but I cannot find a way to append the api key at the end of the url.
That's my enum router:
enum OWARouter: URLRequestConvertible {
case byCityName(parameters: Parameters)
// MARK: Url
static let baseURLString = "http://api.openweathermap.org"
static let apiKey = "MY_APY_KEY"
static let pathApiKey = "&APPID=\(apiKey)"
var method: HTTPMethod {
switch self {
case .byCityName:
return .get
}
}
var path: String {
switch self {
case .byCityName:
return "/data/2.5/weather"
}
}
// MARK: URLRequestConvertible
func asURLRequest() throws -> URLRequest {
let url = try OWARouter.baseURLString.asURL()
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
switch self {
case .byCityName(let parameters):
urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters)
print((urlRequest.url)!)
}
urlRequest.httpMethod = method.rawValue
return urlRequest
}
}
When I log my (urlRequest.url)! I have this: http://api.openweathermap.org/data/2.5/weather?q=Rome but I cannot find a way to add the apiKey.
What am I doing wrong?
I've also made an ugly test adding this code after the print:
var urlRequest2 = URLRequest(url: (urlRequest.url)!.appendingPathComponent(OWARouter.pathApiKey))
print("URL2: \(urlRequest2)")
And the log is URL2: http://api.openweathermap.org/data/2.5/weather/&APPID=My_API_KEY?q=Rome
How come the api key is in the middle?
If you need this is the simple request code:
Alamofire.request(OWARouter.byCityName(parameters: ["q":"Rome"])).responseJSON { response in
print(response.request)
print(response.response)
print(response.data)
print(response.result)
debugPrint(response)
if let JSON = response.result.value {
print("json: \(JSON)")
}
}
Another question...
If I use as parameters ["q":"Rome, IT"], my output url is: http://api.openweathermap.org/data/2.5/weather?q=Rome%2CIT
How to keep the comma?
Thank you!

Answer 1

Swift - 5 Alamofire 5.0 Updated Code (just Change AF.request Method according to your requirement you can add Parameters headers and intercepter as well )
Alamofire.request(url, method: .get, encoding: JSONEncoding.default)
.responseJSON { response in
switch response.result {
case .success(let json):
print(json)
DispatchQueue.main.async {
// handle your code
}
case .failure(let error):
print(error)
}
}

Answer 2

Used below lines of code:
func getRequestAPICall(parameters_name: String) {
let todosEndpoint: String = "your_server_url" + "parameterName=\(parameters_name)"
Alamofire.request(todosEndpoint, method: .get, encoding: JSONEncoding.default)
.responseJSON { response in
debugPrint(response)
if let data = response.result.value{
// Response type-1
if (data as? [[String : AnyObject]]) != nil{
print("data_1: \(data)")
}
// Response type-2
if (data as? [String : AnyObject]) != nil{
print("data_2: \(data)")
}
}
}
}

Answer 3

func AlamofireGetCode()
{
var url:String!
url = "https://jsonplaceholder.typicode.com/comments"
Alamofire.request(url, method: .get, encoding: JSONEncoding.default)
.responseJSON { response in
switch response.result{
case .success(let json):
print(json)
DispatchQueue.main.async {
print(json)
self.mainarray = json as? NSArray
print(self.mainarray as Any)
self.mytableviewreload.reloadData()
}
case .failure(let error):
print(error)
}
}
}

Answer 4

I've found a solution... the Api Key is simply a parameter to send to the request. So the code to change is not in the router but in the request function:
Alamofire.request(OWARouter.byCityName(parameters: ["q":"Rome","APPID":"MY_API_KEY"])).responseJSON { response in
print(response.request)
//print(response.response)
//print(response.data)
//print(response.result)
//debugPrint(response)
if let JSON = response.result.value {
print("json: \(JSON)")
}
}
EDIT: the comma issue do not gives me any problem now. Thank you.

Swift 5+
Use AF.request
let todosEndpoint: String = "https://jsonplaceholder.typicode.com/todos/1"
let request = AF.request(todosEndpoint)
request.responseJSON { (data) in
print("Response", data)
}

import UIKit
import Alamofire
class APIWRAPPER: NSObject {
static let instance = APIWRAPPER()
func LoginAPI(Uname : String , Password : String) {
let requestString =
"http://************php/v1/sign-in"
let params = ["user_name": Uname,
"password": Password]
Alamofire.request(requestString,method: .get, parameters: params, encoding: JSONEncoding.prettyPrinted, headers: [:]).responseJSON { (response:DataResponse<Any>) in
switch(response.result) {
case .success(_):
if response.result.value != nil
{
print("response : \(response.result.value!)")
}
else
{
print("Error")
}
break
case .failure(_):
print("Failure : \(response.result.error!)")
break
}
}
}
