iOS: Sending push notification to firebase services via url request - ios

Question

I'm building an test app to send push notifications here is my code:
static func sendRequestPush(){
let json: [String: Any] = ["to": "key",
"priority": "high",
"notification": ["body":"Hello1", "title":"Hello world","sound":"default"]]
let urlStr:String = "https://fcm.googleapis.com/fcm/send"
let url = URL(string:urlStr)
let jsonData = try? JSONSerialization.data(withJSONObject: json)
var request = URLRequest(url: url!)
request.httpMethod = "POST"
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
if let responseJSON = responseJSON as? [String: Any] {
print(responseJSON)
}
}
task.resume()
}
The problem is I don't get any response from googleapis neither the push notification. I get the push notification from dash board but not from my code.
Any of you knows what I'm doing wrong?
I'll really appreciate your help.

Try the below code, It works like charm :)
func sendRequestPush() {
// create the request
let url = URL(string: "https://fcm.googleapis.com/fcm/send")
let request = NSMutableURLRequest(url: url!)
request.httpMethod = "POST"
request.setValue("key=putYourLegacyServerKeyHere", forHTTPHeaderField: "authorization")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let parameters = ["to": "putYourFCMToken",
"priority": "high",
"notification": ["body":"Hello1", "title":"Hello world","sound":"default"]] as [String : Any]
do {
request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body
} catch let error {
print(error.localizedDescription)
}
let config = URLSessionConfiguration.default
let session = URLSession(configuration: config)
let dataTask = session.dataTask(with: request as URLRequest) { data,response,error in
let httpResponse = response as? HTTPURLResponse
if (error != nil) {
print(error!)
} else {
print(httpResponse!)
}
guard let responseData = data else {
print("Error: did not receive data")
return
}
do {
guard let responseDictionary = try JSONSerialization.jsonObject(with: responseData, options: [])
as? [String: Any] else {
print("error trying to convert data to JSON")
return
}
print("The responseDictionary is: " + responseDictionary.description)
} catch {
print("error trying to convert data to JSON")
return
}
DispatchQueue.main.async {
//Update your UI here
}
}
dataTask.resume()
}
"putYourLegacyServerKeyHere" change this according to your key that you can get in FCM Console
"putYourFCMToken" change this with the fcm token you got in didReceiveRegistrationToken (FCM Delegate)
