urlrequest not sending post request

Hi i am new to IOS App developement.
My code is

func sendRequest<T: Decodable>(api: String, parameters: [String: String]? = nil, outputBlock: @escaping (T) -> () )

guard let url = URL(string: "http://xxyyzz.com/appRegister.php") else return

print("hitting : -", url.absoluteString)

var request = URLRequest(url: url)

request.httpMethod = "POST"

request.addValue("application/json", forHTTPHeaderField: "Content-Type")

request.addValue("application/json", forHTTPHeaderField: "Accept")

let newparam = ["name": "rr", "pass": "123456", "email": "rr@rr.com", "passConfirm":"123456"]

let httpBody = try? JSONSerialization.data(withJSONObject: newparam)

request.httpBody = httpBody

if let data = request.httpBody, let str = String(data: data, encoding: String.Encoding.utf8)

print(str)



URLSession.shared.dataTask(with: request as URLRequest) (data, response, error) in

DispatchQueue.main.async

Indicator.shared.hideProgressView()

if let err = error

print(err.localizedDescription)

return



guard let data = data else return

do

let obj = String(data: data, encoding: String.Encoding.utf8)

print(obj ?? "oberrrrr")





.resume()




and console printed result as per code is below

hitting : - http://xxyyzz.com/appRegister.php
"email":"rr@rr.com","passConfirm":"123456","name":"rr","pass":"123456"

"error":"Please enter all fields."

url and parameters works well on postman that means their is something missing in my code.

just to answer the problem if anyone else faces this.
this code is fine but the problem was with php web-service as the backend developer was not accepting json values as parameter instead form data was need to send.
So, two types of fix can be made here

accept json at backend by adding :-

$postdata = file_get_contents("php://input");
$request = json_decode($postdata, true);

send form data instead json

func sendRequest<T: Decodable>(api: String, parameters: [String: Any]? = nil, outputBlock: @escaping (T) -> () )

guard let url = URL(string: api) else return

print("hitting : -", url.absoluteString)

var request = URLRequest(url: url)

if let parameters = parameters

request.httpMethod = "POST"

var postArr = [String]()

for(key, value) in parameters

postArr.append(key + "=(value)")


let postString = postArr.map String($0) .joined(separator: "&")
request.httpBody = postString.data(using: .utf8)

if let data = request.httpBody, let str = String(data: data, encoding: String.Encoding.utf8)
print(str)



URLSession.shared.dataTask(with: request) (data, response, error) in
DispatchQueue.main.async
Indicator.shared.hideProgressView()
if let err = error
print(err.localizedDescription)
return

guard let data = data else return
do
let obj = try JSONDecoder().decode(T.self, from: data)
outputBlock(obj)
catch let jsonErr
print(jsonErr)


.resume()
