How to Post/Get with body in Swift - node.js

Question

Im trying to connect to an api I made with node.js but it looks like there isn't a clear way to do it if there requires a body in the request. Im able to connect to it with postman on localhost because there i can set the params in the body but when i use the heroku url it throws an error. I read that apple made it so swift can no longer make requests with a body anymore. In another project i was able to successfully connect to an api made with python but instead of passing the data to the body it was passed as params. How can I change the api/swift code to accept the data as params in swift instead of the body?
Heres the function call in swift:
func logoin() {
let params: Parameters = [
"email" : "test#email.com",
"password" : "1234"
]
AF.request("https://app_name.herokuapp.com/user/login", method: .post, parameters: params, encoding: JSONEncoding.default, headers: ["Content-Type": "application/json"]).responseJSON { response in
if let error = response.error {
print(error)
}
else{
let jsonData = try! JSON(data: response.data!)
print("json data", response)
}
}
}
