I want to consume login API (node.js) on my swift code using Alamofire - node.js

Question

Im getting an error while im trying to login:
there's my login service, im sure it works so well because I tested it on postman, and I worked with it already on android, and it works perfectly, encrypted password and salt works so well ..
app.post('/login/',(req,res,next)=>{
var post_data = req.body;
//Extract email and password from request
var user_password = post_data.password;
var email = post_data.email;
con.query('SELECT * FROM user where email=?',[email],function (err,result,fields) {
con.on('error', function (err) {
console.log('[MYSQL ERROR]', err);
});
if (result && result.length)
{
var salt = result[0].salt;
var encrypted_password = result[0].encrypted_password;
var hashed_password = checkHashPassword(user_password, salt).passwordHash;
if (encrypted_password == hashed_password)
res.end(JSON.stringify(result[0]))
else
res.end(JSON.stringify('Wrong Password'))
}
else {
res.json('user not exists!!');
}
});
})
and there's my swift code on btn_login action, im using Alamofire, he shows me an error with the url, but i worked with same url on displaying data from my table at it worked fine
#IBAction func btn_login(_ sender: Any) {
let serverUrl = "https://127.0.0.1:1337/login"
guard let email = emailtf.text, !email.isEmpty else {return}
guard let password = passwordtf.text, !password.isEmpty else {return}
let loginRequest = [
"email" : email,
"password" : password
]
Alamofire.request(serverUrl, method: .post, parameters: loginRequest, encoding: JSONEncoding.default, headers: nil)
.validate(statusCode:200..<300)
.responseJSON { response in
switch response.result {
case .success(let value):
print(value)
break
case .failure(let error):
print(error)
break
}
}
}
and im getting this error on xcode console
["Email": "test", "Password": "test"]

Any help please? Thank you

put your local IP instead of localhost in url .
e.g. http://192.168.1.34:1337/
Also try adding headers in your Alamofire request. Here is an example:
let loginRequest = [
"Email" : self.emailtf.text! as String,
"Password" : self.passwordtf.text! as String
]
let headers = ["Content-Type" : "application/json"]
Alamofire.request(url, method : .post, parameters : loginRequest, encoding :
JSONEncoding.default , headers : headers).responseData { dataResponse in
print(dataResponse.request as Any) // your request
print(dataResponse.response as Any) // your response
}
