api calls - Flutter-CodePudding

I'm trying to make a api call but I can't success, everything goes fine until the call, and there stop everything and the function finish, what I do wrong?

Future<String> get() async {
var url = Uri.parse("https://10.0.2.2:7021/api/Auth/login");

var headers = {"content-type": "application/json"};
final msg = jsonEncode(
    {"username": "string", "password": "string", "email": "string"});

var response = await http!.post(url, body: msg, headers: headers);

if (response.statusCode == 200) {
  var data = jsonDecode(response.body);
  print("Correct");
  return "Correct";
} else {
  print(response.statusCode);

  print("User not allowed");
  throw Exception("User not allowed");
}

}

Mistake comes here

You have probably imported the "wrong" http. Do it like that:

import 'package:http/http.dart' as http;

You dont need to write http! because http is a package and is never null and since you are doing http! I guess you imported something wrong in your code.

EDIT:

Maybe your device can't reach 10.0.2.2 (or that port), you should set a timeout to find it out fast:

http.post(url, body: msg, headers: headers).timeout(
  const Duration(seconds: 3),
  onTimeout: () {
    // request timed out
    return http.Response('Error', 408);
  },
);

CodePudding user response：

Have you imported http package like this?

import 'package:http/http.dart' as http;

And use case like this

var response = await http.post(url, body: msg, headers: headers);

add .php to login in the url : https://10.0.2.2:7021/api/Auth/login.php if you are working with php or .py for python
