post function

Future<Response> post(
  1. Uri url,
  2. {Map<String, String>? headers,
  3. Object? body,
  4. Encoding? encoding}
)

Sends an HTTP POST request with the given headers and body to the given URL.

body sets the body of the request. It can be a String, a List or a Map<String, String>. If it's a String, it's encoded using encoding and used as the body of the request. The content-type of the request will default to "text/plain".

If body is a List, it's used as a list of bytes for the body of the request.

If body is a Map, it's encoded as form fields using encoding. The content-type of the request will be set to "application/ x-www-form-urlencoded"; this cannot be overridden.

encoding defaults to utf8.

A HttpStatusException will be thrown if any non-200 HTTP status code is returned from the request.

Implementation

Future<Response> post(
  Uri url, {
  Map<String, String>? headers,
  Object? body,
  Encoding? encoding,
}) async {
  final response =
      await http.post(url, headers: headers, body: body, encoding: encoding);
  if (response.statusCode != 200) throw HttpStatusException(response);
  return response;
}
