Flutter POST request body returns empty-CodePudding

  String url = 'http://localhost:49430/#/';
  Future save() async {
    var b = json.encode({'email':user.email, 'password':user.password});
    var res = await http.post(Uri.parse(url),
        headers: {'Content-Type' : 'application/json'},
        body : b,);
    print(b);
    print(res.body);
  }

I am attempting to post the username and password, although when I try to print the json body, it returns as empty. There is a server response of 404, which I believe points to the URL being wrong, although it is not. When I print string b, it prints correctly, so it is clearly something to do with the server.

When I print(Uri.base), it returns with the same URL.

CodePudding user response：

it is local server you need to sure it is already running

CodePudding user response：

Instead of sending body as string try send it as map, like this:

 var b = {'email':user.email, 'password':user.password};

and also your url only contains base url, and doesn't have any end point to refer to specific api.
