DioError [DioErrorType.RESPONSE]: Http status error [405]

I am creating a post request Using Dio, this is my FormData params,

    FormData formData = FormData.fromMap({
      'wallet_id': '${dropdownValue.walletId}',
      'member_id': '${_loginModel.memberId}',
      'draw_amount': withdrawalAmountContoller.text,
      'login_password': passwordController.text,
    });

then I am passing params like this,

Response response = await dio.post(url, data: params);

But I am getting an error on request,

ERROR[DioError [DioErrorType.RESPONSE]: Http status error [405]] => PATH: https://vertoindiapay.com/pay/api/withdraw

E/flutter ( 6703): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: DioError [DioErrorType.RESPONSE]: Http status error [405]

E/flutter ( 6703): #0 DioMixin._request._errorInterceptorWrapper. (package:dio/src/dio.dart:848:13)

Please help me solve this. My URL is=> https://vertoindiapay.com/pay/api/withdraw

Although this is working fine in postman,

This particular problem occurs when the response you expect (in JSON) doesn't match the response you are looking forward to receiving.

if this is your code,

Response response = await dio.post(url, data: params);

Check the Response model if it matches with the JSON it receives in the Postman response.

  Future<void> signUpUser() async {
    final formData = {
      'username': 'test1',
      'password': 'abcdefg',
      'grant_type': 'password',
    };
 try {
    Dio _dio = new Dio();
    _dio.options.contentType = Headers.formUrlEncodedContentType;

    final responseData = await _dio.post<Map<String, dynamic>>('/token',
        options: RequestOptions(
           
            method: 'POST',
            headers: <String, dynamic>{},
            baseUrl: 'http://52.66.71.229/'),
        data: formData);

   
      print(responseData.toString());
    } catch (e) {
      final errorMessage = DioExceptions.fromDioError(e).toString();
      print(errorMessage);
    }

  }



 class DioExceptions implements Exception {
  
  DioExceptions.fromDioError(DioError dioError) {
    switch (dioError.type) {
      case DioErrorType.CANCEL:
        message = "Request to API server was cancelled";
        break;
      case DioErrorType.CONNECT_TIMEOUT:
        message = "Connection timeout with API server";
        break;
      case DioErrorType.DEFAULT:
        message = "Connection to API server failed due to internet connection";
        break;
      case DioErrorType.RECEIVE_TIMEOUT:
        message = "Receive timeout in connection with API server";
        break;
      case DioErrorType.RESPONSE:
        message =
            _handleError(dioError.response.statusCode, dioError.response.data);
        break;
      case DioErrorType.SEND_TIMEOUT:
        message = "Send timeout in connection with API server";
        break;
      default:
        message = "Something went wrong";
        break;
    }
  }

  String message;

  String _handleError(int statusCode, dynamic error) {
    switch (statusCode) {
      case 400:
        return 'Bad request';
      case 404:
        return error["message"];
      case 500:
        return 'Internal server error';
      default:
        return 'Oops something went wrong';
    }
  }

  @override
  String toString() => message;
}

So I had this issue. So I found out that the headers you use in Postman should match the headers you are using in Dio. Like for example

  headers: {
      'Accept': "application/json",
      'Authorization': 'Bearer $token',
    },

and my Postman looks like this Postman

Apparently Dio behaves like postman when it comes to headers too so apparently if the headers from postman mis-match then it will throw an error.

Well in plain terms Dio would infer the content-type by itself just like postman would do.

Try to pass content type

final response = await Dio().post(Url,
        options: Options(contentType: 'multipart/form-data'), data: formData);

I had the same error, the BaseOptions was having different method name, other than POST... when i changed it back to POST it worked. Not sure if DIO package accepts using other than POST methods to call a Post method in API.

Please try passing the params as JSON encoded.

Response response = await dio.post(url, data: json.encode(params));

Hope this helps!
