already use http, Uri parse......
login working, get addresses not work
Here you go to use dio for network call:
try {
_dio.options.contentType = Headers.jsonContentType;
Response response = await _dio.post(
baseUrl + '/verify-otp',
data: {"activation_token": ""}
);
return response;
} catch (error, stacktrace) {
print("Exception occured: $error stackTrace: $stacktrace");
return error;
}

Alright i'm losing my mind here,
in my flutter app, i'm using this function to perform post requests :
Future<Map> postRequest(String serviceName, Map<String, dynamic> data) async {
var responseBody = json.decode('{"data": "", "status": "NOK"}');
try {
http.Response response = await http.post(
_urlBase + '$_serverApi$serviceName',
body: jsonEncode(data),
);
if (response.statusCode == 200) {
responseBody = jsonDecode(response.body);
//
// If we receive a new token, let's save it
//
if (responseBody["status"] == "TOKEN") {
await _setMobileToken(responseBody["data"]);
// TODO: rerun the Post request
}
}
} catch (e) {
// An error was received
throw new Exception("POST ERROR");
}
return responseBody;
}
The problems are :
I get a ClientException (Not every time)
In another class, I stored the result of this function in a variable, it's supposed to return a Future<Map<dynamic, dynamic>>, when i printed it it shows :
I/flutter ( 9001): Instance of 'Future<Map<dynamic, dynamic>>'
But when i run the same post request directly (without using a function) it worked, and it shows the message that i was waiting for.
note: in both cases (function or not), in the server side it was the same thing.
this is the function where i used the post request:
void _confirm() {
if (_formKey.currentState.saveAndValidate()) {
print(_formKey.currentState.value);
var v = auth.postRequest("se_connecter", _formKey.currentState.value);
print(v);
} else {
print(_formKey.currentState.value);
print("validation failed");
}
}
Well for the second problem, i just did these changes:
void _confirm() async {
and
var v = await auth.postRequest('se_connecter', _formKey.currentState.value);
and yes it is stupid.
For the exception, it was the ssl encryption that caused it, so i removed it from my backend.
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,
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;
}
Please try passing the params as JSON encoded.
Response response = await dio.post(url, data: json.encode(params));
Hope this helps!
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.
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);
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.
i had the same error the problem come from your server. your action to the server may be get datas [FromBody] use [FromForm] it will work. for me i resolved like that
eg public DataResponseModel UpdateFormalize([FromForm] FormalizeDto dto){
//somes code
}
Recently I started developing a small application in Flutter. I have an issue with making a network request. I have tried the call in postman and there it work. But in Flutter I never managed to make it work, I have spent like 3 hours trying to understand what I am doing wrong.
Any help will be greatly appreciated.
#override
Future<String> login(common.LoginParameters loginParameters) async {
try {
final String loginURL = "https://test.example.eu/api/login";
LoginModel loginResult;
Map bodyParams = { "inlognaam" : loginParameters.username , "wachtwoord" : loginParameters.password, "code" : loginParameters.smsCode};
//await API call
http.Response httpResponse = await http.put( loginURL, body: json.encode(bodyParams));
if (httpResponse.statusCode == 200) {
// If server returns an OK response, parse the JSON
loginResult= LoginModel.fromJson(json.decode(httpResponse.body));
} else {
// If that response was not OK, throw an error.
throw Exception('Failed to load post');
}
// if logged in get token, Otherwise return error
if (loginResult.ingelogd) {
// read the token
saveToken(loginResult.response);
return "Ingelogd";
} else {
return loginResult.error;
}
}
on Exception catch(error) {
print("Todor " + error.toString());
return "Controleer uw internet verbinding en probeer opnieuw";
}
}
In Postman if I select Post request with body parameters
inlognaam : someUsername
wachtwoord : somePassword
code : someCode
Then I get a success response
I pass the parameters in the following way, maybe it can work for you:
var response = await http.post(
url,
headers:{ "Accept": "application/json" } ,
body: { "state": 1}, //key value
encoding: Encoding.getByName("utf-8")
);
Another thing, you say that in postman you make a post request, but in your code you have a put request, verify what is the correct method
I am trying to send JSON string from angular to asp.net server. I tried two things to get this data from client side.
1st : I have following code from both server and client side. I am sending a json string, and I expected to receive at backend for what I sent. However, I am just getting this server error before even getting the data.
POST "url" 404 (not found)
{"Message":"No HTTP resource was found that matches the request URI 'http://localhost:61476/api/testAPI/getData'.","MessageDetail":"No action was found on the controller 'getData' that matches the request."}
2nd : given that everything is same, i just added [FromBody] in my method like below. This doesn't return any server error and I am able to connect from my client side to server. However, I am getting my body message as null . I tried with Postman, but it seems that it works fine with Postman when I send same data.. I am aware that I can create some modelling in server code to match with my json string from client side, but I don't get why this doesn't work without modelling and also why connection fails without [FromBody].
All I need is to get JSON string from my client side. Can anyone please provide me advice on this?
public string getData([FromBody] string body)
angular
callServer(){
var json = {"name":"John Doe", "school": "A"};
let headers = new HttpHeaders();
headers.set('Content-Type', 'application/json');
this.appService.http.post('http://localhost:61476/api/testAPI/getData',
json,
{headers: headers})
.subscribe(data => {console.log(data), (err) => console.error("Failed! " + err);
})
}
server
namespace test.Controllers
{
public class testAPIController : ApiController
{
//
[HttpPost]
public string getData(string body)
{
try
{
Log.Info(string.Format("data {0}", body));
return "ok";
}
catch (Exception ex)
{
Log.Error(ex.Message);
return "error";
}
}
}}
Controller:
[HttpPost]
public string postData([FromBody]string body)
{
try
{
Log.Info(string.Format("data {0}", body));
return Json("ok");
}
catch (Exception ex)
{
Log.Error(ex.Message);
return "error";
}
}
Calling the server:
callServer() : Observable<string> {
var json = {"name":"John Doe", "school": "A"};
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
let apiUrl = 'http://localhost:61476/api/testAPI/postData';
return this.appService.http.post(`${this.apiUrl}`, json, options)
.map((res: Response) => res.json())
.catch(this.handleErrorObservable);
}
private handleErrorObservable(error: Response | any) {
console.error(error.message || error);
return Observable.throw(error.message || error);
}
Calling the service:
this._service.callServer()
.subscribe(
res => { console.log(res) },
err => { console.log(err) }
)
console.log(res/err) will be your response from the POST call. Sorry if misinterpreted your question but your question is a little hard to follow.
404 error is "not found". You must decorate your API Class
[Route("api/TestApi/[action]")]
public class testAPIController : ApiController
{
[HttpPost]
[HttpPost, ActionName("getData")]
public string getData([FromBody]string body)
{}
}
I am trying to authentiate through Google's OAuth, but I'm having problems establishing a connection to their API
My client code:
'click #addChannel': function (event) {
event.preventDefault();
var userId = Meteor.userId();
var options = {
requestPermissions: [
'https://www.googleapis.com/auth/youtube',
'https://www.googleapis.com/auth/userinfo.email',
'https://www.googleapis.com/auth/youtube.force-ssl',
'https://www.googleapis.com/auth/youtube.readonly',
'https://www.googleapis.com/auth/youtube.upload',
'https://www.googleapis.com/auth/youtubepartner',
'https://www.googleapis.com/auth/youtubepartner-channel-audit',
],
requestOfflineToken: true
};
Google.requestCredential(options, function(token) {
Meteor.call('userAddOauthCredentials', userId, token, function(error, result) {
if (error) {
throw error;
}
console.log(result);
});
});
My server code:
userAddOauthCredentials: function(userId, token) {
check(userId, String);
check(token, String);
var config = ServiceConfiguration.configurations.findOne({service: 'google'});
if (!config) {
throw new ServiceConfiguration.ConfigError();
}
console.log(token, config);
var endpoint = 'https://accounts.google.com/o/oauth2/token';
var params = {
code: token,
client_id: config.clientId,
client_secret: OAuth.openSecret(config.secret),
redirect_uri: OAuth._redirectUri('google', config),
grant_type: 'authorization_code',
};
try { <------------------------------------------------------ this fails
response = HTTP.post(endpoint, { params: params });
} catch (err) {
throw _.extend(new Error("(first) Failed to complete OAuth handshake with Google. " + err.message),
{response: err.response});
}
if (response.data.error) { // if the http response was a json object with an error attribute
throw new Error("(second) Failed to complete OAuth handshake with Google. " + response.data);
} else {
return {
accessToken: response.data.access_token,
refreshToken: response.data.refresh_token,
expiresIn: response.data.expires_in,
idToken: response.data.id_token
};
}
The above throws a [400] { "error" : "invalid_grant" } error.
Most of the above code I got from how the meteor accounts-google packages logs in a user (which works fine in my application). Link to that:
https://github.com/meteor/meteor/blob/87e3c6499d5eacce62f10faefe9ce49c77bb03ee/packages/google/google_server.js
Any advice on how to proceed from here?
Much appreciated

You have to parse your var params to application/x-www-form-urlencoded. Please find the below code to parse as i done in php
$fields_string="";
foreach($params as $key=>$value)
{
$fields_string .= $key.'='.$value.'&';
}
rtrim($fields_string, '&');
Now the $filed_string will contained the parse of params array.
