IdentityServer3 ResourceOwner Angular请求返回400错误请求

Question

I have an identityServer3 example application.

public static IEnumerable<Client> GetClients()
        {
            return new[]
                   {
                       new Client
                       {
                           Enabled = true,
                           ClientId = "manager",
                           ClientName = "ManagerIdentity",
                           Flow = Flows.ResourceOwner,
                           ClientSecrets = new List<Secret>
                           {
                               new Secret("secret".Sha256())
                           },
                           AllowedScopes = new List<string>
                           {
                               Constants.StandardScopes.OpenId
                           },
                           AllowAccessTokensViaBrowser = true,
                           AllowedCorsOrigins = new  List<string>{ 
                              "http://localhost:24678/" // angular application uri
                           }
                       }  
            }

I am using this informations and request by Postman and token returns.

But I send same request via angularjs javascript application it returns 400 bad request.

angular.module("app").controller("ROPCController", [
    "$scope","$http",
    function($scope,$http) {

        $scope.login = function() {


            var options = {
                "url": "http://localhost:4751/connect/token",
                "method": "POST",
                "data": {
                    "username": "muser",
                    "password": "password",
                    "grant_type": "password",
                    "client_id": "manager",
                    "client_secret": "secret",
                    "scope":"openid"
                },
                "headers": {
                     "Content-Type": "application/x-www-form-urlencoded"
                }
            };

            $http(options).then(
                function(response) {
                    console.log(response.data);
                },
                function(error) {
                    console.log(error);
                }
            );
        }
    }
]);

{"error":"invalid_client"}

Answer 1

Your data is in json format so your should change the content-type to application/json or change the format of your data to username=muser&password=password&...

Hope this helps.
