Dart request succeeding ... somehow? -

i'm developing dart application consume rest service i'm building. started writing out dart code perform ajax request login endpoint. however, when dart ajax request should fail, claims succeed.

i don't have services , running (and if did using wrong domain / port right now), code gives 200 ok httpresponse every time:

class playercontroller {    const playercontroller();    static const string login_url = "login";    void login(string username, string password) {     map<string, string> headers = {"content-type": "application/x-www-form-urlencoded"};     string body = "j_username=$username&j_password=$password&submit=login";     httprequest.request(login_url, method: "post", requestheaders: headers, senddata: body)       .then((request) => processlogin(request, username))       .catcherror((e) => processloginerror(e));   }    void processlogin(var whatisthis, string username) {     query("#loginbutton").text = "logout";     //todo player set them   }    void processloginerror(var e) {     print("total failure login because of $e");   } } 

it hits processlogin method, , never hits processloginerror method. have idea why be? should performing ajax request in different way? (if couldn't guess, signing spring security).

i read somewhere file system requests succeed. dart somehow making file system request rather web request?

this because request completes successfully.

your request "login" call http://127.0.0.1:6521/[path_to_your_dart_file]/login

the server started dart when running in dartium (127.0.0.1:6521) seems answer every post request http 200 , empty response body.

if change method post get, fail expected.

as why server - don't know. have answered dart team.
