Node js / Angular js - CAUTION: Provisional headers are shown
angularjs, http-headers, javascript, node.js, xmlhttprequest
Solution
personaly I use this "reset" method in angular:
app.config(['$httpProvider', function ($httpProvider) {
//Reset headers to avoid OPTIONS request (aka preflight)
$httpProvider.defaults.headers.common = {};
$httpProvider.defaults.headers.post = {};
$httpProvider.defaults.headers.put = {};
$httpProvider.defaults.headers.patch = {};
}]);
Problem
This is my Angular js piece code: ``` $http({ method:'POST', withCredential:true, url:$scope.config.app_ws+'auth/signup', data:{user:$scope.auth} }).success(function(status, response){ console.log(response); }).error(function(status, response){ alert(response+'Bummer :( , an error occured plese retry later. '); }); ``` This is my Node.js piece backend: ``` var allow_cross_domain= function(req, res, next) { res.header('X-Powered-By', 'hey.heyssssssss.org'); var oneof = false; if(req.headers.origin) { res.header('Access-Control-Allow-Origin', req.headers.origin); oneof = true; } if(req.headers['access-control-request-method']) { res.header('Access-Control-Allow-Methods', req.headers['access-control-request-method']); oneof = true; } if(req.headers['access-control-request-headers']) { res.header('Access-Control-Allow-Headers', req.headers['access-control-request-headers']); oneof = true; } if(oneof) { res.header('Access-Control-Max-Age', 60 * 60 * 24 * 365); } // intercept OPTIONS method if (oneof && req.method == 'OPTIONS') { res.send(200); } else { next(); } } app.use(allow_cross_domain); app.post('/auth/signup', function (req, res) { res.send('wtff'); }); ``` I'm just calling POST localhost:3000/auth/signup from Angular to Node, but i get `**CAUTION : Provisional headers are shown.**` in chrome console. Chrome (CAUTION): Firefox (NO RESPONSE for about 30/60 seconds and then the alert() comes up :/ ): what this could be? IF i use GET everything is ok, is just with POST that i get troubles how is that possible?
