Angular.js $http intercept "net::ERR_CONNECTION_REFUSED"
angularjs, http, interceptor, javascript
Solution
You can probably check the status of the ResponseError. When an API is offline that is 0 (until Angular 1.3.18) or -1 (since Angular 1.3.19):
angular.module("services.interceptor", arguments).config(function($httpProvider) {
$httpProvider.interceptors.push(function($q) {
return {
responseError: function(rejection) {
if(rejection.status <= 0) {
window.location = "noresponse.html";
return;
}
return $q.reject(rejection);
}
};
});
});
Problem
I'm trying to write a generic error handler for my website using `$http'`s interceptors but they don't seem to be able to do what I want to do. I placed interceptors on `'response'` and `'responseError'` but they never get called when the server is offline/not reponding (net::ERR_CONNECTION_REFUSED). I understand why this happens, there's no response to intercept. I'd like to know if there's a generic way of catching these errors, other than listening to the `$httpPromise`'s `error` callback for each request.
