cors

问题 I am working on a php and angular 6 based single page application.

问题 I'd like to POST data to another domain and receive the confirmation message returned by the action. So to get CORS to work I've got an options action to handle the OPTION HTTP method (on the same path as the POST) in my rails controller, which currently looks like this: def options headers['Access-Control-Allow-Origin'] = "*" headers['Access-Control-Allow-Methods'] = 'GET, POST, PUT, OPTIONS' headers['Access-Control-Max-Age'] = '100' headers['Access-Control-Allow-Headers'] = '*, x-requested

问题 I am using, for the first time, angularJs and I would do a thing very simple, but I don't know what I wrong.

I created this simple API: http://www.mocky.io/v2/5a1fedce310000221bc0b08b that return: {"id" : 1, "name" : "France - Mainland", "desc": "some description" }, {"id" : 2, "name" : "Gibraltar", "desc": "some description"}, {"id" : 3, "name" : "Malta", "desc": "some description"} Now I have my

问题 So this is the first time I build a website in Full and my own, including front-end, back-end and database. I'm using the ZURB Foundation Framework (ZURB Template) which makes the project modular using Webpack4, Babel7 and Gulp (Taskrunner). Ive downloaded the latest portable XAMPP distribution for windows and run apache from it. So far, I definitely CAN get my backend to interact with my front-end.

问题 I've recently started delegating to a CDN-hosted jquery, forgetting about my ajax calls being impacted by CORS -- oops. Surprisingly, we haven't seen browsers making much fuss about it! Specifically, as far as we can tell only one particular browser does a preflight OPTIONS (the agent is "Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0"). Vast majority of browsers out there, including Chrome, FF or Safari are perfectly happy without the preflight -- one of the reasons why we didn't

问题 I'm trying to access a node route through angular $http using the cors module. I've tried a simple app.use(cors()); but still get the error. And I've tried adding from the cors documentation a whitelist of URLs var corsOptions = { origin: function(origin, callback){ var originIsWhitelisted = whitelist.indexOf(origin) !== -1; callback(null, originIsWhitelisted); } }; app.get('/someroute/:someparam/', cors(corsOptions), function(req, res, next){ mymodule.getData(req.params.someparam, function
