cors

问题 Can anybody please clear up for me what the final page of the recaptcha documentation is saying, I find it exceptionally obtuse. Here's the documentation I fail to understand: Verifying the user's response This page explains how to verify a user's response to a reCAPTCHA challenge from your application's backend. When a reCAPTCHA is solved by end user, a new field (g-recaptcha-response) will be populated in HTML. You can verify the user’s response in one of three ways: g-recaptcha-response

问题 I implemented browser based resumable uploads into Google's Cloud Storage using an XMLHttpRequest send to a server-side created resumable upload url. This works completely fine when disabling web security, which I did during development. But now in the real world, CORS keeps making trouble. I tried this with other browsers (without success), too, but sticked to chrome for further testing. Note: A fake.host entry in /etc/HOSTS is used to trick chrome into avoiding localhost-restrictions.

问题 I have a Rails service returning data for my AngularJS frontend application. The service is configured to allow CORS requests by returning the adequate headers. When I make a GET request to receive data, the CORS headers are sent, as well as the session cookie that I have previously received on login, you can see for yourself: Request URL:http://10.211.194.121:3000/valoradores Request Method:GET Status Code:200 OK Request Headers Accept:application/json, text/plain, */* Accept-Encoding:gzip

问题 I'm hosting some JSON files on Github pages, but I am unable to use $.getJSON to retrieve them unless they come from the exact same domain. Is there a way to enable CORS for Github pages? 回答1: As a workaround one can use JSONP, but it's still slightly a pain because the files are static, and each one will need a unique callback method. Another alternative would be to store the files in Gists and use the Github API which works with CORS. A third possibility is to not store the files on Github

问题 Does anyone know if Safari supports crossorigin attribute on the HTML5 <video> tag? I serve video from a server that responds with all needed CORS headers, and I use the markup below to embed the video to my page. The page is served from a different domain. <video controls crossorigin="anonymous" src="http://example.com/movie.mp4"> I then draw the video to a canvas and get the image from the canvas using toDataURL API. This works in Chrome and Firefox, but Safari throws the security error as

问题 I have a page loading up in MobileSafari which communicated with another server via CORS. In desktop browsers (tested Chrome and Safari), I am able to log in, get a session cookie, and have that session cookie be sent back for subsequent requests so that I may be authenticated with all API calls. However, when I login via Mobile Safari, the cookie does not get sent back on subsequent requests. I'm using Charles Proxy to spy on what's going on, and it tells me: POST https://myremoteserver.com

问题 I try to set an Authorization header to a GET request to authenticate users to a rest API. I'm using Angular 2 RC1. (I'am a total beginner). getTest(){ let authToken = localStorage.getItem('auth_token'); let headers = new Headers({ 'Content-Type': 'application/json' }); headers.append('Authorization', `Bearer ${authToken}`); let options = new RequestOptions({ headers: headers }); return this._http .get(this._url,options) .map(res => console.log(res)); } I allow CORS in my backend. header(

问题 Got this error message: Refused to set unsafe header "Origin" Using this code: function getResponse() { document.getElementById("_receivedMsgLabel").innerHTML += "getResponse() called.<br/>"; if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { receiveReq.open("GET", "http://L45723:1802", true, "server", "server123"); //must use L45723:1802 at work. receiveReq.onreadystatechange = handleReceiveMessage; receiveReq.setRequestHeader("Origin", "http://localhost/"); receiveReq

问题 I know there are a lot of questions concerning CORS already but they don't seem to answer my question. So I have a client app written in Angular which will be used to create a mobile app (with Apache Cordova). The html files and JavaScript files will be loaded from the mobile device. When I simulate that and I send requests to the REST API server I first got "No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://localhost:82 ' is therefore not allowed

问题 I've been struggling recently with a super-weird problem only happening in Chrome: as my API (NodeJS) is on a different subdomain, I need to use CORS to reach it from my front-end (EmberJS). It's working pretty well but I'm very frequently (95% of the time) having very very slow OPTIONS queries, delaying any API calls by about 3 seconds. Most of this time is spent downloading an empty content: It gets even weirder when I'm trying this on another website we made using a similar architecture,
