cors

问题 I have set up a node server with socket io turning and trying to connect to it through another server. However some browsers on different computers give me this error and makes it reconnect the whole time: XMLHttpRequest cannot load https://serverDomain.net:3000/socket.io/?EIO=3&transport=polling&t=Lo_SdiU. The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'https://www

问题 First, let me say that I have tried a ton of solutions that have been posted here. None of them seem to work for me. I realize that my problem is stemming from CORS and my rails app's inability to handle the correctly. However, I'm not quite sure how to rectify this issue. I'm hoping someone here can shed some light on this issue. Relevant Code snippets: Rails application_controler.rb class ApplicationController < ActionController::Base protect_from_forgery #before_filter :cors_preflight

问题 I'm trying to set the 'Access-Control-Allow-Origin: *' header for the response. However, the header is not present. What am I doing wrong? public class JsonApplication extends Application { private static final String SERVER_URL = "http://localhost:8111"; public static void main(String[] args) throws Exception { Server testServer = new Server(Protocol.HTTP, 8111); JsonApplication jsonApplication = new JsonApplication(); CorsService corsService = new CorsService(); corsService

问题 My Vertx Server resides in server A and client resides in server B. When i tried to access vertx server, CORS error pops in. I added some server side code to handle CORS issue but it's not working. Do we need to add some header in client side. what am i missing here? Can anyone help Vertx Server Side: Router router = Router.router(vertx); router.route().handler(BodyHandler.create()); router.route().handler(io.vertx.rxjava.ext.web.handler.CorsHandler.create("*") .allowedMethod(io.vertx.core

问题 When I send a POST request to the server I get an error: Failed to load http://localhost:8181/test: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 403. The backend is written in Java Spring. My method for creating a test: createTest() { const body = JSON.stringify({ 'description': 'grtogjoritjhio',

问题 The Issue I'm Having I'm making an Ajax POST request from my Angular2 client to my Django (v1.9) backend (both on localhost, different ports). I'm not yet using the Django REST framework, I'm just dumping the JSON in Django without any add-ons. I have been issued a csrf token by the server, and I'm manually sending it back in the HTTP headers (I can see it there when I make the call). However, I still get the error from django: Forbidden (CSRF cookie not set.) I've read a number of other

问题 Looking at the new fetch API, you can specificy a mode field in the request. From Mozilla: The mode read-only property of the Request interface contains the mode of the request (e.g., cors, no-cors, same-origin, or navigate.) This is used to determine if cross-origin requests lead to valid responses, and which properties of the response are readable. And then how to use it: var myHeaders = new Headers(); var myInit = { method: 'GET', headers: myHeaders, mode: 'cors', cache: 'default' }; fetch

问题 While working on a project to make our site HTML 5 friendly, we were eager to embrace the new method for Cross Domain requests (no more posting through hidden iframes!!!). Using the Access Control specification we begin setting up some tests to verify the behaviour of various browsers. The current Rails RESTful architecture relies on the four HTTP verbs: GET, POST, PUT, DELETE. However in the Access Control spec, it dictates that non-simple methods (PUT, DELETE) require a pre-flight request

问题 I have two servers (Apache and JBoss AS7) and I need to provide access to all http methods to a client. All these request must be sent via ajax. Example of the client code: $.ajax({ type: "get", url: "http://localhost:9080/myproject/services/mobile/list", crossDomain: true, cache: false, dataType: "json", success: function(response) { console.log(response); }, error: function (jqXHR, textStatus, errorThrown) { console.log(textStatus); console.log(jqXHR.responseText); console.log(errorThrown);
