问题 I am trying to develop a frontend application using Angular. Since I added the authorization header to the HTTP POST and GET requests, I'm getting 405 Method Not Allowed , although I seemingly allow everything on the server side. The debugger in my browser Chrome says it's asking for Access-Control-Request-Method: POST and Access-Control-Request-Headers: authorization , my backend allows both, access-control-allow-methods: GET, POST and access-control-allow-headers: authorization , as well as

问题 (continuation of error message in title) " Origin 'http://127.0.0.1:4200' is therefore not allowed access." I am unable to run the same Angular 5 site on two different domains when working with the same API. This error message is coming from Chrome. The error in Firefox is: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://myapitest.local/v1/subscription/current/products. (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match ‘http

问题 I am attempting to create an audio visualization program on Codepen. I have created my own Ubuntu web server with apache which allows me direct access to modify headers and configuration of the server. While browsers can access files on a different domain, it requires special CORS headers to read the frequencies within the audio. To read audio frequencies, I must use createMediaElementSource to access audio information including the frequencies. When the browser sees this JavaScript method,

问题 SOLUTION: Add a trailing slash to the end of the url... "http://127.0.0.1:8000/xyz/api/abc/" instead of "http://127.0.0.1:8000/xyz/api/abc" .... I have successfully created a Django Rest API and am able to store and host data locally it seems. I have built an angularjs1.0 app separately and am attempting to extract the data via $http get request however I'm running into this error: XMLHttpRequest cannot load http://127.0.0.1:8000/xyz/api/abc. No 'Access-Control-Allow-Origin' header is present

问题 This is in the context of Cross-origin resource sharing. For the preflight request, the server is not sending the headers set. When a valid cookie is not passed with the "Options request", the server in it's response is not sending the headers I set, however, it's sending "200 OK". I checked this with curl as can be seen below (obviously, I replaced my valid cookie with a dummy "xyzabcde" here) The curl request WITHOUT cookie: curl -H "Origin: app2_url" -H "Access-Control-Request-Method: POST

问题 I have a simple GWT application running from IIS on my server. I am trying to test HTTP requests to tomcat running on the same server. However, since both the application servers are running on different ports, my browser (chrome and firefox) treats the requests as a CORS request. To enable tomcat to accept CORS request, I updated it to Tomcat 7.0.52 and enabled the CORS filter in the global web.xml configuration. I tested this simple setup and it seems to work. Here is the code in GWT:

问题 I create a RESTful API with Spring boot and host it in Pivotal web services . Let's say the url is https://abc.cfapps.io/students and the json result will be [ {"id":1,"name":"Michael","score":8.5}, {"id":2,"name":"Naomi","score":5.6} ] Then I write an Angular client to send a request to that url: angular.module("app", []).controller("listController", function($scope, $http) { var url = 'https://abc.cfapps.io/students'; var httpRequest = new XMLHttpRequest(); httpRequest.open('GET', url, true

问题 Recently we moved our assets on a CDN Cloudfront. We have noticed that the surfaces were broken on Firefox. After a few minutes of searching, it was a story of CORS. We allowed the field Cloudfront. application_controller : after_filter :set_access_control_headers def set_access_control_headers headers['Access-Control-Allow-Origin'] = CDN_CLOUDFRONT end production.rb : CDN_CLOUDFRONT = "http://xxx.cloudfront.net" This worked very well until yesterday. After several searches and reflections, I
