问题 I am trying to get an OAuth2 Token via XHR-Request in TypeScript like mentioned on this side(https://developer.paypal.com/docs/integration/direct/make-your-first-call/). My code so far: var clientID = <clientID>; var secret = <mySecret>; var oReq = new XMLHttpRequest(); oReq.open("POST", "https://api.sandbox.paypal.com/v1/oauth2/token", true); oReq.setRequestHeader('grant_type', "client_credentials"); oReq.setRequestHeader('Username', this.clientID); oReq.setRequestHeader('Password', this

问题 I have a Rails App hosted on Heroku which is using CloudFront with assets hosted on S3. It displays assets prefectly(although it took some wrestling). My setup for Cloudfront: Forward Headers: Whitelist Whitelist Headers: Origin Forward Query Strings: No CORS setup for the S3 bucket: <?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <AllowedMethod>HEAD<

问题 I am trying to POST a search request from a jQuery/knockout web app. I followed the directions for implementing CORS in WCF and also added the following to the service: [OperationContract] [WebInvoke(Method = "OPTIONS", UriTemplate = "*")] public void GetOptions() { } The search request works fine in Chrome and Firefox. Chrome sends an OPTIONS request, which is handled successfully ( 200 ) and the access-control headers are in the response, and then it sends the POST , which returns search

问题 I am encounter a strange problem. I have a Asp.net Core WebApi project running under Azure App Service (Website). I am using DHC plug-in in Chrome. My service is also running with AAD. I can request a GET method just fine (After login). However, when I request any POST, I got a 403 response. Looking around in the log, I can see this 2016-07-28T08:14:26 PID[x] Verbose Received request: POST https://blahblah.azurewebsites.net/api/build/beep/ 2016-07-28T08:14:26 PID[x] Verbose Found

问题 The server answer with a Access-Control-Allow-Origin value set for the production. Is there a way to be permissive when the requests come from my development server ? Is there a Django setting to disable the cross-origin check when DEBUG=True for example ? I can't modify the Access-Control-Allow-Origin . The request is made with jquery ajax function. EDIT: I've installed https://github.com/ottoyiu/django-cors-headers with pip install django-cors-headers , added the following in my settings.py

问题 I'm trying to grab an image from Amazon S3 using cross-origin resource sharing so that I can use the canvas.toDataUrl() method. On S3 I set the CORSconfiguration on the bucket to: <?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <AllowedMethod>POST</AllowedMethod> <AllowedMethod>PUT</AllowedMethod> <MaxAgeSeconds>3000</MaxAgeSeconds> <AllowedHeader>*<

问题 When I use the Uber API, with localhost I receive the following error: ... No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. So maybe I made an error. To test, I tried the url in Postman, but everything works as expected; I receive the expected JSON data. I also tried with curl. It works as expected. I am sending my server token and I've adjusted my headers. No luck. Previous SO answers hinted at this

问题 I have relaunched my website with Wordpress. Unfortunately, a couple of fonts are not being displayed neither in Chrome nor Firefox nor IE. I get the following error: Access to Font at 'MY WORDPRESS FONTS URL' from origin 'http://w8qb4xj6s.homepage.t-online.de' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.obstgut-auf-der-heide.de' is therefore not allowed access. This is probably because I've installed

问题 My server sends custom headers along with the response. I get the response data alright, but I can't access the custom headers with jQuery's getAllResponseHeaders() or AngularJS $http service. All I get is content-type . When I inspect the request response with DevTools or fiddler, I can see all the custom headers being sent by the server, but I can't get them from xhr. Is there any way to access all the headers? 回答1: OK I got this working after adding allowed headers in my server config
