Cors: 当凭据标志为真时,不能在 Access-Control-Allow-Origin 使用通配符

  • node.js
  • django
  • cors
  • ajax

I have a setup involving

Frontend server (Node.js, domain: localhost:3000) <---> Backend (Django, Ajax, domain: localhost:8000)

Browser <-- webapp <-- Node.js (Serve the app)

Browser (webapp) --> Ajax --> Django(Serve ajax POST requests)

Now, my problem here is with CORS setup which the webapp uses to make Ajax calls to the backend server. In chrome, I keep getting

Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true.

doesn't work on firefox either.

My Node.js setup is:

var allowCrossDomain = function(req, res, next) {
    res.header('Access-Control-Allow-Origin', 'http://localhost:8000/');
    res.header('Access-Control-Allow-Credentials', true);
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

And in Django I'm using this middleware along with this

The webapp makes requests as such:

    type: "POST",
    url: 'http://localhost:8000/blah',
    data: {},
    xhrFields: {
        withCredentials: true
    crossDomain: true,
    dataType: 'json',
    success: successHandler

So, the request headers that the webapp sends looks like:

Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: "Origin, X-Requested-With, Content-Type, Accept"
Access-Control-Allow-Methods: 'GET,PUT,POST,DELETE'
Content-Type: application/json 
Accept: */*
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Cookie: csrftoken=***; sessionid="***"

And here's the response header:

Access-Control-Allow-Headers: Content-Type,*
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST,GET,OPTIONS,PUT,DELETE
Content-Type: application/json

Where am I going wrong?!

Edit 1: I've been using chrome --disable-web-security, but now want things to actually work.

Edit 2: Answer:

So, solution for me django-cors-headers config:

    'http://localhost:3000' # Here was the problem indeed and it has to be http://localhost:3000, not http://localhost:3000/
