Node.js CORS：当凭据标志为真时，无法在 AccessControlAllowOrigin 中使用通配符

我有个安排

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

浏览器&lt；——webapp&lt；—— node .js(为应用服务)

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

现在，我的问题是CORS设置，webapp使用它来对后端服务器进行Ajax调用.在chrome中，我一直

当凭据标志为true时，无法在访问控制允许来源中使用通配符.

在firefox上也不起作用.

我的 node .js安装程序是:

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");
    next();
};

在Django我用的是this middleware along with this

webapp会发出如下请求:

$.ajax({
    type: "POST",
    url: 'http://localhost:8000/blah',
    data: {},
    xhrFields: {
        withCredentials: true
    },
    crossDomain: true,
    dataType: 'json',
    success: successHandler
});

因此，webapp发送的请求头如下所示:

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="***"

以下是回复标题:

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

我哪里出错了？！

编辑1:我一直在使用chrome --disable-web-security，但现在希望事情能真正起作用.

编辑2:答案:

所以，我的解决方案django-cors-headers配置:

CORS_ORIGIN_ALLOW_ALL = False
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = (
    'http://localhost:3000' # Here was the problem indeed and it has to be http://localhost:3000, not http://localhost:3000/
)
