相关疑难解决方法(0)

我有一个涉及的设置

前端服务器(Node.js,domain:localhost:3000)<--->后端(Django,Ajax,域:localhost:8000)

浏览器< - webapp < - Node.js(服务应用)

浏览器(webapp) - > Ajax - > Django(服务ajax POST请求)

现在,我的问题在于CORS设置,webapp使用它来向后端服务器进行Ajax调用.在chrome中,我一直在努力

当credentials标志为true时,无法在Access-Control-Allow-Origin中使用通配符.

在Firefox上也不起作用.

我的Node.js设置是:

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();
};

而在Django我使用这个中间件 与此相伴

webapp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发送的请求标头如下所示:

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: …
