Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true.
在火狐浏览器上也不行。
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();
};
在Django中,我使用这个[中间件](https://gist.github.com/strogonoff/1369619 ""),同时使用webapp这样的请求:
$.ajax({
type: "POST",
url: 'http://localhost:8000/blah',
data: {},
xhrFields: {
withCredentials: true
},
crossDomain: true,
dataType: 'json',
success: successHandler
});
因此,Web应用程序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="***"
下面是响应头:
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
哪里出问题了?!
---我尝试使用: chrome --disable-web-security
, 但没有让其真正运作起来。
所以,我最终的解决方案是: django-cors-headers
条目:
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/
)
