我有一个涉及的设置
前端服务器(Node.js,域:localhost:3000)<---> 后端(Django,Ajax,域:localhost:8000)
浏览器 <-- webapp <-- Node.js(服务应用程序)
浏览器 (webapp) --> Ajax --> Django(服务 ajax POST 请求)
现在,我的问题是 webapp 用于对后端服务器进行 Ajax 调用的 CORS 设置。在 chrome 中,我不断得到
当凭证标志为真时,不能在 Access-Control-Allow-Origin 中使用通配符。
也不适用于Firefox。
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();
};
webapp 发出这样的请求:
$.ajax({
type: "POST",
url: 'http://localhost:8000/blah',
data: {},
xhrFields: {
withCredentials: true
},
crossDomain: true,
dataType: 'json',
success: successHandler
});
因此,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: en-US,en;q=0.8
Cookie: csrftoken=***; sessionid="***"
这是响应标头:
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
我哪里错了?!
编辑1:我一直在使用chrome --disable-web-security
,但现在希望事情能够真正起作用。
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/
)
