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(为应用提供服务)
浏览器(webapp)-> Ajax-> Django(服务ajax POST请求)
现在,我的问题是CORS设置,Web应用程序使用它来对后端服务器进行Ajax调用。在Chrome中,我不断
当凭据标志为true时,不能在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();
};
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
我要去哪里错了?
编辑1:我一直在使用chrome --disable-web-security
,但是现在希望事情能够实际进行。
编辑2:答案:
因此,为我解决的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/
)
http
,而是/
末尾。我想省略http可以工作,但是几年来我一直没有真正从事过这项工作,所以现在真的不知道什么可行!
