问题 I recieve an error (XMLHttpRequest cannot load https:// www.cloudflare.com/api_json.html?tkn=&email=&z=&a=rec_load_all&callback=%3F. Origin http:// domainmanager.tech-bytes.org is not allowed by Access-Control-Allow-Origin.)

The CloudFlare API states that you can ask for a JSONP callback by appending a &callback=mycallback parameter . I am not sure if I am supposed to

问题 I have a web service which works over GET . To access this web service, some custom headers need to be passed. When I try to access the web service from javascript code with GET method, the request method is getting changed to OPTIONS . (the domain is different) I read some articles to find out that a request with Custom headers will be pre-flighted and in that case before the actual method call, a request with OPTIONS method will be made to the server. But my problem is after the OPTIONS

问题 I'm running a meteor app, which I just deployed to production with Meteor up. Now I have a mismatch when I try to login using a Oauth service between example.com and www.example.com. In my fb-app I use the www address. So if I go to example.com and try to login, I get an error in console about same-origin-policy. I'm using the browserpolicy package for Meteor. In which I added both non-www and www inside BrowserPolicy.content.allowOriginForAll(origin); What's the correct fix for this? Can I

问题 I've read this question about how third party cookie are set , which is a subject I already know : it can be done via three ways : Script ( application/javascript )mime type ( which is generated at server side) which can also set cookie. ( along with the script response). img link <IMG href="http://www.advertiser.exmaple/add.cgi?source=example.com&user=1032354"> form submission to an iframe ( for safari) Also , this answer explain it pretty well.

问题 I am trying to design a web page (PHP) that extracts certain elements loaded up by and external website and displays it in my own format on my website. I have seen many things regarding this, but they all seem to work with a the Same Site Origin Policy only. Another issue is that the first element loaded is a text input that needs to be submitted in order to load up what I'm ultimately trying to retrieve, so how can I got about putting this in my page aswell? Example of layout: Notice that

问题 It is a good security standard, I'd say, it stops websites from loading shady stuff from other websites on your browser. However, when developing, it's complete hell for any application that uses AJAX (that includes LESS, W3Data and Web Components polyfill, to name a few), since the browser thinks I'm calling from outside (since there's no server). I know that you can disable browser security, but that has two problems: first, if I'm correct, it disables any kind of security Chrome offers and

问题 How is it possible that when I try to make an XMLHTTPRequest from a javascript file to a web service located on the very same domain, I get: Origin http://mydomain.com is not allowed by Access-Control-Allow-Origin ??? If I change mydomain.com to localhost, I no longer have problems, but I would like to keep it as mydomain.com What do I have to edit, and why in the first place, since it's the same domain? 回答1: 1) look in your request/response headers. Is the server returning a weird access

问题 I'd like to make a web service call from http: //www.somedomain.com to https ://www.somedomain.com Without going to the trouble of setting up a test, could someone confirm if this will be considered the same origin? My assumption is that this will be fine, seeing as cookies are shared successfully in this situation. 回答1: No, it wont work the url needs the same domain and the same protocol see http://en.wikipedia.org/wiki/Same_origin_policy 回答2: No, it is not same origin. Perhaps you can

问题 (and if not, does it actually improve client side security?) I'm thinking of the case where a script from server X uses XHR to obtain and run untrusted code from server Y (which supports CORS). (obviously evaluating untrusted code is bad™) 回答1: I do not use CORS to improve security at all. I use CORS to access a known webservice on a different domain which I would not be allowed to access without CORS. Nothing to do with improving security in my opinion, but to allow data from one domain to
