CORS 详解

CORS是一个W3C标准,全称是"跨域资源共享"(Cross-origin resource sharing)。 它允许浏览器向跨源服务器,发出 XMLHttpRequest 请求,从而克服了AJAX只能 同源 使用的限制。 本文详细介绍CORS的内部机制。 一、简介 CORS需要浏览器和服务器同时支持。目前,所有浏览器都支持该功能,IE浏览器不能低于IE10。 整个CORS通信过程,都是浏览器自动完成,不需要用户参与。对于开发者来说,CORS通信与同源的AJAX通信没有差别,代码完全一样。浏览器一旦发现AJAX请求跨源,就会自动添加一些附加的头信息,有时还会多出一次附加的请求,但用户不会有感觉。 因此,实现CORS通信的关键是服务器。只要服务器实现了CORS接口,就可以跨源通信。 二、两种请求 浏览器将CORS请求分成两类:简单请求(simple request)和非简单请求(not-so-simple request)。 只要同时满足以下两大条件,就属于简单请求。 (1) 请求方法是以下三种方法之一: HEAD GET POST (2)HTTP的头信息不超出以下几种字段: Accept Accept-Language Content-Language Last-Event-ID Content-Type:只限于三个值 application/x-www-form

问题 I'm using rackspace to host my image files that are drawn on an html5 canvas object. Because of an HTML security feature when saving a canvas I have to use CORS (Cross Origin Resource Headers) to make save work.

问题 How do I allow multiple domains for CORS in express in a simplified way. I have cors: { origin: "www.one.com"; } app.all('*', function(req, res, next) { res.header("Access-Control-Allow-Origin", cors.origin); res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept"); next(); }); This works when there is only one domain mentioned in origin But if I want to have origin as an array of domains and I want to allow CORS for all the domains in the origin array, I
