跨域产生的原因,什么是跨域,如何解决跨域,可以参考阮一峰写的博文:http://www.ruanyifeng.com/blog/2016/04/cors.html
打开chrome浏览器,F12打开console控制台,可以在里面写xml http request代码了。 如图,发送简单请求给不允许跨域的服务器(对于这种简单请求浏览器不会发送预检请求,而是直接发送真正的请求)。可以再修改请求来模拟非简单请求。
可以参考代码 https://github.com/rs/cors 具体流程是判断跨域请求是否是预检请求,如果是预检请求,则处理预检请求,否则处理实际请求。 if r.Method == "OPTIONS" && r.Header.Get("Access-Control-Request-Method") != "" { c.logf("HandlerFunc: Preflight request") c.handlePreflight(w, r) } else { c.logf("HandlerFunc: Actual request") c.handleActualRequest(w, r) }
if r.Method == "OPTIONS" && r.Header.Get("Access-Control-Request-Method") != "" { c.logf("HandlerFunc: Preflight request") c.handlePreflight(w, r) } else { c.logf("HandlerFunc: Actual request") c.handleActualRequest(w, r) }
