1.情景展示 ajax调取java服务器请求报错 报错信息如下: 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. 但是,请求状态却是成功:200,这是怎么回事? 2.原因分析 ajax请求跨域:ajax出现请求跨域错误问题是因为浏览器的“同源策略”. 同源策略:1995年,同源政策由 Netscap…
今天做一个AJAX案例时,浏览器监控到如下错误: XMLHttpRequest cannot load http://54.169.69.60:8081/process_message. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://54.169.69.60' is therefore not allowed access. 网站地址是 http://54.…
默认情况下ajax请求是有同源策略,限制了不同域请求的响应. 例子:http://localhost:23160/HtmlPage.html 请求不同源API http://localhost:22852/api/values, What is "Same Origin"? Two URLs have the same origin if they have identical schemes, hosts, and ports. (RFC 6454) These two URLs h…

用angular发起http.get(),访问后端web API要数据,结果chrome报错:跨域了 Access to XMLHttpRequest at 'http://127.0.0.1:3000/XXX' from origin 'http://127.0.0.1:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resour…
花了一个上午来追踪问题,k8s都反复新建了十多次,docker都重启了几次.(一次显示不有获取磁盘空间,重启docker,清空存储解决) 在用kubeadm安装容器化的几个组件时,flannel组件死活不能启动,报如下问题: Failed to create SubnetManager: error retrieving pod spec for 'kube-system/kube-flannel-ds-xxx': the server does not allow access to the…
最近在使用GeoServer调用Vector Tile服务时,经常会显示不出来结果.打开浏览器调试台,发现报No 'Access-Control-Allow-Origin' header is present on the requested resource这个错误.主要原因是不能跨域访问.例如服务器上有两个服务A和B,A的端口是6000,B的端口是6001,则A不能直接调用B的端口.为了解决这个问题,通过上网查找资料,特别是Tomcat的官方文档,最后总结出两种解决方案. 方案一:安装chr…

使用 android_uiautomator 定位元素时(现在用的还不太熟,对于这个方法还需要加深了解)报错: 报错信息:The requested resource could not be found, or a request was received using an HTTP method that is not supported by the mapped resource 因为用的不熟,所以也是上网查了好多方法,最后检查代码的时候发现,原来是拼写错误 我将new UiSelect…
