Question

我是java脚本和CORS的新手，现在已经坚持了一段时间。我做了很多阅读但没有运气。客户端在浏览器（Chrome / Firefox）中运行并发出导致OPTION和PUT请求的PUT请求。服务器将PUT请求重定向到另一台服务器。以下是基于java脚本的客户端和基于java的服务器之间的HTTP通信捕获：

选项请求：

Host: 10.232.65.230:8000
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0

Origin: http://10.232.65.230:3001
Access-Control-Request-Method: PUT

OPTION回复：

Access-Control-Allow-Headers: content-type
Access-Control-Allow-Methods: PUT

PUT请求：

PUT回复：

Location: http://10.232.65.230:8000/edge/ermsim/erms/1/edgedevices/1/config/edgeinputs/1
Server: Apache-Coyote/1.1

但是，不是重定向到提供的位置，浏览器抛出以下错误：

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://10.232.65.230:8000/ermsim/erms/1/edgedevices/1/config/edgeinputs/1. This can be fixed by moving the resource to the same domain or enabling CORS.

我将不胜感激任何帮助！

Answer 1

您发送的返回码是否不等于200？

响应的HTTP状态代码不在2xx范围内


应用网络错误步骤。

CORS对代码2xx的限制为：http://www.w3.org/TR/cors/#cross-origin-request-with-preflight-0

服务器返回CORS头，浏览器仍然抛出跨源请求阻止错误
