【原创】OPTIONS请求之跨域请求被阻止（原因：CORS预检通道未成功）解决方案 超神！牛逼！

问题详情

Stackoverflow：OPTIONS请求跨域问题https://stackoverflow.com/questions/72465838/why-does-this-cors-preflight-did-not-succeed-always-appear-resulting-in-the-use/72470620#72470620

代码参考

      if(request.getMethod().equals(RequestMethod.OPTIONS.name()))
        {
            response.setHeader("Access-Control-Allow-Origin","*");
            response.setHeader("Access-Control-Allow-Headers","*");
            response.setHeader("Access-Control-Allow-Methods","*");
            response.setHeader("Access-Control-Allow-Credentials","true");
            response.setHeader("Access-Control-Max-Age","3600");
            response.setStatus(HttpStatus.OK.value());

            return true;
        }

问题解决

• 之前尝试在拦截器方法内添加此代码块  无效

      if(request.getMethod().equals(RequestMethod.OPTIONS.name()))
        {
            return true;
        }

• 然后发现需要在此代码块内添加跨域Head信息 成功

   if(request.getMethod().equals(RequestMethod.OPTIONS.name()))
        {
            response.setHeader("Access-Control-Allow-Origin","*");
            response.setHeader("Access-Control-Allow-Headers","*");
            response.setHeader("Access-Control-Allow-Methods","*");
            response.setHeader("Access-Control-Allow-Credentials","true");
            response.setHeader("Access-Control-Max-Age","3600");
            response.setStatus(HttpStatus.OK.value());

            return true;
        }
