不支持请求方法类型:ATG中的选项

Question

im在使用请求方法帖子进行API调用时遇到问题。飞行前选项方法正在失败。我正在Weblogic 12c上运行ATG。以下是我的CORS代码

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import atg.servlet.*;
import atg.servlet.pipeline.*;
public class CORSHeaderServlet extends InsertableServletImpl{
  public CORSHeaderServlet () {}
  public void service (DynamoHttpServletRequest request,
                       DynamoHttpServletResponse response)
       throws IOException, ServletException
  {
     //add headers to response.
    response.addHeader("Access-Control-Allow-Origin" ,"*");
    response.addHeader("Access-Control-Allow-Methods", "GET, POST, PATCH, PUT, DELETE, OPTIONS");
    response.addHeader("Access-Control-Allow-Headers","Origin, Content-Type, X-Auth-Token, X-PINGOTHER");
    response.addHeader("Access-Control-Max-Age", "86000");
    passRequest (request, response);
  }
}

浏览器错误是

 Access to XMLHttpRequest at 'http://localhost:7003/rest/model/atg/userprofiling/ProfileActor/login' from origin 'http://localhost' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status

Java错误是

 ]] Root cause of ServletException.

对此的任何帮助将不胜感激。

Answer 1

RestPipelineServlet应该将请求传递给正确的RestProcessor。查看RestProcessor接口，似乎仅实现要使用的METHODS的子集（DOC）。因此，对于您的解决方案，您可能必须在ActorProcessor中实现doRESTOptions方法并从那里工作。

将其注入应用程序并不是一件容易的事。您还需要对RestPipelineServlet中实现的方法进行METHOD验证，您需要查看和覆盖/扩展。
