Question

使用请求方法POST进行API调用时出现问题。预检OPTIONS方法失败。我在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);
  }
}

浏览器错误为

 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.
javax.servlet.ServletException: The request method type is not supported: OPTIONS
        at atg.rest.servlet.RestPipelineServlet.serviceRESTRequest(RestPipelineServlet.java:493)
        at atg.rest.servlet.RestPipelineServlet.service(RestPipelineServlet.java:274)
        at atg.servlet.pipeline.PipelineableServletImpl.passRequest(PipelineableServletImpl.java:157)

        at atg.rest.servlet.RestPipelineServlet.service(RestPipelineServlet.java:278)
        Truncated. see log file for complete stacktrace

对此将提供任何帮助。

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

将其注入到应用程序中并非易事。在METHOD中已实现的方法上也可能有RestPipelineServlet可用的验证，您需要研究它们并进行覆盖/扩展。

不支持请求方法类型：ATG中的OPTIONS
