轻松拦截器

Question

I wonder if it is as hard as I currently try to achieve it. I use Some Interceptor for security in my RESTEasy application. The interceptor implements javax.ws.rs.container.ContainerRequestFilter .

I use such a code to access request data:

if (((PostMatchContainerRequestContext) requestContext).getHttpRequest().getHttpMethod().equals("GET")) {
   requestedId = Long.parseLong(requestContext.getUriInfo().getQueryParameters().get("id").get(0));
} else {
   postDataMap = getPostData(requestContext);
}

and

private LinkedHashMap getPostData(ContainerRequestContext requestContext) {
   Object obj = null;

    try {
       String result = IOUtils.toString(requestContext.getEntityStream());
       ObjectMapper mapper = new ObjectMapper();
       obj = mapper.readValue(result, Object.class);
       System.out.println(obj);
     } catch (IOException e) {
        e.printStackTrace();
     }
   return (LinkedHashMap) obj;
}

But it seams ridiculous to access request data in such a way. Now I wanted to access DELETE-Request data but couldn't find any solution. Is there a much proper way to achieve what I am currently doing?

By intercepting you mean to check data before it goes to the rest layer? I have achieved this with implementing Filter interface ( https://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/Filter.html ).

您可以在标头中设置安全信息，获取如下值：

String logintoken = crc.getHeaderString("token");
