Jersey:将值从ContainerRequestFilter传递到端点

Question

我使用的是Jersey 2.9,我创建了一个过滤器,它将获取一个加密的标头值,并对其进行解密,然后将其传递给被调用的端点.我不知道如何做到这一点,我一直在互联网上搜索,但没有真正找到我想做的具体例子.调用过滤器,我只是将值从它传递到端点时出现问题.

你们能帮帮我吧!

以下是一些示例代码:

public class MyFilter implements ContainerRequestFilter
{

    @Override
    public void filter(ContainerRequestContext requestContext) throws WebApplicationException {

        String EncryptedString = requestContext.getHeaderString("Authentication");

        /* Doing some methods to remove encryption */

        /* Get a string which I want to pass to the endpoint which was called on, in this example: localhost:4883/rest/test */
    }
}

@Path("rest")
public class restTest
{

    @Path("test")
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String Testing(){

        /* Process the value from the MyFilter */
    }
}

Answer 1

您可以轻松修改标题或添加另一个标题:

@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
    requestContext.getHeaders().add("X-Authentication-decrypted", decryptedValue);
}

可以在资源方法中注入此值:

@GET
@Produces(MediaType.APPLICATION_JSON)
public String Testing(@HeaderParam("X-Authentication-decrypted") String auth) {

}
