Java @使用curl-b测试时，HeaderParam（“Cookie”）返回null；cookie:value"；

我有功能

@POST
@Consumes({ ExampleMediaTypes.PLAINTEXT_0_1_0, MediaType.TEXT_PLAIN, ExampleMediaTypes.SIMPLE_PROTOBUF_0_1_0, ExampleMediaTypes.SIMPLE_JSON_0_1_0, ExampleMediaTypes.STRUCTURED_JSON_0_1_0 })
@Produces({ PredictionMediaTypes.PLAINTEXT_0_1_0 })
@Path("/main")
public ChunkedOutput<String> doPredict(ExamplesIterable examplesIterable,@HeaderParam("User-Agent") String userAgent, @HeaderParam("Cookie") String cookies) throws IOException {
    System.out.println("hello");
    System.out.println(cookies);
    System.out.println(userAgent);
    return new RequestHandler(executorService, exampleProcessorFactory).handleRequest(examplesIterable);
}

我明白了：

hello
null
curl/7.35.0

有什么问题吗？这是错误的卷曲请求还是注释错误

hello
null
curl/7.35.0
