HTTP4组件忽略了我的协议，主机名和端口号

我正在尝试调用https服务。该网址是 https4：//httpbin.org/get？connectTimeout = 800
但它正在尝试连接 enter image description here 

        restConfiguration()
                .component("restlet").port(8080)
                .bindingMode(RestBindingMode.off)
                .apiContextPath("api-doc")
                .apiProperty("api.title", "Unified Item API")
                .apiProperty("api.version", "v1");

        rest().path("/api/v1/raw")
                .get().to("direct:agg");

        from("direct:agg")
                .validate(authorizationPredicate)
                .to("https4://httpbin.org/get?connectTimeout=800");

这是日志的相关部分：

事实证明，REST使用者将标头Exchange.HTTP_URI设置为其接收的URL。 HTTP4生产者使用此标头来覆盖给出的URL中的内容。解决方法是删除标题，如下所示：

           from("direct:agg")
                    .validate(authorizationPredicate)
                    .removeHeader("Exchange.HTTP_URI")
