如何在Micronaut中获取完整的请求头列表

import io.micronaut.http.HttpRequest;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;

@Controller
public class MyController {

    @Get("/headers")
    public String getHeaders(HttpRequest<?> request) {
        // 获取请求头列表的代码将在这里
        return "Headers";
    }
}

import io.micronaut.http.HttpHeaders;

@Controller
public class MyController {

    @Get("/headers")
    public String getHeaders(HttpRequest<?> request) {
        HttpHeaders headers = request.getHeaders();
        // 获取请求头列表
        return headers.toString();
    }
}
