假客户机：如何记录请求发送到的服务器名称？

Question

我正在使用一个假客户机成功地调用一个RESTendpoint，并将日志记录打开到FULL。这有助于向我显示发送的请求和收到的响应。但是，我看不到请求被发送到哪个服务器。它只告诉我它被发布到http://foo-service，这是服务的名称，而不是服务器的名称。

如何记录此请求发送到的服务器名称？

c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] ---> POST http://foo-service/some-endoint HTTP/1.1
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] Accept: application/json
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] Content-Type: application/json
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] Content-Length: 15
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] 
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] {"name":"John"}
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] ---> END HTTP (15-byte body)
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] <--- HTTP/1.1 200 (8ms)
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] Transfer-Encoding: chunked
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] X-Application-Context: fooService:9006
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] Date: Tue, 10 Oct 2017 09:25:36 GMT
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] Content-Type: application/json;charset=UTF-8
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] 
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] {"result":"Hello John"}
c.l.l.r.service.FooFeignClient : [FooFeignClient#bar] <--- END HTTP (23-byte body)

@Bean
public feign.Logger.Level feignLoggerLevel() {
    return Logger.Level.FULL;
}

您需要提供自己的记录器来实现这一点。默认的记录器非常简单，在发送请求之前记录主机。当使用功能区时，响应将提供这些信息。如果重写LogAndreBufferResponse方法，则Response.url属性将是提交的整个url，包括主机名。

protected Response logAndRebufferResponse(
    String configKey, 
    Level logLevel, 
    Response response,
    long elapsedTime) throws IOException {

    /* ask the response for the request and log the uri */
    log(response.request.url());
}
