我正在使用Camel serviceCall来拨打我的eureka VIP。主机和端口按预期解析。但响应是400并且抛出错误。我的serviceCall看起来如下：
from("direct:servicecall")
.setBody().constant(null)
.setHeader(Exchange.HTTP_METHOD, constant(HttpMethods.GET))
.serviceCall().name("eureka_vip_name")
.expression()
.simple("http4:${header.CamelServiceCallServiceHost}:${header.CamelServiceCallServicePort}"
+ "service call path and parameters")
.end()
添加错误日志：

我尝试使用postMan（chrome扩展名）使用相同的url：当从postMan命中时，我使用ec2实例DNS名称作为主机，它给了我预期的响应，即200 OK，预期的身体作为结果。< / p>
