我在localhost中使用webclient时遇到了这个错误,你们能帮我吗??

连接被拒绝意味着没有服务器在侦听address:port. 你可以和我核对一下 netstat -tulpen 哪些端口在哪个地址开放。

不,我们不能通过localhost直接调用,这里的术语是“container call container”,所以,我们应该通过container name一起调用。
更改docker组合如下:

order-service:
  build: docker/order-service
  container_name: order-service
  ports:
    - 8082:8080

然后,在客户机服务中,我们只定义如下主机:
专用字符串主机名=“http://order-service:8080/订单服务/欢迎”;
您可以看到,当我们通过浏览器(real client)调用订单服务时,我们通过扩展端口(8082)调用,但如果容器调用容器,我们应该通过它调用 s container 的名称和端口(8080)。
