微服务 A 调用另一个微服务 B 时，微服务 A 如何获取 B 的版本号？
尝试调用 Invocation 的 getMicroserviceVersionRule() 方法 , 结果是 `0.0.0.0+`
使用场景如下：
```java
@Subscribe
public void consume(InvocationFinishEvent event) {
if (event == null) {
log.error("event is null");
return;
}
Invocation invocation = event.getInvocation();
Response response = event.getResponse();
if (invocation == null || response == null) {
log.error("invocation or response is null");
return;
}
if (InvocationType.CONSUMER.equals(invocation.getInvocationType())) {
// How to get provider service version?
}
}
```
