希望能对sofarpc中 rest协议，直接通过httpClient调用能支持

通过新增过滤器实现

The issue proposes adding a filter so SOFARPC REST calls can be made directly through an HTTP client, with an attached diagram as the only implementation detail. Start by locating the REST protocol and HTTP client entry points, then clarify the filter behavior and expected request flow before defining what successful direct calls should support.
