gRPC代理配置

[cyrnicolase]

我的核心配置如下：

cluster_conf.data

"rpc_cluster": {
              "BackendConf": {
                  "Protocol": "h2c",          // 指定代理到后端使用 h2c 协议
                  "TimeoutConnSrv": 2000,
                  "TimeoutResponseHeader": 50000,
                  "MaxIdleConnsPerHost": 0,
                  "RetryLevel": 0
              },
              "ClusterBasic": {
                  "TimeoutReadClient": 30000,
                  "TimeoutWriteClient": 60000,
                  "TimeoutReadClientAgain": 30000,
                  "ReqWriteBufferSize": 512,
                  "ReqFlushInterval": 0,
                  "ResFlushInterval": -1,
                  "CancelOnClientClose": false
              }
          }

                  "ClusterName": "rpc_cluster"
              },
              {

                  "h2;level=2"
              ]
          }
      }
  }

场景问题1：

在我使用 grpc 客户端发起请求的时候；BFE 这边出现报错:

{"schema":"REQUEST_LOG","time":"2023-11-24 11:29:46","clientip":"10.0.2.179","serverip":"10.0.2.160:80","host":"","product":"rpc_product","user_agent":"-","status": "415","error":"-"}
{"schema":"SESSION_LOG","time":"2023-11-24 11:29:46","clientip":"10.0.2.179:50253","start_time":"2023-11-24 11:29:46.346912835 +0800 CST m=+1525.693990310","end_time":"2023-11-24 11:29:46.348221523 +0800 CST m=+1525.695298998","overhead":"1.308688ms","read_total":"0", "write_total":"0","keepalive_num":"1","error":"CLIENT_BAD_REQUEST,malformed HTTP request "SM""}

在gRPC 客户端这边的报错是：

could not greet: rpc error: code = Unavailable desc = connection error: desc = "error reading server preface: http2: frame too large"

场景问题2：

在我的 host_rule.data 中，如果没有指定 DefaultProduct 为我的 gRPC 产品线，那么就会出现如下错误（找不到产品线）：

{"schema":"REQUEST_LOG","time":"2023-11-24 11:32:54","clientip":"10.0.2.179","serverip":"10.0.2.160:80","host":"","product":"-","user_agent":"-","status": "500","error":"BK_FIND_PRODUCT,no product found"}
{"schema":"SESSION_LOG","time":"2023-11-24 11:32:54","clientip":"10.0.2.179:50306","start_time":"2023-11-24 11:32:54.441249565 +0800 CST m=+6.249069142","end_time":"2023-11-24 11:32:54.441582607 +0800 CST m=+6.249402155","overhead":"333.013µs","read_total":"0", "write_total":"0","keepalive_num":"1","error":"-"}

辛苦帮忙看看是哪里还有哪里的配置我没有配置到？
