grpc 使用压缩器 compressor wsarecv: An existing connection was forcibly closed by the remote host.

 wsarecv: An existing connection was forcibly closed by the remote host.

 

优化方案：

1）客户端连接复用

2）压缩传输数据

 

rpc error: code = Unimplemented desc = grpc: Decompressor is not installed for grpc-encoding "gzip"
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x28 pc=0x9c0a1a]

 抓包分析，压缩前后数据字节数对比

 

 

// NewGRPCServer new a gRPC server.
func NewGRPCServer() *grpc.Server {
   var opts = []grpc.ServerOption{}
   /*
      rpc error: code = Unimplemented desc = grpc: Decompressor is not installed for grpc-encoding "gzip"
      panic: runtime error: invalid memory address or nil pointer dereference
      [signal 0xc0000005 code=0x0 addr=0x28 pc=0x9c0a1a]
   */
   //grpc.UseCompressor(gzip.Name)

   //encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))
   srv := grpc.NewServer(opts...)
   pb.RegisterReportCenterServer(srv, &server{})
   return srv
}

 

func NewClient() (c pb.ReportCenterClient, conn *grpc.ClientConn) {
   bytes := 1024 * 1024 * 4 * 4
   cp := grpc.ConnectParams{}
   cp.MinConnectTimeout = 16 * time.Second
   co := []grpc.CallOption{grpc.UseCompressor(gzip.Name)}
   opts := []grpc.DialOption{
      grpc.WithInsecure(),
      grpc.WithBlock(),
      grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(bytes)),
      grpc.WithConnectParams(cp),
      grpc.WithDefaultCallOptions(co...),
   }
   //encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))

   conn, err := grpc.Dial("120.24.184.164:12345", opts...)
   if err != nil {
      fmt.Println("err-NewClient", err)
      //log.SugarLogger.Errorf("grpc", err)
      return
   }
   return pb.NewReportCenterClient(conn), conn
}

encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))
1）
Svr
encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))
Cli
encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))
当发送的字节数多时，少时可以正常收发
rpc error: code = Unavailable desc = error reading from server: read tcp 10.128.1.192:49347->10.4.84.14:12345: wsarecv: An existing connection was forcibly closed by the remote host.

修改Cli，添加CallOption即可
co := []grpc.CallOption{grpc.UseCompressor(gzip.Name)}
opts := []grpc.DialOption{
grpc.WithInsecure(),
grpc.WithBlock(),
grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(bytes)),
grpc.WithConnectParams(cp),
grpc.WithDefaultCallOptions(co...),
}
之后修改Svr
encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))
或
grpc.UseCompressor(gzip.Name)
均可
2）
Cli
encoding.RegisterCompressor(encoding.GetCompressor(gzip.Name))
Svr
grpc.UseCompressor(gzip.Name)
也报错

3）Cli

//co := []grpc.CallOption{grpc.UseCompressor(gzip.Name)}
opts := []grpc.DialOption{
   grpc.WithInsecure(),
   grpc.WithBlock(),
   grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(bytes)),
   grpc.WithConnectParams(cp),
   //grpc.WithDefaultCallOptions(co...),
}
grpc.UseCompressor(gzip.Name)

这样写，也报错
