根因分析

protobuf消息在传输过程中被损坏，导致校验和验证失败。

English

The protobuf message was corrupted during transmission, causing a checksum validation failure.

解决方案

  1. 80% 成功率 Implement retry with a new context to avoid reusing corrupted data. 
    for i := 0; i < 3; i++ {
    ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
    resp, err := client.SomeRPC(ctx, req)
    cancel()
    if err == nil { return resp }
    if status.Code(err) != codes.DataLoss { return err }
    time.Sleep(100 * time.Millisecond)
}
  2. 95% 成功率 Use a reliable transport like TLS to reduce corruption. 
    conn, err := grpc.Dial("localhost:8080", grpc.WithTransportCredentials(creds))

无效尝试

常见但无效的做法:

  1. Ignore the checksum and resend the same message. 70% 失败

    The same corruption may occur again if the underlying network issue persists.

  2. Disable checksum validation on the server. 90% 失败

    This compromises data integrity and is not recommended.
