解决方案

  1. 95% 成功率 
    msg := &pb.YourMessage{
    Id: proto.String("some-id"),
    // set other required fields
}
data, err := proto.Marshal(msg)
if err != nil { log.Fatal(err) }
  2. 90% 成功率 
    if err := proto.CheckInitialized(msg); err != nil {
    log.Fatalf("message not initialized: %v", err)
}
data, err := proto.Marshal(msg)

无效尝试

常见但无效的做法:

  1. 70% 失败

    Changing the proto definition may break compatibility with other services and requires regeneration.

  2. 60% 失败

    Migrating to proto3 is a significant change and may not be feasible for existing systems.
