解决方案

  1. 95% 成功率 
    import "google.golang.org/protobuf/encoding/protojson"
opts := protojson.UnmarshalOptions{DiscardUnknown: true}
err := opts.Unmarshal(data, msg)
  2. 90% 成功率 
    // Add the field to your .proto file and regenerate.
// message YourMessage { string unknown_field = 1; }

无效尝试

常见但无效的做法:

  1. 60% 失败

    This is a temporary fix; the field may reappear or be required by other clients.

  2. 80% 失败

    encoding/json does not understand protobuf field names and will produce incorrect results.
