从golang的fixed64 protobuf字段读取int64

Question

I have a field that is of type fixed64 in a .proto file.

I want to read it as an int64 field:

score := int64(pb_obj.Score)

When I try to compile the line agove I get the error message cannot convert pb_obj.Score (type *uint64) to type int64. I tried converting the a uint64 as well, and got an almost identical message.

Answer 1

pb_obj.Score's type seems to be *uint64 (pointer to uint64), not uint64. You just need to access to the value the pointer is referencing:

score := int64(*pb_obj.Score)

(See the * prefix as the difference)
