根因分析
protobuf 消息字段类型不匹配;例如,在期望字符串的地方发送了整数。
English
The protobuf message field type mismatch; e.g., sending an integer where a string is expected.
解决方案
-
95% 成功率
string age = 1; protoc --go_out=. *.proto
-
90% 成功率
req := &pb.Person{Age: strconv.Itoa(30)} -
85% 成功率
if _, ok := req.Age.(string); !ok { return status.Error(codes.InvalidArgument, "age must be string") }
无效尝试
常见但无效的做法:
-
Continuing to send incorrect type.
100% 失败
Same error persists.
-
Using type assertion without changing proto.
80% 失败
Proto definition determines wire format.
-
Blaming server for type checking.
50% 失败
Client must follow proto definition.
