[英]Getting Expected top-level statement (e.g. "message") when trying to create 2D array in Protobuf
I am using trying to create a 2d array in.proto file like this:我正在尝试创建一个二维数组 in.proto 文件,如下所示:
message Foo {
repeated int32 items = 1;
}
repeated Foo items= 1;
but on generating the.pb.go file, getting the error for this line repeated Foo items= 1;
但是在生成 .pb.go 文件时,出现此行的错误
repeated Foo items= 1;
Getting Expected top-level statement (eg "message")
Has anyone ever came across this error?有没有人遇到过这个错误?
Please let me know how could we resolve this issue?请让我知道我们如何解决这个问题?
You cannot have a field at the top level, everything should be enclosed in a message or enum.顶层不能有字段,所有内容都应包含在消息或枚举中。 So in your case you should have something like:
所以在你的情况下你应该有这样的东西:
message Foo {
repeated int32 items = 1;
}
message Bar {
repeated Foo items = 1;
}
Then you will be able to set the items by doing the following:然后您将能够通过执行以下操作来设置项目:
&pb.Bar {
Items: []*pb.Foo {
{ Items: []int32{1, 2, 3, 4, 5, 6} },
{ Items: []int32{7, 8, 9, 10, 11, 12} },
},
}
where pb is the name for the import of the package you defined in your proto file.其中 pb 是您在 proto 文件中定义的 package 的导入名称。 Eg:
例如:
proto:原型:
option go_package = "example.com/m/proto";
go: go:
import pb "example.com/m/proto"
