Use protobuf in go

Compile

The steps to refer to [1] [2] are as follows:

• 1. Install the compiler.
  It is easy to miss here. At the beginning, because there was no such step, it was impossible to find protoc to
  download the corresponding system compression package. After decompression, put protoc.exe in gopath / bin, which is under the Go installation path. In the bin
• 2. Install protobuf-go

go install google.golang.org/protobuf/cmd/protoc-gen-go

Encountered the following error

can't load package: package google.golang.org/protobuf/cmd/protoc-gen-go: cannot find package "google.golang.org/protobuf/cmd/protoc-gen-go" in any of:
        C:\Go\src\google.golang.org\protobuf\cmd\protoc-gen-go (from $GOROOT)
        C:\Users\peikai\go\src\google.golang.org\protobuf\cmd\protoc-gen-go (from $GOPATH)

If you get the same error, get it first

go get google.golang.org/protobuf/cmd/protoc-gen-go

• Compile

protoc -I=$SRC_DIR --go_out=$DST_DIR $SRC_DIR/addressbook.proto

When developing by yourself, directly cd to the * .proto directory and execute the following simple command:

protoc --go_out=. *.proto
