最近想试一下kitex，但是官方文档里例子都是thrift的，没有protobuf的，因此记录一下配置踩坑的过程。
1. 安装protoc
从官方Github下载安装最新的protoc

# 我这里是linux amd64版本
mkdir protobuf && cd protobuf
wget https://github.com/protocolbuffers/protobuf/releases/download/v3.19.4/protoc-3.19.4-linux-x86_64.zip
unzip ./protoc-3.19.4-linux-x86_64.zip
sudo cp ./bin/protoc /usr/local/bin
protoc --version

2. 安装golang插件
参见：谷歌官方文档

|
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
|
3. 安装kitex

|
go install github.com/cloudwego/kitex/tool/cmd/kitex@latest
go install github.com/cloudwego/thriftgo@latest # optional

4. kitex we go!
编写一个proto文件

syntax = "proto3";
package tutorial;
import "google/protobuf/timestamp.proto";
option go_package = "github.com/protocolbuffers/protobuf/examples/go/tutorialpb";
message Person {
string name = 1;
int32 id = 2; // Unique ID number for this person.
string email = 3;
enum PhoneType {
MOBILE = 0;
HOME = 1;
WORK = 2;
}
message PhoneNumber {
string number = 1;
PhoneType type = 2;
}
repeated PhoneNumber phones = 4;
int32 last_updated = 5;
}
// Our address book file is just one of these.
message AddressBook {
repeated Person people = 1;
}

然后编译它

kitex -module example -type protobuf ./test.proto

编译好的go在kitex_gen文件夹下
问题小计
- 编译protobuf出现报错：kitex_opt unknown flag
这个问题是没有安装protobuf的golang插件，安装一下就好了，同时注意protoc要是最新版本的
