golang客户端与rust服务端通信

golang-rust-grpc

一、golang_client

1、环境设置

export GOPROXY=https://goproxy.io
go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
将protoc-gen-go加入环境变量：
echo export PATH="$PATH:/Users/lr/go/bin" >> ~/.bash_profile
source ~/.bash_profile

2、编译proto文件

cd ./proto
protoc -I . --go_out=plugins=grpc:. ./mygrpc.proto

3、编写golang_client实现代码

4、go mod设置

go mod init golang_client

go mod tidy

5、把proto目录移动到vendor下

lrdeMacBook-Pro:golang_client lr$ ll vendor
total 8
drwxr-xr-x  3 lr  staff    96 Feb 22 10:10 github.com
drwxr-xr-x  3 lr  staff    96 Feb 22 10:10 golang.org
drwxr-xr-x  5 lr  staff   160 Feb 22 10:10 google.golang.org
-rw-r--r--  1 lr  staff  3888 Feb 22 10:10 modules.txt
drwxr-xr-x  4 lr  staff   128 Feb 22 10:11 proto

6、重启编译器

7、编译

CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build -o ./bin/golang-client .

二、rust_server

1、编译proto文件

创建build.rs:

extern crate tonic_build;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    tonic_build::compile_protos("proto/mygrpc.proto")?;
    Ok(())
}

2、编译

cargo build --bin rust-server

三、运行

1、先运行rust-server

./target/debug/rust-server

获取到请求：Request { metadata: MetadataMap { headers: {"content-type": "application/grpc", "user-agent": "grpc-go/1.35.0", "te": "trailers"} }, message: HelloRequest { request: "Sir,I am grpc client!" ensions: Extensions }

2、接着运行golang-client

./bin/golang-client

grpc服务端回应 收到请求:Sir,I am grpc client! 回复:Successful! This is grpc server!
