windows php(laravel) grpc client 实战步骤

1.项目根目录composer.json文件"require": 节点添加下面这2个

"grpc/grpc": "~1.30.0",
"google/protobuf": "~v3.12.2"

然后执行更新命令composer update

2.下载grpc+protobuf的windows版本，因为官网上面的教程都是针对的linux系统做的指引。windows的话需要自己编译，还好github上面已经有大佬编译好了，

https://github.com/lifenglsf/grpc_for_windows，

上面这个地址下载下，比如保存到e:\grpc_for_windows-master

3.建立proto文件，例如:GrpcService.proto

syntax = "proto3";
package WxGrpc;

service GrpcService{
rpc Chat(ChatRequest) returns(ChatResponse);
}

message ChatRequest{
string Receiver = 1;
string Content = 2;
}

message ChatResponse{
int32 Status = 1;
string Msg = 2;
}

4.命令行下切到php项目根目录，然后执行下面命令

"E:\grpc_for_windows-master\x64\protoc.exe" --proto_path="protos文件目录" --php_out=生成的php文件要存放的目录 --grpc_out=生成的php文件要存放的目录 --plugin=protoc-gen-grpc=E:\grpc_for_windows-master\x64\grpc_php_plugin.exe GrpcService.proto

5.完成后就可以写GrpcClient代码了

<?
namespace App\Extend;

class QsGrpcClient{
    private $client;
    private $response=["code"=>-1,"msg"=>""];
    public function __construct(){
        $this->client = new \WxGrpc\GrpcServiceClient("127.0.0.1:12828",[
            'credentials' => \Grpc\ChannelCredentials::createInsecure(),
        ]);
    }

    public function chat($receive,$content){
        $chatRequest=new \WxGrpc\ChatRequest();
        $chatRequest->setReceiver("Qs");
        $chatRequest->setContent("Haha");

        $resp = $this->client->Chat($chatRequest)->wait();
        return $this->handle($resp);
    }

    private function handle($resp){
        list($result, $status) = $resp;
        if($status->code){
            $this->response["code"]=$status->code;
            $this->response["msg"]=$status->details;
            return false;
        }
        return $result;
    }

    public function getResponse(){
        return $this->response;
    }
}
?>
