Detailed introduction to inter-service communication RPC

This article brings you a detailed introduction to RPC communication between services. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Microservices are now prevalent, and there are probably two ways to communicate between services: Api and Rpc.

The following two examples will let you understand the difference between Api and Rpc.

Lie Zi 1 Addition, deletion, modification and review of articles.

Api implementation:

Router::get('/article/{id}','ArticleController@get');
Router::post('/article','ArticleController@create');
Router::put('/article/{id}','ArticleController@edit');
Router::delete('/article/{id}','ArticleController@delete');

Then call the model in the controller Article

return Article::find($id)->toArray();

Rpc implementation

RpcServer::add('Article');

Yes, just one line of code

Liezi 2 calculator

If there is a calculator on machine A Counter is provided to other machines in the form of Rpc.

Calculator Counter code

class Counter
{

    private $i = 0;

    public function __construct($i = 0)
    {
        $this->i = $i;
    }

    // 加法
    public function add($v)
    {
        $this->i += $v;
        return $this;
    }

    // 减法
    public function sub($v)
    {
        $this->i -= $v;
        return $this;
    }

    // 乘法
    public function mul($v)
    {
        $this->i *= $v;
        return $this;
    }

    // 除法
    public function p($v)
    {
        $this->i /= $v;
        return $this;
    }

    // 获取结果
    public function get()
    {
        return $this->i;
    }
}

Rpc implementation

RpcServer::add('Counter');

Rpc client call

$c = new ClientCounter(10);
echo $c->add(3)->mul(2)->sub(10)->p(5)->get();
