习惯了使用TP框架调用swoft的RPC微服务，使用hyperf框架时，在其文档和百度都没有找到其他框架调用RPC的数据结构，故只能在hyperf的RPC服务端的请求链路进行日志输入和搭建hyperf的PRC客户端进行数据请求。
主要内容参考hyperf官方文档
1，搭建hyperf的RPC服务端(192.168.1.212)
在app目录下新建Rpc文件夹，先新建一个CalculatorServiceInterface接口文件，文件名CalculatorServiceInterface.php
<?php
namespace App\Rpc;
interface CalculatorServiceInterface
{
public function add(int $a, int $b): int;
}基于这个Interface，在该目录下添加一个实现方式的CalculatorService，文件名:CalculatorService.php
<?php
namespace App\Rpc;
use Hyperf\RpcServer\Annotation\RpcService;
/**
* 注意，如希望通过服务中心来管理服务，需在注解内增加 publishTo 属性
* @RpcService(name="CalculatorService", protocol="jsonrpc", server="jsonrpc")
*/
class CalculatorService implements CalculatorServiceInterface
{
public function add(int $a, int $b) : int
{
return $a +$b;
}
}
在这里使用了注解方式提供服务，name是服务名称，protocol指定使用了jsonrpc-http协议
打开config/autoload/server.php，在servers数组下，增加配置
'servers' => [
[
'name' => 'http',
'type' => Server::SERVER_HTTP,
'host' => '0.0.0.0',
'port' => 9701,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
SwooleEvent::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
],
],
[
'name' => 'jsonrpc-http',
'type' => Server::SERVER_HTTP,
'host' => '0.0.0.0',
'port' => 9704,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
SwooleEvent::ON_REQUEST => [Hyperf\JsonRpc\HttpServer::class, 'onRequest'],
],
],
// 这里主要用的是这个
[
'name' => 'jsonrpc',
'type' => Server::SERVER_BASE,
'host' => '0.0.0.0',
'port' => 9705,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
SwooleEvent::ON_RECEIVE => [\Hyperf\JsonRpc\TcpServer::class, 'onReceive'],
],
'settings' => [
'open_eof_split' => true,
'package_eof' => "\r\n",
'package_max_length' => 1024 * 1024 * 2,
],
],
],2.搭建hyperf的RPC客户端(192.168.1.45)
同样在app目录下新建Rpc文件夹，先新建一个CalculatorServiceInterface接口文件，文件名CalculatorServiceInterface.php
<?php
namespace App\Rpc;
interface CalculatorServiceInterface
{
public function add(int $a, int $b): int;
}修改app/Controllers/IndexController.php
<?php
declare(strict_types=1);
/**
* This file is part of Hyperf.
*
* @link https://www.hyperf.io
* @document https://hyperf.wiki
* @contact [email protected]
* @license https://github.com/hyperf/hyperf/blob/master/LICENSE
*/
namespace App\Controller;
use App\Rpc\CalculatorServiceInterface;
use Hyperf\Utils\Context;
use Hyperf\Utils\Coroutine;
use Hyperf\Utils\Parallel;
use Hyperf\Utils\ApplicationContext;
use Hyperf\Di\Annotation\Inject;
use Hyperf\HttpServer\Annotation\AutoController;
class IndexController extends AbstractController
{
public function index()
{
$user = $this->request->input('user', 'Hyperf');
$method = $this->request->getMethod();
return [
'method' => $method,
'message' => "Hello22 {$user}.",
];
}
public function add()
{
$client = ApplicationContext::getContainer()->get(CalculatorServiceInterface::class);
$value = $client->add(10, 20);
return $value;
}
}
新增客户端路由，修改config\routes.php，增加/add请求链接
<?php
declare(strict_types=1);
/**
* This file is part of Hyperf.
*
* @link https://www.hyperf.io
* @document https://hyperf.wiki
* @contact [email protected]
* @license https://github.com/hyperf/hyperf/blob/master/LICENSE
*/
use Hyperf\HttpServer\Router\Router;
Router::addRoute(['GET', 'POST', 'HEAD'], '/', 'App\Controller\IndexController@index');
Router::addRoute(['GET', 'POST', 'HEAD'],'/add', 'App\Controller\IndexController@add');
Router::get('/favicon.ico', function () {
return '';
});
创建客户端请求服务端的配置文件：config\autoload\services.php
<?php
declare(strict_types=1);
/**
* This file is part of Hyperf.
*
* @link https://www.hyperf.io
* @document https://hyperf.wiki
* @contact [email protected]
* @license https://github.com/hyperf/hyperf/blob/master/LICENSE
*/
return [
'consumers' => [
[
// The service name, this name should as same as with the name of service provider.
'name' => 'CalculatorService',
// The service registry, if `nodes` is missing below, then you should provide this configs.
// 服务接口名，可选，默认值等于 name 配置的值，如果 name 直接定义为接口类则可忽略此行配置，如 name 为字符串则需要配置 service 对应到接口类
'service' => \App\Rpc\CalculatorServiceInterface::class,
// 服务提供者的服务协议，可选，默认值为 jsonrpc-http
'protocol' => 'jsonrpc',
// 负载均衡算法，可选，默认值为 random
'load_balancer' => 'random',
// 对应容器对象 ID，可选，默认值等于 service 配置的值，用来定义依赖注入的 key
'id' => \App\Rpc\CalculatorServiceInterface::class,
// If `registry` is missing, then you should provide the nodes configs.
'nodes' => [
// Provide the host and port of the service provider.
['host' => '192.168.1.212', 'port' => 9705]
],
// 配置项，会影响到 Packer 和 Transporter
'options' => [
'connect_timeout' => 5.0,
'recv_timeout' => 5.0,
'settings' => [
// 根据协议不同，区分配置
'open_eof_split' => true,
'package_eof' => "\r\n",
// 'open_length_check' => true,
// 'package_length_type' => 'N',
// 'package_length_offset' => 0,
// 'package_body_offset' => 4,
],
// 当使用 JsonRpcPoolTransporter 时会用到以下配置
'pool' => [
'min_connections' => 1,
'max_connections' => 32,
'connect_timeout' => 10.0,
'wait_timeout' => 3.0,
'heartbeat' => -1,
'max_idle_time' => 60.0,
],
]
],
],
];3.启动服务端和客户端
热更新启动
php bin/hyperf.php server:watch
4.请求服务端地址
能输出结构表示没有问题，如果没能正确输出的话，仔细检查配置是否有错误（IP、端口、协议、类名等）
5.对服务端的RPC解析输出打印
vendor\hyperf\json-rpc\src\TcpServer.php
经测试RPC数据对接的方法是buildJsonRpcRequest方法，打印一下数据
得到数据为：
{"jsonrpc":"2.0","method":"\/calculator\/add","params":[10,20],"id":"62b6e12b05614","context":[]}
6.TP框架接入hyperf的PRC接口
$host = 'tcp://192.168.1.212:9705/';
$fp = stream_socket_client($host, $errno, $errstr);
if (!$fp) {
log_write("stream_socket_client fail errno={$errno} errstr={$errstr}", 'RPC');
throw new Exception("stream_socket_client fail errno={$errno} errstr={$errstr}");
}
// hyperf
// {"jsonrpc":"2.0","method":"\/calculator\/add","params":[10,20],"id":"62b6e12b05614","context":[]}
$req = [
"jsonrpc" => '2.0',
"method" => '/calculator/add',
'params' => [10,20],
'id' => '',
'context' => $ext,
];
$data = json_encode($req) . RPC_EOL;
fwrite($fp, $data);
$result = '';
while (!feof($fp)) {
$tmp = stream_socket_recvfrom($fp, 1024);
if ($pos = strpos($tmp, RPC_EOL)) {
$result .= substr($tmp, 0, $pos);
break;
} else {
$result .= $tmp;
}
}
fclose($fp);
dump($result);RPC服务端成功返回数据
至此，TP框架接入hyperf-PRC-Json就算是完成了，剩下的就是进一步优化请求方式美化代码，代码下载：
