PHP RPC框架 hprose 上手玩玩

RPC是啥？ 远程过程调用， 简单来说就是 另一种api调用的形式， 不过是在tcp层次的。
例子：
php 7.2.9
composer 1.8.5
composer.json

{
    "name": "hprose/examples",
    "description": "examples of hprose",
    "authors": [
        {   
            "name": "frans",
            "email": "dafa1680@gmail.com"
        }   
    ],  
    "require": {
        "php": ">=7.0",
        "hprose/hprose": "^2.0"
    }   
}

server.php

<?php
require './vendor/autoload.php';

function hello($name)
{
    return "Hello " . $name . PHP_EOL;
}

use Hprose\Socket\Server;
$server = new Server("tcp://0.0.0.0:1314");
$server->setErrorTypes(E_ALL);
$server->setDebugEnabled();
$server->addFunction('hello');
$server->start();

client.php

<?php
require_once "./vendor/autoload.php";

use \Hprose\Future;
use \Hprose\Socket\Client;

$test = new Client("tcp://127.0.0.1:1314");
$test->fullDuplex = true;

Future\co(function () use ($test) {
    try {
        var_dump((yield $test->hello("yield world1")));
        var_dump((yield $test->hello("yield world2")));
        var_dump((yield $test->hello("yield world3")));
        var_dump((yield $test->hello("yield world4")));
        var_dump((yield $test->hello("yield world5")));
        var_dump((yield $test->hello("yield world6")));
    } catch (\Exception $e) {
        echo $e->getMessage() . PHP_EOL;

        echo $e->getTraceAsString();
    }
});

最后跑起来：
php server.php // 没有输出，会常驻进程， 如果有输出那就是报错啦。

php client.php // 输出：

E:\rpc\hprose-php>php client.php
E:\rpc\hprose-php\client.php:12:
string(20) "Hello yield world1
"
E:\rpc\hprose-php\client.php:13:
string(20) "Hello yield world2
"
E:\rpc\hprose-php\client.php:14:
string(20) "Hello yield world3
"
E:\rpc\hprose-php\client.php:15:
string(20) "Hello yield world4
"
E:\rpc\hprose-php\client.php:16:
string(20) "Hello yield world5
"
E:\rpc\hprose-php\client.php:17:
string(20) "Hello yield world6
"

完毕！
