Dapr 提供了帮助开发 PHP 应用的 SDK。你可以使用他们来创建 PHP 客户端、服务器和 virtual actors。

安装指南

前期准备

可选条件

Docker
xdebug – 用于调试

初始化项目

在您想要创建服务的目录中，运行 composer init 并回答问题。使用 composer require dapr/php-sdk 安装，并安装您可能希望使用的其他依赖项。

配置服务

创建一个 config.php ，复制下面的内容：

<?php
use Dapr\Actors\Generators\ProxyFactory;
use Dapr\Middleware\Defaults\{Response\ApplicationJson,Tracing};
use Psr\Log\LogLevel;
use function DI\{env,get};
return [
    // set the log level
    'dapr.log.level'               => LogLevel::WARNING,
    // Generate a new proxy on each request - recommended for development
    'dapr.actors.proxy.generation' => ProxyFactory::GENERATED,
    // put any subscriptions here
    'dapr.subscriptions'           => [],
    // if this service will be hosting any actors, add them here
    'dapr.actors'                  => [],
    // if this service will be hosting any actors, configure how long until dapr should consider an actor idle
    'dapr.actors.idle_timeout'     => null,
    // if this service will be hosting any actors, configure how often dapr will check for idle actors 
    'dapr.actors.scan_interval'    => null,
    // if this service will be hosting any actors, configure how long dapr will wait for an actor to finish during drains
    'dapr.actors.drain_timeout'    => null,
    // if this service will be hosting any actors, configure if dapr should wait for an actor to finish
    'dapr.actors.drain_enabled'    => null,
    // you shouldn't have to change this, but the setting is here if you need to
    'dapr.port'                    => env('DAPR_HTTP_PORT', '3500'),
    // add any custom serialization routines here
    'dapr.serializers.custom'      => [],
    // add any custom deserialization routines here
    'dapr.deserializers.custom'    => [],
    // the following has no effect, as it is the default middlewares and processed in order specified
    'dapr.http.middleware.request'  => [get(Tracing::class)],
    'dapr.http.middleware.response' => [get(ApplicationJson::class), get(Tracing::class)],
];

创建服务

创建index.php并放入以下内容：

<?php
require_once __DIR__.'/vendor/autoload.php';
use Dapr\App;
$app = App::create(configure: fn(\DI\ContainerBuilder $builder) => $builder->addDefinitions(__DIR__ . '/config.php'));
$app->get('/hello/{name}', function(string $name) {
    return ['hello' => $name];
});
$app->start();

试试吧

用 dapr init 初始化 Dapr，然后用 dapr run -a dev -p 3000 -- php -S 0.0.0.0:3000 启动项目。

现在，您可以打开网络浏览器访问http://localhost:3000/hello/world，用您的名字，宠物的名字或您想要的任何名称替换world。

恭喜，你已经建立了你的第一个 Dapr 服务！我很高兴看到您会怎么做！
