如何在 Docker 容器中测试 PHP API

Question

我在 Docker 容器中使用 PHP/Symfony 构建了一个 api。我想测试一下。

要做到这一点：

• 首先：我进入我的容器：docker-compose exec da-invoicing-php sh

• 第二个：我运行测试：vendor/bin/simple-phpunit

在我的测试中我有这个要求：

$result = $this->client->request(
        'POST',
        '10.110.167.124:8080/api/v1/course_invoices',
        [
            RequestOptions::HEADERS => [
                'Accept' => 'application/ld+json',
                'Content-Type' => 'application/json',
                'Authorization' => "Bearer {$this->token}",
            ],
            RequestOptions::BODY => json_encode([
                'courseInstanceId' => self::COURSE_INSTANCE,
            ]),
        ]
    );

如您所见，我向端点“'10.110.167.124:8080/api/v1.....”请求。它有效，但我知道我不能这样继续下去。

我尝试使用“localhost”、“localhost:8080”、“http://localhost”等...但没有成功。我总是有这个错误：

GuzzleHttp\Exception\ConnectException：cURL 错误 7：无法连接到 localhost 端口 8080：连接被拒绝（请参阅https://curl.haxx.se/libcurl/c/libcurl-errors.html）

那么如何在容器内进行这个测试呢？

你不能在你的 PHP 容器中直接使用 localhost 它不提供 HTTP，它是 php-fpm。

你必须调用nginx容器da-invoicing-api

$result = $this->client->request(
    'POST',
    'da-invoicing-api/api/v1/course_invoices',
    [
        RequestOptions::HEADERS => [
            'Accept' => 'application/ld+json',
            'Content-Type' => 'application/json',
            'Authorization' => "Bearer {$this->token}",
        ],
        RequestOptions::BODY => json_encode([
            'courseInstanceId' => self::COURSE_INSTANCE,
        ]),
    ]
);

Docker-compose create host alias 为您的 compose 文件中的每个容器（同一网络上的其他容器可以使用该服务名称）。
