如何在Docker容器中测试PHP

Question

我在一个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:我进入了我的容器: docker-compose exec da-invoicing php sh
• 第二:我运行测试:供应商/bin/简单-phpunit。

在我的测试中，我有一个请求：

$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，我请求端点“10.110.167.124:8080/api/v1.”，但我知道不能继续这样做。

我试过用'localhost'，'localhost:8080'，'http://localhost'，等等.但没有成功。我总是有这样的错误：

GuzzleHttp\Exception\ConnectException: cURL错误7:连接到本地主机端口8080失败:连接被拒绝(参见https://curl.haxx.se/libcurl/c/libcurl-errors.html)

那么如何在容器内进行这个测试呢？

您不能在PHP容器中直接使用本地主机--它不提供HTTP，它是php。

您必须调用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-为撰写文件中的每个容器编写创建主机别名 (同一网络上的其他容器可以使用服务名称)。
