Docker php curl 连接被拒绝

Question

[下面的演示]

问候开发人员，最近我正在尝试对 php 网站进行 docker 化。 但是当我尝试从一个到另一个 curl 时连接被拒绝。

基本上我有三个站点：

• api
• 第一站
• 第二站点

问题是connection is refused when I try to call api from first-site.

./docker-compose.yml

version: "3.1"
services:
  www:
    build: ./www/.
    ports:
      - "0.0.0.0:8080:80"
      - "0.0.0.0:443:443"
    volumes:
      - ./htdocs:/var/www
      - ./www/conf:/etc/httpd/conf
    networks:
      - local

  php:
    build: ./php/.
    ports:
      - '9000'
    volumes:
      - ./htdocs:/var/www
    networks:
      - local

networks:
  local:
    driver: bridge

    $ch = curl_init();

    // Check if initialization had gone wrong*
    if ($ch === false) {
        throw new Exception('failed to initialize');
    }
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_VERBOSE, true);
    $response = curl_exec($ch);
    // Check the return value of curl_exec(), too
    if ($response === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }
    curl_close($ch);

    $json = json_decode($response,true);

    if ($json==null) {

        exit;

} catch (Exception $e) {

        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);
}
?>

当我执行这段代码时，我得到了

致命错误：Curl 失败，错误 #56：代理 CONNECT 在第 xx 行的 /var/www/api/xxxxxxp 中中止

我自己的假设是，我在 docker-compose.yml 中拥有的php和www容器没有连接或链接在同一个网络上，但直到现在我才弄清楚解决方案。 请帮忙！！！！ 我很感激<3

您的服务名称是可联网的。 例如，我可以将mariadb放在我的数据库连接中，而不是localhost或 ip。 在下面的示例中， awesome.scot是我的 Apache 服务器，您会注意到另一个名为app的应用程序，它实际上只是挂载文件，因此可以为每个 web 站点添加服务，如果您引用服务名称：通话将毫无问题地完成:-)

这是我的 LAMP sdtack 的 Docker 组合文件。 如果您想尝试它或从中窃取信息，您可以在这里找到它https://github.com/delboy1978uk/lamp ，它还带有 mailhog、自签名 ssl、xdebug 等。
