我搜索了又搜索，并阅读了 http://docs.guzzlephp.org/en/stable/request-options.html 上的文档并在 https://curl.haxx.se/libcurl/c/libcurl-errors.html 处确认错误对于我的一生，我无法弄清楚发生了什么。我的/etc/hosts 文件中有 app-one 和 app-two 的 URL，我知道它们是正确的，因为我可以在浏览器中访问它们，也可以通过终端使用 cURL 访问它们。

我的设置:

Docker 容器配置为:

App 1 = php-fpm - responding app
App 2 = php-fpm - requesting app, using Guzzle 6.3.2

这就是我目前实现客户端的方式(包括我在尝试补救时添加的一些代码):

<?php
namespace Controllers\Api;

use \GuzzleHttp\Client;
// use \GuzzleHttp\Psr7\Uri;

define('URL', 'https://app-one.local/api/');

class Dashboard extends ApiController 
{
    private $http;

    public function __construct($container)
    {
        // We're using guzzle for our requests to help keep opportunity
        // for cURL errors to a minimum
        $this->http = new Client([
            'base_uri'          => URL,
            'timeout'           => 30.0,
            'allow_redirects'   => true,
            'verify'            => false,
            'curl'              => [
                 CURLOPT_VERIFYPEER => false
            ],
            'headers'           => [
                'User-Agent'        => 'curl/7.38.0',
            ],
        ]);

        $response = $this->http->get('member/sales/hasalestest');
        var_dump($response);
        exit;
    }
}

正如我提到的，我可以通过浏览器很好地访问这个端点，并且可以在终端中使用 cURL 直接访问它，只要我使用 -k 标志来表示“不安全”。我不确定我还能做什么，因为 Guzzle 的文档对 5 和 6 之间的语法差异不是很清楚。然后 Drupal 和 Laravel 人群往往会遇到不相关的问题。

这个 SO 帖子看起来很相似(减去硬编码端口号和 Guzzle v.5)但没有提到任何我没有尝试过的东西:PHP Guzzle 5: Cannot handle URL with PORT number in it .

这个问题也很有趣，但基于与 App 1 交互的其他应用程序，它确实允许其他应用程序使用某些 API 端点:cURL error 7: Failed to connect to maps.googleapis.com port 443

此时我能想到的可能是 nginx 配置问题？朝着正确的方向插入是我向前迈进并获得我需要消费的其余端点所需要的。

感谢您的指导!

最佳答案

问题是本地计算机上的主机文件不会影响 docker 实例将 IP 映射到主机的方式。

尝试通过容器名称访问端点...
