我进行了搜索,并阅读了http://docs.guzzlephp.org/en/stable/request-options.html处的文档,并确认了https://curl.haxx.se/libcurl/c/libcurl-errors.html处的错误,并且对我而言,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通过终端通过cURL来访问它们.

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
Nginx Reverse Proxy

nginx配置：

应用程序1和应用程序2已启用具有自签名证书的SSL,该证书是在docker-compose创建时导入的.

App 1有多个API端点App 2需要访问.当我尝试通过Guzzle访问时,我收到：

0.3521    4321000  10. GuzzleHttpPromiseRejectedPromise->wait() /var/www/app/vendor/guzzlehttp/guzzle/src/Client.php:131

这是我当前实现客户端的方式(包括为解决此问题而添加的一些代码)：

<?php
namespace ControllersApi;

use GuzzleHttpClient;
// use GuzzleHttpPsr7Uri;

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,我可以很好地通过浏览器访问此端点,并且可以在终端中使用cURL直接访问它,只要我将-k标志用于“不安全”即可.我不确定我还能做些什么,因为Guzzle的文档对5和6之间的语法差异还不太清楚.然后Drupal和Laravel人群往往会遇到不相关的问题.

这样的SO帖子看起来很相似(减去了硬编码的端口号和Guzzle v.5),但没有提及我没有尝试过的任何内容：PHP Guzzle 5: Cannot handle URL with PORT number in it.

这个问题也很有趣,但是基于与应用程序1交互的其他应用程序,它的确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

在这一点上,我能想到的只是nginx配置问题？我需要朝着正确的方向前进,并获得需要消耗的其余端点.

感谢您的指导！

最佳答案

事实证明,这是一个相对简单的解决方案.问题是两个fpm容器彼此不认识,并且通过在app-two的请求中引用app-one.local,app-two基本上将请求发送到了void中.修复方法如下：

version: '3.3'
services:
  nginx:
    image: evild/alpine-nginx:1.9.15-openssl
    container_name: nginx
    volumes:
      - ./app-one:/var/www/app-one/:ro
      - ./app-two:/var/www/app-two/:ro
      - ./nginx/conf/nginx.conf:/etc/nginx/conf/default.conf:ro
      - ./nginx/conf.d:/etc/nginx/conf.d:ro
      - ./certs:/etc/nginx/certs
    ports:
      - 80:80
      - 443:443
    expose:
      - "80"
      - "443"
    depends_on:
      - app-one
      - app-two
    environment: 
      TZ: "America/Los_Angeles"
    # This is the fix
    networks:
      default:
        aliases:
          - app-one.local
          - app-two.local

  app-one:
    environment: 
      TZ: "America/Los_Angeles"
    image: joebubna/php
    container_name: app-one
    restart: always
    volumes:
      - ./app-one:/var/www/app-one
    ports:
      - 9000:9000
    # This is the fix
    networks:
      - default

  app-two:
    environment: 
      TZ: "America/Los_Angeles"
    image: joebubna/php
    container_name: app-two
    restart: always
    volumes:
      - ./app-two:/var/www/app-two
    ports:
      - 9001:9000
    # This is the fix
    networks:
      - default

  db:
    image: mysql:5.6
    container_name: mysql
    volumes:
      - db-data:/var/lib/mysql
      - ./mysql/my.cnf:/etc/mysql/conf.d/ZZ-mysql.cnf:ro
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_USER: user
      MYSQL_PASSWORD: password
      MYSQL_DATABASE: cora
      TZ: "America/Los_Angeles"
    ports:
      - 3306:3306
    expose:
      - "3306"
    # This is the fix
    networks:
      - default

volumes:
  db-data:
# This is the fix
networks:
  default:
    driver: bridge

我最终要做的是创建一个覆盖网络,并使Nginx容器知道每个fpm的域名.这使两个容器现在可以通过FQDN在彼此之间来回发送请求,而不是IP或容器ID /名称.在事后看来,这是一件容易忽视的事情.
