php - Elastic Beanstalk 中的 PHP Mailer 类无法识别

问题描述

据我了解，如果您composer.json在根目录中包含一个文件并且不包含供应商文件，那么 Composer 将自动处理 JSON 指令中的库。

这composer.json文件是 PHPMailer Github 上当前的 51 行 json 文件，它位于我的 EB 根文件夹中，其中包含/public和.ebextensions

然后我有这个 PHP 脚本（public/phphead.php )，从 AWS 文档复制

// Import PHPMailer classes into the global namespace

// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// If necessary, modify the path in the require statement below to refer to the
// location of your Composer autoload.php file.
require '../vendor/autoload.php';

// requiring /vendor/autoload.php would throw a fatal error and so I presume this is where composer creates the vendor dir. no more fatal errors have been thrown and I have been looking to confirm this is the right location but I have only the lack of errors to make me think composer is found and working...
// ....
$mail = new PHPMailer(); //LINE 64 as per error log

EB 的错误日志输出：

PHP 致命错误：未捕获的错误：在 /var/app/current/public/phpHead.php:64\n 堆栈跟踪中找不到类 'PHPMailer\PHPMailer\PHPMailer'：\n#0 /var/app/current/public/index .php(3): include()\n#1 {main}\n 在第 64 行的 /var/app/current/public/phpHead.php 中抛出

我composer.json正在使用（与 PHPMailer 的composer.json文件相同，取自 GitHub）：

    "type": "library",
    "description": "PHPMailer is a full-featured email creation and transfer class for PHP",

解决方案

我没有使用过 EB，但基于您认为它会composer install在需要时运行的假设，您需要包含一个有效的composer.json.

您包括包的composer.json。因此，您正在安装 PHPMailer 的依赖项，而不是 PHPMailer 本身。

您需要为您的项目/应用程序创建自己的composer.json文件，在其中声明 PHPMailer 为您的应用程序的依赖项。

例如：

{
  "name": "your/app",
  "type": "project",
  "description": "",
  "license": "CC-0",
  "require": {
    "phpmailer/phpmailer": "~6.1"
    }
}

在任何情况下，您都应该离线尝试您的代码（包括原始依赖项安装），然后再将其上传到 EB。

如果您尝试composer install离线运行和运行项目，您会遇到同样的问题。在部署之前运行您的基本项目。
