抛出ErrorException，并显示消息“出于安全原因，mail()已被禁用

Question

我正在尝试设置一个 Laravel 网站，我已经能够完成一些工作，但随后我遇到了这个错误。

出于安全原因，mail() 已被禁用

我曾尝试联系我的托管提供商来协助激活该功能，但他们让我大吃一惊，说他们无法激活该功能，我应该尝试修改邮件程序的标头，这样就不需要这样做了。

请问我该如何做到这一点，因为我不是邮件 php 方面的专家。

这是我的错误：

ErrorException thrown with message "mail() has been disabled for security reasons"

Stacktrace:
#57 ErrorException in /home/zcashcom/public_html/invest/core/app/Http/helpers/helpers.php:19
#56 mail in /home/zcashcom/public_html/invest/core/app/Http/helpers/helpers.php:19

Answer 1

如果邮件出于安全原因被停用，那么您不应使用它。事实上，如果你用谷歌搜索这个主题，你会发现一些严重的结果，为什么你不应该使用它。

我希望您拥有托管服务商的电子邮件帐户，对吧？那么你有什么理由不想使用 Laravel 的邮件功能呢？

在您的 .env 文件中，为您的电子邮件帐户设置正确的参数：

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=ssl

有时您还需要定义MAIL_FROM_ADDRESS参数。如果您不确定是否在配置的 mail.php 文件中找到了所有可能的配置选项。

然后要使用 Laravel 发送电子邮件，您可以执行以下操作

Mail::raw('your message', function ($message) use ($request) {

    $message->to('[email protected]');
    $message->from('[email protected]');
    $message->subject("Email subject");
});

我不知道你想实现什么，但如果你只想发送一些简单的信息，也许你应该使用 laravel 通知。

Answer 2

嗯，这实际上是另一个问题。 helpers.php 文件位于哪里？是在app文件夹下吗？以及它是如何包含在内的？您从错误中看到 php 命名空间是当前命名空间下的函数，所以我猜文件的包含/自动加载方式有问题？我的helpers.php 文件位于应用程序文件夹中，然后通过composer（在composer.json 中）加载它。它看起来像这样：

"autoload": {
    "files": [
        "app/helpers.php"
    ],
    "psr-4": {
        "App\\": "app/"
    },
    "classmap": [
        "database/seeds",
        "database/factories"
    ]
},

如果更改该文件，则必须运行

composer dump-autoload

...如果文件看起来已经像这样，运行命令也没有什么坏处，因为可能出了问题。
