Mailgun Laravel 发送电子邮件错误 客户端错误消息

在 Laravel 5.1 上设置 mailgun 后，我确实收到错误消息：

客户端错误响应 [url]https://api.mailgun.net/v3//messages.mime https://api.mailgun.net/v3//messages.mime[状态代码] 404 [原因短语] 未找到

我在 mailgun 上创建了一个帐户。

编辑config/services.php

咕咕已安装

编辑 .env（mail_driver、mail_from、mail_nam、mailgun_domain 和 mailgun_secret）

我将 DNS 记录检查到 mailgun 仪表板并进行了验证。

有什么修复可以开始使用 laravel 和 mailgun 发送电子邮件吗？

造成这种情况的主要原因是环境变量配置错误。更新您的 config/mail.php 文件。替换变量值env('varname', 'value') to 'value'.

这是一个例子（为我工作！）：
