MailGun附件未显示

Question

显示的电子邮件中没有附加任何文件。我在test/test.txt上有一个不能附加的文本文件。下面是一个简单的函数。使用时，电子邮件显示时不带附件：

function send_email_with_attachment($email,$name){
    $mgClient = new Mailgun(MAILGUN_KEY);
    $domain = "mg.example.com";

    $file = array(
        array(
            'filePath' => 'test',
            'filename' => 'test.txt'
        )
    );

    $result = $mgClient->sendMessage($domain,array(
        "from"    => "Company Support <support@example.com>",
        "to"      => "{$name}<{$email}>",
        "subject" => "File Attached",
        "text"    => "Here is a cool text file",
        'attachment' => json_encode($file)
    )); 
}

Answer 1

为什么不像这样直接使用附件：

$result = $mgClient->sendMessage($domain,array(
        "from"    => "Company Support <support@example.com>",
        "to"      => "{$name}<{$email}>",
        "subject" => "File Attached",
        "text"    => "Here is a cool text file",
        'attachment' => [
    ['filePath'=>'/test.txt', 'filename'=>'test']
  ]
    )); 

试着从官方代码中获取以下代码：

$mg->messages()->send('example.com', [
  'from'    => 'bob@example.com', 
  'to'      => 'sally@example.com', 
  'subject' => 'Test file path attachments', 
  'text'    => 'Test',
  'attachment' => [
    ['filePath'=>'/tmp/foo.jpg', 'filename'=>'test.jpg']
  ]
]);

Answer 2

这个问题与我对Mailgun如何显示示例filePath和filename变量值的困惑有关。

如上所述，这里有一个来自MailGun的例子：

$mg->messages()->send('example.com', [
  'from'    => 'bob@example.com', 
  'to'      => 'sally@example.com', 
  'subject' => 'Test file path attachments', 
  'text'    => 'Test',
  'attachment' => [
    ['filePath'=>'/tmp/foo.jpg', 'filename'=>'test.jpg'] //what? Which file is being sent?
  ]
]);

这里有几个值得我注意的地方：

1. 首先是我使用的是相对于php文件的路径，而不是我的服务器的根目录。
2. 第二是我不理解邮件枪的例子。在本例中，发送的是哪个文件？对我来说，这个例子可能会更清楚：

$mg->messages()->send('example.com', [
  'from'    => 'bob@example.com', 
  'to'      => 'sally@example.com', 
  'subject' => 'Test file path attachments', 
  'text'    => 'Test',
  'attachment' => [
    ['filePath'=>'/tmp/foo.jpg', 'filename'=>'foo.jpg'] //this is a better way to demonstrate
  ]
]);
