Codeigniter 和 Mandrill api，无法发送电子邮件

Question

我正在尝试通过将 Mandrill 与 CodeIgniter 一起使用来发送电子邮件。我可以按照他们的文档中的描述使用 Mandrill API：

require_once(mandrill/Mandrill.php);

$Mandrill = new Mandrill($apikey);

$params = array(
    "html" => "<p>\r\n\tHi Adam,</p>\r\n<p>\r\n\tThanks for <a    href=\"http://mandrill.com\">registering</a>.</p>\r\n<p>etc etc</p>",
    "text" => null,
    "from_email" => "xxx@xxx.example.com",
    "from_name" => "chris french",
    "subject" => "Your recent registration",
    "to" => array(array("email" => xxx@yyy.example.com")),
    "track_opens" => true,
    "track_clicks" => true,
    "auto_text" => true
);

$Mandrill->messages->send($params, true));

这很简单，但是当我尝试通过 CodeIgniter 发送 Mandrill 邮件时，我得到了错误结果；这是我的代码：

$this->load->library('mandrill/Mandrill');
$this->Mandrill->apikey($apikey);
//...
//All other options
$this->Mandrill->messages->send($params, true));

库正在成功加载，发送电子邮件是我收到错误的地方。

抛出错误：

Fatal error: Call to a member function send() on null

我猜你错误地加载了 mandrill 类以使其成为“CodeIgniter 方式”，如下所示：

1. 放类（mandrill.php and folder mandrill文件夹中的文件application/libraries）见图
2. 使用$this->load->library('mandrill', array($apikey));加载类
3. 修正$params中的所有错别字（你缺少"，最后一行有两个括号))最后）
4. 修改mandrill.php，使其在构造函​​数中接受数组作为参数；请参阅解决方案部分答案
5. 在 Mandrill 的教程中使用 API（发送、ping...随便）

有效代码

$this->load->library('mandrill', array($apikey)); //load mandrill and provide apikey

$params = array(
        "html" => "<p>\r\n\tHi Adam,</p>\r\n<p>\r\n\tThanks for <a    href=\"http://mandrill.com\">registering</a>.</p>\r\n<p>etc etc</p>",
        "text" => null,
        "from_email" => "xxx@xxx.example.com",
        "from_name" => "chris french",
        "subject" => "Your recent registration",
        "to" => array(array("email" => "xxx@yyy.example.com")),
        "track_opens" => true,
        "track_clicks" => true,
        "auto_text" => true
    );

$this->mandrill->messages->send($params, true);

编辑（cmets）

请注意：我删除了真正的 api-key = MY_KEY，电子邮件来自 = EMAIL_FROM，电子邮件至 = EMAIL_TO

$msg = array(
    "html" => "The Message",
    "text" => null,
    "from_email" => "EMAIL_FROM",
    "from_name" => "John Doe",
    "subject" => "Acme",
    "to" => array(array("email" => "EMAIL_TO")),
    "track_opens" => true,
    "track_clicks" => true,
    "auto_text" => true
);

require_once APPPATH.'libraries/Mandrill.php';
$mandrill = new Mandrill('MY_KEY');
var_dump($mandrill->messages->send($msg, true));
//var_dump($mandrill->users->ping());


$this->load->library('Mandrill', array("MY_KEY")); //load mandrill and provide apikey
var_dump($this->mandrill->messages->send($msg, true));
//var_dump($this->mandrill->users->ping());

以上代码两次发送相同的电子邮件（使用不同的加载方法）；回复 && 少数var_dump() 是：

使用require_once...的方法

object(Mandrill)[14] //setup
  public 'apikey' => string 'MY_KEY' (length=22)
  public 'ch' => resource(40, curl)
  public 'root' => string 'https://mandrillapp.com/api/1.0/' (length=32)
  public 'debug' => boolean false

array (size=1) //this is response
  0 => 
    array (size=4)
      'email' => string 'EMAIL_TO' (length=24)
      'status' => string 'sent' (length=4)
      '_id' => string 'f7af72b1e1364a58a2eb302e94a1dc1e' (length=32)
      'reject_reason' => null

使用$this->load->library();的方法

object(Mandrill)[30] //setup
  public 'apikey' => string 'MY_KEY' (length=22)
  public 'ch' => resource(41, curl)
  public 'root' => string 'https://mandrillapp.com/api/1.0/' (length=32)
  public 'debug' => boolean false

array (size=1) //this is response
  0 => 
    array (size=4)
      'email' => string 'EMAIL_TO' (length=24)
      'status' => string 'sent' (length=4)
      '_id' => string '5965091637fa42dd98b40a934523022e' (length=32)
      'reject_reason' => null

解决方案

为了让它工作，我改变了在 Mandrill 构造函数中检索 API_KEY 的方式，因为 CodeIgniter 的加载器将参数发送到构造函数为 array()

山魈.php

public function __construct($apikey=null) {
    if(is_array($apikey)) $apikey = $apikey[0]; //added this line
    if(!$apikey) $apikey = getenv('MANDRILL_APIKEY');
    if(!$apikey) $apikey = $this->readConfigs();
//... rest of the file

另一个选项是CI-Mandrill，注意它使用的是1.0版本；安装时间 ~5 分钟或更短
