PHP尝试安全地发送邮件-找不到PHPMailer类 [英] PHP trying to send mail securely - cannot find the PHPMailer class

问题描述

我从以下内容开始:

composer require phpmailer/phpmailer

随后需要一次放置

require_once "../vendor/autoload.php";

然后

$mail = new PHPMailer;

这是PHP发生致命错误的地方:

That's where PHP has a fatal error:

致命错误:找不到类'PHPMailer'

Fatal error: Class 'PHPMailer' not found

以下是我的代码: 使用PHPMailer \ PHPMailer \ PHPMailer; 使用PHPMailer \ PHPMailer \ Exception;

The following is my code: use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\Exception;

# require php mailer
  require_once "../vendor/autoload.php";

  //PHPMailer Object
  $mail = new PHPMailer;

  $mail->isSMTP();
  $mail->SMTPDebug = 3; 
  $mail->SMTPAuth = true;
  // $mail->SMTPSecure = "ssl";
  $mail->SMTPSecure = "tls";
  $mail->Host = "smtp-relay.gmail.com";
  $mail->Port = "587";
  $mail->Username = "some gmail address";
  $mail->Password = "some password";
  $mail->SetFrom("[e-mail]");
  $mail->Subject = $subject;
  $mail->Body = $htmlMessage;
  $mail->AddAddress($recpEmails);
  $mail->Send();

$htmlMessage是一个既包含纯文本又包含带有mime_boundary的html的变量，但由于无法找到PHPMailer，因此它从未到达那里.

$htmlMessage is a variable containing both plain text and html with mime_boundary but it never gets there as it cannot find PHPMailer.

这是我试图解决此问题的方法:

This is what I have tried to do to fix the issue:

我在与供应商相同的目录中创建了另一个名为PHPMailer的目录，该新目录包含phpmailer/phpmailer/src的内容，但仍然找不到PHPMailer类.

I have created another directory called PHPMailer in the same directory as vendor, this new directory containing the contents of phpmailer/phpmailer/src, but it still cannot find the PHPMailer class.

我还需要PHPMailer.php文件吗?我以为那应该是自动加载功能?

Do I have to require the PHPMailer.php file as well? I thought that was what the autoload was supposed to do?

预先感谢

@Phil在评论中指出我缺少使用名称空间后，我更新了代码，这导致了新的错误:

After @Phil in the comments pointed out that I was missing the use namespace, I have updated the code, which has lead to a new error:

致命错误:未捕获的异常'PHPMailer \ PHPMailer \ Exception'和消息'SMTP connect()失败

Fatal error: Uncaught exception 'PHPMailer\PHPMailer\Exception' with message 'SMTP connect() failed

我了解到$mail->SMTPDebug = 3;提供了更多细节，其中揭示了以下内容:

I read that $mail->SMTPDebug = 3; gives more details, which revealed the following:

然后我阅读另一篇文章更改以下设置，这使我看到它正在连接，但它不接受我的凭据:

I then read to on another post to change the following settings, which allowed me to see that it was connecting, but it was not accepting my credentials:

$mail->SMTPSecure = "tls";

我目前不知道该怎么办，因为我知道这些是我的gmail帐户的凭据.我必须有一个Gmail企业帐户或类似的东西吗?

I do not know what to do at this point, as I know these are the credentials for my gmail account. Do I have to have a gmail business account or something like that?

我使用了错误的密码.输入正确的密码后，我开始收到以下消息:

I was using incorrect password. Once I entered the correct password, I began receiving the following message:

原来，我必须有一个G-Suite帐户才能使用smtp-relay.gmail.com.我只有一个普通的Gmail帐户.当我更改为smtp.gmail.com时，我又回到了错误的凭据错误.我将等待我的G-Suite帐户得到验证，然后将结果更新.

Turns out that I have to have a G-Suite account to use smtp-relay.gmail.com. I only have a regular gmail account. When I changed to smtp.gmail.com, then I am back to the bad credentials errors. I will just wait for my G-Suite account to be verified and I will update with the results.

推荐答案

尝试添加

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

在文件顶部的

导入PHPMailer类.

at the top of your file to import the PHPMailer classes.
