Question

当我尝试使用Sendgrid的PHP库发送电子邮件时，出现502 Bad Gateway错误。我在下面附上了错误日志，

502 Array ( 
[0] => HTTP/1.1 502 Bad Gateway

我不知道我在哪里错，我按照SendGrid网站（以及Github）上的文档进行了跟踪。我已经在使用的代码下方附加了代码。

我已经尝试过在sendgrid-php的GitHub存储库中其他问题中发现的可能的故障排除方法。

<?php
  require("sendgrid/sendgrid-php.php");
  $email = new \SendGrid\Mail\Mail();
  $email->setFrom("noreply@mydomain.com", "Leads");
  $email->setSubject($_POST['school'] . " - Appointment");
  $tos = [
    "support@mydomain.com" => "Support",
    $_POST['email'] => $_POST['name']
  ];
  $email->addTos($tos);
  $email->addContent("text/html", "<p><strong>Name:</strong> {$_POST['name']}</p>");
  $email->addContent("text/html", "<p><strong>Email:</strong> {$_POST['email']}</p>");
  $email->addContent("text/html", "<p><strong>Mobile:</strong> {$_POST['mobile']}</p>");
  $email->addContent("text/html", "<p><strong>School:</strong> {$_POST['school']}</p>");
  $email->addContent("text/html", "<p><strong>Count:</strong> {$_POST['count']}</p>");
  $email->addContent("text/html", "<p><strong>Gender:</strong> {$_POST['gender']}</p>");
  $sendgrid = new \SendGrid('xxxxxxxxxxxxxxAPIKEYxxxxxxxxxxxxxxxx');
  try {
    $response = $sendgrid->send($email);
    print $response->statusCode() . "\n";
    print_r($response->headers());
    print $response->body() . "\n";
  } catch (Exception $e) {
    echo 'Caught exception: '. $e->getMessage() ."\n";
  }
?>

执行代码后应发送电子邮件。

Answer 1

SendGrid存在一些奇怪的问题。有时，API会在后端自动被软删除。为了使代码正常工作，我必须创建一个新的API密钥并重试。解决方案成功了。

注意 -GitHub中的一些问题指示使用发件人地址初始化构造函数，但这不是实际问题。解决方法是在仪表板上创建一个新的API密钥，直到 SendGrid调查了为什么将API进行软删除以便对API进行调用返回错误。
