Question

如何使用Sendgrid发送邮件，我已经尝试了很多次，但是给出了错误信息，找不到类之类的错误，我也已经安装了作曲家，但我听不懂，请给我解决方案错误图片：

require './vendor/autoload.php';
include_once('credentials.php');
$FROM_EMAIL = 'from@gmail.com';
$TO_EMAIL = 'to@gmail.com';
$subject = "test";
$from = new SendGrid\Email(null, $FROM_EMAIL);
$to = new SendGrid\Email(null, $TO_EMAIL);
$htmlContent = '<!DOCTYPE html><html><head><title></title></head><body><p>hi this is test</p></body></html>';
$content = new SendGrid\Content("text/html",$htmlContent);
$mail = new SendGrid\Mail($from, $subject, $to, $content);
$sg = new \SendGrid($API_KEY);
$response = $sg->client->mail()->send()->post($mail);
if ($response->statusCode() == 202) 
{
    echo 'done';
} 
else 
{
    echo 'false';
}

遇到相同的问题，您必须在SendGrid\Email前面加上反斜杠\：

$from = new \SendGrid\Email(null, $FROM_EMAIL);
$to = new \SendGrid\Email(null, $TO_EMAIL);
