PHPMailer没有发送，没有给出错误抛出500错误

Question

更新：这是我收到的错误：SMTP 连接（）失败。 致命错误：未捕获的异常 'phpmailerException' 带有消息 'SMTP connect() failed。'

我正在使用一个名为 Frameworx 的预先存在的 php 框架。一切都很棒，但它不会发送电子邮件，我认为这是因为我使用的是 OpenShift，而且他们对邮件服务器非常严格。我需要使用 SendGrid，所以我试图使用 PHPMailer 来做到这一点。也许我对这一切都错了。但基本上，当我尝试发送邮件时，我得到的只是一个空白页。用户已创建。

这就是我所拥有的：

        // Create a New Account Form
    if (isset($_POST['submit']) && $_POST['submit'] == 'newAccount') {
        // User Validations
        if($_POST['usersName'] == '') {
            $msgBox = alertBox("Your First and Last Name is required.", "<i class='fa fa-times-circle'></i>", "danger");
        } else if($_POST['usersEmail'] == '') {
            $msgBox = alertBox("A valid Email Address is required.", "<i class='fa fa-times-circle'></i>", "danger");
        } else if($_POST['password'] == '') {
            $msgBox = alertBox("A New Account Password is required.", "<i class='fa fa-times-circle'></i>", "danger");
        } else if($_POST['password'] != $_POST['passwordr']) {
            $msgBox = alertBox("Passwords do not match, please check your entries.", "<i class='fa fa-times-circle'></i>", "danger");
        // Black Hole Trap to help reduce bot registrations
        } else if($_POST['captcha'] != '') {
            $msgBox = alertBox("An Error was encountered and the New Account could not be created.", "<i class='fa fa-times-circle'></i>", "danger");
        } else {
            // Set some variables
            $dupEmail = '';
            $newEmail = $mysqli->real_escape_string($_POST['usersEmail']);

Answer 1

看起来您正在尝试通过SMTP（Simple Mail Transfer Protocol）发送，但是，您将 SendGrid 的 Web API 域作为主机名传递。因此，当 phpmailer 尝试连接到“域”https://api.sendgrid.com/ 时，它会失败。

要解决此问题，请更改此行：

$mail->Host = 'https://api.sendgrid.com/';  // Specify main and backup SMTP servers

收件人：

$mail->Host = 'smtp.sendgrid.net';  // Specify main and backup SMTP servers

Answer 2

$mail->IsMail();

你必须使用这个
