使用 PHPMailer 从 ionic 发送电子邮件时获取错误响应

Question

我正在尝试在 ionic 中创建一个重置密码页面，用户可以在其中输入他的电子邮件，以在我的应用程序中重置他的帐户密码。问题是我想从 php 发送回复，告诉用户电子邮件是否已发送到他的电子邮件，具体取决于从 php 发送到 ionic 的值。发生的事情是电子邮件已发送，但显示响应错误。

这是我的打字稿代码：

   async sendEmail() {
        var regEmail = /^([a-zA-Z0-9\.-_]+)@([a-zA-Z0-9-]+).([a-z]{2,20})$/;
        if (!regEmail.test(this.resetPasswordForm.value.email)) {
            this.showToast("Invalid email");
            return;
        }

        const loading = await this.load.create({
            message: 'Please wait...'
        });
        loading.present();
        this.auth.sendEmailVerification(this.resetPasswordForm.value).subscribe((data) => {
            console.log(data);
            if (data == "sent") {
                this.showAlert("Great!", "We have sent you an email, check your inbox.");
                this.resetPasswordForm.reset();
            }
            else if (data == "notfound") {
                this.showAlert("Error!", "This email was not found.");
            } else if (data == "error") {
                this.showAlert("Oupss!", "An error occured and email could not be sent.");
            }
        }, (err) => {
                console.log(err);
                this.showAlert("Error!", err.message);
        });
        loading.dismiss();
    }

php代码：

<?php
session_start();
require("headers.php");
require("connection.php");
$userData=file_get_contents("php://input");
$request=json_decode($userData);
$to=$request->email;

// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function

$con=connect();

$res=mysqli_query($con,$checkUser);
$row=mysqli_fetch_array($res);

if($row[0]==1){
// Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    $randomNumber=mt_rand(100000,999999);
    $_SESSION["random"]=$randomNumber;
    //Server settings
    $mail->SMTPDebug = 2;                      // Enable verbose debug output
    $mail->isSMTP();                                            // Send using SMTP
    $mail->Host       = 'smtp.gmail.com';                    // Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = '';                     // SMTP username
    $mail->Password   = '';                               // SMTP password
    $mail->SMTPSecure = 'tls';         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
    $mail->Port       = 587;                                    // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above

    //Recipients
    $mail->setFrom('no-reply@gmail.com','charbelalam755@gmail.com');
    $mail->addAddress($to);     // Add a recipient
    print json_encode("sent");

    // Attachments
   // $mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
   // $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name

    // Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = "Password reset email for account: ".$to;
    $mail->Body    = "Your confirmation code to reset your password is: ".$randomNumber;
    //$mail->AltBody =;
    $mail->send();



} catch (Exception $e) {
    print json_encode("error");
}
}else print json_encode("notfound");

mysqli_close($con);
?>

这是我遇到的错误：

我正在使用 print json_encode("") 从 php 向 ionic 发送响应，它在除此之外的任何地方都有效。

Answer 1

这是你的问题：

$mail->SMTPDebug = 2;

PHPMailer 的调试输出不 JSON 兼容，因此将其关闭：

$mail->SMTPDebug = 0;

您当然可以通过注入自己的调试输出回调将它变成 JSON，但我怀疑这就是您想要做的。

当调试这样的事情时，请始终在浏览器开发工具中查看您从服务器获得的实际响应——如果您查看过，您会在响应中看到 PHPMailer 调试输出。
