PHP致命错误：未捕获的Swift_TransportException：无法与主机ssl：//smtp.gmail.com建立连接：stream_socket_client（）

Question

我正在使用带有 cmd 的 Windows 10。

当我使用 php index.php 启动我的 index.php 文件时，我收到了这个错误：

PHP Fatal error:  Uncaught Swift_TransportException: Connection could not be established with host ssl://smtp.gmail.com :stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed in C:\Users\barte\Desktop\PHP\3\vendor\swiftmailer\swiftmailer\lib\classes\Swift\Transport\StreamBuffer.php:269 Stack trace:

我的 index.php 文件：

<?php

require "vendor/autoload.php";

$transport = new Swift_SmtpTransport("ssl://smtp.gmail.com", 465);
$transport->setUsername("mymail");
$transport->setPassword("******");

$mailer = new Swift_Mailer($transport);

$message = new Swift_Message();
$message
    ->setFrom("mymail@gmail.com")
    ->setTo("mymail@gmail.com")
    ->setSubject("Hello!")
    ->setBody("Hello, this is example body");

$mailer->send($message);

这是我的 composer.json 文件：

{
    "name": "bartek/3",
    "authors": [
        {
            "name": "Bartek",
            "email": "mymail@gmail.com"
        }
    ],
    "require": {
        "swiftmailer/swiftmailer": "^6.2"
    }
}

当我输入 composer --version 时，我得到：

PHP 临时目录 (C:\Users\barte\AppData\Local\Temp) 不存在 或者对 Composer 是不可写的。在 php.ini 中设置 sys_temp_dir Composer 版本 1.10.5 2020-04-10 11:44:22

谢谢

我最近为此准备了代码 对于 TLS

$transport = (new Swift_SmtpTransport('smtp.gmail.com', 587,'tls'))
->setUsername('username@gmail.com')
->setPassword('password');

并且对于 SSL

$transport = (new Swift_SmtpTransport('smtp.gmail.com', 25,'ssl'))
->setUsername('username@gmail.com')
->setPassword('password');

我解决了。问题是，我输入了我的 Google 帐户的密码，但我应该将在“应用程序密码”中生成的密码粘贴到那里的 google 帐户设置中。你可以去Google Account Settings > Security > App passwords生成这样的密码

注意：您必须先启用两步验证。否则App passwords 不会出现。

ssl://smtp.gmail.com 不是邮件服务器的正确地址。如果您跳过协议而只使用smtp.gmail.com 会发生什么？
