curl 通过 gmail 发送电子邮件

  • 772

新的攻击。一个大约两个月前通过 GMail 自动发送电子邮件的程序，使用

smtps://smtp.gmail.com:465

现在不起作用。是的，它是很久以前推出的，但我登录了 GMail 帐户 - 允许第三方应用程序。

现发行

他不喜欢什么？我究竟做错了什么？GMail 有什么变化吗？登录密码未更改。

换句话说，迷茫...

    您不仅切换到不同的端口，而且切换到不同的协议。

    根据curl 网站上的代码，您应该使用类似的 url

    smtp://mainserver.example.net:587

    并设置一些选项：

    curl_easy_setopt(curl, CURLOPT_USE_SSL, (long)CURLUSESSL_ALL);

    如果您没有证书（）并且从问题来看，它没有）

    curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);
