Curl SMTP TLS 错误

Question

当我运行curl命令时它就起作用了。

但是当我在curl smtp-tls.c中运行示例时，我收到了错误。

这里是输出。

输出:

  Rebuilt URL to: smtp.office365.com:587/
  * Hostname was NOT found in DNS cache
  *   Trying 111.221.114.166...

  * Connected to smtp.office365.com (111.221.114.166) port 587 (#0)

请帮忙解决这个问题。

谢谢。

您必须没有为 smtp 服务器设置用户名\密码。 您需要执行以下操作:

curl_easy_setopt(curl, CURLOPT_USERNAME, "user");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "secret");
