c-卷曲SMTP TLS错误

Question

当我运行curl命令时，它会起作用。

但是当我在curlsmtp-tls.c中运行示例时，我得到了错误。

这是输出。

输出：

  *   Trying 111.221.114.166...

请帮忙解决这个问题。

谢谢。

您一定没有为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");

请参阅文档：https://curl.haxx.se/libcurl/c/smtp-tls.html
