Codeigniter表单电子邮件未发送

我正在尝试从我的codeigniter表单发送电子邮件。但我收到的是“发送邮件时出错！请稍后再试”。控制台中没有错误。这是我的控制器，有什么帮助吗

这和我的gmail帐户有什么关系吗

在配置中是否有错误消息，因为如果不设置它，它将显示实际的php错误。你在gmail上有两步认证吗？同时尝试将
'smtp\U crypto'=>'tls'
添加到配置中。@Mikeyhun-控制台中未显示任何错误。2步骤身份验证已关闭。添加配置，但没有机会：\n您在配置中是否有错误消息，因为如果不设置它，它将显示实际的php错误。你在gmail上有两步认证吗？同时尝试将
