Question

我的网站上有一个mailer.php，它与sendgrid连接，向我们发送查询表格中的电子邮件。但是，在我们的设置中，当有人在问题中输入电子邮件时，他们会在点击发送时收到错误页面。具有讽刺意味的是，电子邮件仍然会被发送，但它并没有将它们发送到我们服务器上的成功页面。

以下是您收到的错误消息。

警告：curl_setopt（）期望参数1为资源，在第35行的/home/dekastud/public_html/mailer.php中给出null

警告：无法修改标题信息 - 已在第53行的/home/dekastud/public_html/mailer.php中发送的输出（/home/dekastud/public_html/mailer.php:1上的输出）

Answer 1

删除PHP文件顶部的空格。 <?php之前的那些空格实际上将输出发送到浏览器。将某些内容输出到浏览器后，您就无法发送标题。

header("Location: ...");

正在发送标题......

此外，在拨打curl_setopt()之前，您有一个curl_init()来电，这是无效的。 curl_setopt()需要有效的curl资源。请参阅here。

curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);应低于curl_init()的调用，$curl变量应替换为有效的curl资源，或者在您的情况下$session。
