我正在使用SendGrid通过HTML表单发送电子邮件。 HTML对我来说看起来正确，PHP对我也正确，但是当我单击“提交”按钮时，我被定向到仅显示Cannot POST /sendmail.php的页面。我是PHP新手，但是代码看起来正确。
在错误消息/页面的控制台中，有两个错误。
[第一个这样说：Refused to execute inline script because it violates the following Content Security Policy directive: "default-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-ThhI8UaSFEbbl6cISiZpnJ4Z44uNSq2tPKgyRTD3LyU='), or a nonce ('nonce-...') is required to enable inline execution. Note also that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
[第二个说：Refused to load the font '<URL>' because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback.
这些错误消息是否相关？
[我还应该提到我正在NodeJS服务器上运行表单。在本地主机上运行时，邮件脚本能工作吗？这是我的HTML：
<!DOCTYPE html>
<html>
<body>
<form name="form" action="sendmail.php" method="POST">
<input type="text" name="name" placeholder="name">
<input type="text" name="email" placeholder="email">
<input type="text" name="message" placeholder="message">
<button name="submit" type="submit">Submit</button>
</form>
</body>
</html>
这是我的PHP
<?php
/*SendGrid Library*/
require 'vendor/autoload.php';
if (isset($_POST['submit'])) {
/*Post Data*/
$user_name = $_POST['name'];
$user_email = $_POST['email'];
$user_message = $_POST['message'];
/*Content*/
$email = new \SendGrid\Mail\Mail();
$email->setFrom("$user_email", "$user_name");
$email->setSubject("Send Email Attachments with Twilio SendGrid");
$email->addTo("[email protected]", "Example User");
$email->addContent(
"text/html",
"How easy can this be?"
);
$sendgrid = new \SendGrid(getenv('SENDGRID_API_KEY'));
/*Response*/
try {
$response = $sendgrid->send($email);
print $response->statusCode() . "\n";
print_r($response->headers());
print $response->body() . "\n";
} catch (Exception $e) {
echo 'Caught exception: '. $e->getMessage() ."\n";
}
}
?>
所有相关问题对我不是很有帮助。谢谢
很明显，您的问题出在CSP（内容安全策略）上。
