我遇到了让PHP连接到SendGrid（使用他们的库）并发送消息的问题。每当我单击表单上的提交按钮向我发送消息时，它都会像jQuery一样运行：
$("#contact-form").submit(function(e) {
e.preventDefault();
var c_name = $("#c_name").val();
var c_email = $("#c_email").val();
var c_message = $("#c_message ").val();
var responseMessage = $('.ajax-response');
if (( c_name== "" || c_email == "" || c_message == "") || (!isValidEmailAddress(c_email) )) {
responseMessage.fadeIn(500);
responseMessage.html('<i class="fa fa-warning"></i> Check all fields.');
}
else {
$.ajax({
type: "POST",
url: "assets/php/sendgrid-php/contactForm.php",
dataType: 'json',
data: {
c_email: c_email,
c_name: c_name,
c_message: c_message
},
beforeSend: function(result) {
$('#contact-form button').empty();
$('#contact-form button').append('<i class="fa fa-cog fa-spin"></i> Wait...');
},
success: function(result) {
if (result.sendstatus == 1) {
console.log(result);
responseMessage.html(result.message);
responseMessage.fadeIn(500);
$('#contact-form').fadeOut(500);
} else {
console.log(result);
console.log(c_name + " " + c_email + " " + c_message);
$('#contact-form button').empty();
$('#contact-form button').append('<i class="fa fa-retweet"></i> Please try again.');
responseMessage.html(result.message);
responseMessage.fadeIn(1000);
}
}
});
}
当它发布到URL时，它会运行到contactForm.php文件，该文件包含以下内容：
<?php
require 'sendgrid-php.php';
$sendgrid = new SendGrid('(my user)', '(my pass)', $options = array(
'turn_off_ssl_verification' => false,
'protocol' => 'https',
'host' => 'api.sendgrid.com',
'endpoint' => '/api/mail.send.json',
'port' => null,
'url' => null,
));
$email = new Sendgrid\Email();
try {
$email ->addTo('(my email)@outlook.com')
->setFrom($_POST['c_email'])
->setSubject("From Portfolio")
->setText($_POST['c_message']);
$response = $sendgrid->send($email);
if (!$response) {
throw new Exception("Did not receive response.");
} else if ($response->message && $response->message == "error") {
throw new Exception("Received error: ".join(", ", $response->errors));
} else {
$result = array(
'message' => 'Thanks for contacting us!',
'sendstatus' => 1
);
echo json_encode($result);
}
}
catch ( Exception $e ) {
$result = array(
'message' => 'There was an error sending the email',
'sendstatus' => 1
);
echo json_encode($result);
}
?>
require文件与contactForm.php位于同一文件夹中。无论我多少次尝试过各种事物，每次点击发送消息按钮时，我都会从Post请求中收到500错误。我不能为我的生活找出正在发生的事情。
完全披露，我对PHP来说相对较新，来自C＃和JS世界。 Haven已经能够弄清楚如何将错误发布到我的控制台，这是另一个问题 - 错误是我无法找到的错误。尝试了来自这些论坛的多个建议，以便发布错误（并解决问题），没有运气。伙计们，有什么想法？

<h3>HTTP Error 500.0 - Internal Server Error</h3>
<h4>The page cannot be displayed because an internal server error has occurred.</h4>

<div class="content-container">
<fieldset><h4>Most likely causes:</h4>
<ul> <li>IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.</li> <li>IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.</li> <li>IIS was not able to process configuration for the Web site or application.</li> <li>The authenticated user does not have permission to use this DLL.</li> <li>The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.</li> </ul>
</fieldset>
</div>
<div class="content-container">
<fieldset><h4>Things you can try:</h4>
<ul> <li>Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.</li> <li>Check the event logs to see if any additional information was logged.</li> <li>Verify the permissions for the DLL.</li> <li>Install the .NET Extensibility feature if the request is mapped to a managed handler.</li> <li>Create a tracing rule to track failed requests for this HTTP status code.

This error means that there was a problem while processing the request. The request was received by the Web server, but during processing a fatal error occurred, causing the 500 error.

答案 0 :(得分：0)
最终通过添加PHP Manager扩展来跟踪错误，更改端口以及添加SendGrid \ Email类的require行来解决此问题。一旦错误可见，这一切都变得如此简单。
啊......啊......那种爱讨厌的关系。不管怎么说，伙计们。感谢指向正确的方向。
