Sendgrid Azure PHP | 易学教程

问题

I am a newbie to php, azure, and sendgrid.

here is some code I found that I am trying to use for the html form.

<!-- BEGINNING OF CONTACT FORM -->
<div class="section-page-landing" id="contact">
			<div class="inner-section">
				<div class="contain">
					<center><h2>Contact Me</h2>
<form class="contact" action="a_test_mailer_processor.php" method="post">
<p>Name:</p> <!-- Can choose to customize form.html inputs starting here as needed, but be sure to reference any changes in mailer.php post fields-->
<input type="text" name="name" />
 <p>E-mail:</p>
<input type="text" name="email" />
<p>Subject:</p>
<input type="text" name="subject" />
<p>Message:</p>
<textarea name="message" syle="width: 45%; text-align: center;">Please leave a short message here</textarea></p>
<input class="send" type="submit" value="Send"> <!-- Send button-->
</form></center>
				</div>
			</div>
		</div>
		<!--end contact form-->

Here is the PHP I am trying to use

I updated the code as follows, swapping out my credentials and email address. No errors but still not working for me. Is there something else I can test?

<?php

ini_set('error_reporting', E_ALL);
ini_set('display_errors', 1);
var_dump(function_exists('curl_version'));

$url = 'https://api.sendgrid.com/';
$user = 'MYSENDGRIDUSERNAME';
$pass = 'MYSENDGRIDPASSWORD';

$params = array(
    'api_user'  => $user,
    'api_key'   => $pass,
    'to'        => 'MYEMAILADDRESS',
    'subject'   => 'testing from curl',
    'html'      => 'testing body',
    'text'      => 'testing body',
    'from'      => 'MYEMAILADDRESS',
  );


$request =  $url.'api/mail.send.json';

// Generate curl request
$session = curl_init($request);
// Tell curl to use HTTP POST
curl_setopt ($session, CURLOPT_POST, true);
// Tell curl that this is the body of the POST
curl_setopt ($session, CURLOPT_POSTFIELDS, $params);
// Tell curl not to return headers, but do return the response
curl_setopt($session, CURLOPT_HEADER, false);
// Tell PHP not to use SSLv3 (instead opting for TLS)
curl_setopt($session, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

// obtain response
$response = curl_exec($session);
curl_close($session);

// print everything out
print_r($response);

?>

And here are the errors I am getting. bool(true) Notice: Undefined variable: curl in D:\home\site\wwwroot\a_test_mailer_processor.php on line 36 Warning: curl_setopt() expects parameter 1 to be resource, null given in D:\home\site\wwwroot\a_test_mailer_processor.php on line 36

I tried simply removing line 36, curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2); and the errors stopped but the form still did not get sent/received. Let me know what I am doing wrong.

As you hadn’t defined $curl before setting parameters using curl_setopt, and here is a code sample on SendGrid code examples page, please try it:

<?php

$url = 'https://api.sendgrid.com/';
$user = 'USERNAME';
$pass = 'PASSWORD';

$params = array(
    'api_user'  => $user,
    'api_key'   => $pass,
    'to'        => 'example3@sendgrid.com',
    'subject'   => 'testing from curl',
    'html'      => 'testing body',
    'text'      => 'testing body',
    'from'      => 'example@sendgrid.com',
  );


$request =  $url.'api/mail.send.json';

// Generate curl request
$session = curl_init($request);
// Tell curl to use HTTP POST
curl_setopt ($session, CURLOPT_POST, true);
// Tell curl that this is the body of the POST
curl_setopt ($session, CURLOPT_POSTFIELDS, $params);
// Tell curl not to return headers, but do return the response
curl_setopt($session, CURLOPT_HEADER, false);
// Tell PHP not to use SSLv3 (instead opting for TLS)
curl_setopt($session, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

// obtain response
$response = curl_exec($session);
curl_close($session);

// print everything out
print_r($response);

?>

--Update--

If you get error message as not defined constant CURL_SSLVERSION_TLSv1_2, we can directly set integer variable to CURLOPT_SSLVERSION. We can find details in http://php.net/manual/en/function.curl-setopt.php:

One of CURL_SSLVERSION_DEFAULT (0), CURL_SSLVERSION_TLSv1 (1), CURL_SSLVERSION_SSLv2 (2), CURL_SSLVERSION_SSLv3 (3), CURL_SSLVERSION_TLSv1_0 (4), CURL_SSLVERSION_TLSv1_1 (5) or CURL_SSLVERSION_TLSv1_2 (6).

set as: curl_setopt($session, CURLOPT_SSLVERSION, 6);

And I have to set an additional option :

curl_setopt($session, CURLOPT_SSL_VERIFYPEER, false);

so that I can succeed to set my request to SendGrid Server.
