我正在尝试使用以下代码通过curl命令连接到sendgrid，并使用foreach将结果发布到我的数据库。现在我的用户名和密码上的未定义索引错误，以及我的foreach上的无效参数。我相信我知道为什么我得到了foreach错误，我在代码中对它进行了评论，但我不确定通过web api的连接方面。感谢
*编辑 - 我想添加我的端点已设置，我可以通过ngroks web界面查看测试数据。
<?php
require_once('../functions.php');
session_start();
connect();
//Enable Connection to Event Notifications
$url = 'https://api.sendgrid.com/';
$user = $_SESSION["xxxxxxx"];
$pass = $_SESSION["xxxxxxx"];
$params = array(
'api_user' => $user,
'api_key' => $pass,
'name' => 'eventnotify' //API App Name
);
$request = $url . 'api/filter.activate.json'; //i believe the [module] and [action] is incorrect here.
// Generate first 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);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
// obtain response
$response = curl_exec($session);
curl_close($session);
$data = $response[file_get_contents("php://input")]; // Can i do this? Or do i just pass a $json variable?
$records = json_decode($data, true);
foreach ($records as $record) {
// Here, you now have each event and can process them how you like
echo getArray($record);
$email = isset($record['email']) ? $record['email'] : null;
$event = $record['event'];
$uid = $_POST['uid'];
$timestamp = $_POST['timestamp'];
$event_type = $_POST['event'];
$email_address = $_POST['email'];
$smtpid = $_POST['smtpid'];
$sg_event_id = $_POST['sg_event_id'];
$sg_message_id = $_POST['sg_message_id'];
$category = $_POST['category'];
$newsletter = $_POST['newsletter'];
$response = $_POST['response'];
$reason = $_POST['reason'];
$ip = $_POST['ip'];
$useragent = $_POST['useragent'];
$attempt = $_POST['attempt'];
$status = $_POST['status'];
$type = $_POST['type'];
$url = $_POST['url'];
$additional_arguments = $_POST['additional_arguements'];
$event_post_timestamp = $_POST['event_post_timestamp'];
$raw = $_POST['raw'];
$customer_id = $_POST['customer_id'];
insert("sendgrid_events", array("uid" => $uid,
"timestamp" => $timestamp,
"event" => $event_type,
"email" => $email_address,
"smtpid" => $smtpid,
"sg_event_id" => $sg_event_id,
"sg_message_id" => $sg_message_id,
"category" => $category,
"newsletter" => $newsletter,
"response" => $response,
"reason" => $reason,
"ip" => $ip,
"useragent" => $useragent,
"attempt" => $attempt,
"status" => $status,
"type" => $type,
"url" => $url,
"additional_arguments" => $additional_arguments,
"event_post_timestamp" => $event_post_timestamp,
"raw" => $raw,
"customer_id" => $customer_id)); //Unique Arguement to attach customer id on original outbound email? Yes
}
还是非常新的PHP，所以感谢你的帮助。
响应响应：在json_decode函数处理之后，是以数组形式从sendgid发布的POST数据吗？我仍然不太确定我做错了什么。我已将我的代码修改为以下内容，并且我在foreach之外的所有变量上获得了一个未定义的索引，并且对foreach本身进行了无效的争论......
<?php
require_once('../functions.php');
connect();
$data = file_get_contents("php://input"); // Can i do this? Or do i just pass a $json variable?
$records = json_decode($data, true);
$uid = $_POST['uid'];
$timestamp = $_POST['timestamp'];
$event_type = $_POST['event'];
$email_address = $_POST['email'];
$smtpid = $_POST['smtpid'];
$sg_event_id = $_POST['sg_event_id'];
$sg_message_id = $_POST['sg_message_id'];
$category = $_POST['category'];
$newsletter = $_POST['newsletter'];
$response = $_POST['response'];
$reason = $_POST['reason'];
$ip = $_POST['ip'];
$useragent = $_POST['useragent'];
$attempt = $_POST['attempt'];
$status = $_POST['status'];
$type = $_POST['type'];
$url = $_POST['url'];
$additional_arguments = $_POST['additional_arguments'];
$event_post_timestamp = $_POST['event_post_timestamp'];
$raw = $_POST['raw'];
$customer_id = $_POST['customer_id'];
foreach ($records as $record) {
insert("sendgrid_events", array("uid" => $uid,
"timestamp" => $timestamp,
"event" => $event_type,
"email" => $email_address,
"smtpid" => $smtpid,
"sg_event_id" => $sg_event_id,
"sg_message_id" => $sg_message_id,
"category" => $category,
"newsletter" => $newsletter,
"response" => $response,
"reason" => $reason,
"ip" => $ip,
"useragent" => $useragent,
"attempt" => $attempt,
"status" => $status,
"type" => $type,
"url" => $url,
"additional_arguments" => $additional_arguments,
"event_post_timestamp" => $event_post_timestamp,
"raw" => $raw,
"customer_id" => $customer_id)); //Unique Arguement to attach customer id on original outbound email? Yes
}
echo "POST Received";
答案 0 :(得分：1)
看起来你可能会错误地解释Event Webhook的方式。每次事件发生时，webhook POST的数据都会发送到您的端点（在这种情况下，就是您的PHP脚本）（例如某人打开您的电子邮件）。这一切都是实时发生的。 是您希望用于获取和存储活动的API。
但是，您的脚本也使用App/Filter Activation Endpoint。此端点打开和关闭Filter（也称为App）的使用。您只需要使用一次，以确保在事件发生时将数据发布到PHP脚本。但是，通过SendGrid's Web Interface激活它可能更容易。有关该应用程序的更多信息以及您可以使用和修改它的方法，请参阅app description page。
如果从脚本中删除cURL请求位，则只需从POST请求获取数据并存储即可。通过将脚本更改为以下内容，事情应该有效：
<?php
// All your boilerplate code
require_once('../functions.php');
connect();
// Get the raw POSTed data
$data = file_get_contents("php://input");
// Decode said data
$records = json_decode($data, true);
// Loop through the records
foreach ($records as $record) {
// Store the event
// Assume store_event does your data processing and inserting
store_event($record);
// You should be able to access any parameter of the event as so
// $record["email"];
// e.g.
echo $record["email"];
echo " had an email ";
echo $record["event"];
}
您的错误位于以下行，您在设置过滤器时尝试将输入POST作为API响应的关键字。由于它不存在，因此数据未定义，因此无法与foreach进行迭代。
// The "bad" code
$data = $response[file_get_contents("php://input")];
您可以看到working code example of the event webhook on SendGrid's Documentation。
