如何使用php中的google gmail api和cURL发送电子邮件？

我在Php和cURL中使用Google Api发送邮件时遇到问题

我试过这个：

// ENVOIE EMAIL

$message="To: test@example.com\r\nFrom: test@example.com\r\nSubject: GMail test.\r\n My message";
$email=base64_encode($message);

$url_email = 'https://www.googleapis.com/upload/gmail/v1/users/me/messages/send';

$curlPost = array(
    'raw' => $email,
);
$ch = curl_init();      
curl_setopt($ch, CURLOPT_URL, $url_email);      
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);      
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer '. $AccessToken, 'Accept: application/json','Content-Type: application/json'));    
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($curlPost));
$data = curl_exec($ch);
// $data = json_decode(curl_exec($ch), true);;
curl_close($ch);
echo '<br/><h2>Send email</h2>';
print_r($data);

我有一条新的错误消息：

{“error”：{“errors”：[{“domain”：“global”，“reason”：“invalidArgument”，“message”：“Recipient address required”}]，“code”：400，“message”：“Recipient address required”}

我不想使用谷歌提供的库。

看起来你在发送JSON编码的数据，但你应该尊重它

您可能不应该对消息进行base64 encode+json编码：

<?php
$message = "To: test@example.com\r\nFrom: test@example.com\r\nSubject: GMail test.\r\n My message";


$ch = curl_init('https://www.googleapis.com/upload/gmail/v1/users/me/messages/send'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Bearer $AccessToken", 'Accept: application/json', 'Content-Type: message/rfc822'));    
curl_setopt($ch, CURLOPT_POSTFIELDS, $message);
$data = curl_exec($ch);
