如何使用带有 cURL 的 php 中的 google gmail api 发送电子邮件？

Question

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);

但我收到这样的错误消息：

{ "error": { "errors": [ { "domain": "global", "reason": "badContent", "message": "不支持媒体类型 'application/json'。有效的媒体类型: [message/rfc822]" } ], "code": 400, "message": "不支持媒体类型'application/json'。有效媒体类型：[message/rfc822]" } }

当我尝试使用时：

'Content-Type: message/rfc822';

我有一条新的错误信息：

{ "error": { "errors": [ { "domain": "global", "reason": "invalidArgument", "message": "需要收件人地址" } ], "code": 400, " message": "需要收件人地址" } }

我不想使用 google 提供的库。

看起来您正在发送 JSON 编码数据，而您应该尊重 message/rfc822 format。

您可能不应该 base64-encode + json-encode 您的消息：

<?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);
