在女巫模式下可以使用 php api 读取电子邮件主题吗？

我做这段代码

// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Gmail($client);

// Print the labels in the user's account.
$user = 'me';


$results = $service->users_messages->listUsersMessages($user);
foreach($results as $mail){
  $optParamsGet['format'] = 'metadata'; // Display message in payload
  $message = $service->users_messages->get($user, $mail['id'],$optParamsGet);
  $objMessage = $message->getPayload();
  print_r($objMessage[18]['value']);
}

我发现很难将此 api 与 php 一起使用，因为没有关于该功能的任何文档。 我在哪里可以找到完整的文档？ (例如，我找到了 getPayload 函数，因为我在这里看到了一些示例)

谢谢

最佳答案

如果您查看使用常规 http 请求访问 API 时获得的基本响应，我认为很多事情会更加清晰。

我会list我的最新消息，然后get消息，并查看响应:

请求

maxResults = 1

GET https://www.googleapis.com/gmail/v1/users/me/messages?maxResults=1

响应

{
 "messages": [
  {
   "id": "150791be31ee4e7b",
   "threadId": "150791be31ee4e7b"
  }
 ],
 "nextPageToken": "05858850367051193217",
 "resultSizeEstimate": 2
}

请求

GET https://www.googleapis.com/gmail/v1/users/me/messages/150791be31ee4e7b

响应

这是一条典型消息的外观，各种库所做的一切都是为了使其更易于使用。 headers 将驻留在 payload 中，它是您要查找的 Subject-header。

没有获取特定 header 的功能，但实现起来并不难:

function getHeader($headers, $name) {
  foreach($headers as $header) {
    if($header['name'] == $name) {
      return $header['value'];
    }
  }
}

$results = $service->users_messages->listUsersMessages($user);
foreach($results as $mail){
  $message = $service->users_messages->get($user, $mail['id']);
  $headers = $message->getPayload()->getHeaders();
  $subject = getHeader($headers, 'Subject');
}
