$oldcontent = file_get_contents('notifications.txt');

$newnotsfile = fopen("notifications.txt", "w");

$post = file_get_contents('php://input');
$requestBody = json_decode($post , TRUE); //convert JSON into array

$time = date("Y-M-d H:i:s", time());
fwrite($newnotsfile , "<br><br>---------------- │ Time: ".$time."<br><br>");

foreach (getallheaders() as $name => $value) {
    fwrite($newnotsfile , $name.": ".$value."<br>");
} 

fwrite($newnotsfile , $requestBody );
fwrite($newnotsfile , "<br><br>");

fwrite($newnotsfile , $oldcontent);
fclose($newnotsfile );

?>

我认为通过使用$post=file_get_contents('php://input')；，我可以捕获请求正文，但事实是它什么也没有捕获。如果我理解正确，我应该收到一个结构在这里详细说明的变更资源。是我做错了什么，还是我理解错了？我很感激任何可以给予的洞察力和提前感谢！

实际上，没有在webhook通知中发送的请求正文。因此，一旦回调url中出现更改，将通过向更改资源uri发出如下所示的get请求来获取更改

Resource URI : https://www.googleapis.com/drive/v3/changes?includeRemoved=true&pageSize=100&pageToken=895&restrictToMyDrive=false&spaces=drive&alt=json

或者可以通过使用下面的代码获取编程更改

String pageToken = channelInfo.getCurrPageToken();
            List<Change> changes = service.changes().list(pageToken)
                    .execute().getChanges();

Google push notifications doc本可以清楚地提到这一点，而不是在请求正文中提到更改，这是造成混乱的原因
