我遇到了一個問題，在最後期限之後讓問題變得更糟。以下代碼已在我的舊Web服務器上成功運行。當它移動到亞馬遜EC2但是它會導致它被呼叫的頁面不能打開超出它（即它不工作）。我已確保993端口是開放的EC2但由於我是新的服務器設置我可能失去了一些東西：從EC2連接到Gmail
function downloadData($emailAddress, $reportUrl, $reportType)
{
$result = "error";
// DOWNLOAD DATA
// the max time allows for the email to download
set_time_limit(3000);
// connect to gmail with your credentials
$hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
$username = $emailAddress; # e.g [email protected]
$password = '*************';
// try to connect
$inbox = imap_open($hostname,$username,$password) or die('Cannot download information: ' . imap_last_error());
/* get all new emails. If set to 'ALL' instead
* of 'NEW' retrieves all the emails, but can be
* resource intensive, so the following variable,
* $max_emails, puts the limit on the number of emails downloaded.
*
*/
$emails = imap_search($inbox,'ALL');
// useful only if the above search is set to 'ALL'
$max_emails = 5;
// if any emails found, iterate through each email
if($emails)
{
$count = 1;
// put the newest emails on top
rsort($emails);
// for every email...
foreach($emails as $email_number)
{
// get information specific to this email
$overview = imap_fetch_overview($inbox,$email_number,0);
// get mail message
$message = imap_fetchbody($inbox,$email_number,2);
// get mail structure
$structure = imap_fetchstructure($inbox, $email_number);
$attachments = array();
// if any attachments found...
if(isset($structure->parts) && count($structure->parts))
{
for($i = 0; $i < count($structure->parts); $i++)
{
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => ''
);
if($structure->parts[$i]->ifdparameters)
{
foreach($structure->parts[$i]->dparameters as $object)
{
if(strtolower($object->attribute) == 'filename')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['filename'] = $object->value;
}
}
}

foreach($structure->parts[$i]->parameters as $object)

$attachments[$i]['name'] = $object->value;
}
}
}
if($attachments[$i]['is_attachment'])
{
$attachments[$i]['attachment'] = imap_fetchbody($inbox, $email_number, $i+1);
// 4 = QUOTED-PRINTABLE encoding
if($structure->parts[$i]->encoding == 3)
{
$attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
}
// 3 = BASE64 encoding
elseif($structure->parts[$i]->encoding == 4)
{
$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
//imap_delete($inbox,$email_number);
imap_mail_move($inbox, $email_number,'[Gmail]/Bin');
}
}
}
// iterate through each attachment and save it
foreach($attachments as $attachment)
{
if($attachment['is_attachment'] == 1)
{
// SCAN REPORT SET OUTSIDE OF FUNCTION
$filename = $reportUrl;
if(empty($filename)) $filename = $attachment['filename'];
if(empty($filename)) $filename = time() . ".dat";
/* prefix the email number to the filename in case two emails
* have the attachment with the same file name.
*/
$fp = fopen($filename, "w+");
fwrite($fp, $attachment['attachment']);
fclose($fp);
$result = "success";
}
}
if($count++ >= $max_emails) break;
}
}
// close the connection
imap_close($inbox,CL_EXPUNGE);
return $result;
}
雖然沒有錯誤出現這樣（的頁面是不從那裏加載函數被調用）控制檯返回這個錯誤：500（內部服務器錯誤）
任何建議，我可能會失蹤？
編輯： 似乎只有當以下的代碼段包括在功能頁面錯誤：
// try to connect
$inbox = imap_open($hostname,$username,$password) or die('Cannot download information: ' . imap_last_error());
// close the connection
imap_close($inbox,CL_EXPUNGE);
建議，我認爲這個問題是端口雖然根據我的EC2安全組正確的端口（993）已打開。有沒有其他的端口應該在這樣的過程中打開？
什麼是錯誤信息？ – nnevala
對不起，我覺得我不夠清楚。沒有錯誤消息，在頁面中使用的函數不會執行任何操作，而是在被調用之後的任何代碼都不會被讀取，因此它最終成爲半載頁面，因爲只有在函數被使用之前的代碼中。 –
控制檯正在收到此錯誤：500（內部服務器錯誤），但只有在調用該函數時。 –
