问题描述
我正在尝试通过Apache中运行的PHP通过IMAP连接到Gmail。这是在Ubuntu 9.04系统上。我遇到了某种PHP配置问题，无法解决此问题。首先，这是我为PHP设置IMAP的工作：
sudo apt-get install libc-client2007b libc-client2007b-dev
sudo apt-get install php5-imap
sudo /etc/init.d/apache2 start
运行 phpinfo()时，得到以下imap值：
IMAP c-Client Version: 2004
SSL Support: enabled
Kerberos Support: enabled
这是我的示例代码：
<?php
$connect_to = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$user = 'my gmail address';
$password = 'my gmail password';
$connection = imap_open($connect_to, $user, $password)
or die("Can't connect to '$connect_to': " . imap_last_error());
imap_close($connection);
?>
执行此代码时，将得到以下输出：
Warning: imap_open() [function.imap-open]: Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX in /var/www/clint/gmail/gmail.php on line 10
Can't connect to '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX': TLS/SSL failure for imap.gmail.com: SSL context failed
请注意，我可以从这台计算机远程登录到imap.gmail.com:993。我还可以通过IMAP将Evolution(邮件阅读器)连接到Gmail，并毫无问题地获取邮件。因此，我认为这不是防火墙问题。我很确定我在PHP中有一些设置不正确的东西。
有任何想法吗？
最佳办法
需要在PHP中启用的另一项功能是OpenSSL extension。似乎IMAP客户端库(带有SSL)取决于此。
Apache是否启用了OpenSSL模块并不重要，因为在将请求移交给PHP之前已对其进行了处理/处理。
以下讨论线程可能有助于阐明一些观点：
次佳办法
经过长时间的努力，这对我有用：
$ServerName = "{imap.gmail.com:993/imap/ssl/novalidate-cert/norsh}Inbox";
第三种办法
我面临着同样的问题。我正在使用Windows和Wamp，并且我的Wamp “openSSl”扩展已启用。
我通过以下步骤解决了这个问题。希望这对您也有用。
1)通过浏览器登录到Gmail帐户。
2)打开此网址“ https://www.google.com/settings/security/lesssecureapps”
3)点击”turn on”
4)尝试以下代码
<?php
set_time_limit(4000);
// Connect to gmail
//$imapPath = '{imap.gmail.com:993/imap/ssl}INBOX';
$imapPath = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$username = 'your-emai-address@gmail.com';
$password = 'Your-password';
// try to connect
$inbox = imap_open($imapPath,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error());
/* ALL - return all messages matching the rest of the criteria
ANSWERED - match messages with the \\ANSWERED flag set
BCC "string" - match messages with "string" in the Bcc: field

CC "string" - match messages with "string" in the Cc: field
DELETED - match deleted messages
FLAGGED - match messages with the \\FLAGGED (sometimes referred to as Important or Urgent) flag set
FROM "string" - match messages with "string" in the From: field
KEYWORD "string" - match messages with "string" as a keyword
NEW - match new messages
OLD - match old messages
ON "date" - match messages with Date: matching "date"
RECENT - match messages with the \\RECENT flag set
SEEN - match messages that have been read (the \\SEEN flag is set)
SINCE "date" - match messages with Date: after "date"
SUBJECT "string" - match messages with "string" in the Subject:
TEXT "string" - match messages with text "string"
TO "string" - match messages with "string" in the To:
UNANSWERED - match messages that have not been answered
UNDELETED - match messages that are not deleted
UNFLAGGED - match messages that are not flagged
UNKEYWORD "string" - match messages that do not have the keyword "string"
UNSEEN - match messages which have not been read yet*/
// search and get unseen emails, function will return email ids
$emails = imap_search($inbox,'UNSEEN');
$output = '';
foreach($emails as $mail) {
$headerInfo = imap_headerinfo($inbox,$mail);
$output .= $headerInfo->subject.'<br/>';
$output .= $headerInfo->toaddress.'<br/>';
$output .= $headerInfo->date.'<br/>';
$output .= $headerInfo->fromaddress.'<br/>';
$output .= $headerInfo->reply_toaddress.'<br/>';
$emailStructure = imap_fetchstructure($inbox,$mail);
//var_dump($emailStructure->parts);
if(isset($emailStructure->parts)) {
$output .= imap_body($inbox, $mail, FT_PEEK);
} else {
//
}
echo $output;
$output = '';
}
// colse the connection
imap_expunge($inbox);
imap_close($inbox);
?>
祝你好运。 🙂
第四种办法
在Google Apps上的个人域也有同样的问题。通过将应用程序访问权限更改为帐户可以解决问题。只需遵循by link并打开对帐户的访问即可。
