通过使用PHP通过IMAP连接到Gmail - SSL上下文失败

Question

我试图通过IMAP与运行在Apache中的PHP连接到Gmail。这是在Ubuntu 9.04系统上。我有一些PHP配置问题，使这从工作。首先，这里就是我所做的设置IMAP的PHP：

sudo apt-get install libc-client2007b libc-client2007b-dev 
sudo apt-get install php5-imap 
sudo /etc/init.d/apache2 start 

当我运行phpinfo（）函数，我得到以下的imap值：

IMAP c-Client Version: 2004 
SSL Support: enabled 
Kerberos Support: enabled 

这里是我的示例代码：

<?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); 
?> 

当我执行此代码时，我得到以下输出：

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telnet到imap.gmail.com:993。我还可以通过IMAP将Evolution（邮件阅读器）连接到Gmail，并在没有问题的情况下获取邮件。所以，我不认为这是一个防火墙问题。我很确定我有一些PHP没有正确设置。

任何想法？

Answer 1

您需要在PHP中启用的另一项功能是OpenSSL extension。看起来，IMAP客户端库（使用SSL）依赖于此。

如果Apache启用了OpenSSL模块，因为在将请求交给PHP之前处理/处理，这并不重要。

下面的话题可能会帮助一些启发：

Answer 2

检查您的设置与phpinfo()并确保您看到--with-imap-ssl列出。

Answer 3

在命令行中运行你的代码，看看PHP的吐出了其它的错误：

php -f gmail.php 

在我的Ubuntu我所做的：

sudo apt-get install php5-imap 

而且系统安装功能：libc-client2007b m锁libc-client2007b mlock php5-imap

那么如何卸载php5并重新安装干净。

这已经经过长期努力，为我工作：

$ServerName = "{imap.gmail.com:993/imap/ssl/novalidate-cert/norsh}Inbox"; 

Answer 5

如果你仍然有这个问题上gmail，请确保在您的Google帐户安全设置页面中启用“允许访问安全性较低的应用”。

Answer 6

与Google应用上的个人域名有相同的问题。通过更改应用程序对帐户的访问来解决问题。只需按照by link并开启对账户的访问。

Answer 7

我正面临同样的问题。 我使用的是windows和wamp，我的wamp“openSSl”扩展已启用。

我通过使用以下步骤删除了此问题。我希望这也适用于您。

1）通过浏览器登录到Gmail帐户。

2）打开这个网址 “https://www.google.com/settings/security/lesssecureapps”

3）单击 “打开”

4）尝试下面的代码

<?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

    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); 


?> 

好运。 :)

1. 首先，在您的Gmail帐户启用安全性较低的应用程序：https://myaccount.google.com/lesssecureapps

2. 使用该配置来创建IMAP连接：

   $imap_connection = imap_open('{imap.gmail.com:993/imap/ssl/novalidate- 
   cert}INBOX', 'YOUR GMAIL USER', 'YOUR GMAIL PASSWORD'); 
   

注意：收件箱是您的主要imbox，例如，您可以访问发送的项目：INBOX.Sent连接。
