使用PHP连接到Gmail& IMAP [英] Connect to Gmail with PHP & IMAP

问题描述

我从 php.ini OpenSSL 和 IMAP 函数c $ c> file和 phpinfo（）证实它。

通过使用下面的代码，我可以连接到Hotmail帐户，但不是Gmail帐户（当然，我将 $ connect_to 更改为指向Hotmail。）

  $ connect_to ='{imap.gmail.com:993/imap/ssl}INBOX'; 
 $ connection = imap_open（$ connect_to，$ user，$ password）
或die（无法连接到'$ connect_to'：。imap_last_error（））; 
 imap_close（$ connection）; 
  

返回的错误是

 警告：imap_open（）：无法在第6行$ b中的/opt/lampp/htdocs/webmail_client_practise/index.php中打开流{imap.gmail.com:993/imap/ssl}INBOX $ b无法连接到'{imap.gmail.com:993/imap/ssl}INBOX'：imap.gmail.com证书失败：无法获得本地发行者证书：/ C = US / O = GeoTrust Inc. / CN = GeoTrust Global CA 
注意：未知：imap.gmail.com证书失败：无法获得本地签发者证书：/ C = US / O = GeoTrust Inc./CN=GeoTrust Global CA（errflg = 2 ）in Unknown 0 
  

不幸的是，我找不到如何使用IMAP函数的完整教程。

任何想法，解决方案或建议都会有所帮助。 更新：

在Internet上搜索我的问题后，我没有找到完全解决问题的解决方案。虽然如果

<1>我使用不安全的 $ connect_to ='{imap.gmail.com:993/imap/ssl/novalidate-cert} INBOX';

2）允许gmail被较少的安全应用程序访问 ，

I have enabled OpenSSL and IMAP functions from my php.ini file and phpinfo() confirms it.

By using the code below i can connect to a Hotmail account but not to a Gmail account.(of course i change the $connect_to to point to Hotmail.)

$connect_to = '{imap.gmail.com:993/imap/ssl}INBOX';
$connection = imap_open($connect_to, $user, $password)
  or die("Can't connect to '$connect_to': " . imap_last_error());
imap_close($connection);

The returned error is

Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/ssl}INBOX in /opt/lampp/htdocs/webmail_client_practise/index.php on line 6
Can't connect to '{imap.gmail.com:993/imap/ssl}INBOX': Certificate failure for imap.gmail.com: unable to get local issuer certificate: /C=US/O=GeoTrust Inc./CN=GeoTrust Global CA
Notice: Unknown: Certificate failure for imap.gmail.com: unable to get local issuer certificate: /C=US/O=GeoTrust Inc./CN=GeoTrust Global CA (errflg=2) in Unknown on line 0

Unfortunately i cannot find a complete tutorial of how to use the IMAP functions.

Any ideas, solutions or suggestions will be helpful.

解决方案

UPDATE:

After searching for my problem on the Internet, i did not found a solution that solves my problem completely. Although if

1) I use the insecure $connect_to = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';

2)And allow gmail to be accessed by less secured apps,

solves my problem for now.
