无法向IMAP服务器进行身份验证:[AUTHENTICATIONFAILED]无效的凭据(失败) 操作系统:debian 7

Can not authenticate to IMAP server: [AUTHENTICATIONFAILED] Invalid credentials (Failure) OS: debian 7

麻烦在哪里?

PHP代码:

<?php   
/* connect to gmail */
$hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
$username = '[e-mail]';
$password = 'pass';

/* try to connect */
$inbox = imap_open($hostname,$username,$password, NULL, 1, array('DISABLE_AUTHENTICATOR' => 'GSSAPI')) or die('Cannot connect to Gmail: ' . imap_last_error());

/* grab emails */
$emails = imap_search($inbox,'ALL');

/* if emails are returned, cycle through each... */
if($emails) {

/* begin output var */
$output = '';

/* 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);
    $message = imap_fetchbody($inbox,$email_number,2);

    /* output the email header information */
    $output.= '<div class="toggler '.($overview[0]->seen ? 'read' : 'unread').'">';
    $output.= '<span class="subject">'.$overview[0]->subject.'</span> ';
    $output.= '<span class="from">'.$overview[0]->from.'</span>';
    $output.= '<span class="date">on '.$overview[0]->date.'</span>';
    $output.= '</div>';

    /* output the email body */
    $output.= '<div class="body">'.$message.'</div>';
}

echo $output;
} 

/* close the connection */
imap_close($inbox);

推荐答案

如果您使用的是G Suite，则必须与G Suite管理员联系，以在Google管理面板中启用对用户应用的不安全访问，URL如https://admin.google.com/{YOUR_DOMAIN_NAME}/AdminHome?hl=en#ServiceSettings/notab=1&service=securitysetting&subtab=lesssecureappsaccess

If you are using G Suite, you have to contact your G Suite administrator to enable not secure access for users apps in Google Admin panel, URL like https://admin.google.com/{YOUR_DOMAIN_NAME}/AdminHome?hl=en#ServiceSettings/notab=1&service=securitysetting&subtab=lesssecureappsaccess

或采用这种方式(对于G Suite管理员)

or go this way (for G Suite admin)

1. https://admin.google.com
2. 安全设置
3. 基本设置(第一个链接)
4. 安全性较低的应用程序->转到安全性较低的应用程序的设置
5. 强制所有用户访问安全性较低的应用程序(不推荐)
6. 保存
7. 利润(可以在1-2分钟内生效，请等待一段时间)

1. https://admin.google.com
2. Security settings
3. Basic settings (first link)
4. Less secure apps -> Go to settings for less secure apps
5. Enforce access to less secure apps for all users (Not Recommended)
6. Save
7. PROFIT (can take effect in 1-2 mins, wait for some time please)
