Linux server configuration https ssl certificate.
2. curl_ request to obtain the content (see the following method curlGet ())

    /**
     * get the content
     * @param $url
     * @return bool|string
     */
    function curlGet($url)
    {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36');

        $content = curl_exec($ch);
        curl_close($ch);
        return ($content);
    }

3.Use file_get_contents() function to skip https authentication

        $streamOpts = [
            'ssl' => [
                'verify_peer' => false,
                'verify_peer_name' => false
            ]
        ];
        $html = file_get_contents($pageUrl, false, stream_context_create($streamOpts));

[Solved] Gerrit Error: Permission denied publickey

Gerrit reports an error: permission denied solution

Foreword solution

Foreword

When using the Gerrit clone code, you will find an error. The error message is probably: permission denied (publickey)

openssh has abandoned RSA encryption keys since version 8.8 for security reasons
openssh thinks that RSA cracking costs too little, so it is disabled if there is a risk
you can use the command:
ssh -v [git server]

Check the openssh version number of the Gerrit server.
if it is ≥ 8.8, you can use this method.

Solution

Enter the machine SSH directory,
create a new config file without suffix:

The content is:

Host gerrit's IP or domain name
HostName gerrit's IP or domain name
User Gerrit's user name (e.g. zhangsan)
PubkeyAcceptedKeyTypes +ssh-rsa
IdentityFile ~/.ssh/id_rsa
Port 29418 (Gerrit port)

Once configured, the clone is OK. Generally, there is no problem.

Resolve the problem of “event ID 4107” or “event ID 11” errors recorded in the application logs of windows and windows server

Problem description
An error similar to the following was logged in the application log on a machine running Windows 7 or Windows Server 2008 R2:
Log name: application

date: date and time
event ID: 4107

Or, an application log on a machine running Windows Vista or Windows Server 2008 records an error similar to the following:
Log name: application

event ID: 11
task category: no

why
The above error occurred because the Microsoft Certificate Trust List publisher certificate has expired. A copy of the CTL whose signature certificate has expired exists in the CryptnetUrlCache folder.
In addition, the event ID 4107 May be logged as a “data invalid” error rather than a “Certificate that is not valid when verified against the current system clock or timestamp in the signature file” error.
