How to enable HTTPS stream wrappers
提问by Tamppox
I installed php5 on my windows system and tried to execute the following script with a command-line console:
我在 Windows 系统上安装了 php5，并尝试使用命令行控制台执行以下脚本：
<?php
// load in credentials
$creds = parse_ini_file('/etc/aws.conf');
// Define query string keys/values
$params = array(
'Action' => 'DescribeAvailabilityZones',
'AWSAccessKeyId' => $creds['access_key'],
'Timestamp' => gmdate('Y-m-d\TH:i:s\Z'),
'Version' => '2008-05-05',
'ZoneName.0' => 'us-east-1a',
'ZoneName.1' => 'us-east-1b',
'ZoneName.2' => 'us-east-1c',
'SignatureVersion' => 2,
'SignatureMethod' => 'HmacSHA256'
);
// See docs
// http://tr.im/jbjd
uksort($params, 'strnatcmp');
$qstr = '';
foreach ($params as $key => $val) {
$qstr .= "&{$key}=".rawurlencode($val);
}
$qstr = substr($qstr, 1);
// Signature Version 2
$str = "GET\n"
. "ec2.amazonaws.com\n"
. "/\n"
. $qstr;
// Generate base64-encoded RFC 2104-compliant HMAC-SHA256
// signature with Secret Key using PHP 5's native
// hash_hmac function.
$params['Signature'] = base64_encode(
hash_hmac('sha256', $str, $creds['secret_key'], true)
);
// simple GET request to EC2 Query API with regular URL
// encoded query string
$req = 'https://ec2.amazonaws.com/?' . http_build_query(
$params
);
$result = file_get_contents($req);
// do something with the XML response
echo $result;
But it says that it's unable to find the wrapper "https" and asks if I forget to enable it when I configured PHP.
但是它说它找不到包装器“https”，并询问我在配置 PHP 时是否忘记启用它。
What is the problem and how to settle it?
问题是什么以及如何解决？

1: Check which wrappers are installed.
1：检查安装了哪些包装器。
<?php var_dump(stream_get_wrappers()); ?>
2: If you dont see "https" on the list, add to/uncomment from php.ini
2：如果在列表中没有看到“https”，请在php.ini中添加/取消注释
extension=php_openssl.dll
Restart your server*, and your done.
重启你的服务器*，大功告成。
*if server fails to restart go download php_openssl.dll from someplace and stick it in your extensions directory defined in the php.ini file, restart server, say a few hell mary's and pray.
*如果服务器无法重新启动，请从某个地方下载 php_openssl.dll 并将其粘贴到 php.ini 文件中定义的扩展目录中，重新启动服务器，说几句地狱玛丽并祈祷。

The file_get_contentsline, at the end of your script, is trying to send an HTTPS request -- see the URL in $req, which starts by 'https://ec2...'.
file_get_contents脚本末尾的这一行正在尝试发送 HTTPS 请求 - 请参阅 中的 URL $req，该URL 以开头'https://ec2...'。
For this to be possible, PHP needs a "wrapper" to send HTTPS requests -- which doesn't seem to be installed on your system ; which means you cannot send HTTPS requests using the fopenfamilly of functions.
为此，PHP 需要一个“包装器”来发送 HTTPS 请求——您的系统上似乎没有安装它；这意味着您不能使用fopen函数家族发送 HTTPS 请求。
For more informations about stream wrappers, if you are curious, you can take a look at List of Supported Protocols/Wrappers, and, in your case, HTTP and HTTPS.
有关流包装器的更多信息，如果您感到好奇，可以查看List of Supported Protocols/Wrappers，以及在您的情况下，HTTP 和 HTTPS。
You'll either have to install the HTTPs wrapper -- on Windows, I have no idea how to do that, unfortunately...
你要么必须安装 HTTPS 包装器——在 Windows 上，我不知道如何做到这一点，不幸的是......
Or you'll have to use something else that file_get_contentsto send your HTTPS request -- I would use the functions provided by the curlextension (Here, too, not sure it will work "out of the box", though :-( ).
或者你必须使用其他东西file_get_contents来发送你的 HTTPS 请求——我会使用curl扩展提供的功能（在这里，也不确定它是否可以“开箱即用”，但 :-( )。
For an example, you can take a look at what's proposed on the manual page of curl_exec:
例如，您可以查看以下手册页上的建议curl_exec：
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
Note you'll probably have to set a couple more options, using curl_setopt-- you should go through that page : there are a lot of useful options ;-)
请注意，您可能需要设置更多选项，使用curl_setopt- 您应该浏览该页面：有很多有用的选项;-)
As a sidenote, you are using this line at the beginning of your script :
作为旁注，您在脚本的开头使用了这一行：
$creds = parse_ini_file('/etc/aws.conf');
The path /etc/aws.conffeels strange, as you said you are using a Windows system : this looks like the kind of path one would use on an UNIX/Linux system.
这条路径/etc/aws.conf感觉很奇怪，正如您所说，您使用的是 Windows 系统：这看起来像是在 UNIX/Linux 系统上使用的那种路径。

Open php.ini. Find this line:
打开php.ini。找到这一行：
;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;
; ...
;extension=ext/php_oci8.dll
extension=ext/php_openssl.dll ; <---- you want this
;extension=ext/php_pdo_firebird.dll
; ...
you want to uncomment the extension=ext/php_openssl.dllline. Make sure there is a pho_openssl.dllfile in the ext/directory, relative to your php.ini(or maybe more importantly to the extension_dirvariable in the ini).
您想取消注释该extension=ext/php_openssl.dll行。确保目录中有一个pho_openssl.dll文件ext/，相对于您的php.ini（或者更重要的extension_dir是相对于 ini 中的变量）。

Simple. I had this error and gave me such headaches. Enable (uncomment the line extension=php_openssl.dll) in your php.ini file. This will solve the issue.
简单的。我有这个错误，让我很头疼。extension=php_openssl.dll在 php.ini 文件中启用（取消注释该行）。这将解决问题。
