Unable to find the socket transport "https"
提问by Chris J Allen
I'm using this to check for the availability of a URL:
我正在使用它来检查 URL 的可用性：
$fp = fsockopen($url, 443, $errno, $errstr);
and I get this error back...
我又得到了这个错误......
Warning: fsockopen() [function.fsockopen]: unable to connect to https://example.com/soapserver.php:443(Unable to find the socket transport "https" - did you forget to enable it when you configured PHP?) in C:\Home etc etc....
警告：fsockopen() [function.fsockopen]：无法连接到https://example.com/soapserver.php:443（无法找到套接字传输“https”-您是否在配置 PHP 时忘记启用它？ ) 在 C:\Home 等....
I'm using an IIS server btw,( no its not my doing! ) so I think its something to do with not having open-ssl, but I'm not sure. Can anyone help please?
顺便说一句，我正在使用 IIS 服务器，（不，这不是我做的！）所以我认为这与没有 open-ssl 有关系，但我不确定。有人可以帮忙吗？
I did a phpinfo() and I do have ssl, but on IMAP and cURL, thats all.
我做了一个 phpinfo() 并且我有 ssl，但是在 IMAP 和 cURL 上，仅此而已。
Any ideas?
有任何想法吗？

also for ssl you need to prefix the host with ssl://
同样对于 ssl，您需要在主机前加上 ssl://

Uncomment the line: extension=php_openssl.dllin php.ini
取消注释该行：extension=php_openssl.dll在php.ini

You should be using just the hostname, not the URL in the fsockopen call. You'll need to provide the uri, minus the host/port in the actual HTTP headers. As @Martijin noted, and as listed in the manual page, you'll need to preface your host name with ssl:// for SSL or tls:// if using transport layer security.
您应该只使用主机名，而不是 fsockopen 调用中的 URL。您需要提供 uri，减去实际 HTTP 标头中的主机/端口。正如@Martijin 指出的那样，并且如手册页中所列，如果使用传输层安全性，您需要在主机名前加上 ssl:// 以表示 SSL 或 tls://。
Manual pagefor fsockopen. Look at Example #1.
fsockopen 的手册页。看示例#1。

Let's say you wanted to grab NY Times, which enforces HTTPS:
假设您想获取强制执行 HTTPS 的纽约时报：
Incorrect:
不正确：
$client = stream_socket_client('https://www.nytimes.com', $errno, $errstr, 30);
$client = stream_socket_client('https://www.nytimes.com', $errno, $errstr, 30);
Correct:
正确的：
$client = stream_socket_client('tcp://www.nytimes.com:443', $errno, $errstr, 30);
$client = stream_socket_client('tcp://www.nytimes.com:443', $errno, $errstr, 30);
Note I've replaced https://with tcp://and appended the 443 port to the hostname.
注意我把它换成https://与tcp://和追加的443端口的主机名。
I guess we can say that stream_socket_client()does not speak URLs.
我想我们可以说不stream_socket_client()说 URL。

Switching to ssl://worked for me but I kept getting a BAD REQUEST response. I found that I needed to add one more line to declare explicitly my Host Header as described hereand ensure that I've updated my HTTP from HTTP/1.0to HTTP/1.1:
切换到ssl://为我工作，但我一直收到 BAD REQUEST 响应。我发现我需要再添加一行来明确声明我的主机头，如here所述，并确保我已将我的 HTTP 更新HTTP/1.0为HTTP/1.1：
$header .= "POST /cgi-bin/webscr HTTP/1.1\r\n";
$header .= "Host: www.sandbox.paypal.com\r\n";

Check curl installed or not for php. if it is not installed install the curl. for windows Uncomment the line: extension=php_openssl.dll in php.ini, for ubuntu sudo apt-get install php-curl
检查 php 是否安装了 curl。如果未安装，请安装 curl。对于 windows 取消注释行：extension=php_openssl.dll in php.ini，对于 ubuntu sudo apt-get install php-curl
