fsockopen https 在 fgets 上冻结
我尝试通过 PHP fsockopen 连接到服务器，最初获取用于基本身份验证的 cookie，然后持久连接到响应的 Location 标头中定义的流服务器。
问题是我的代码在 fgets 上冻结并且从未从目标服务器接收到任何响应数据。我通过 Amazon ec2 实例上的端口 443 上的 https 进行连接。服务器通过我的服务器终端中的curl或通过我的chome浏览器连接良好。
$this->conn = fsockopen('ssl://[destination_server]', 443, $errNo, $errStr, $this->connectTimeout);
stream_set_blocking($this->conn, 1);
fwrite($this->conn, "GET " . $urlParts['path'] . " HTTP/1.0\r\n");
fwrite($this->conn, "Host: " . $urlParts['host'] . "\r\n");
fwrite($this->conn, "Content-type: application/x-www-form-urlencoded\r\n");
fwrite($this->conn, "Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
fwrite($this->conn, 'Authorization: Basic ' . $authCredentials . "\r\n");
fwrite($this->conn, 'User-Agent: ' . self::USER_AGENT . "\r\n");
list($httpVer, $httpCode, $httpMessage) = preg_split('/\s+/', trim(fgets($this->conn, 1024)), 3);
//code never gets here!!!
有什么想法吗？
I attempting to connect to a server via PHP fsockopen to initially get a cookie for basic auth and then to persistently connect to a streaming server defined in the Location header of the response.
The problem is that my code freezes on fgets and never receives any response data from the destination server. I'm connecting via https on port 443 on an Amazon ec2 instance. The server connects fine via curl in my server's terminal or via my chome browser.
$this->conn = fsockopen('ssl://[destination_server]', 443, $errNo, $errStr, $this->connectTimeout);
stream_set_blocking($this->conn, 1);
fwrite($this->conn, "GET " . $urlParts['path'] . " HTTP/1.0\r\n");
fwrite($this->conn, "Host: " . $urlParts['host'] . "\r\n");
fwrite($this->conn, "Content-type: application/x-www-form-urlencoded\r\n");
fwrite($this->conn, "Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
fwrite($this->conn, 'Authorization: Basic ' . $authCredentials . "\r\n");
fwrite($this->conn, 'User-Agent: ' . self::USER_AGENT . "\r\n");
list($httpVer, $httpCode, $httpMessage) = preg_split('/\s+/', trim(fgets($this->conn, 1024)), 3);

我通过添加标题解决了这个问题：“连接：关闭\r\n\r\n”。
对 cookie 的初始请求将返回 302 重定向代码，并将位于打开的连接上，除非您传递该标头。
不幸的是，这句话让我难住了一段时间。
I solved this problem by adding the header: "Connection: Close\r\n\r\n".
The initial request for the cookie returns a 302 redirect code and will sit on the open connection unless you pass that header.
Unfortunately, this little line had me stumped for a while.
