PHP HTTP上下文选项
介绍
下面给出的是 http://和https://传输的上下文选项列表
以下示例从http://URL获取标头和内容
示例
<?php $url = "http://localhost/testscript.php"; $opts = array('http' => array( 'method' => 'GET', 'max_redirects' => '0', 'ignore_errors' => '1' ); $context = stream_context_create($opts); $stream = fopen($url, 'r', false, $context); var_dump(stream_get_meta_data($stream)); ?>
输出结果
这将显示标题信息和元数据,如下所示-
array(10) { ["timed_out"]=> bool(false) ["blocked"]=> bool(true) ["eof"]=> bool(false) ["wrapper_data"]=> array(7) { [0]=> string(15) "HTTP/1.1 200 OK" [1]=> string(35) "Date: Thu, 17 Sep 2020 07:04:47 GMT" [2]=> string(55) "Server: Apache/2.4.41 (Win64) OpenSSL/1.0.2s PHP/7.1.32" [3]=> string(24) "X-Powered-By: PHP/7.1.32" [4]=> string(17) "Content-Length: 0" [5]=> string(17) "Connection: close" [6]=> string(38) "Content-Type: text/html; charset=UTF-8" } ["wrapper_type"]=> string(4) "http" ["stream_type"]=> string(14) "tcp_socket/ssl" ["mode"]=> string(1) "r" ["unread_bytes"]=> int(0) ["seekable"]=> bool(false) ["uri"]=> string(31) "http://localhost/testscript.php" }
