php curl 检查 ssl 连接

Question

我的 php curl 连接需要一些帮助 - 在我的 firebug 控制台中，我不断收到此错误

Notice: Undefined index: host in C:\xampp\htdocs\labs\test2\get.php on line 6
Error:3 malformed

AJAX代码:

    var hostName = $("input#host").val();
dataString = hostName;

$.ajax({
    type: "GET",
    url: "get.php",
    data: dataString,
    dataType: "json",

PHP CURL 代码:

<?php
if($fp = tmpfile())
{
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $_GET['host']);
    curl_setopt($ch, CURLOPT_STDERR, $fp);
    curl_setopt($ch, CURLOPT_CERTINFO, 1);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);
    $result = curl_exec($ch);
    curl_errno($ch)==0 or die("Error:".curl_errno($ch)." ".curl_error($ch));
    fseek($fp, 0);//rewind
    $str='';
    while(strlen($str.=fread($fp,8192))==8192);
    echo $str;
    fclose($fp);
}
?>

http_build_query 不会创建有效的 url，只会为您的 GET 请求格式化参数数组。 你应该做类似的事情:

$url = "https://".$_REQUEST['host']."?"."{$query_string}";

在您的示例中，生成的 url 将是

https://www.google.com?host=www.google.com

注意“https”
