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 卷曲代码：

<?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);
}
?>

Answer 1

你的数据字符串有误

dataString = hostName;

那只会包含数据

dataString = {"host":hostName};

那应该在你的 GET 字符串中传递参数 host

Answer 2

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

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

在您的示例中，结果 url 将是

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

注意 "https"
