在cURL PHP中启用https的SSL连接(标题空白)

Question

我正在写一个cURL脚本来访问Fannie Mae网站的当前天利率,即https.我还没能通过CURLOPT_SSL_VERIFYPEER,真的); 选项.

无需用户名或密码,但我需要启用SSL验证.

在XAMPP开发服务器上测试.

我已经使用FF从网站上下载了.crt和.pem证书并将它们保存在同一个源目录中并使用CURLOPT_CAINFO指向两者,没有运气

我从http://curl.haxx.se/ca/cacert.pem下载了最新的cacert.pem文件,并指出使用CURLOPT_CAINFO,没有运气.

如果我将CURLOPT_SSL_VERIFYPEER转为false,我可以检索标题(见下文),但是当我将其设置为true时,没有标题.

尝试通过在这里搜索找到的7-8个解决方案,同时阅读cURL上的php文档并尝试列出其中的几个解决方法,没有运气.

我需要能够使用CURLOPT_SSL_VERIFYPEER,true检索标题并最终检索正文

任何帮助表示赞赏.

//turn error reporting on

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); // 10s timeout time for cURL connection
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // allow https verification if true
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); // check common name and verify with host name
curl_setopt($ch, CURLOPT_SSLVERSION,3); // verify ssl version 2 or 3
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "VeriSignClass3PublicPrimaryCertificationAuthority-G5.pem"); // allow ssl cert direct comparison
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header'); // get header
curl_setopt($ch, CURLOPT_NOBODY, true); // exclude body
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE); // set new cookie session
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); // file to save cookies in
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); // file to read cookies in

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL connection, save cookie file, free up system resources
curl_close($ch);

// show header
function read_header($ch, $string) {
    print "Received header: $string";
    return strlen($string);
}
?>

如果CURLOPT_SSL_VERIFYPEER设置为false,则为接收的标头,如果为true,则为空

你是通过使用排除身体curl_setopt($ch, CURLOPT_NOBODY, true);.我认为您不需要在您的计算机上安装证书.以下几行将为您提供一切.

$url = 'https://www.fanniemae.com/content/datagrid/hist_net_yields/cur30.html';
$ch = curl_init();    
curl_setopt($ch, CURLOPT_URL, $url); // set url
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); // set browser/user agent    
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header'); // get header
curl_exec($ch);

function read_header($ch, $string) {
    print "Received header: $string";
    return strlen($string);
}
