如何使用php curl将数据发布到ASP站点

Question

我需要张贴数据到ASP网站使用php卷曲从我的网站。

该网站为http://www.hotfrog.com.au/AddYourBusinessSingle.aspx

对于这一点，我如下所示

1. 使用PHP curl从该网站抓取网页html源代码以维护cookie和会话。
2. 从源asp隐藏变量值中提取。
3. 准备好带有所需表单字段的post字符串
4. 并将这些数据发布到使用PHP curl的ASP站点url中，但是响应是页面表单信息，没有条目详细信息，甚至没有显示来自curl响应的非条目字段的验证消息。
5. 对于此过程，CURLOPT_USERAGENT、CURLOPT_COOKIEJAR、CURLOPT_COOKIEFILE保持相同的值。

ASP站点需要的表单字段如下所示

ctl00$contentSection$CompanyDetailsControl$txtBusinessName

ctl00$contentSection$CompanyDetailsControl$txtSuburb

是直接张贴这些字段名，还是在PHP curl发布到目标站点之前需要对这些字段名进行编码？

任何人都可以通过php curl为该解决方案或其他任何ASP站点提供解决方案吗？

使用

function get_headers_from_curl_response($headerContent) {

    $headers = [];

    // Split the string on every "double" new line.
    $arrRequests = explode("\r\n\r\n", $headerContent);

    // Loop of response headers. The "count() -1" is to
    //avoid an empty row for the extra line break before the body of the esponse.
    for ($index = 0; $index < count($arrRequests) - 1; $index++) {

        foreach (explode("\r\n", $arrRequests[$index]) as $i => $line) {
            if ($i === 0) {
                $headers[$index]['http_code'] = $line;
            }
            else {
                list ($key, $value) = explode(': ', $line);
                $headers[$index][$key] = $value;
            }
        }
    }

    return $headers;
}

function regexExtract($text, $regex, $regs, $nthValue) {
    if (preg_match($regex, $text, $regs)) {
        $result = $regs[$nthValue];
    }
    else {
        $result = "";
    }

    return $result;
}

$regexViewstate = '/__VIEWSTATE\" value=\"(.*)\"/i';
$regexEventVal   = '/__EVENTVALIDATION\" value=\"(.*)\"/i';

$ch = curl_init("__YOUR__URL__HERE__");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');

$response = curl_exec($ch);
curl_close($ch);

$viewstate = regexExtract($response, $regexViewstate, $regs, 1);
$eventval  = regexExtract($response, $regexEventVal, $regs, 1);

$params = [
    '__EVENTTARGET'       => '',
    '__EVENTARGUMENT'     => '',
    '__VIEWSTATE'         => $viewstate,
    '__EVENTVALIDATION'   => $eventval,
    'ctl00%24txtUsername' => 'xxx',
    'ctl00%24txtPassword' => 'xxx',
    'ctl00$ImgLogin.x'    => '0',
    'ctl00$ImgLogin.y'    => '0',];

$ch2 = curl_init("http://gsc.klub-modul.dk/cms/ShowContentPage.aspx?ContentPageID=1");
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_HEADER, 1);
curl_setopt($ch2, CURLOPT_POST, true);
curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch2, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch2, CURLOPT_COOKIE, 'cookies.txt');
curl_setopt($ch2, CURLOPT_COOKIEJAR, 'cookies2.txt');

$response2 = curl_exec($ch2);
curl_close($ch2);

foreach (get_headers_from_curl_response($response2) as $value) {
    foreach ($value as $key => $value2) {
        echo $key.": ".$value2."<br />";
    }
}
