Question

我试图通过PHP CURL发布表单。这是我使用的代码:(已编辑）

// This is some data in the $postfields, cut of version because there is a lot of fields

$postdata = array(
// Fields with a name starting with '_D:/' are hidden and set to one space char
'_dyncharset' => 'UTF-8', '_dynSessConf' => '-7211106995117675809', '/claims/BrgClaimFormhandler.value.firstName' => 'John', 
'_D:/claims/BrgClaimFormhandler.value.firstName' => ' ', '/claims/BrgClaimFormhandler.value.email' => 'johndoe@example.com',
'_D:/claims/BrgClaimFormhandler.value.email' => ' ', '/claims/BrgClaimFormhandler.value.telephone' => '555 783 4574', 
'_D:/claims/BrgClaimFormhandler.value.telephone' => ' ' // ....
);
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://www.hyatt.com/hyatt/specials/offers/brgClaimPage.jsp");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Allow for redirects.
curl_setopt($ch, CURLOPT_TIMEOUT, 500); // Set the curl functions timeout.
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); // Set the connect timeout to wait indefinitely.
curl_setopt($ch, CURLOPT_USERAGENT, "Opera/9.80 (Windows NT 5.1) Presto/2.12.388 Version/12.15");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Suspend output.
curl_setopt($ch, CURLOPT_COOKIEJAR, 'C:\tmp\hyatt_cookies.txt'); // Save cookies to this file.


curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/webp, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1',
'Accept-Language: hr-BA,hr;q=0.9,en;q=0.8', 'Accept-Encoding: utf-8', 'Connection: Keep-Alive',
));

$j = curl_exec($ch); // Execute the curl command.

curl_close($ch);
unset($ch);

// Second request:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Allow for redirects.
curl_setopt($ch, CURLOPT_TIMEOUT, 500); // Set the curl functions timeout.
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); // Set the connect timeout to wait indefinitely.
curl_setopt($ch, CURLOPT_USERAGENT, "Opera/9.80 (Windows NT 5.1) Presto/2.12.388 Version/12.15");
curl_setopt($ch, CURLOPT_COOKIEFILE, 'C:\tmp\hyatt_cookies.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Suspend output.
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postdata));

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/webp, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1',
'Accept-Language: hr-BA,hr;q=0.9,en;q=0.8', 'Accept-Encoding: utf-8', 'Connection: Keep-Alive',
'Content-Type: multipart/form-data; boundary=----------dLk3HzGmthYEYQtSHNptND; charset=UTF-8'));

$h = curl_exec($ch);

curl_close($ch);

echo $h;

页面显示在输出中，但仅在首次访问页面时没有成功发布，没有关于无效或缺少字段的消息。

当我手动发布这些数据时，我获得了成功，当我故意省略一些数据时，我会收到有关所需字段缺失消息的表单。

但是，当我通过此代码执行此操作时，我只是显示带有表单的页面以输入数据而没有消息丢失或无效。

我还可以使用curl_opt（）或其他一些技术来设置其他技术吗？

最有可能的问题是该网站会检查Cookie。这个过程主要包括两个阶段：

当您访问表单页面服务器时设置一些cookie
当您发布表单数据服务器检查该cookie

因此，您必须在脚本中重现此过程，并启用Cookie自动处理（通过CURLOPT_COOKIEFILE / CURLOPT_COOKIEJAR选项）。这意味着你必须做两个卷曲请求：

获取表单页面
发布表单数据

BTW，curl_getinfo()应在 curl_exec致电后被称为。
