如何使用PHP / cURL模拟浏览器表单POST方法
我试图使用PHP / cURL来使用POST方法来模拟浏览器。 当我看着那个活的Http头时，它显示了Content-Type: multipart/form-data 。
我在网上查，其中有人提出，卷曲将发送multipart/form-data时候自定义标题被指定为Content-Type: multipart/form-data 。
$headers = array(
'Content-Type' => 'multipart/form-data; boundary='.$boundary
);
当我显示print_r（curl_getinfo（））时，这并不适用于我
[content_type] => text/html; charset=UTF-8
这意味着cURL发送了一个默认标题
我还读到使用cURL发送/上传文件会导致数据作为multipart/form-data 。 我创建了一个curl上传的文件，但是当我运行curl_getinfo我得到了[content_type] => text/html; charset=UTF-8 [content_type] => text/html; charset=UTF-8
$data_array = array("field" => "@c:file_location.txt");
我还尝试读取文件内容，以便发送的唯一内容是内容不附带的文件，但这对我无效curl_getinfo shows [content_type] => text/html; charset=UTF-8 [content_type] => text/html; charset=UTF-8 。
$data_array = array("field" => "<c:file_location.txt"); // note @ replaced with <
我在这里想念什么？

您尚未发布连贯/一致的代码流。 这一点到底是你期望发生的？ 或者是其他东西？
你说“没有工作” -对不起，但我们需要更多的信息，能够帮助您诊断问题。
有没有错误信息？
你想把文件发布到哪里？
接收URL是否与HTTP表单一起使用？
你能提供一个与它一起使用的表单的例子吗？
你是否在接收端控制代码？
你怎么知道它“不起作用”？
你有错误信息吗？ 如果是这样，什么？
操作应该如下简单：
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $THE_REMOTE_URL_YOU_ARE_POSTING_TO);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
"field" => "@c:file_location.txt", // note the double when used within double quotes
'a_number' => 12345.
'a_string' => "hello world"
));
$response = curl_exec($ch);
?>
糟糕的道路可能不是为什么curl_getinfo（）不告诉你你期望看到什么 - 看看实际的数据交换可能会更有帮助。 C。
尝试使用PHP的exec来调用COMMAND LINE VERSION OF CURL ..
对于上传文件，这对我来说是个诀窍。
示例：Webform具有名称为'Filedata'的输入框，用于将文件上传到其服务器上我想上传myImage.jpg
因此，在Linux命令行上（假设在myImage.jpg的文件夹中）
curl -F "Filedata = @myImage.jpg;" 'http://siteyoursubmittingto.php'
如果这个工作，你可以使用类似的东西来调用这个
exec ("curl -F 'Filedata = @myImage.jpg;' 'http://siteyoursubmittingto.php'");
