Question

我正在尝试使用PHP / cURL使用POST方法模拟浏览器。当我查看那个直播的Http标题时，它会显示Content-Type: multipart/form-data。

我在互联网上查看了当multipart/form-data指定了自定义标头时，cURL会发送Content-Type: multipart/form-data。

$headers = array(
    'Content-Type' => 'multipart/form-data; boundary='.$boundary
);

当我在print_r（curl_getinfo（））显示

时，这对我不起作用

[content_type] => text/html; charset=UTF-8

这意味着cURL发送了默认标题

我还读到，使用cURL发送/上传文件会导致数据以multipart/form-data的形式发送。我创建了一个卷曲上传的文件但是当我运行时curl_getinfo我得到了[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加文件，但这对我不起作用curl_getinfo显示[content_type] => text/html; charset=UTF-8。

$data_array = array("field" => "<c:\file_location.txt"); // note  @ replaced with <

我想念这里的东西吗？

Answer 1

您尚未发布连贯/一致的代码流。最后的结果是你期望发生的吗？或其他什么？

你说“它不起作用” - 抱歉，但我们需要很多更多信息才能帮助您诊断问题。

是否有错误消息？
您要将文件发布到什么地方？
接收网址是否支持HTTP表单？
您能提供一个与其一起使用的表单示例吗？
您是否在接收端控制代码？
你怎么知道它“不起作用”？
您收到错误消息吗？如果是，那该怎么办？

操作应该如下：

<?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);
?>

糟糕的路径可能会影响为什么curl_getinfo（）没有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。下进行。

Answer 2

尝试使用PHP中的exec来调用CURL的命令行版本。

对于上传文件，这对我有用..

实施例： Webform有一个名为'Filedata'的输入框，用于将文件上传到他们的服务器我想上传myImage.jpg

所以在Linux命令行上，（假设在myImage.jpg）文件夹中

curl -F "Filedata = @myImage.jpg;" 'http://siteyoursubmittingto.php'

如果这样可行，你可以使用像

这样的东西从php调用它

exec ("curl -F 'Filedata = @myImage.jpg;' 'http://siteyoursubmittingto.php'");
