如何使用PHP / cURL模拟浏览器表单POST方法

提问于

我正在尝试使用PHP / cURL使用 POST 方法模拟浏览器 . 当我看着那个直播的Http Headers 时,它显示了 Content-Type: multipart/form-data .

我在互联网上检查了当为 Content-Type: multipart/form-data 指定自定义标头时,cURL将发送 multipart/form-data .

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

当我显示print_r(curl_getinfo())时,这对我不起作用

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

这意味着cURL发送了默认标头

我还读到使用cURL发送/上传文件将导致数据作为 multipart/form-data 发送 . 我创建了一个curl上传的文件但是当我运行 curl_getinfo 时我得到 [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?

    您没有发布一致的/一致的代码流 . 最后的结果是你期望发生的吗?或者是其他东西?

    你说"it didn't work" - 对不起,但是我们需要更多的信息来帮助你诊断问题 .

    • 有错误信息吗?

    • 您要将文件发布到什么内容?

    • 接收URL是否与HTTP表单一起使用?

    • 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?如果是这样,什么?

    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 - 看实际的数据交换可能会更有帮助 . C .

    尝试使用PHP中的 exec 来调用COMMAND LINE VERSION OF CURL ..

    对于上传文件,这对我有用 .

    示例: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要上传 myImage.jpg

    所以在Linux命令行上,(假设在 myImage.jpg 的文件夹中)

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

    如果这样可行,你可以使用类似的东西从php调用它

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