PHP curl提交空负载

Question

我试图使用PHP curl提交一个有效负载与一些文件。下面是我的submit.php

<?php

$url = "http://example.com/receive.php";

$payload = array();
$payload['resource_name'] = 'hello world';
$payload['resource_file'] = curl_file_create("test-pdf.pdf");

$headr = array();
//$headr[] = 'Content-Type: multipart/form-data';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headr);
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($payload));

// Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

curl_close ($ch);
print_r($response);
echo "\n";

<?php
print_r($_REQUEST);
print_r($_FILES);

Array
(
    [resource_name] => hello world
    [resource_file] => Array
        (
            [name] => test-pdf.pdf
            [mime] =>
            [postname] =>
        )

)
Array
(
)

为什么我的$_files数组是空的？

如果启用multipart/form-data行，那么$_request和$_files都为空。我做错了什么？如何在receive.php中同时填充$_request和$_files数组？

删除http_build_query并解决问题。

curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);

原因是http_build_query将为x-www-form-urlencoded生成URL编码的查询字符串
