如何从 curl 请求提交远程文件作为表单数据 - how to submit remote file from curl request as form data

how to submit remote file from curl request as form data

我的PHP应用程序设置为用户可以通过表单保存/上传文件。我正在尝试编写一个 shell 脚本（由 cron 作业运行），该脚本重用相同的模型方法，但用于未通过表单提交的文件。我目前正在使用 curl 来获取文件，但我对其他解决方案持开放态度。

以下是我目前获取文件的方式：

$ch = curl_init($image_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$photo_data = curl_exec($ch);
curl_close($ch);

这似乎返回了 base64 编码的数据...

...

这是我的应用程序期望的帖子数据的格式：

[Photo] => Array
    (
        [file] => Array
            (
                [name] => desert2.jpg
                [type] => image/jpeg
                [tmp_name] => /Applications/MAMP/tmp/php/php65uUCk
                [error] => 0
                [size] => 96573
            )
    )

所以我的问题是，如何使通常处理上述 post 请求数据的脚本可以访问 curl ed 文件数据？

<?php
// cURL
$ch = curl_init($image_url); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
$photo_data = curl_exec($ch); 
curl_close($ch); 
// Create Image Array
$imageData = array(
                "name"=>"IMAGE NAME",
                "type"=>"image/jpeg",
                "tmp_name"=>"TEMP NAME",
                "error"=>0,
                "size"=>str_len($photo_data),
                "photo"=>$imageData // Add this line as there is nothing in the data structure given that will pass the image data
             );
// URL
$url = parse_url("http://www.wherethisisgoing.com/page.php");
$host = $url["host"];
$path = $url["path"];
$httpData = http_build_query($imageData); // Converts array to URL Parameters
$socket = fopensock($host, 80, $errno, $error, 30); // 80 is the port and 30 is the timeout length
if($socket) {
    fputs($socket, "POST " . $path . " HTTP/1.1'r'n");
    fputs($socket, "Host: " . $host . "'r'n");
    fputs($socket, "Referrer: PUT SENDING URL HERE'r'n");
    fputs($socket, "Content-type: application/x-www-form-urlencoded'r'n");
    fputs($socket, "Content-length " . strlen($imageData) . "'r'n");
    fputs($socket, "Connection: close'r'n'r'n");
    fputs($socket, $imageData);
    while(feof($socket)) {
        // Get Results
        $result .= fgets($socket, 128); // 128 should be enough to receive the response from the script
    }
} else {
    return array(
                    "status"=>"error",
                    "error"=>$error . " (" . $errno . ")" 
                );
}
//Do some type of checking to verify the image was uploaded
fclose($socket);
