php – 使用fsockopen上传多个文件并发布变量

2019年8月4日 200次阅读

我想要使​​用fsockopen在http请求中发送多个文件并发布变量.

已经拿出这个代码,但我不知道如何发送文件的post vars！？已经取消注释了构建post数据查询的行,但是不知道如何将它放在请求中！？ 🙁

的index.php

$post_vars = [
    'label' => 'description of the upload'
];

$files = [
    'upload_file_1.txt',
    'upload_file_2.txt'
];

try{
    $boundary = sha1(1);
    $crlf = "\r\n";
    $body = '';

    foreach($files as $file){
        $finfo = new \finfo(FILEINFO_MIME);
        $mimetype = $finfo->file($file);

        $file_contents = quoted_printable_encode(file_get_contents($file));

        $body .= '--'.$boundary.$crlf
            .'Content-Disposition: form-data; name="files[]"; filename="'.basename($file).'"'.$crlf
            .'Content-Type: '.$mimetype.$crlf
            .'Content-Length: '.strlen($file_contents).$crlf
            .'Content-Type: application/octet-stream'.$crlf.$crlf
            .$file_contents.$crlf;
    }

    $body .= '--'.$boundary.'--';

    //$post_data = http_build_query($post_vars);

    $response = '';
    if($fp = fsockopen('localhost', 80, $errno, $errstr, 20)){
        $write = "POST /api_test/filepost/post.php HTTP/1.1\r\n"
            ."Host: localhost\r\n"
            ."Content-type: multipart/form-data; boundary=".$boundary."\r\n"
            ."Content-Length: ".strlen($body)."\r\n"
            ."Connection: Close\r\n\r\n"
            .$body;
        fwrite($fp, $write);

        echo "-------------------- REQUEST START --------------------\n".$write."\n-------------------- REQUEST END --------------------\n\n\n";

        while($line = fgets($fp)){
            if($line !== false){
                $response .= $line;
            }
        }

        fclose($fp);

        echo "-------------------- RESPONSE START --------------------\n".$response."\n-------------------- RESPONSE END --------------------\n\n";
    }
    else{
        throw new Exception("$errstr ($errno)");
    }
}
catch(Exception $e){
    echo 'Error: '.$e->getMessage();
}

post.php中

echo "get\n";
print_r($_GET);

echo "post\n";
print_r($_POST);

echo "files\n";
print_r($_FILES);
