如何上传文件使用curl与php [英] how to upload file using curl with php

问题描述

我想知道如何使用cURL或PHP中的任何其他内容上传文件。我已经在Google中搜索了很多次但没有结果。

I want to know how to upload file using cURL or anything else in PHP. I have searched in google many times but no results.

我有这个代码接收文件并上传

I have this code to receive the file and upload it

code：

echo"".$_FILES['userfile']."";
$uploaddir = './';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
if ( isset($_FILES["userfile"]) ) {
    echo '<p><font color="#00FF00" size="7">Uploaded</font></p>';
    if (move_uploaded_file
($_FILES["userfile"]["tmp_name"], $uploadfile))
echo $uploadfile;
    else echo '<p><font color="#FF0000" size="7">Failed</font></p>';
}

我希望代码将文件发送到接收器文件。

I want the code to send the file to receiver file.

推荐答案

使用：

if (function_exists('curl_file_create')) { // php 5.6+
  $cFile = curl_file_create($file_name_with_full_path);
} else { // 
  $cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

PHP 5.5 +的重要提示：

Important hint for PHP 5.5+:

现在我们应该使用 https://wiki.php.net/rfc/curl-file-upload ，但如果您仍想使用此已弃用的方法，则需要设置 curl_setopt（$ ch，CURLOPT_SAFE_UPLOAD，false）;

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
