使用cURL发送文件 [英] Sending File with cURL

问题描述

我使用cURL发送了一些帖子数据，现在正在尝试发送一个文件，在途中丢​​失。我使用一个带有文件输入的窗体。然后想要cURL将其发送到我的服务器。这是我的上传页面。
< form action =curl_page.phpmethod =postenctype =multipart / form-data>
文件名：< input type =filename =fileid =file/> < br />
< input type =submitname =submitvalue =Submit/>
< / form>

这是我的curl页面有一些问题。

 <？php 
 $ tmpfile = $ _FILES ['file'] ['tmp_name']; 
 $ filename = basename（$ _ FILES ['file'] ['name']）; 
 
 $ ch = curl_init（）; 
 curl_setopt（$ ch，CURLOPT_URL，http：//my_server/file_catch.php）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，1）; 
 curl_setopt（$ ch，CURLOPT_POST，true）; 
 $ data = array（
'uploaded_file'=>'@'。$ tmpfile。'; filename ='。$ filename，
）; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ data）; 
 $ output = curl_exec（$ ch）; 
 curl_close（$ ch）; 
？> 
  

我的服务器上的file_catch.php看起来像这样。

 <？php 
 $ folder =audio /; 
 
 $ path = $ folder。 basename（$ _FILES ['file'] ['name']）; 
 
 if（move_uploaded_file（$ _ FILES ['file'] ['tmp_name']，$ path））{
 echo文件。 basename（$ _FILES ['file'] ['name']）。 已上传; 
} else {
 echo上传文件时出错，请重试！ 
} 
？>感谢任何帮助！
解决方案
您不是发送通过发布请求获得的文件。使用以下代码通过CURL请求发布文件。
  $ tmpfile = $ _FILES ['image'] ['tmp_name' ]; 
 $ filename = basename（$ _ FILES ['image'] ['name']）; 
 
 $ data = array（
'uploaded_file'=>'@'。$ tmpfile。'; filename ='。$ filename，
）; 
 
 $ ch = curl_init（）; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ data）; 
 //在这里设置你的其他cURL选项（url等）
 
 curl_exec（$ ch）;

 通过cURL通过PHP在表单POST中发送文件 
 
I've sent some post data with cURL and am now trying to send a file, getting lost along the way. I'm using a form with a file input. Then would like cURL to send it off to my server. Here is my upload page.
    <form action="curl_page.php" method="post" enctype="multipart/form-data">
    Filename: <input type="file" name="file" id="file" /> <br />
    <input type="submit" name="submit" value="Submit" />
    </form>

Here is my curl page with some issues.
<?php
$tmpfile = $_FILES['file']['tmp_name'];
$filename = basename($_FILES['file']['name']);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://my_server/file_catch.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
$data = array(
    'uploaded_file' => '@'.$tmpfile.';filename='.$filename,
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$output = curl_exec($ch);
curl_close($ch);
?>
The file_catch.php on my server looks like this.
<?php
$folder = "audio/";

$path = $folder . basename( $_FILES['file']['name']);

if(move_uploaded_file($_FILES['file']['tmp_name'], $path)) {
    echo "The file ".  basename( $_FILES['file']['name']). " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}
?>
Thanks for any help!
解决方案
You are not sending the file that you got through the post request. Use the below code for posting the file through CURL request.
$tmpfile = $_FILES['image']['tmp_name'];
$filename = basename($_FILES['image']['name']);

$data = array(
    'uploaded_file' => '@'.$tmpfile.';filename='.$filename,
);

$ch = curl_init();   
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
// set your other cURL options here (url, etc.)

curl_exec($ch);
