谁能给我一个PHP的CURLFile类的例子?

标签: php curl upload

我有一个非常简单的PHP代码来将文件上传到远程服务器;我这样做的方式(正如其他一些解决方案中所建议的那样)是使用cUrl上传文件。

这是我的代码:

$ch = curl_init("http://www.remotesite.com/upload.php"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('fileupload' => '@'.$_FILES['Filedata']['tmp_name'])); 
echo curl_exec($ch);        

服务器正在运行PHP 5.5.0,并且CURLOPT_POSTFIELDS描述中here所述的PHP> = 5.5.0已弃用@filename,因此,我是收到此错误:

Deprecated: curl_setopt(): The usage of the @filename API for file uploading is deprecated. Please use the CURLFile class instead in ... 

有趣的是,除了基本的类概述之外,php.net上的这个类绝对没有。没有示例,没有方法或属性的描述。它基本上是空白的here。据我所知,这是一个全新的课程,几乎没有文档,实际使用很少,这就是为什么几乎没有任何相关内容出现在谷歌搜索或此类Stackoverflow上。

我想知道是否有人使用过这个CURLFile类,并且可以帮助我或者给我一个例子来代替我的代码中的@filename。

编辑:

我想添加我的“upload.php”代码;此代码适用于传统的@filename方法,但不再使用CURLFile类代码:

$folder = "try/";
$path = $folder . basename( $_FILES['file']['tmp_name']); 
if(move_uploaded_file($_FILES['file']['tmp_name'], $path)) {
echo "The file ".  basename( $_FILES['file']['tmp_name']). " has been uploaded";
}

最终修改

希望为寻找几乎没有记录的CURLFile类的类似工作示例的其他人添加最终/工作代码......

curl.php(本地服务器)

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label> <input type="file" name="Filedata" id="Filedata" /> 
<br />
<input type="submit" name="submit" value="Submit" />
</form>

<?php
if ($_POST['submit']) {
    $uploadDir = "/uploads/";
    $RealTitleID = $_FILES['Filedata']['name'];
    $ch = curl_init("http://www.remotesite.com/upload.php"); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $args['file'] = new CurlFile($_FILES['Filedata']['tmp_name'],'file/exgpd',$RealTitleID);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $args); 
    $result = curl_exec($ch);       
}
?>

upload.php(远程服务器)

$folder = "try/";
$path = $folder . $_FILES['file']['name']; 
if(move_uploaded_file($_FILES['file']['tmp_name'], $path)) {
echo "The file ".  basename( $_FILES['file']['name']). " has been uploaded";
}

RFC上有一段代码:https://wiki.php.net/rfc/curl-file-upload

curl_setopt($curl_handle, CURLOPT_POST, 1);
$args['file'] = new CurlFile('filename.png', 'image/png', 'filename.png');
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $args);

如果你有创建对象的恐惧症,你也可以使用看似毫无意义的函数curl_file_create( string $filename [, string $mimetype [, string $postname ]] )

curl_setopt($curl_handle, CURLOPT_POST, 1);
$args['file'] = curl_file_create('filename.png', 'image/png', 'filename.png');
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $args);

感谢您的帮助,使用您的工作代码我能够通过php 5.5和Facebook SDK解决我的问题。我从sdk类的代码中得到了这个错误。

我不认为这算作回复,但我确定有人在搜索像facebook SDK和php 5.5这样的错误

如果有人遇到同样的问题,我的解决方案是从base_facebook.php更改一些代码,使用CurlFile类而不是@filename。

由于我从几个地方调用了sdk,我刚刚修改了几行sdk:

在名为“makeRequest”的方法中,我做了这个改动:

在这部分代码中:

if ($this->getFileUploadSupport()){
    $opts[CURLOPT_POSTFIELDS] = $params;
} else {
    $opts[CURLOPT_POSTFIELDS] = http_build_query($params, null, '&');
}

将第一部分(启用文件上传)更改为:

if ($this->getFileUploadSupport()){
  if(!empty($params['source'])){
     $nameArr = explode('/', $params['source']);
     $name    = $nameArr[count($nameArr)-1]; 
     $source  = str_replace('@', '', $params['source']);
     $size    = getimagesize($source); 
     $mime    = $size['mime'];
     $params['source'] = new CurlFile($source,$mime,$name);
  }

  if(!empty($params['image'])){
     $nameArr = explode('/', $params['image']);
     $name    = $nameArr[count($nameArr)-1]; 
     $image   = str_replace('@', '', $params['image']);
     $size    = getimagesize($image); 
     $mime    = $size['mime'];
     $params['image'] = new CurlFile($image,$mime,$name);
  }
  $opts[CURLOPT_POSTFIELDS] = $params;
} else {
    $opts[CURLOPT_POSTFIELDS] = http_build_query($params, null, '&');
}

也许这可以改进解析每个 $ param 并在值中查找“@”..但我只为图像<做了/ strong>因为我需要的。

FOR curl_setopt():不推荐使用@filename API进行文件上传。请改用CURLFile类

$img='image.jpg';

$data_array = array(
        'board' => $board_id,
        'note' => $note,
        'image' => new CurlFile($img)
    );

$curinit = curl_init($url);
     curl_setopt($curinit, CURLOPT_RETURNTRANSFER, true);
     curl_setopt($curinit, CURLOPT_POST, true);
     curl_setopt($curinit, CURLOPT_CUSTOMREQUEST, "POST");
     curl_setopt($curinit, CURLOPT_POSTFIELDS, $data_array);
     curl_setopt($curinit, CURLOPT_SAFE_UPLOAD, false);
     $json = curl_exec($curinit);
     $phpObj = json_decode($json, TRUE);  
     return $phpObj;

已经在上面解释了CURLFile,但是对于简单的一个文件传输,您不想发送多部分消息(一个文件不需要,一些API不支持多部分),那么以下作品。

$ch = curl_init('https://example.com');

$verbose = fopen('/tmp/curloutput.log', 'w+'); // Not for production, but useful for debugging curl issues.

$filetocurl = fopen(realpath($filename), 'r');

// Input the filetocurl via fopen, because CURLOPT_POSTFIELDS created multipart which some apis do not accept.

// Change the options as needed.

$options = array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => array(
        'Content-type: application/whatever_you_need_here',
        'Authorization: Basic ' . $username . ":" . $password) // Use this if you need password login
    ),
    CURLOPT_NOPROGRESS => false,
    CURLOPT_UPLOAD => 1,
    CURLOPT_TIMEOUT => 3600,
    CURLOPT_INFILE => $filetocurl,
    CURLOPT_INFILESIZE => filesize($filename),
    CURLOPT_VERBOSE => true,
    CURLOPT_STDERR => $verbose  // Remove this for production
);

if (curl_setopt_array($ch, $options) !== false) {
    $result = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
} else {
    // A Curl option could not be set. Set exception here
}

注意上面的代码有一些额外的调试 - 一旦它工作就删除它们。

Php POST请求发送具有curl功能的多个文件:

<?php
    $file1 = realpath('ads/ads0.jpg');
    $file2 = realpath('ads/ads1.jpg');
    // Old method
    // Single file
    // $data = array('name' => 'Alexia', 'address' => 'Usa', 'age' => 21, 'file' => '@'.$file1);    
    // $data = array('name' => 'Alexia', 'address' => 'Usa', 'age' => 21, 'file[0]' => '@'.$file1, 'file[1]' => '@'.$file2);
    // CurlFile method   
    $f1 = new CurlFile($file1, mime_content_type($file1), basename($file1)); 
    $f2 = new CurlFile($file2, mime_content_type($file2), basename($file2)); 
    $data = array('name' => 'Alexia', 'address' => 'Usa', 'age' => 21, 'file[1]' => $f1, 'file[2]' => $f2);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://url.x/upload.php');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false); // !!!! required as of PHP 5.6.0 for files !!!
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)");
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // 1, 2
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    // curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    $res2 = curl_exec($ch);
    echo $res2;
?>

<?php
    // upload.php
    $json = json_decode(file_get_contents('php://input'), true);
    if(!empty($json)){ print_r($json); }
    if(!empty($_GET)){ print_r($_GET); }
    if(!empty($_POST)){ print_r($_POST); }
    if(!empty($_FILES)){ print_r($_FILES); }
?>
