上传图像与Facebook API [英] Upload image with facebook API

问题描述

问：如何从我的web服务器通过FB API上传图片至Facebook

Question: How to upload an image from my webserver to facebook via FB API?

我正在写检索用户的相册图像的应用程序，使得一些修改（例如添加水印），然后将其发送回相册。

I'm writing an application that retrieves images from the user's photo album, makes some modifications (e.g. adding a watermark) then send it back to photo album.

在code我用上传照片如下：

The code I use to upload the photo is as follows

<?php
include_once("api/facebook.php");
include_once("config.php");
include_once("utils.php");
include_once("bemyfans.php");
$facebook=new Facebook($api_key,$app_secret);
$facebook->require_frame();
$user=$facebook->require_login();
echo "<p>Hello <fb:name useyou='false' uid=\"$user\"/></p>";
$args = array(
  'api_key' => $api_key,
  'call_id'=>microtime(true),
  'v'=>'1.0',
  'format' => 'JSON'
);
$args['Lenna.png']="@/home/thoai/htdocs/apps/bemyfans/Lenna.png";
signRequest($args,$secret);
$ch = curl_init();
$url = 'http://api.facebook.com/restserver.php?method=photos.upload';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
if ($data = curl_exec($ch)) echo "done";
echo $data;

function signRequest(&$args, $secret){
  ksort($args);
  $sig = '';
  foreach($args as $k => $v){
    $sig .= $k . '=' . $v;
  }
  $sig .= $secret;
  $args['sig'] = md5($sig);
}
?>

这是行不通的。更具体地讲，我不断收到一个错误的信号消息。

It just doesn't work. More specifically, I keep getting an "Incorrect signature" message.

什么是错的code ???

What's wrong with the code???

推荐答案

在这个问题的code使用过时的REST API的后，将很快停止。

The code in this question use the outdated REST APIs, that will soon be discontinued.

正确的方法是现在：

$fbk = new Facebook(/* conf */);
$fbk->setFileUploadSupport(true);

//If you are executing this in a script, and not in a web page with the user logged in:
$fbk->setAccessToken(/* access token from other sources */);

//To add to an album:
$fbk->api("/$albumId/photos", "POST", 
          array('source' => '@'. realpath($myPhoto), 'message'  => "Nice photo"));

//To upload a photo directly (the album will be created automatically):
$fbk->api("/me/photos", "POST", 
          array('source' => '@'. realpath($myPhoto), 'message'  => "Nice photo"));

记住 $ fbk-＆GT; setFileUploadSupport（真）;
