上传远程照片到上传 [英] Upload a remote photo to an upload

问题描述

是否可以使用 Facebook PHP 库将远程图片上传到 Facebook??

Is it possible to upload a remote picture to Facebook using the Facebook PHP Library??

代替使用

    $facebook->setFileUploadSupport(true);
    $args = array('message' => 'My Caption');
    $args['image'] = '@' . realpath($file);

    $data = $facebook->api('/me/photos', 'post', $args);

代替 realpath($file) 我想使用图像的远程路径，例如:

Instead of a realpath($file) I would like to use a remote path to an image for example:

http://myserver.com/image.jpg

我尝试用 http 链接替换 ​​realpath($file)，但出现以下错误:

I tried to replace the realpath($file) with a http link but I got the following error:

 Uncaught CurlException: 26: couldn't open file "http://mydomain.com/fb_images/EwrTsUqEuG.jpg"

推荐答案

使用 file_get_contents() 将文件下载到您的服务器，然后 file_put_contents() 将其存储在一个临时的本地文件中，用于上传 FB 传输过程，然后 unlink() 之后删除文件.

Use file_get_contents() to download the file to your server, then file_put_contents() to store it in a temporary, local file for the upload FB transfer process, then unlink() to delete the file afterwards.

<?php

# The URL for the Image to Transfer
$imageURL = 'http://server.com/the_image.jpg';
# Folder for Temporary Files
$tempFilename = $_SERVER['DOCUMENT_ROOT'].'/tempFiles/';

# Unique Filename
$tempFilename .= uniqid().'_'.basename( $imageURL );

# Get the Image
if( $imgContent = @file_get_contents( $imageURL ) ){
  if( @file_put_contents( $tempFilename , $imgContent ) ){

    $facebook->setFileUploadSupport(true);
    $args = array('message' => 'My Caption');
    $args['image'] = '@' . realpath( $tempFilename );

    $data = $facebook->api('/me/photos', 'post', $args);

    # Once done, delete the Temporary File
    unlink( $tempFilename );

  }else{
    # Failed to Save Image
  }
}else{
  # Failed to Get Image
}
