我刚刚尝试使用Facebook PHP SDK开发一个Facebook应用程序。Facebook开发者网站给出的示例代码如下:
<?php
// Remember to copy files from the SDK's src/ directory to a
// directory in your application on the server, such as php-sdk/
require_once('php-sdk/facebook.php');
$config = array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
'fileUpload' => true,
'allowSignedRequest' => false // optional but should be set to false for non-canvas apps
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
$photo = './mypic.png'; // Path to the photo on the local filesystem
$message = 'Photo upload via the PHP SDK!';
?>
<html>
<head></head>
<body>
<?php
if($user_id) {
// We have a user ID, so probably a logged in user.
// If not, we'll get an exception, which we handle below.
try {
// Upload to a user's profile. The photo will be in the
// first album in the profile. You can also upload to
// a specific album by using /ALBUM_ID as the path
$ret_obj = $facebook->api('/me/photos', 'POST', array(
'source' => new CURLFile($photo, 'image/png'),
'message' => $message,
)
);
echo '<pre>Photo ID: ' . $ret_obj['id'] . '</pre>';
echo '<br /><a href="' . $facebook->getLogoutUrl() . '">logout</a>';
} catch(FacebookApiException $e) {
// If the user is logged out, you can have a
// user ID even though the access token is invalid.
// In this case, we'll get an exception, so we'll
// just ask the user to login again here.
$login_url = $facebook->getLoginUrl( array(
'scope' => 'photo_upload'
));
echo 'Please <a href="' . $login_url . '">login.</a>';
error_log($e->getType());
error_log($e->getMessage());
}
} else {
// No user, print a link for the user to login
// To upload a photo to a user's wall, we need photo_upload permission
// We'll use the current URL as the redirect_uri, so we don't
// need to specify it here.
$login_url = $facebook->getLoginUrl( array( 'scope' => 'photo_upload') );
echo 'Please <a href="' . $login_url . '">login.</a>';
}
?>
</body>
</html>
但是当我运行程序时，它显示了一个错误'Fatal error: Class 'CURLFile' not found'。当搜索解决方案时，我发现新的PHP Facebook SDK没有'CURLFile'类。谁能帮我用新的SDK代码"发布照片到用户时间轴"?
Thanks in advance.
也许你需要加一个反斜杠:
new 'CurlFile($photo)
如果它不工作也许检查CurlFile是否存在。如果不存在，则需要直接传递tmp filename.fileExtension。
'source' => class_exists('CurlFile', false) ? new CURLFile($photo, 'image/png') : "@{$photo}"
在else条件下，$photo的形式为filename.fileExtension。
CURLFile类仅适用于PHP 5>= 5.5.0
正如Facebook的例子所说:
// If you're not using PHP 5.5 or later, change the file reference to:
// 'source' => '@/path/to/file.name'
您是否尝试通过取消
行注释来启用PHP中的cURL ?;extension=php_curl.dll
在xampp'apache'bin'php.ini中，然后重启apache服务。
可以通过phpinfo()
检查也检查基于CURLFile类的php版本doc
试试这个:
$ret_obj = $facebook->api('/me/photos', 'POST', [
'image' => '@' . realpath($photo),
'message' => '$message'
]);
这对我很有用。
除了使用realpath，注意'source'现在是 'image' 。
