是否可以创建一个网站，并使用 JavaScript 从 Facebook 页面读取提要并将其显示给我的网站访问者，而无需他们登录，甚至不需要 Facebook。
我在 Facebook 文档中迷失了方向:(
最佳答案
感谢@mch，这里提供了使用 php 作为代理来通过 JavaScript 读取 Facebook feed 的版本。
在您的服务器上放置一个名为 proxy.php 的文件并添加以下代码:
<?php
// always add this header to ensure the JSON is output in the correct format
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-cache");
header("Pragma: no-cache");
header('Content-Type: application/json; charset=utf-8');
$graphUrl = $_POST[graphUrl];
if ($graphUrl == "") {
$graphUrl = "https://graph.facebook.com/facebook/feed/";
}
//App Info, needed for Auth
$app_id = "1234567890";
$app_secret = "0000011122234334445556aaass";
//retrieve auth token
$authToken = fetchUrl("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id={$app_id}&client_secret={$app_secret}");
//Echo back json to read client side.
echo fetchUrl("{$graphUrl}?{$authToken}");
function fetchUrl($url){
$ch = curl_init();
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
$retData = curl_exec($ch);
curl_close($ch);
return $retData;
}
?>
将 app_id、app_secret 更改为您的应用 ID。在此创建应用程序 https://developers.facebook.com/apps/
在代理文件旁边创建一个 HTML 文件。添加此代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>FB reader</title>
</head>
<body>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var timeout = 5000,
load_error;
load_error = function (jqXHR, textStatus, errorThrown) {
if (errorThrown === "timeout") {
alert('Server bussy');
} else {
alert('error: 404', textStatus + ": " + errorThrown);
}
};
$(document).ready(function() {
console.log('Loading from Facebook...\n');
//Change data: {graphUrl: 'https://graph.facebook.com/iambounty/feed'}, to what ever you want.
$.ajax({
type: 'POST',
url: 'proxy.php',
data: {graphUrl: 'https://graph.facebook.com/iambounty/feed'},
timeout: timeout,
error: load_error,
success: function (rv) {
var data = rv.data,
len = data.length,
i,
out = '';
for (i = 0; i < len; i += 1) {
if (data[i].description) {
out += data[i].description + '\n\n';
}
}
console.log(out);
}
});
});
});
</script>
</body>
</html>
