我正在尝试使用 json 将数组列表从 php 传输到 javascript，但它不起作用。
JS:
$.ajax({
url: 'getProfilePhotos.php',
type: 'post', // post or get method
data: {}, // if you need to pass post/get parameterds you can encode them here in JSON format
dataType: 'json', // the data type you want returned... we will use json
success: function(responseData) {
var arrayList[0] = new Array();
var lung = arrayList.length;
for(var i = 0; i<lung; i++)
//arrayList[i] = responseData.i;
console.log(responseData.i);
}});
PHP:
<p> <?php
$array = array();
$nr = count($friends['data']);
for($i = 0; $i < $nr; $i++){
$array = 'link'=>array("http://graph.facebook.com/".$friends['data'][$i]['id']."/picture");
?>
<img src="http://graph.facebook.com/<?php echo $friends['data'][$i]['id'] ?>/picture" />
<?php
}
header('Content-type: application/json');
echo json_encode($array);
?></p>
克里斯托弗·麦肯更新
我在控制台中遇到错误。这是错误。
[02:46:21.281] 属性列表 @ http://romanager.ro/api/examples/script.js:3 后缺少 }
script.js 中的第 3 行是
type: 'post', // post or get method
事实上我想从 Facebook 个人资料照片中获取。使用 php 脚本，我设法获取照片，但我可以将 id 从 php 传输到 javascript。如果您需要，我会尝试编写整个 php 脚本和 javascript 文件。
更新
这些脚本仍然存在问题。在 php 脚本中，我对 facebook 上的用户进行身份验证，因为我需要来自 facebook 的用户 ID 来获取他 friend 的 id。要登录，我需要在 php 脚本中创建 html。好吧，我将发布我的脚本代码，希望你能帮助我。
PHP 脚本:
<?php
require '../src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => '137061043024243',
'secret' => '619c4dc94343584eb7792ae9933978c9',
'cookie' => true,
));
// We may or may not have this data based on a $_GET or $_COOKIE based session.
//
// If we get a session here, it means we found a correctly signed session using
// the Application Secret only Facebook and the Application know. We dont know
// if it is still valid until we make an API call using the session. A session
// can become invalid if it has already expired (should not be getting the
// session back in this case) or if the user logged out of Facebook.
$session = $facebook->getSession();
$me = null;
// Session based API call.
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
$friends = $facebook->api('/me/friends');
} catch (FacebookApiException $e) {
error_log($e);
}
}
// login or logout url will be needed depending on current user state.
if ($me) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');
?>

最佳答案
您的 PHP 部分是错误的，因为您仍在尝试生成 HTML，而不是仅生成 JSON。
循环内的数组处理也不正确。
尝试将 PHP 代码更改为:
<?php
$friendData = array();
foreach ($friends['data'] as $cFriend) {
$friendData[$cFriend['id']] = "http://graph.facebook.com/" . $cFriend['id'] . "/picture";
}
header('Content-Type: application/json');
echo json_encode($friendData);
exit;
