我正在创建一个facebook应用程序。我使用 omniauth-facebook gem登录用户。我问以下权限:
provider :facebook, 'app_id', 'secret_key',
scope: "public_profile,user_friends,friends_photos,user_photos"
用户登录后,我正在接待他的朋友'带有koala
gem的列表,类似于以下代码:
@graph = Koala::Facebook::API.new(current_user.oauth_token)
@profile = @graph.get_object("me")
@friends = @graph.get_connections("me", "friends?fields=id,name,gender")
我不知道我是否可以为他的每个朋友获取相册和照片。我已经尝试了以下fql查询:
SELECT pid FROM photo WHERE aid IN (SELECT aid,name FROM album WHERE owner=user_id)
当我在图形api资源管理器上测试它时,它只适用于我,但它不适用于我的应用程序(既不适合我的朋友也不适合我)。
我是否错过了某些权限,或者无法获取某人朋友的照片和相册?有关通过脸谱图API获取某人朋友的所有照片的其他建议吗?
更新
我已在此处上传了代码https://github.com/johndel/fbgame 你可以在 config / initializers / omniauth.rb 和 app / controllers / pages_controller.rb
上看到上面的代码及其余部分。答案 0 :(得分:2)
问题与您的应用在注册期间提出的权限有关。如果您查看它,它不会要求您的朋友的照片。
以上意味着问题与omniauth-facebook gem有关,因为这就是你正在使用的。您使用的是旧版本(版本1.4.0),即使我更新了它仍然无法使用当前版本(1.6.0)。
我使用了javascript版本,它正在生成一个正确的omniauth键并询问更好的权限(朋友的照片访问权限)。登录后,它与考拉宝石很好地配合,所以你可能必须通过其他方法获得omniauth密钥,因为当前的omniauth-facebook宝石似乎有一些bug(我认为javascript方法是我'使用过的,是建议的方法)。
这是带有javascript的代码(大部分是来自facebook图api的复制粘贴):

// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
testAPI();
} else if (response.status === 'not_authorized') {
// The person is logged into Facebook, but not your app.
document.getElementById('status').innerHTML = 'Please log ' +
'into this app.';
} else {
// The person is not logged into Facebook, so we're not sure if
// they are logged into this app or not.
document.getElementById('status').innerHTML = 'Please log ' +
'into Facebook.';
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : 'api_key',
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.0' // use version 2.0
});
// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
FB.api('/me/albums', function(response) {
console.log(JSON.stringify(response));
// document.getElementById('status').innerHTML =
// 'Thanks for logging in, ' + response.name + '!';
});
}
</script>
<!--
Below we include the Login Button social plugin. This button uses
the JavaScript SDK to present a graphical Login button that triggers
the FB.login() function when clicked.
-->
<fb:login-button scope="public_profile,user_friends,friends_photos,user_photos" onlogin="checkLoginState();">
</fb:login-button>
<div id="fb-root">

<div id="status">

<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

$(function() {
// FB.api('/me', function(response) {
// console.log(JSON.stringify(response));
// });
});
</script>
</div>

成功生成具有正确权限的omniauth密钥后,它可以正常工作。你可以用考拉或javascript方式测试它,就像我通过调用上面的方法一样。
