我正在尝试用 Javascript 构建一个 Facebook 应用程序,它可以让我使用 FQL 检索每个朋友的状态列表。但似乎每个 FQL 查询都没有返回任何结果。这是我的代码,由各种教程模板拼凑而成:
<html>
<title>Testing Facebook Javascript SDK</title>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
// init the FB JS SDK
FB.init({
appId : 'MY_APP_ID', // App ID from the App Dashboard
channelUrl: '//www.myurl.net/channel.html',
status : true, // check the login status upon init?
cookie : true, // set sessions cookies to allow your server to access the session?
xfbml : true // parse XFBML tags on this page?
});
// Additional initialization code such as adding Event Listeners goes here
FB.getLoginStatus(function(response){
if (response.status === 'connected'){
showMyFriends();
FB.api('/me/permissions',function(response){
console.log(response);
});
} else if (response.status === 'not_authorized'){
login();
} else {
login();
}
});
};
function login(){
FB.login(function(response){
if (response.authResponse){
alert('login');
} else {
alert('cancelled');
}
},{scope:'read_stream'});
}
function showMyFriends(){
FB.api('/me/friends',function(response){
if(response.data){
var length = response.data.length;
for(var i=0;i<50;i++){
element=response.data[i];
getAFriendStatus(element.id);
}
}
});
}
function getAFriendStatus(friendUID){
FB.api('/fql',{q:{"query1":"select message from status where uid="+friendUID}},
function(response){
console.log(response);
}
);
}
// Load the SDK's source Asynchronously
// Note that the debug version is being actively developed and might
// contain some type checks that are overly strict.
// Please report such bugs using the bugs tool.
(function(d, debug){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "https://connect.facebook.net/en_US/all" + (debug ? "/debug" : "") + ".js";
ref.parentNode.insertBefore(js, ref);
}(document, /*debug*/ false));
</script>
</body>
当我检查控制台时,每次调用我得到的getAFriendStatus()
只是:
Object {data: Array[1]}
data: Array[1]
0: Object
fql_result_set: Array[0]
name: "query1"
__proto__: Object
length: 1
__proto__: Array[0]
__proto__: Object
因为 的fql_result_set
大小为 0,所以我认为我的查询有问题。我不认为这是一个权限问题,因为控制台输出FB.api('/me/permissions')
是:
Object {data: Array[1], paging: Object}
data: Array[1]
0: Object
basic_info: 1
installed: 1
read_stream: 1
所以我知道我有read_stream
权限。为什么我没有通过此查询获得状态?
编辑:我刚刚尝试了 FQL 查询
"select message from status where uid=me()"
我得到了我最近的所有状态帖子。似乎只是获取我朋友的状态的问题?这可能是由于他们的隐私设置吗?
