Get JSON Facebook Graph API User Info with jQuery
提问by BillPull
I am trying to use the graph API to get just some basic info about a user no need for authorization by the user just the public details. I am trying to use jQuery and the .getJSON to get the data and parse it but I am having a hard time trying to figure out how to access the key value pairs I want.
我正在尝试使用图形 API 来获取有关用户的一些基本信息，无需用户授权，只需公开详细信息。我正在尝试使用 jQuery 和 .getJSON 来获取数据并解析它，但我很难弄清楚如何访问我想要的键值对。
I want to have something like
我想要类似的东西
var fburl = "http://graph.facebook.com/USER/callback=?"
$.getJSON(fburl, function(data){
$.each(data, function(i,item){
var name = item.user["name"];
$("#profile").append("<h3>"name"</h3>");
});
});
ive tried things like item.name and a bunch of other what I figured to be potential syntax options but still getting undefined.
我尝试了 item.name 和其他一些我认为是潜在的语法选项但仍然未定义的东西。
Is there anything wrong with this approach I only really have experience using JSON with twitter API which works fine with the above approach.
这种方法有什么问题吗我真的只有使用 JSON 和 twitter API 的经验，它可以很好地与上述方法配合使用。
When I console log data I get something like this
当我控制台日志数据时，我得到这样的信息
first_name: "First"
gender: "male"
id: "8977344590"
etc...
name: "Full Name"

It doesn't return an array, but an object. You don't need to be looping over anything.
它不返回一个数组，而是一个对象。你不需要循环任何东西。
You can just get the name straight from the object:
您可以直接从对象中获取名称：
$.getJSON(fburl, function(data){
var name = data["name"];
$("#profile").append("<h3>"+name+"</h3>");
});

PS. you had a syntax error with $("#profile").append("<h3>"+name+"</h3>");as well (you forgot the +around name)
附注。你也有语法错误$("#profile").append("<h3>"+name+"</h3>");（你忘记了+周围name）

You have to use jsonPfor cross domain issues:
您必须jsonP用于跨域问题：
$.get(fburl, function(data){
console.log(data);
alert(data.name);
},'jsonp');
