Javascript-如何从http get解析图api facebook中的json？

Question

我正在使用图api来搜索组，这是http请求：

var url ="https://graph.facebook.com/search?type=group&q=house&access_token=access_token&callback=FB.__globalCallbacks.f317bdb78&limit=5&method=get&pretty=0&sdk=joey".

$.get(url, function( resp ) {
   console.log(resp);//it's return resp
   var obj = jQuery.parseJSON(resp.data);//I got error here, resp.data is undefined
   console.log(obj);
});

这是来自图API的响应：

/**/ FB.__globalCallbacks.f317bdb78({"data":[{"name":"House Party !!!","privacy":"CLOSED","id":"881671771927203"},{"name":"KITTY'S HOUSE","privacy":"OPEN","id":"100126236854592"},{"name":"Full House Long Xuy\u00ean","privacy":"OPEN","id":"606749376035865"},{"name":"Housing Ho Chi Minh City (Saigon)","privacy":"CLOSED","id":"330339417123482"},{"name":"Ch\u0103n Drap House","privacy":"OPEN","id":"1397025403874006"}],"paging":{"cursors":{"before":"MAZDZD","after":"NAZDZD"},"next":"https:\/\/graph.facebook.com\/v2.0\/search?access_token=access_token&pretty=0&q=house&type=group&limit=5&after=NAZDZD"}});

如何解析来自响应图搜索Facebook的JSON数据？

Answer 1

如果您使用的是JSONP（请注意callback=? GET参数），则您的代码应为：

var url ="https://graph.facebook.com/search?type=group&q=house&access_token=access_token&callback=?&limit=5&method=get&pretty=0&sdk=joey";

$.getJSON(url, function( resp ) {
   console.log(resp);
});

或更通用的：

var url ="https://graph.facebook.com/search?type=group&q=house&access_token=access_token&callback=?&limit=5&method=get&pretty=0&sdk=joey";

$.ajax({
   url: url,
   dataType: 'jsonp'
}).then(function(resp) {
   console.log(resp);
})

Answer 2

为什么首先使用JSONP？

var url ="https://graph.facebook.com/search?type=group&q=house&access_token=access_token&limit=5".

$.getJSON(url, function(resp) {
   console.log(resp.data);
});

恕我直言...
