Javascript 在.getJson（）中传递同一参数的多个值

我正在尝试以下内容：

<script>
  var topic_id = '/m/04136kj';
  var service_url = 'https://www.googleapis.com/freebase/v1/topic';
  var params = {
                filter: "/common/topic/article",
                filter:"/common/topic/notable_for",
                filter: "/common/topic/notable_types",
                filter: "/type/object/type"
               };

  $.getJSON(service_url + topic_id + '?callback=?', params, function(topic) {
    //do something with response.
  });
</script>

将筛选器对象创建为数组

var topic_id = '/m/04136kj';
var service_url = 'https://www.googleapis.com/freebase/v1/topic';
var params = {
    filter: ["/common/topic/article", "/common/topic/notable_for", "/common/topic/notable_types", "/type/object/type"]
};
//used to remove the the suffix [] in the array param
$.ajaxSetup({ traditional: true });
$.getJSON(service_url + topic_id + '?callback=?', params, function (topic) {
    //do something with response.
});

param对象需要像HTML

对象一样创建，作为一系列名称/值对

var topic_id = '/m/04136kj';
var service_url = 'https://www.googleapis.com/freebase/v1/topic';
var filter = ["/common/topic/article", "/common/topic/notable_for",
    "/common/topic/notable_types", "/type/object/type"];
var params = filter.map(function(f) { return { name: "filter", value: f }; });

$.getJSON(service_url + topic_id + '?callback=?', params, function (topic) {
    //do something with response.
});

谢谢它起作用了，我理解其中的逻辑。我真是太蠢了：做了个小问题。Url的编码如下：

https://www.googleapis.com/freebase/v1/topic/m/04136kj?callback=jsonp1403174148707&filter[]=/common/topic/article

我注意到过滤器后面有一个

[]

。你知道为什么吗？我和费德勒确认了。它正在通过过滤器传递

[]

，这会导致错误响应。有什么想法吗？因为嵌入了

var topic_id = '/m/04136kj';
var service_url = 'https://www.googleapis.com/freebase/v1/topic';
var filter = ["/common/topic/article", "/common/topic/notable_for",
    "/common/topic/notable_types", "/type/object/type"];
var params = filter.map(function(f) { return { name: "filter", value: f }; });

$.getJSON(service_url + topic_id + '?callback=?', params, function (topic) {
    //do something with response.
});
