在让我的 jsonp 与我的客户端主干脚本一起工作时遇到问题，pagenator 保持 gettgin 无效密钥错误环顾四周人们说这与我的服务有关，不返回 jsonp。

例如 SyntaxError: invalid label，我写了一个 mvc4 web api 服务，这是它返回的内容，它看起来是否正确，还有什么我需要添加到我的 api 以支持 jsonp 吗？

   {
      "odata.metadata":"http://test.test.uk/api/odata/$metadata#lnews","value":[
        {
          "ID":1,"title":"This is a test news artical","mainContent":"<p>\r\n\tthis is a test article</p>\r\n","featured":1,"visiblehomepage":1,"thedatetime":"2013-08-05T10:36:05.98","expireon":"2013-08-15T00:00:00","category":17,"embargo":null,"embargotime":"PT0S","embargodate":null,"customthumbnail":null,"news_layout":3,"LNBE":0,"LNBN":0,"LNBS":0,"LNBW":0,"LNWV":0,"LNWS":1,"LNDY":0,"LNSW":0,"LNSH":0,"LNCV":0

      ]

这是一个 JSONP 网址：

http://odata.netflix.com/v2/Catalog/Genres?$format=json&$callback=?

这是一个图表：

客户端服务器
------ ------

发出 URL 请求 查找与此 URL 参数匹配的函数 ($callback)

异步执行如果找到，异步执行函数

从回调返回 从服务器端作为函数返回数据，或错误
