使用库5.4.1进行FQL查询时出错 [英] Error with FQL query with library 5.4.1

问题描述

几个月前，我开发了一个应用程序来检索我的见解Facebook页面的计数器. 此应用程序可与库"Facebook C#SDK" 5.0.40版完美配合. 现在，我想使用最新的库版本5.4.1，但是我的应用程序不再起作用. 我不明白为什么.

A few months ago I developed an application to retrieve the counters of my insights Facebook pages. This application works perfectly with the library "Facebook C# SDK" version 5.0.40. Now I want to use the last library version 5.4.1 but my application no longer works. I do not understand why.

我使用以下代码:

       var fb = new FacebookClient(m_accessToken);

        fb.GetCompleted +=
            (o, e) =>
            {
                if (e.Error == null)
                {
                    dynamic result = e.GetResultData();

                    // e.UserState contains the 'p_date' object which caracterize the Query  
                    string response = result.ToString();
             Console.WriteLine(response);
                }
             };

         var query0 = string.Format("SELECT metric, value FROM insights WHERE object_id=" + p_pageId + " AND metric='" + p_counter + "' AND end_time=end_time_date('" + p_date + "') AND period=period('" + p_period + "')");
         fb.QueryAsync(new[] { query0 });

例如，如果我请求相同的Facebook页面ID，相同的计数器，同一天，同一时间段

For example, if I make a request for the same facebook page Id, same counter, same day, same period

对于库5.0.40，我收到响应(计数器"page_fans"的示例:

with library 5.0.40, i receive a response (Example for counter "page_fans":

[{"name":"query0","fql_result_set":[{"metric":"page_fans","value":"12018"}]}]

对于库5.4.1，对于任何请求(任何计数器，任何一天，任何页面)，我总是收到空响应:

with library 5.4.1, I receive always an empty response for any request (any counter, any day, any page):

[{"name":"query0","fql_result_set":[]}]

任何人都可以帮助我，并告诉我我需要在代码中进行哪些更改，以使我的应用程序可以使用"Facebook C#SDK"库的最新版本运行.

Does anyone can help me and tell me what I need to change in my code to allow my application runs with recent versions of the "Facebook C# SDK" library.

最诚挚的问候

推荐答案

作为临时解决方案，在修复此错误之前，您可以在end_time中使用秒值，并且使用"寿命，天，周，days_28之一，月份" 表示period ...

As a temporary solution until this bug is fixed you can use value in seconds for end_time and one of "lifetime, day, week, days_28, month" for period...
