Question

我遇到了facebook multiquery语法的问题

当我使用单个查询时，例如.simply复制并将其粘贴到您的浏览器中，您将获得结果

https://api.facebook.com/method/fql.query?query=SELECT metric, value FROM insights WHERE object_id=243995185663734 AND metric='application_active_users' AND end_time=end_time_date('2011-11-30') AND period=period('month')&access_token=243995185663734%7C3fAfdJJqdrgA99XWdE5K6zzeNR8

它给了我确切的真实结果。但现在我想使用multiquery，因为我必须获取多个指标的数据，但它给了我错误。

我使用此查询

 https://api.facebook.com/method/fql.multiquery? queries  ="{"query1": "SELECT metric, value FROM insights WHERE object_id=208344135910932 AND metric='application_active_users' AND end_time=end_time_date('2011-11-30') AND period=period('month')","query2": "SELECT metric, value FROM insights WHERE object_id=208344135910932 AND metric='application_active_users' AND end_time=end_time_date('2011-11-30') AND period=period('month')"}"&access_token=243995185663734|3fAfdJJqdrgA99XWdE5K6zzeNR8

请告诉我我是否使用了一些错误的语法来进行多重查询。这是我在xml中得到的错误响应。

看起来你的JSON周围有一些空格和额外的引用，试试

https://api.facebook.com/method/fql.multiquery?queries={%22query1%22:%20%22SELECT%20metric,%20value%20FROM%20insights%20WHERE%20object_id=208344135910932%20AND%20metric='application_active_users'%20AND%20end_time=end_time_date('2011-11-30')%20AND%20period=period('month')%22,%22query2%22:%20%22SELECT%20metric,%20value%20FROM%20insights%20WHERE%20object_id=208344135910932%20AND%20metric='application_active_users'%20AND%20end_time=end_time_date('2011-11-30')%20AND%20period=period('month')%22}&access_token=243995185663734|3fAfdJJqdrgA99XWdE5K6zzeNR8

通过这个电话，我回来了：
