我目前正在使用带有Fusion Table Layer的Google Map.通过这张地图,我制作了填充地图的
AJAX查询和一个包含结果的列表.
最近,谷歌地图API响应出现了400“格式错误的请求”错误.在设置过滤器并通过AJAX发送后,在使用新结果集填充地图时偶尔会发生此响应.在检查错误Firefox的调试控制台时,我注意到pb参数可能是问题.问题是我不确定这个参数到底有什么错误.
https://maps.googleapis.com/maps/vt?pb=[...insert_param_code_here...]&callback=_xdc_._n2pwun&token=20077
我将我看到的内容粘贴到下面的pb参数中.这是在发出其中一个“无效”查询时发送的内容.

以下是没有URL编码的查询仅供参考：
SELECT School_Info_ID,CPS_ID,RCDTS,School_Name,Street_Address,City,State,Zip,Phone,Website,Lat,Long,Year_Opened,School_Description,District_Info_ID,District_Name,Charter_Renew_YR,Network_ID,Network,Community_Area,State_Rep_District,State_Sen_District,Ward_Remapped,Grades_Served,Grades_Capacity,Serves_ES,Serves_HS,Serves_MS,Serves_Dropouts,School_Type_Dropdown,School_Type_Color,School_Type_Display,Profile_Type,SQRP_Rating,SQRP_Profile,Cities_With_Charters,Link_IIRC,Students_Served FROM tableID WHERE Cities_With_Charters = 'East St. Louis Area' AND Students_Served LIKE '%' AND School_Type_Dropdown IN ('Charter') ORDER BY School_Name ASC
到目前为止我采取的步骤来解决这个问题：
>确保发送到Fusion Tables的任何查询字符串都已使用URL编码发送.
>确保检查我的引号和引号,并确保在发送的查询中没有任何流浪的.
>检查我的Google Map init参数,以确保我没有输入任何拼写错误或添加任何不存在的参数.
在确保格式不正确的内容未发送时,是否还有其他预防措施？
解决方法
我通过打开Chrome开发者工具解决了这个问题,并转到：应用程序> <清除存储>清除网站数据.然后,在开发人员工具仍然打开的情况下,单击并按住浏览器左上角的刷新按钮,直到看到“清空缓存和硬重新加载”字样.点击那个,你很高兴.
