Saiku嵌入系统使用时传参数访问saiku
Saiku通过iframe嵌入其他系统使用时,我们可以设定参数信息,然后根据url中参数对结果进行筛选哦。
这里我们实现的是根据日期字段进行范围查询,URL请求中需要多加如下两个参数 startdate , enddate ,也就是开始日期与结束日期。
实现日期的范围查询 saiku date range,主要有以下步骤
1. 修改源代码 saiku-ui 项目下的 js\saiku\models\Query.js(如果你不是本地编译的源码也可以直接修改 saiku-server\tomcat\webapps\ROOT\js\saiku\models 目录下的 Query.js )
在Query.js下的 run方法中增加如下代码段:
//根據用戶輸入的開始日期與結束日期查詢範圍數據 var dimensionArr = exModel.queryModel.axes.ROWS.hierarchies; //取出行信息中的所有维度信息 dimension,用一个数组接收 for(var i=0;i
这里最主要的是就是找到需要改动的位置了:(文末提供了修改后完整的Query.js文件)
从 exModel.queryModel.axes.ROWS.hierarchies 这个数组中找到countdate ,然后再修改countdate对应 levels.coundate下的mdx值。
层级关系如下图:(0是可变的哟,可能是下标1,2,3..... 所以上面代码中用到了 for循环去找 countdate )
2. saiku中xml文件中的cube中必须配置日期字段,我用的是countdate字段,配置如下
3.Saiku配置数据信息的时候需要将日期字段拖到 行 数据框
4.使用url发请求访问saiku中需带入startdate,enddate参数 (如果不带入这两个参数的话就不会进行范围筛选啦!!!然后就会正常查询全量数据)
模板URL如下:
http://10.99.77.78:8080/?username=admin&password=aaa&startdate=2019-03-06%2000:00:00.0&enddate=2019-03-10%2000:00:00.0&plugin=false&mode=view#query/open//KPI/aa.saiku
URL解析
http://10.99.77.78:8080/ #是我的saiku的访问地址
username=admin&password=aaa #分别是我登录saiku的用户名以及密码
startdate=2019-03-06%2000:00:00.0&enddate=2019-03-10%2000:00:00.0 #是我设定的开始时间以及结束时间,我想查询countdate值为3.6到3.10的数据。这里需要说明一下我的countdate中有2019-03-06 00:00:00.0 ,2019-03-10 00:00:00.0 这两个值哦。
plugin=false&mode=view#query/open/ #这里指不以插件的方式嵌入,嵌入的模式为view(会带出导出excel那一排工具栏信息)
/KPI/aa.saiku #这个就是我保存的数据信息啦,我自己新建了个KPI目录,然后保存的数据命名为 aa .
5.过滤结果如下图:
解析:( 其实上面添加的注释已经比较详细的,嘻嘻 ,需要注意的主要有以下4点)
1. 数据库中必须有一个countdate日期字段(名字当然可以随意)
2.Schema文件中 对应的cube信息中必须配置 countdate字段如下:(关键的是 Dimension下的name Hierarchy下的allMemerName Level下的name 命名都为countdate )
3.如果需要根据日期进行范围筛选,url中必须添加参数 startdate,enddate 哦
4.想要获取正确的筛选结果,startdate以及enddate的值必须是当前cube中已有的值!!!(不然就会报错啦,就像你在saiku中使用参数一样,参数值一定要填写当前结果中已有的值,关于日期就很较真啦,时分秒都要对应上才行哦)
>>>更改后的Query.js文件
这里再提供一下修改之后的完整Query.js ,其它地方都没有改动,就只是添加了上方内容,详情如下
