Question

我有一个提供SSRS报告的应用程序。可通过以下方式访问给定报告：

https://reportserver.com/reportname

点击查看报告后，会使用用户定义的参数向报表服务器提交回发。我需要获取这些用户定义的参数并将它们解析为URL字符串。

期望的结果： https://reportserver.com/reportname?param1=foo&param2=bar

我发现this doc让我接近我需要的东西。这个方法应该允许我抓住所有可见参数并自己解析它们，但我也需要隐藏参数。

如何构建此参数字符串？我们在前端使用JavaScript / jQuery，因此可以在POST之前抓住这个客户端，但我还没有找到一种方法。

我使用参数3种不同的方式为报告创建了URL。前两者的组合可以让您更接近解决问题。

在报告属性中使用自定义代码。

Public Function ShowParameterValues(ByVal parameter as Parameter)  
 as String  
   Dim s as String   
   If parameter.IsMultiValue then  
      s = "Multivalue: "   
      For i as integer = 0 to parameter.Count-1  
         s = s + CStr(parameter.Value(i)) + " "   
      Next  
   Else  
      s = "Single value: " + CStr(parameter.Value)  
   End If  
   Return s  
End Function

OR

在报告中使用超链接。

=Globals!ReportServerUrl + "/ReportServer?" 
+ Replace(Globals!ReportFolder, " ", "+") + "%2f" 
+ Replace(Globals!ReportName, " ", "+") + "&rs:Command=Render"
+ "&single_value_parameter=" + Parameters!single_value_parameter.Value 
+ "&multi_value_parameter=" + Join(Parameters!multi_value_parameter.Value, "&multi_value_parameter=") 
+ IIf(IsNothing(Parameters!week_date_start.Value), "&week_date_start:isnull=True", "&week_date_start=" & Format(Parameters!week_date_start.Value, Variables!FormatDate.Value))
+ IIf(IsNothing(Parameters!week_date_end.Value), "&week_date_end:isnull=True", "&week_date_end=" & Format(Parameters!week_date_end.Value, Variables!FormatDate.Value))

另外，我通常将其添加为报表变量，然后您可以为页脚添加标准文本框，而不必更改。

=Variables!UrlReportWithParameters.Value

OR

使用执行日志。查看专栏URL_Report_Filtered
