How to pass the authorization header from report service requests in ASP.NET MVC ReportViewer?
You can use the Ajax-Before-Load event to pass the authorization header with report server requests using Syncfusion ASP.NET MVC ReportViewer. The following steps guide you to send the custom headers from client to the server-side using the ‘Ajax-before-load’ event.
1. Create a simple ReportViewer application with the help of getting started documentation.
2. Provide the custom headers in the client-side and pass as an argument for the Ajax-before-load event as shown in the following code snippet.
Default.html
<div id="ControlRegion" style="height:100% ;position:absolute;">
<div>
@(Html.EJ().ReportViewer("reportviewer").ProcessingMode(Syncfusion.JavaScript.ReportViewerEnums.ProcessingMode.Remote).ReportPath("~/App_Data/Grouping Aggregate.rdl").ReportServiceUrl("/api/ReportAPI").AjaxBeforeLoad("ajaxBeforeLoad"))
</div>
@(Html.EJ().ScriptManager())
</div>
<script type="text/javascript">
function ajaxBeforeLoad(event) {
event.headers.push({ Key: 'Authorization', Value: "BearerMyToken" });
};
</script>
3. Get the client-side custom header in the controller (ReportAPIController) from Authorization key using HttpContext in PostReportAction as shown in the following code snippet.
ReportAPIController.cs
public class ReportAPIController : ApiController, IReportController
{
public string HeaderContent = null;
//Post action for processing the rdl/rdlc report
public object PostReportAction(Dictionary<string, object> jsonResult)
{
if (jsonResult != null)
{
HeaderContent = HttpContext.Current.Request.Headers["Authorization"];
}
return ReportHelper.ProcessReport(jsonResult, this);
}
[System.Web.Http.ActionName("GetResource")]
[System.Web.Http.AcceptVerbs("GET")]
public object GetResource(string key, string resourcetype, bool isPrint)
{
return ReportHelper.GetResource(key, resourcetype, isPrint);
}
public void OnInitReportOptions(ReportViewerOptions reportOption)
{
}
public void OnReportLoaded(ReportViewerOptions reportOption)
{
}
}
