How to pass authorization header from report service requests in ASP.NET Core ReportViewer?
You can use the Ajax-Before-Load event to pass the authorization header with report server requests using Syncfusion ASP.NET Core ReportViewer. The following steps guide you to send the custom headers from client to the server-side using the ‘Ajax-before-load’ event.
- Create a simple ReportViewer application with the help of getting started documentation.
2. Provide the custom headers in client-side and pass as an argument for the Ajax-before-load event as shown in the following code snippet.
Index.cshtml
@{
ViewData["Title"] = "ReportViewer ASP.NET CORE Support";
}
<style>
body, html, #reportviewer {
overflow: hidden !important;
height: 100%;
width: 100%;
}
</style>
<ej-report-viewer id="container" report-service-url="/Home" processing-mode="Remote" ajax-before-load="ajaxBeforeLoad"></ej-report-viewer>
<ej-script-manager></ej-script-manager>
<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 (HomeController) from Authorization key using HttpContext in PostReportAction as shown in the following code snippet.
HomeController.cs
public partial class HomeController : Controller, IReportController
{
private IMemoryCache _cache;
private IHostingEnvironment _hostingEnvironment;
private Microsoft.Extensions.Primitives.StringValues headerContent;
public HomeController(IMemoryCache memoryCache, IHostingEnvironment hostingEnvironment)
{
_cache = memoryCache;
_hostingEnvironment = hostingEnvironment;
}
public ActionResult Index()
{
return View();
}
public IActionResult Error()
{
return View();
}
[HttpPost]
public object PostReportAction([FromBody] Dictionary<string, object> jsonResult)
{
if (jsonResult != null)
{
HttpContext.Request.Headers.TryGetValue("Authorization", out headerContent);
}
return ReportHelper.ProcessReport(jsonResult, this, this._cache);
}
}
