Blazor WebAssembly: PDF Viewer AjaxHeaders

[Hacinto]

Using 18.4.033

Our services are behind an API. Authentication headers could be passed using the AjaxHeaders property of PdfViewerAjaxRequestSettings or is it only for internal use?

Thanks for your support.

Hi Hacinto, 

 

Thank you for contacting Syncfusion support.  

 

We have exposed the property  PdfViewerAjaxRequestSettings  as public in our PDF Viewer. So, we request you to use this property by using below code snippet. We have shared the sample for your reference. 

  

Code Snippet: 

 

 

<PdfViewerAjaxRequestSettings AjaxHeaders="Headers"></PdfViewerAjaxRequestSettings> 

 

@code{ 

    SfPdfViewer PdfViewer; 

 

    public List<AjaxHeader> Headers = new List<AjaxHeader>() { new AjaxHeader { HeaderName = "Authorization", HeaderValue = "Bearer 64565dfgfdsjweiuvbiuyhiueygf" } }; 

     

}

Please try it and let us know if you have any concerns about this.

Dhivya.

Hi - this doesn't work on 

Nuget release 20.1.0.50 either

[Ben Hoe]

I set the headers as you specify, but I get the following error:

System.InvalidOperationException: Misused header name, 'Authorization'. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.
