SfPdfViewer component API Service sample not match signature ?

[Nicolas NOEL]

Hello,

I'm considering your UI kit to be used in my project, but I'have a problem with the SfPdfViewer component for webAssembly app.

• I'm follow this tutorial : 

https://blazor.syncfusion.com/documentation/pdfviewer/getting-started/client-side-application/

And the note info  : https://www.syncfusion.com/kb/10346/how-to-create-pdf-viewer-web-service-application-in-asp-net-core?_ga=2.76151125.1159554419.1612878611-165318989.1612878611

• But with the last today version 18.4.0.42 it's seems the signature of method not match the content send by pdfViewer :

This is your sample for the load method:

1.         [AcceptVerbs("Post")]
2.         [HttpPost]
3.         [Microsoft.AspNetCore.Cors.EnableCors("MyPolicy")]
4.         //Post action for Loading the PDF documents 
5.         public IActionResult Load([FromBody] Dictionary<string, string> jsonObject)

And only this works for me for the same method :

     

 [AcceptVerbs("Post")]

        [HttpPost("Load")]

        //Post action for Loading the PDF documents   

        public async System.Threading.Tasks.Task<IActionResult> LoadAsync()

        {

            string requestBody = await new StreamReader(HttpContext.Request.Body).ReadToEndAsync();

            var jsonObject = JsonConvert.DeserializeObject<Dictionary<string,string>>(requestBody);

• I'm using a blazorWebAssemblyapp ASP.NETCore hosted

I send you in attachement a sample project to reproduce

Thanks,

Best regards,

Nicolas

Hi Nicolas, 

 

 

Thanks for contacting Syncfusion support. 

 

We have analyzed the code in the provided sample, We suspect that the reported issue occurs due not enabling the CORS in your sample . So kindly add the below code in the startup.cs file with in (ConfigureServices) method. In our PDFViewerController.cs file , we have provided the code ([Microsoft.AspNetCore.Cors.EnableCors("MyPolicy")]) before all our action method. So that the reported issue occurs in your end. 

app.UseCors(); 

 

We have created a simple sample for your reference. Please refer to the below sample, 

Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/HOSTED~1329632241 

Kindly try it and revert us with more details if you still have concerns about this.

Hi Vasugi

You right the problem is the cors :

"We suspect that the reported issue occurs due not enabling the CORS in your sample"

Thanks you
