PDFTron Web Viewer в ASP.NET или HTML-странице - при загрузке pdf или xod отображается ошибка

Question

При использовании PDFTron Web Viewer в ASP.NET или HTML-странице для отображения файла PDF или XOD я получаю сообщение об ошибке: "Не удалось загрузить файл ресурсов. Это может быть связано с неверным рабочим путем или неподдерживаемым типом.res mime на сервере. "

<script>
$(function () {
            var viewerElement = document.getElementById('viewer');
            var myWebViewer = new PDFTron.WebViewer({
                path: 'lib',
                type: 'html5',
                documentType: "pdf",
                initialDoc: "lib/GettingStarted.pdf",
                config: '',
                streaming: false, 
                enableAnnotations: false,
                enableOfflineMode: false,
                enableReadOnlyMode: true       
            }, viewerElement);
        });
</script>

Добавьте следующее в ваш web.config, обязательно удалите и добавьте некоторые из них, если вы работаете с IISExpress.

<system.webServer>    
<staticContent>
  <remove fileExtension=".js" />
  <mimeMap fileExtension=".js" mimeType="text/javascript" />
  <!-- PDFViewer -->
  <!--Remove statement for each extension is for running it on IIS Express-->
  <remove fileExtension=".json" />
  <mimeMap fileExtension=".json" mimeType="application/json" />
  <remove fileExtension=".woff" />
  <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
  <mimeMap fileExtension=".res" mimeType="text/plain" />
  <mimeMap fileExtension=".nmf" mimeType="text/plain" />
  <mimeMap fileExtension=".pexe" mimeType="text/plain" />
  <mimeMap fileExtension=".mem" mimeType="text/plain" />
