Display Front End of SharePoint in other portal

Question

Please give me an idea about this: We have SharePoint server 2016 and we want to show the front-end of SharePoint 2016 in our portal.

If a user can click on a file then the file is open or uploaded to our portal.

You can display SharePoint pages on an external site through an iframe.

By default, SharePoint prevents cross-domain IFRAMING of pages as a security measure to prevent clickjacking. But developers can opt-out of clickjacking (not recommended. do it in your own risk) protection by adding the AllowFraming control to their .aspx pages. <WebPartPages:AllowFraming runat="server" />

You will need to modify the master-page (be sure to keep a backup/copy) and add the following tags, which allows the page content to be presented inside an Iframe element.

Location 1: Search the master page for PlaceHolderPageTitle as your location indicator and place the tag under it.

<asp:ContentPlaceHolder id="PlaceHolderPageTitle" runat="server">
<!– custom tag –>
<WebPartPages:AllowFraming runat="server" />

Location 2: Search the master page for WebPartAdder as your location indicator and place the tag under it.

<WebPartPages:WebPartAdder ID="WebPartAdder" runat="server" />
<!– custom tag –>
<WebPartPages:AllowFraming runat="server" />

After these steps, you can display the SharePoint page in external sites using

<iframe src="{{sharepoint url here}}"></iframe>
