Use the SharePoint Cross Domain JavaScript library (CDL) to access SharePoint data from a remotely hosted web page without the need for OAuth tokens.
This sample requires the following:
A SharePoint 2013 (or later) development environment that is configured for add-in isolation. (A SharePoint Online Developer Site is automatically configured. For an on premise development environment, see Set up an on-premises development environment for SharePoint Add-ins)
Visual Studio and the Office Developer Tools for Visual Studio installed on your developer computer
The sample includes an instance of an Announcements list with two sample announcements in it. The list instance is deployed to the add-in web. When the start page loads, JavaScript in the CrossDomainExec.js file, in the remote domain, makes an AJAX call to SharePoint to get the announcements and displays them on the page.
The page looks similar to the following.
Note: The start page of the add-in, CrossDomainCall.aspx, is a plain HTML file. It has an “aspx” extension because when a remote start page in a provider-hosted add-in is opened by SharePoint, SharePoint sends it a context token in the body of the HTTP request. To do this SharePoint must send a POST request. But the IIS Express that is hosting the remote page when you are debugging will not accept POST requests to a resource with a .html extension.
The sample demonstrates the following:
How to use the key classes of the CDL to make calls from a remotely hosted domain to the SharePoint add-in web domain.
How to parse the JSON-formatted data returned from the SharePoint and how to display it dynamically.
For troubleshooting steps, visit the “Troubleshooting the solution” table in the cross-domain library documentation article.
