How to get the client context for code in a provider-hosted add-in that is called outside of the SharePoint context.<\/p>\n\n\n\n
For example, you want a page in your solution to be called directly and not from SharePoint. Reasons for this may be that you have a page in the add-in that you want to share with users and don’t want to give the full add-in url. Instead of:<\/p>\n\n\n\n
http:\/\/myaddindomain.com\/pages\/custompage.aspx?SPHostUrl={etc}<\/p>\n\n\n\n
You want something like this, without all the parameters:<\/p>\n\n\n\n
http:\/\/myaddindomain.com\/pages\/custompage.aspx<\/p>\n\n\n\n\n\n\n\n
With the former, you’ll be able to get the context with:<\/p>\n\n\n
\nvar context = SharePointContextProvider.Current.GetSharePointContext(Context);\n<\/pre><\/div>\n\n\nTrying this without all the parameters will obviously fail and you’ll get a 401 unauthorised error.<\/p>\n\n\n\n
To get a valid context this way, you’ll need to have the SharePoint host’s URL stored somewhere in the remote website. In the web.config for example.<\/p>\n\n\n\n
To obtain the context, use this instead:<\/p>\n\n\n
\nvar hostUri = new Uri(ConfigurationManager.AppSettings["HostUrl"]);\nusing (var context = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostUri, Request.LogonUserIdentity){\n\/\/ CSOM code\n}\n<\/pre><\/div>\n\n\nThis will create the context for the current user and you should now be able to query the SharePoint site’s content.<\/p>\n","protected":false},"excerpt":{"rendered":"
