OData V4 to access secured URI - wpf

Question

I need to develolp a WPF application that use the OData service of a Project Online Server. When I try to reference the OData service with ODataLib V4, it doesn't work because the OData service is secure.
Anyone know a workaround for this problem ?

Answer 1

I found the solution.
Extract the metadata of Project Online in xml file (https://[your pwa site]/_api/ProjectData/$metadata)
Change the extension of the xml file to .edmx
Execute DataSvcUtil in your Framework directory (DataSvcUtil /in:edmxfile.edmx /out:csfile.cs /language:CSharp)
Add the csfile.cs in your .Net Project
Add the following references in your project :
- Microsoft.SharePoint.Client
- Microsoft.SharePoint.Client.DocumentManagement
- Microsoft.SharePoint.Client.Publishing
- Microsoft.SharePoint.Client.Runtime
- Microsoft.SharePoint.Client.Runtime.Windows
- Microsoft.SharePoint.Client.Taxonomy
- Microsoft.SharePoint.Client.UserProfiles
- Microsoft.SharePoint.Client.WorkflowServices
- Microsoft.SharePoint.WorkflowServices.Activities
- Microsoft SharePoint Solutions Framework
Here, an example of the code :
private const string PSDATA = "https://[your pwa site]";
ProjectOData.ReportingData context =
new ProjectOData.ReportingData(new Uri(PSDATA + "/_api/ProjectData/", UriKind.Absolute)) { IgnoreMissingProperties = true };
var username = <username>;
var password = <password>;
var secureString = new System.Security.SecureString();
foreach (char c in password.ToCharArray())
{
secureString.AppendChar(c);
}
context.Credentials = new SharePointOnlineCredentials(username, secureString);
SharePointOnlineCredentials credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials(username, secureString);
var authenticationCookie = credentials.GetAuthenticationCookie(new Uri(PSDATA));
context.SendingRequest += delegate (object sender, SendingRequestEventArgs e)
{
e.RequestHeaders.Clear();
e.RequestHeaders.Add("Cookie", authenticationCookie);
};
var projectQuery1 = from p in context.Projects
select p;
