How to pass authentication header to OData Service

问题

I am following authentication method described at http://blogs.msdn.com/b/astoriateam/archive/2010/07/21/odata-and-authentication-part-6-custom-basic-authentication.aspx

I am able to consume service using ASP.NET (not a problem at all). Now I would like to create a plain HTML page and access the service using "OData Javascript Library" (datajs).

If I disable authentication and request for data, it works fine. I could not find any sample code on how to send authentication header information using "datajs" (when used with OData.Request and/or OData.Read).

Can anyone help me on this?

回答1:

If you're using basic authentication as described in the post, you can use the request parameter of OData.request to pass in the username and password.

http://datajs.codeplex.com/wikipage?title=datajs%20OData%20API#OData.request

You could write something like:

OData.request({requestUri:"...", user:"user", password:"secret"}, function (data) { ... });

Note that this will not work with cross-domain AJAX.

Hope this helps!

If you are using datajs library for service integration then you can either use above method to odata service or you can use below method as shown in example. Here I have setted headers in variable 'oHeader' and passing it using 'btoa' function which encodes credentials.

  var oHeaders = {};   
  var uName="abc";
  var pass="123";
  var requrl="{service path}";

   oHeaders['Authorization'] = "Basic " + btoa(uName +':'+ pass);

     var request = {
         headers: oHeaders,
         requestUri: requrl,
         method: "GET",
     };
     OData.request(request, function(data) {
               //  success block    
     }, function(data) {
               //  error block  
     });
