I read a piece code from my friend but I don't understand why it can run. Here is filter of Grails.
def filters = {
protectResource(uri: "/api/**", uriExclude: "/api/user/*") {
before = {
....
springSecurityService.reauthenticate(authentication.name)
....
}
}
It's like save user session for use later. And here is a piece code for "get user session" by webservice.
#GET
Response getProfile() {
User user = springSecurityService.currentUser
...
}
I think session saved by cookieID between server and browser, if you work by HttpsURLConnection and something like Apache's HttpComponent, you can't save cookieID in that.
I searched somewhere but I'm still confuse about how to save session and security about that phase.
Have any idea about that?
Thanks in advance!

Identity server is implemented and working well. Google login is working and is returning several claims including email.
Facebook login is working, and my app is live and requests email permissions when a new user logs in.
The problem is that I can't get the email back from the oauth endpoint and I can't seem to find the access_token to manually request user information. All I have is a "code" returned from the facebook login endpoint.
Here's the IdentityServer setup.
var fb = new FacebookAuthenticationOptions
{
AuthenticationType = "Facebook",
SignInAsAuthenticationType = signInAsType,
AppId = ConfigurationManager.AppSettings["Facebook:AppId"],
AppSecret = ConfigurationManager.AppSettings["Facebook:AppSecret"]
};
fb.Scope.Add("email");
app.UseFacebookAuthentication(fb);
Then of course I've customized the AuthenticateLocalAsync method, but the claims I'm receiving only include name. No email claim.
Digging through the source code for identity server, I realized that there are some claims things happening to transform facebook claims, so I extended that class to debug into it and see if it was stripping out any claims, which it's not.
I also watched the http calls with fiddler, and I only see the following (apologies as code formatting doesn't work very good on urls. I tried to format the querystring params one their own lines but it didn't take)
(facebook.com)
/dialog/oauth

&state=xxx
I saw the code parameter on that last call and thought that maybe I could use the code there to get the access_token from the facebook API https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow
However when I tried that I get a message from the API telling me the code has already been used.
I also tried to change the UserInformationEndpoint to the FacebookAuthenticationOptions to force it to ask for the email by appending ?fields=email to the end of the default endpoint location, but that causes identity server to spit out the error "There was an error logging into the external provider. The error message is: access_denied".
I might be able to fix this all if I can change the middleware to send the request with response_type=id_token but I can't figure out how to do that or how to extract that access token when it gets returned in the first place to be able to use the Facebook C# sdk.
So I guess any help or direction at all would be awesome. I've spent countless hours researching and trying to solve the problem. All I need to do is get the email address of the logged-in user via IdentityServer3. Doesn't sound so hard and yet I'm stuck.
I finally figured this out. The answer has something to do with Mitra's comments although neither of those answers quite seemed to fit the bill, so I'm putting another one here. First, you need to request the access_token, not code (authorization code) from Facebook's Authentication endpoint. To do that, set it up like this
var fb = new FacebookAuthenticationOptions
{
AuthenticationType = "Facebook",
SignInAsAuthenticationType = signInAsType,
AppId = ConfigurationManager.AppSettings["Facebook:AppId"],
AppSecret = ConfigurationManager.AppSettings["Facebook:AppSecret"],
Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = (context) =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("urn:facebook:access_token", context.AccessToken, ClaimValueTypes.String, "Facebook"));
return Task.FromResult(0);
}
}
};
fb.Scope.Add("email");
app.UseFacebookAuthentication(fb);
Then, you need to catch the response once it's logged in. I'm using the following file from the IdentityServer3 Samples Repository, which overrides (read, provides functionality) for the methods necessary to log a user in from external sites. From this response, I'm using the C# Facebook SDK with the newly returned access_token claim in the ExternalAuthenticationContext to request the fields I need and add them to the list of claims. Then I can use that information to create/log in the user.
public override async Task AuthenticateExternalAsync(ExternalAuthenticationContext ctx)
{
var externalUser = ctx.ExternalIdentity;
var claimsList = ctx.ExternalIdentity.Claims.ToList();
if (externalUser.Provider == "Facebook")
{
var extraClaims = GetAdditionalFacebookClaims(externalUser.Claims.First(claim => claim.Type == "urn:facebook:access_token"));
claimsList.Add(new Claim("email", extraClaims.First(k => k.Key == "email").Value.ToString()));
claimsList.Add(new Claim("given_name", extraClaims.First(k => k.Key == "first_name").Value.ToString()));
claimsList.Add(new Claim("family_name", extraClaims.First(k => k.Key == "last_name").Value.ToString()));
}
if (externalUser == null)
{
throw new ArgumentNullException("externalUser");
}
var user = await userManager.FindAsync(new Microsoft.AspNet.Identity.UserLoginInfo(externalUser.Provider, externalUser.ProviderId));
if (user == null)
{
ctx.AuthenticateResult = await ProcessNewExternalAccountAsync(externalUser.Provider, externalUser.ProviderId, claimsList);
}
else
{
ctx.AuthenticateResult = await ProcessExistingExternalAccountAsync(user.Id, externalUser.Provider, externalUser.ProviderId, claimsList);
}
}
And that's it! If you have any suggestions for simplifying this process, please let me know. I was going to modify this code to do perform the call to the API from FacebookAuthenticationOptions, but the Events property no longer exists apparently.
Edit: the GetAdditionalFacebookClaims method is simply a method that creates a new FacebookClient given the access token that was pulled out and queries the Facebook API for the other user claims you need. For example, my method looks like this:
protected static JsonObject GetAdditionalFacebookClaims(Claim accessToken)
{
var fb = new FacebookClient(accessToken.Value);
return fb.Get("me", new {fields = new[] {"email", "first_name", "last_name"}}) as JsonObject;
}
I am trying my first web app service using Azure services. I've created it in VS, and it works locally. All it does it return a string that says "hello user" is JSON.
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1
{
// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json)
// To create an operation that returns XML,
// add [WebGet(ResponseFormat=WebMessageFormat.Xml)],
// and include the following line in the operation body:
// WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";
[OperationContract]
[WebGet(UriTemplate = "/DoWork")]
public string DoWork()
{
// Add your operation implementation here
return "hello user";
}
// Add more operations here and mark them with [OperationContract]
}
}
Problem is when I publish it, says successful. I can see it running on portal.
When I goto published site I get the standard THIS WEB APP HAS BEEN SUCCESSFULLY CREATED, but... when I add the /DoWork to the URL I get HTTP error 404.
I know I must be missing something simple...
any ideas?
you're missing the name of the service. In your case would be something like:
http://engineappservicev001.azurewebsites.net/something.svc/dowork

I'm using Django 1.6.
I want to set session id.
When I use web browser, I can watch "sessionid" logs.
But, when I used other application like Unity3d,
I can't watch "sessionid" logs.
Could you tell me how to get a session id?
I've create the view
But, I'm accessing application like unity
it returns.
def get_token(request):
# request_cookies = OrderedDict(request.COOKIES)
context = {}
context.update(csrf(request))
context['csrf_token'] = force_text(context['csrf_token'])
session_key = request.session.session_key
context['sessionid'] = session_key
return HttpResponse(json.dumps(context), content_type="application/json")
But, session id is null. however web broweser is okey.
jsonText: {"csrf_token": "xma9Dtmv46va5uomZiZ9dcjjfCB9E2Gw", "sessionid": null}
Sessions are set using cookies. Cookies are implemented by the vast majority of browser but not by other http clients.
Since you mention Unity, I guess what you are building with Django is an api. I suggest you take a look at http://www.django-rest-framework.org/api-guide/authentication/#tokenauthentication as an alternative to relying on cookies.
I have an application using ember-couchdb-kit to interface with a CouchDB instance. I am having difficulty accessing the server after requiring authentication.
I tried cookie authentication and the cookie gets set in the browser, but it isn't sent to the database for subsequent requests according to the network dialog in both Chrome and Firefox.
I don't understand why this is happening, but in the pursuit of getting the application working, I wanted to try HTTP auth.
My document adapter is just:
App.Host = 'http://localhost:5984'
App.ApplicationAdapter = EmberCouchDBKit.DocumentAdapter.extend( { db: 'wells', host: App.Host } )
I want to add the username and password to the URL, so after the user enters them, I run:
EmberCouchDBKit.DocumentAdapter.reopen( {
host: ( function() {
var parts = App.Host.split( '://' )
return "%#://%#:%##%#".fmt( parts[0], $('#username').val(), $('#password').val(), parts[1] )
} )()
} )
The URL for subsequent requests doesn't change though. What do I need to do?
The adapter isn't recreated each time it's used, and reopen only applies to newly created instanes. As such you'll need to redefine it on the already existing adapter instance. Inside a route/controller you could do it like so:
var adapter = this.store.adapterFor('application');
adapter.set('host', 'foobar');
I am trying to Post and get a cookie. I am a newbie and this is a learning project for me. My impression is that if you use 'set-cookie' one should be able to see an additional 'set-cookie' in the .toSource. (I am trying to accomplish this on Google Apps Site if that makes a difference.) Am I missing something? Here is my code:
function setGetCookies() {
var payload = {'set-cookie' : 'test'};
var opt2 = {'headers':payload, "method":"post"};
UrlFetchApp.fetch("https://sites.google.com/a/example.com/blacksmith", opt2);
var response = UrlFetchApp.fetch("https://sites.google.com/a/example.com/blacksmith")
var openId = response.getAllHeaders().toSource();
Logger.log(openId)
var AllHeaders = response.getAllHeaders();
for (var prop in AllHeaders) {
if (prop.toLowerCase() == "set-cookie") {
// if there's only one cookie, convert it into an array:
var myArray = [];
if ( Array.isArray(AllHeaders[prop]) ) {
myArray=AllHeaders[prop];
} else {
myArray[0]=AllHeaders[prop];
}
// now process the cookies
myArray.forEach(function(cookie) {
Logger.log(cookie);
});
break;
}
}
}
Thanks in advance! I referenced this to develop the code: Cookie handling in Google Apps Script - How to send cookies in header?
Open to any advice.
When you aren't logged in Google Sites won't set any cookies in the response. UrlFetchApp doesn't pass along your Google cookies, so it will behave as if you are logged out.
First the cookie you want to send whose name is 'test' does not have a value. You should send 'test=somevalue'.
Second I am wondering if you are trying to send the cookie to the googlesite server and ask it to reply with the same cookie you previously sent... ?
I am thinking you are trying to act as a HTTP server beside you are a HTTP client.
As a HTTP client your role is only to send back any cookies that the HTTP server have previously sent to you (respecting the domain, expiration... params).
