Im using dotCMIS and would like to do a simple connect to my SP2010 server. Im trying to do this with C# like here http://chemistry.apache.org/dotnet/getting-started-with-dotcmis.html in the first part
So I have something like this:
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters[SessionParameter.BindingType] = BindingType.AtomPub;
parameters[SessionParameter.AtomPubUrl] = "http://mysharepoint";
parameters[SessionParameter.User] = "SPAdmin";
parameters[SessionParameter.Password] = "1234sharepoint";
SessionFactory factory = SessionFactory.NewInstance();
ISession session = factory.GetRepositories(parameters)[0].CreateSession(); //exception unathorized
But I get always the exception: DotCMIS.Expcetions.CmisRunterimException: Unathorised
Any ideas? Via browser I can login to the site with the same user/pass, so thats might be not the problem. At first I tought its because of the NTLM problem (https://issues.apache.org/jira/browse/CMIS-531) but even if Im using parameters[SessionParameter.AuthenticationProviderClass] = "DotCMIS.Binding.NtlmAuthenticationProvider"; its the same exception. And well... this exception is not really helping me. I wish I could get more information - maybe there is a better way? What else could I try? Thank you!
PS: And yes, before I started with dotCMIS I did install and configure the MS CMIS connector: http://technet.microsoft.com/en-us/library/ff934619.aspx
Your AtomPubUrl looks suspicious. I can't tell if that's a placeholder you've added to mask the real URL or if that's the actual URL you are using. If it is the actual URL it looks like it is missing the path to the AtomPub service document. To tell if that's the case, you should be able to invoke the URL, log in, and get a bunch of XML back, which is the CMIS service descriptor. If instead you are getting a user-facing page full of HTML, you are using the wrong URL.
For example, in Alfresco, users log in to /share, but the AtomPub binding is at /alfresco/cmisatom.
Yes the AtomPubUrl was wrong.
For sharepoint its not enough to post the default sp url (http://mysharepoint) or the url to the cmis lib (http://mysharepoint/cmis)
I need to point to the repository id, somehow the sp endpoint for CMIS is:
http://mysharepoint/_vti_bin/<myLib4CMIS>/<repID>?getRepositoryInfo
http://technet.microsoft.com/en-us/library/ff934619.aspx
Somehow it was confusing, but its working :) dotCMIS is really nice.

I have the following error when using DropNet library to make connection to DropBox.
Trying to implement it for my CMS and also for my knowledge :)
trying the current documentation of DropNet.
Source:https://github.com/DropNet/DropNet
Current code:
var _client = new DropNetClient(Core.DropBoxAPI, Core.DropBoxKeySecret);
UserLogin login = _client.GetToken();
_client.UserLogin = login;
String Url = _client.BuildAuthorizeUrl();
Produces:
Received Response [Unauthorized] : Expected to see [OK]. The HTTP
response was [{"error": "Unauthorized"}].
Exception: DropNet.Exceptions.DropboxRestException: Received Response
[Unauthorized] : Expected to see [OK]. The HTTP response was
[{"error": "Unauthorized"}].
I want to let the user connect to the Url returned by _client.BuildAuthorizeUrl(); but it even won't let me get to url
and i also have a Key and Secret generated from DropBox.com
if i try to set the method _client.BuildAuthorizeUrl(); as first statement it gives also an error on the DropBox page itselfs.
I tried to find an another post on Stackoverflow but i didn't find any solution so fare.
Its still using the basics of the documentation and it goes wrong.
If you have any ideas that would be nice.
Thanks for the advices.
I was filling the secret the same as the APP key.
I am trying to access data remotely from sharepoint 2010 site using client object model. For some restrictions I am not able to use CAML query even if I use I am not able to filter for proper audiences based on user login (if you can help me regarding the CAML query is also fine :: i do not know how to get current user audience name and all audiences using CAML/client object model. This code sits on the mobile site and calling the share point site as shown in my code). This following code works good but not able to get the content from the webpart. Can someone help regarding this.
using (ClientContext ctx = new ClientContext("https://mysite.com/Pages/Default.aspx"))
{
ctx.ExecutingWebRequest += new EventHandler<WebRequestEventArgs> (clientContext_ExecutingWebRequest);
File home=ctx.Web.GetFileByServerRelativeUrl("/Student/Pages/default.aspx");
//get the web part manager
Microsoft.SharePoint.Client.WebParts.LimitedWebPartManager wpm = home.GetLimitedWebPartManager(Microsoft.SharePoint.Client.WebParts.PersonalizationScope.Shared);
IEnumerable<Microsoft.SharePoint.Client.WebParts.WebPartDefinition> wpds = null;
//create the LINQ query to get the web parts from
//the web part definition collection
wpds = ctx.LoadQuery(wpm.WebParts.Include(wp => wp.Id,wp => wp.WebPart));
//load the list of web parts
ctx.ExecuteQuery();
//enumerate the results
foreach (Microsoft.SharePoint.Client.WebParts.WebPartDefinition wpd in wpds)
{
string title= wpd.WebPart.Title;
Microsoft.SharePoint.Client.WebParts.WebPart wpart = wpd.WebPart;
????? How to render and receive the data (looking for the same data When you browse the site with the browser)
}
Code continues...
I am also struggling with this issue. It really looks like this is not possible with client object model. Actually i've asked it to some SharePoint staff member at Build Conference 2012.
But, with the SharePoint Designer it's actually possible to download the wanted WebPart. Fiddler may come handy to track down which service will deliver you the bits.
Take a look at this post here on SharePoint StackExchange
Unfortunately the post will not give you any concrete way to solve it.
Wish you good luck!
I'm writhing a web application (ASP.Net MVC, C#) that require the user to provide urls to RSS or Atom Feed that I then read with the following code :
var xmlRdr = XmlReader.Create(urlProvidedByUserAsString);
var syndicFeed = SyndicationFeed.Load(xmlRdr);
While debugging my application I accidentally passed /something/like/this as an url and I got an exception telling me that C:\something\like\this can't be opened.
It looks like a user could provide a local path and my application would try to read it.
How can I make this code safe? It probably is not sufficient to check for https:// or http:// at the begining of the url, since the user could still enter something like http://localhost/blah. Is there any other way, maybe with the uri class to check if an url is pointing to the web?
Edit: I think I also need to prevent the user from entering adresses that would point to other machines on my network like this example: http://192.168.0.6/ or http://AnotherMachineName/
Try:
new Uri(#"http://stackoverflow.com").IsLoopback
new Uri(#"http://localhost/").IsLoopback
new Uri(#"c:\windows\").IsLoopback
I'm trying to put together a small app that will allow me to create events in Facebook. I've already got my Facebook app set up and have successfully tested a post to my feed through the application using the code below.
wc.UploadString("https://graph.facebook.com/me/feed", "access_token=" + AccessToken + "&message=" + Message);
When I try to take things to the next step, I've just hit a brick wall.
The code that I've written is here:
JavaScriptSerializer ser = new JavaScriptSerializer();
wc.UploadString("https://graph.facebook.com/me/events?" + "access_token=" + AccessToken, ser.Serialize(rawevent));
rawevent is a small object I wrote that puts together the elements of an event so I can pass it around my application.
I'm using a similar method using ser.Deserialize to parse the user data coming back from Facebook, so I believe this should work the other way too.
Setting the above code aside for a moment, I also have tried simply putting plain text in there in various formats and with differing levels of parameters, and nothing seems to work.
Is there something wrong with the way I'm approaching this? I've read over everything I could get my hands on, and very few of the samples out there that I could find deal with creating events, and when they do, they're not in C#.
I would appreciate any help on this. If you even just have a clean copy of JSON code that I can look at and see where mine should be tweaked I would appreciate it.
I have included a copy of what the ser.Serialize(rawevent) call produces below:
{"name":"Dev party!","start_time":"1308360696.86778","end_time":"1310952696.86778","location":"my house!"}
EDIT:
thanks to bronsoja below, I used the code below to successfully post an event to Facebook!
System.Collections.Specialized.NameValueCollection nvctest = new System.Collections.Specialized.NameValueCollection();
nvctest.Add("name", "test");
nvctest.Add("start_time", "1272718027");
nvctest.Add("end_time", "1272718027");
nvctest.Add("location", "myhouse");
wc.UploadValues("https://graph.facebook.com/me/events?" + "access_token=" + AccessToken, nvctest);
All the posting examples in the graph api examples in FB docs show using curl -F, which indicates values be POSTed as normal form data. Just key value pair like you did in your first example.
The error is likely due to sending JSON. If you are using WebClient you may be able to simply create a NameValueCollection with your data and use WebClient.UploadValues to send the request.
I've recently found that Facebook returns (#100) Invalid parameter when we are trying to post data when there is already a record on file with the same name. So for example, if you are creating a FriendList via the API, and the name is "foo", submitting another identical request for the same name will immediately return that error.
In testing events you probably deleted the "Dev party!" event after each test, or maybe changing the time since you don't want two events to collide. But I'm wondering if you duplicated your wc.UploadValues(...) statement just as a test if you would see that error again. You're either deleting your 'test' event or maybe changing names and didn't notice that two events with the same name might return the error.
What's really bad here is that the error comes back as a OAuthException, which seems very wrong. This isn't a matter of authentication or authorization, it's purely a data issue.
Facebook Engineers, if I'm right about how this works, it's a bug to return this error under these conditions, and this forum has many examples of related confusion. Please return more appropriate errors.
This is a follow-up to Choosing a Connection String based on kind of request for which I got no answer and what I thought worked doesn't.
I have a webservice that needs to choose a specific connection string based on the user calling it from a browser or from a client application.
I tried:
HttpContext.Current != null? ConnectionStrings["Website"].ConnectionString : ConnectionStrings["Client"].ConnectionString
but realized that at some point even if I'm using the client application, there is some HttpContext (if someone can explain why it'd be great) but the Browser field under Request is "Unknown". So, then I tried:
if ( HttpContext.Current != null )
{
if ( HttpContext.Current.Request.Browser != "Unknown" )
{
//browser connection string here
}
else
//client app connection string here
}
else
//client app connection string here
This worked wonders when debugging, but on testing environment it still points to Browser connection string even when calling from the client app, as if at some point the Browser isn't "Unknown" ...
Is there a MUCH easier/simpler way to do this? The way I'm doing it seems really ugly.
I'm quite desperate at the moment as I have no idea why this is happening..
Rather than detecting and switching on the browser type, consider these two suggestions:
Add Custom Request Headers
In your various callers, define a new custom header in your Http request.
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("CallerType", "ClientApp"); // "Browser", etc.
Then you know exactly and reliably what type of client is calling. This would be hard to get wrong, and couldn't be spoofed/mistaken.
Include The Caller Type in the QueryString
myService.asmx?BrowserType=1
Add a simple new querystring parameter to your .asmx webmethod. This will work just the same in a controlled environment, but if other users/developers get it wrong, or malform the expected values, you'd have to take other measures to correct/handle.
Both allow you to easily determine the connString on the incoming value. Perhaps the absense of a modifier/header, you could assume a default. Your sample question has 2 basic outcomes, and either suggested solution will be easy to extend (browser, client app, iPhone, whathaveyou).
