[twitter-dev] Re: C# + OAuth + account/update_profile_image = 500 Internal Server Error
You can use TwitterVB which covers nearly the complete API in .NET (OAuth included). U find it on codeplex http://twittervb.codeplex.com/ Cheers, Thomas Nicholas Granado schrieb: Simon, You would sign the request with all of the usual oauth param suspects. If I recall correctly this endpoint has no other params other than the 'image' param in the multi-part post body whose value would be the bytes of the image file. Typically I've only seen the post params passed into the oauth signing rigmarole when the post body is urlencoded. I hope this helps, this whole OAuth thing can be very confusing at first glance. If you are in C# I have my own lib for twitter basic auth/oauth that I've baked up, if you like I could pass you the bits.

In you opinion, how do I then sign the request? Do I use all the usual for the signaturebase... ie postmethodurlnonceetc etc or just postmethodurl as David suggested? I trust that the image data does not come into the signing process, and that I still can post the data using iso-8859-1 encoding as I would normally do for uploading files? If you have these answers, then I should be able to nail this for our .net case.Oauth's been working great for us until this hitch...

I've tried all sorts... dropping the off the end different encodings... What encoding did you use to encode your image, and then to post the request? Does it still work for you... or did this get broken when Twitter 'fixed' their Oauth implementation? Can anyone else advise if they have got this working and where I might be going wrong?

First of all, unbelievably, the 500 Internal Server Error was being caused by an extra carriage return between my last HTTP header and the first multipart boundary. Seriously. I had two blank lines in there instead of one. Removed the extra carriage return, and my 500 vanished, being replaced by a more reasonable (401) Unauthorized - Incorrect signature error. Secondly, the OAuth documentation seems a bit shaky when it comes to multipart/form-data POSTs. But basically, you do NOT use any of the POST parameters when creating your signature. And this includes all of the OAuth-specific parameters like oauth_consumer_key, oauth_signature_method, etc. Bit of a security hole imho, OAuth implements all this complexity to avoid man-in-the-middle or replay attacks, and as soon as you do a multipart POST it's all negated. So, my signature base was literally:
[twitter-dev] Re: How to check if user is followed?
I only can talk for .NET - A Dictionary(of Long, Boolean) with 5000 Id's needs around 500 Ticks If I request the Method .ContainsKey. I don't think that an API Request with parsing xml can be faster. Additional you nail the server with unneeded requests which are expensive (rate limits) too I don't know your Applicaton but you'll handle all accounts at the same time? Normaly if an user authenticates the first calls could be to request the ID Lists and store them during this users sessiontime. If a user leaves you can free this memory.

[twitter-dev] Re: Return number of pages (or number of friends/followers) on first call with cursor
the Number of ID's is the number of followers you also can call http://apiwiki.twitter.com/Twitter-REST-API-Method%3A-users%C2%A0show first. Within the result you have followers_count1031/followers_count friends_count293/friends_count however - you have to do an additional API call if you don't trust the pagewise calls Jesse Stay schrieb: Thomas, I don't see where it gives you the expected number of users. Originally I thought Alex said that was going to be part of it, but not seeing it in the docs. I only see ids, next_cursor, and previous_cursor.

Jesse Stay schrieb: I was wondering if it might be possible to include, at least in the first page, but if it's easier it could be on all pages, either a total expected number of followers/friends, or a total expected number of returned pages when the cursor parameter is provided for friends/ids and followers/ids? I'm assuming since you're moving to the cursor-based approach you ought to be able to accurately count this now since it's a snapshot of the data at that time. The reason I think that would be useful is that occasionally Twitter goes down or introduces code that could break this. This would enable us to be absolutely sure we've hit the end of the entire set. I guess another approach could also be to just list the last expected cursor ID in the set so we can be looking for that. Thanks, Jesse signature.asc Description: OpenPGP digital signature
[twitter-dev] Social Graph Methods followers/names ?
Hi All, would it be possible to get an additional API function which delivers the screennames instead of ID's? The reason is, I work on a Client App in .NET On Startup I load the followers, friends and blocked ID's. I use this to show the status then in my application and enable/ disable the menus with follow/ unfollw DM and so on. So I save expensive API calls (follow someone which I already follow) which ends in API Errors. So far so good. Now I try to implement the search API. This delivers me ATOM XML back. I Try to fill my status object and included User object with the less informations in delivered ATOM to show it in the same Quality like a User Timeline. Unfortunately the only thing I have in ATOM result is the screenname combined with username in one tag. No Problem I resolve that with RegEx. What urgently is missed is the user ID to compare it with the followers and friend list of ID's Now 2 solutions are possible: 1) adding the userID in the search results 2) offer an API call within social graph methods which delivers screennames In case of 2) I could use the unique screenname as Key. This would be a disadvantage because of searchroutines work always slower on string. Better soulution would be to delivers the userID within the searchresults. Is there any way to realize this? I do not think that I'm the only one ho miss this. Best regards, Thomas

You have to register your App @ Twitter and user OAuth.

[twitter-dev] Re: Social Graph Methods followers/names ?
I would see this as second coice - userID in searchresults would be the better choice because a numeric comparing is in each case faster then string comparing Best would be to get both. From side of server (Database request) both things should be not to tricky to make. cheers, Thomas Nelu Lazar schrieb: I subscribe to this request.
