c# - Dwolla oauth access token in windows app -


i creating windows 8 metro app having trouble getting oauth2 access token. can temporary code code fine:

uri requesturi = new uri(string.format(auth_url + "?client_id={0}&response_type=code&scope={1}&client_secret={2}&redirect_uri={3}", client_id, string.join("|", scopelist.toarray()), client_secret, webauthenticationbroker.getcurrentapplicationcallbackuri().absoluteuri));         webauthenticationresult result = await webauthenticationbroker.authenticateasync(webauthenticationoptions.none, requesturi);

but when try use code permanent access token, either gives me internal server error (500) or times out. gives me 500 when don't have redirect_uri, keep in. otherwise request times out no response code:

private const string token_url = "https://www.dwolla.com/oauth/v2/token"; uri requesturi = new uri(string.format(token_url + "?client_id={0}&client_secret={1}&grant_type={2}&code={3}&redirect_uri={4}", client_id, client_secret, grant_type, code, webauthenticationbroker.getcurrentapplicationcallbackuri().absoluteuri)));         webauthenticationresult result = await webauthenticationbroker.authenticateasync(webauthenticationoptions.silentmode, requesturi);

all of strings uri escaped. don't know doing wrong.

using besides webauthenticationoptions.silentmode option shows loading browser window

also can't use oauth libraries made c# because use .netframework while windows 8 apps use .netcore, trimmed down version.

any great

the requesturi looks different between temporary code , redirect permananent access token. needs exact same thing.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
