nsstring *zipurl = @"http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location%3d%2289448%22&format=json";

3d%22*89448*%22

i need figure out how insert user entered in text box spot. have tried [nsstring stringwithformat] there many % signs doesn't work.

please let me know if need more info.

you need decode zipurl first because encoded string.

nsstring *zipurl = @"http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location%3d%2289448%22&format=json";      nsstring *decodedstring= [[nsstring stringwithformat:@"%@",zipurl] stringbyreplacingpercentescapesusingencoding:nsutf8stringencoding];     nslog(@"decodedstring : %@",decodedstring);      nsstring *mystringurl = [nsstring stringwithformat:@"http://query.yahooapis.com/v1/public/yql?q=select item weather.forecast location=%@&format=json",yourtextfield.text];

hope helps you.

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!
