​json reader in defined store follows:

ext.define('app.store.mylist', {     extend : 'ext.data.store',     model : 'app.model.mylist',     pagesize : 100,     proxy : {        type : 'ajax',          actionmethods : {                     create : 'post',                     read : 'post',                     update : 'post',                     destroy : 'post'         },         root : 'results',         url : 'aaa.htm',         reader : {                     type : 'json',                     root : 'results',                     totalproperty: 'totalcount',                     extraproperty: 'abcd'     },     simplesortmode : true      } });

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!
