You post JSON like this    ajax url        data   JSON stringify myJSObject       contentType    application json       type    POST             if you pass an object as settings data jQuery will convert it to query parameters and by default send with the data type application x-www-form-urlencoded  charset UTF-8  probably not what you want

In case you are sending this post request to a cross domain  you should check out this link   https   stackoverflow com a 1320708 969984  Your server is not accepting the cross site post request  So the server configuration needs to be changed to allow cross site requests
