salt - javascript behavior for '\352' decimal value -


while checking login page, found following js code

hexmd5('\232' + document.login.password.value + '\305\334\122\134\352');

so, asking \352 occupy 1 byte , hence cause overflow , yield 96 or java script interpreter promote short preserve value?

javascript doesn't have bytes, shorts, or integers*, has number type, double-precision ieee-754 number. that's not relevant code you've shown unless uses charcodeat on string corresponding code point 1 of characters in it, because you're defining code points (loosely, "characters") in string, not numbers. characters in javascript 16-bit entities, octal escape '\352' encodes character 234 decimal, readily fits within character's 16-bit range.

side note: octal escapes not part of main standard , disallowed in strict mode. they're part of non-normative annex specification. i'd recommend using hex escapes or unicode escapes rather octal ones.

* well, javascript have 32-bit integers transient thing during bit-related calculations, such performed & , | operators.

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!
