58同城的登录是使用的Post提交方法，提交原文章是这样的

里面是没有密码是，而是使用JS进行的加密p1,p2就是加密后的数据，
那这个是使用一个JS文件来加密的，JS文件如下
function getm32str(str, timesign) { return hex_md5(hex_md5(str) + timesign); } function getm16str(str, timesign) { return hex_md5(str + timesign); } function hex_md5(s) { return binl2hex(core_md5(str2binl(s), s.length * 8)); } function str2binl(str) { var bin = Array(); var mask = (1 << 8) - 1; for (var i = 0; i < str.length * 8; i += 8) { bin[i >> 5] |= (str.charCodeAt(i / 8) & mask) << (i % 32); } return bin; } function md5_cmn(q, a, b, x, s, t) { return safe_add(bit_rol(safe_add(safe_add(a, q), safe_add(x, t)), s), b); } function md5_ff(a, b, c, d, x, s, t) { return md5_cmn((b & c) | ((~b) & d), a, b, x, s, t); } function md5_gg(a, b, c, d, x, s, t) { return md5_cmn((b & d) | (c & (~d)), a, b, x, s, t); } function md5_hh(a, b, c, d, x, s, t) { return md5_cmn(b ^ c ^ d, a, b, x, s, t) } function md5_ii(a, b, c, d, x, s, t) { return md5_cmn(c ^ (b | (~d)), a, b, x, s, t); } function core_md5(x, len) { x[len >> 5] |= 0x80 << ((len) % 32); x[(((len + 64) >>> 9) << 4) + 14] = len; var a = 1732584193; var b = -271733879; var c = -1732584194; var d = 271733878; for (var i = 0; i < x.length; i += 16) { var olda = a; var oldb = b; var oldc = c; var oldd = d; a = md5_ff(a, b, c, d, x[i + 0], 7, -680876936); d = md5_ff(d, a, b, c, x[i + 1], 12, -389564586); c = md5_ff(c, d, a, b, x[i + 2], 17, 606105819); b = md5_ff(b, c, d, a, x[i + 3], 22, -1044525330); a = md5_ff(a, b, c, d, x[i + 4], 7, -176418897); d = md5_ff(d, a, b, c, x[i + 5], 12, 1200080426); c = md5_ff(c, d, a, b, x[i + 6], 17, -1473231341); b = md5_ff(b, c, d, a, x[i + 7], 22, -45705983); a = md5_ff(a, b, c, d, x[i + 8], 7, 1770035416); d = md5_ff(d, a, b, c, x[i + 9], 12, -1958414417); c = md5_ff(c, d, a, b, x[i + 10], 17, -42063); b = md5_ff(b, c, d, a, x[i + 11], 22, -1990404162); a = md5_ff(a, b, c, d, x[i + 12], 7, 1804603682); d = md5_ff(d, a, b, c, x[i + 13], 12, -40341101); c = md5_ff(c, d, a, b, x[i + 14], 17, -1502002290); b = md5_ff(b, c, d, a, x[i + 15], 22, 1236535329); a = md5_gg(a, b, c, d, x[i + 1], 5, -165796510); d = md5_gg(d, a, b, c, x[i + 6], 9, -1069501632); c = md5_gg(c, d, a, b, x[i + 11], 14, 643717713); b = md5_gg(b, c, d, a, x[i + 0], 20, -373897302); a = md5_gg(a, b, c, d, x[i + 5], 5, -701558691); d = md5_gg(d, a, b, c, x[i + 10], 9, 38016083); c = md5_gg(c, d, a, b, x[i + 15], 14, -660478335); b = md5_gg(b, c, d, a, x[i + 4], 20, -405537848); a = md5_gg(a, b, c, d, x[i + 9], 5, 568446438); d = md5_gg(d, a, b, c, x[i + 14], 9, -1019803690); c = md5_gg(c, d, a, b, x[i + 3], 14, -187363961); b = md5_gg(b, c, d, a, x[i + 8], 20, 1163531501); a = md5_gg(a, b, c, d, x[i + 13], 5, -1444681467); d = md5_gg(d, a, b, c, x[i + 2], 9, -51403784); c = md5_gg(c, d, a, b, x[i + 7], 14, 1735328473); b = md5_gg(b, c, d, a, x[i + 12], 20, -1926607734); a = md5_hh(a, b, c, d, x[i + 5], 4, -378558); d = md5_hh(d, a, b, c, x[i + 8], 11, -2022574463); c = md5_hh(c, d, a, b, x[i + 11], 16, 1839030562); b = md5_hh(b, c, d, a, x[i + 14], 23, -35309556); a = md5_hh(a, b, c, d, x[i + 1], 4, -1530992060); d = md5_hh(d, a, b, c, x[i + 4], 11, 1272893353); c = md5_hh(c, d, a, b, x[i + 7], 16, -155497632); b = md5_hh(b, c, d, a, x[i + 10], 23, -1094730640); a = md5_hh(a, b, c, d, x[i + 13], 4, 681279174); d = md5_hh(d, a, b, c, x[i + 0], 11, -358537222); c = md5_hh(c, d, a, b, x[i + 3], 16, -722521979); b = md5_hh(b, c, d, a, x[i + 6], 23, 76029189); a = md5_hh(a, b, c, d, x[i + 9], 4, -640364487); d = md5_hh(d, a, b, c, x[i + 12], 11, -421815835); c = md5_hh(c, d, a, b, x[i + 15], 16, 530742520); b = md5_hh(b, c, d, a, x[i + 2], 23, -995338651); a = md5_ii(a, b, c, d, x[i + 0], 6, -198630844); d = md5_ii(d, a, b, c, x[i + 7], 10, 1126891415); c = md5_ii(c, d, a, b, x[i + 14], 15, -1416354905); b = md5_ii(b, c, d, a, x[i + 5], 21, -57434055); a = md5_ii(a, b, c, d, x[i + 12], 6, 1700485571); d = md5_ii(d, a, b, c, x[i + 3], 10, -1894986606); c = md5_ii(c, d, a, b, x[i + 10], 15, -1051523); b = md5_ii(b, c, d, a, x[i + 1], 21, -2054922799); a = md5_ii(a, b, c, d, x[i + 8], 6, 1873313359); d = md5_ii(d, a, b, c, x[i + 15], 10, -30611744); c = md5_ii(c, d, a, b, x[i + 6], 15, -1560198380); b = md5_ii(b, c, d, a, x[i + 13], 21, 1309151649); a = md5_ii(a, b, c, d, x[i + 4], 6, -145523070); d = md5_ii(d, a, b, c, x[i + 11], 10, -1120210379); c = md5_ii(c, d, a, b, x[i + 2], 15, 718787259); b = md5_ii(b, c, d, a, x[i + 9], 21, -343485551); a = safe_add(a, olda); b = safe_add(b, oldb); c = safe_add(c, oldc); d = safe_add(d, oldd) } return Array(a, b, c, d); } function bit_rol(num, cnt) { return (num << cnt) | (num >>> (32 - cnt)); } function safe_add(x, y) { var lsw = (x & 0xFFFF) + (y & 0xFFFF); var msw = (x >> 16) + (y >> 16) + (lsw >> 16); return (msw << 16) | (lsw & 0xFFFF) } function binl2hex(binarray) { var hexcase = 0; var hex_tab = hexcase ?

我们先在自己的项目里添加两个引用看下图
然后看我的代码吧

//得到P2 string p2 = ww.ToString(); HttpItem item = new HttpItem() { URL = "https://passport.58.com/dounionlogin", Encoding = "utf-8", Method = "POST", Postdata = "isweak=1&path=http%3A%2F%2Fxa.58.com%2F%3Fpts%3D1356513306818&" + "p1=" + p1 + "&" + "p2=" + p2 + "&" + "timesign=" + time + "&ptk=e3741580635e4fd8aab83345a3433853&cd=8739&username=sufei1125&password=password" }; HttpHelper http = new HttpHelper(); string html = http.GetHtml(item); if (string.IsNullOrEmpty(item.Cookie)) { //登录失败 richTextBox1.Text = "登录失败"; } else { //成功登录 richTextBox1.Text = "登录成功"; } } }}这样就行了，
具体的大家可以下载例子看看，合作的是我的HttpHelper类
