一. 正常表单提交如图，可以看见输入的用户名密码等

二. 使用crypto-js.min.js进行前端加密处理

前端代码

<script type="text/javascript" src="/js/crypto-js.min.js"></script>
<script type="text/javascript">
function encrypt(str, key, iv) {//密钥16位 var key = CryptoJS.enc.Utf8.parse(key); //加密向量16位 var iv = CryptoJS.enc.Utf8.parse(iv); var encrypted = CryptoJS.AES.encrypt(str, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); return encrypted; }</script><script>layui.use('form', function () {var form = layui.form;form.render();form.on('submit(LAY-user-login-submit)', function (data) {//表单可使用var data = $(“form”).serialize();var field = data.field;var jsonstr=JSON.stringify(field);var enjsonstr=encrypt(jsonstr,'abcdefgh12345678','abcdefgh12345678');var enstr="'"+enjsonstr+"'";$.post("{:url('admin/site/login')}",{key:enstr}, function (ret) {//成功if (ret.code == 0) {layer.msg(ret.msg, { time: 1000 }, function () {window.location.href = ret.url;})} else {layer.msg(ret.msg, { time: 1000 });setTimeout(function (){window.location.reload();}, 2000);}});});});
</script>

后端使用php获取数据

$input = input("request.", '', 'trim'); 
$obj=get_object_vars(decrypt($input['key'],'abcdefgh12345678','abcdefgh12345678'));
unset($input['key']);
$input=array_merge($input,$obj);

后端解密方法如下

function decrypt($data, $key, $iv) {$decrypted = openssl_decrypt(base64_decode($data), 'AES-128-CBC', $key, true, $iv); $json_str = rtrim($decrypted, "\0");return json_decode($json_str); }
