后台包含pc端和手机端看看源码就知道了， 手机端获取二维码代码片段：
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case SCANNIN_GREQUEST_CODE:
if(resultCode == RESULT_OK){
Bundle bundle = data.getExtras();
//显示扫描到的内容
mTts.startSpeaking("正在处理请稍等。", mTtsListener);
webView.loadUrl("http://182.254.140.26/app/weblogin.html?id="+bundle.getString("result"));
}
break;
}
}
接下来看看WebApp处理代码（片段）
<script>
$(function () {
if (window.sessionStorage["user"] == null || window.sessionStorage["user"] == undefined) {
window.location.href = "login1.html";
} else {
$.ajax({
type: "Post",
url: "../asxsyd92/ashx/Login.ashx",
data: { type: "appcheck", u_qrcde: GetQueryString("id"), user: window.sessionStorage["user"] },
dataType: "json",
success: function (data) {
if (data.Success) {
show_msg(data.msg, "index.html");
}
else {
show_err_msg(data.msg);
}
},
error: function () {
show_err_msg('请求超时！');
}
});
}
});
function GetQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if (r != null) return unescape(r[2]); return null;
}
</script>
pc端生的处理代码：
$(function () {
$('#_qrcode').click(function () {
if ($('#zy').val() == "zh") {
$('#login_form').hide();
$("#qrcodeTable").show();
$('#zy').val('er');
