AngularJS应用中实现微信认证授权解决方案

/*-------------- 微信授权登陆 --------------*/
// 扩展 API 加载完毕后触发“plusready"事件
document.addEventListener("plusready", function() {
// 扩展API加载完毕，现在可以正常调用扩展API
plus.oauth.getServices(function(services) {
// services.length可获取当前运行环境支持授权登录认证服务数目
if (services.length > 0) {
auths = services;
} else {
alert("当前运行环境不支持授权登录认证服务！");
}
}, function(e) {
alert("获取分享服务列表失败：" + e.message + " - " + e.code);
});
}, false);
 
// 微信授权登录操作
$scope.authLogin = function(){
for(var i = 0; i < auths.length; i++){
console.log(auths[i].description);
if(auths[i].description == "微信"){
var s = auths[i];
break;
}
}
if (!s.authResult) {
console.log("微信尚未授权");
s.login(
//登录认证成功
function(e){
console.log("微信登录认证成功!");
var objuser = s.userInfo;
var uname = objuser.nickname;
console.log(objuser.nickname);
localStorage.uid = uname;
localStorage.logined = "2";
$rootScope.userinfo = {
'logined': "2",
'username': uname
};
console.log(localStorage.logined);
$scope.set_defaultaddr();
//登录后查询订单
$scope.getBillBadge();
if (sessionStorage) {
        console.log(sessionStorage.getItem("hisURL"));
        if(sessionStorage.getItem("hisURL")=='/tab/med_search')
        $rootScope.familyBox();
        $location.path(sessionStorage.getItem("hisURL"));
        }
},
//登录认证失败
function(e){
