https://developers.google.com/identity/sign-in/web/sign-in在Google角色网站上获得了Google登录.
我看到一些奇怪的行为.登录按钮有时显示但不总是.刷新页面时,仅刷新1到5,该按钮出现. 我在Chrome和Safari中尝试过,并且都有相同的行为. 码: 的index.html <script src="https://apis.google.com/js/platform.js" async defer></script> <meta name="google-signin-client_id" content="my_client_id"> 的login.html <div class="g-signin2" data-onsuccess="onSignIn"></div> login.js angular.module('app').controller('LoginCtrl',function($scope) { window.onSignIn = function(googleUser) { // Get some info } });
我的猜测是,platform.js脚本等待DOM就绪事件,然后用“g-signin2”类查找你的div.虽然在Angularjs的事情有所不同.它有时工作的原因是因为有时你的div已经被角色渲染了,有时候还没有在Dom-ready事件之前呈现.
有 documentation如何获得与您自己的javascript相同的结果. 我做了一个例子,跟随你的路由. <!doctype html> <html lang="en" ng-app="app"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <div ng-view></div> <script src="https://apis.google.com/js/platform.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script> <script src="https://code.angularjs.org/1.4.6/angular-route.min.js"></script> <script> angular.module('app',['ngRoute']) .config(['$routeProvider',function($routeProvider){ $routeProvider .when('/log-in',{ template: '<button ng-click="logInCtrl.onLogInButtonClick()">Log In</button>',controller: 'LogInController',controllerAs: 'logInCtrl' }).otherwise({ redirectTo:'/log-in' }); }]) .controller('LogInController',function(){ var self = this; //to be able to reference to it in a callback,you could use $scope instead gapi.load('auth2',function() {//load in the auth2 api's,without it gapi.auth2 will be undefined gapi.auth2.init( { client_id: 'CLIENT_ID.apps.googleusercontent.com' } ); var GoogleAuth = gapi.auth2.getAuthInstance();//get's a GoogleAuth instance with your client-id,needs to be called after gapi.auth2.init self.onLogInButtonClick=function(){//add a function to the controller so ng-click can bind to it GoogleAuth.signIn().then(function(response){//request to sign in console.log(response); }); }; }); }); </script> </body> </html> 或作为指示: <!doctype html> <html lang="en" ng-app="app" ng-controller="MainController"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <google-sign-in-button on-sign-in="onSignIn(response)" g-client-id="CLIENTID.apps.googleusercontent.com"></google-sign-in-button> <script src="https://apis.google.com/js/platform.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script> <script> angular.module('app',[]) .controller('MainController',['$scope',function ($scope) { $scope.onSignIn=function(response){ console.log(response); } }]) .directive('googleSignInButton',function(){ return { scope:{ gClientId:'@',callback: '&onSignIn' },template: '<button ng-click="onSignInButtonClick()">Sign in</button>',controller: ['$scope','$attrs',function($scope,$attrs){ gapi.load('auth2',without it gapi.auth2 will be undefined gapi.auth2.init( { client_id: $attrs.gClientId } ); var GoogleAuth = gapi.auth2.getAuthInstance();//get's a GoogleAuth instance with your client-id,needs to be called after gapi.auth2.init $scope.onSignInButtonClick=function(){//add a function to the controller so ng-click can bind to it GoogleAuth.signIn().then(function(response){//request to sign in $scope.callback({response:response}); }); }; }); }] }; }); </script> </body> </html> 在写了以前的例子之后,我发现了一个更好,更简单的实现方式.使用此代码,您将按照通常的方式继承相同的按钮. <!doctype html> <html lang="en" ng-app="app" ng-controller="MainController"> <head> <meta charset="UTF-8"> <title>Document</title> <meta name="google-signin-client_id" content="CLIENTID.apps.googleusercontent.com"> </head> <body> <google-sign-in-button button-id="uniqueid" options="options"></google-sign-in-button> <script src="https://apis.google.com/js/platform.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script> <script> angular.module('app',[]) .controller('MainController',function($scope) { //for more options visit https://developers.google.com/identity/sign-in/web/reference#gapisignin2renderwzxhzdk114idwzxhzdk115_wzxhzdk116optionswzxhzdk117 $scope.options = { 'onsuccess': function(response) { console.log(response); } } } ]) .directive('googleSignInButton',function() { return { scope: { buttonId: '@',options: '&' },template: '<div></div>',link: function(scope,element,attrs) { var div = element.find('div')[0]; div.id = attrs.buttonId; gapi.signin2.render(div.id,scope.options()); //render a google button,first argument is an id,second options } }; }); </script> </body> </html> (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
