使用javascript fullstack进行Passport google身份验证

Question

我正在尝试在我的应用程序中添加带有护照的google身份验证,这是使用yeoman fullstack-generator生成的.

在我的登录控制器内我有这个请求:

$scope.googleAuth = function(){
  $http.get('/auth/google');
};

但是,当我调用此函数时,我有这个错误:

XMLHttpRequest cannot load https://accounts.google.com/o/oauth2/auth?response_type=code&redirect_uri=h…d=<my-client-ID-here>. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access.

我试图修复在express.js文件中添加中间件层的问题:

app.use(function (req, res, next) {

  // Website you wish to allow to connect
  res.setHeader('Access-Control-Allow-Origin', 'http://localhost:9000');

  // Request methods you wish to allow
  res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

  // Request headers you wish to allow
  res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');

  // Set to true if you need the website to include cookies in the requests sent
  // to the API (e.g. in case you use sessions)
  res.setHeader('Access-Control-Allow-Credentials', true);

  // Pass to next layer of middleware
  next();
});

但它仍然无法正常工作.这是正确的解决方案吗？它安全吗？

Answer 1

我使用超链接而不是按钮修复了问题,如下所示

<a target="_self" href="/auth/google" class="btn btn-danger">Google+</a>

我使用target="_self"其他角度重定向到主页,因为,我认为,它认为/auth/google是我的应用程序的路线.
