angularjs – 角/节点/ Express/Passport跨域问题 – 启用CORS Passport Facebook验证

Chrome上出现的错误是：@H_673_2@

XMLhttprequest cAnnot load https://www.facebook.com/dialog/oauth?response_type=code&redirect_uri=http%…%3A8080%2Fauth%2Ffacebook%2FcallBACk&scope=email&client_id=598171076960591. 
No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://localhost:8080' is therefore not allowed access.

我使用的路线是这样简单的：@H_673_2@

// =====================================
// FACEBOOK ROUTES =====================
// =====================================
// route for facebook authentication and login

app.get('/auth/facebook',passport.authenticate('facebook',{ scope : 'email' }));

// handle the callBACk after facebook has authenticated the user
app.get('/auth/facebook/callBACk',{
        successRedirect : '/home',failureRedirect : '/login'
    }));

这是在我的angularJS文件上调用路由(我也尝试使用Credentials设置：truE)：@H_673_2@

$http.get('/auth/facebook')
    .success(function(responsE) {

    }).error(function(responsE){

    });

我在StackOverflow和其他论坛上发现了十几种解决方案。@H_673_2@

>我尝试在route.js文件上的路由之前添加：@H_673_2@

app.all('*',function(req,res,next) {
  res.header('Access-Control-Allow-Origin','*');
  res.header("Access-Control-Allow-Headers","Content-Type,X-CSRF-Token,X-requested-With,Accept,Accept-Version,Content-Length,Content-MD5,Date,X-Api-Version,X-File-Name");
  res.header('Access-Control-Allow-Methods','GET,POST,PUT,HEAD,deletE,OPTIONS');
  res.header('Access-Control-Allow-Credentials',truE);

  if ('OPTIONS' == req.method) {
      res.send(200);
  } else {
      next();
  }
});

>我尝试在server.js文件中添加(请注意，我将标题更改为setHeader，但我已经尝试过)@H_673_2@

app.use(function(req,next) {
  res.setHeader('Access-Control-Allow-Origin','*');
  res.setHeader('Access-Control-Allow-Headers','Content-Type,X-requested-With');
  res.setHeader('Access-Control-Allow-Methods',OPTIONS');
  res.setHeader('Access-Control-Allow-Credentials',truE);

  if ('OPTIONS' == req.method) {
    res.send(200);
  } else {
    next();
  }

 });

 require('./app/routes.js')(app,passport);

>我尝试在我的app.js文件(angularJS配置)中添加：@H_673_2@

$httpProvider.defaultS.UseXDomain = true;
delete $httpProvider.defaults.headers.common['X-requested-With'];
$httpProvider.defaults.withCredentials = true;

无论如何，我不知道还有什么要做的。我在网上找到的一切都不行。@H_673_28@有机会与我使用AngularJS路由有关吗？我没有看到任何这样的事情的原因，但是我已经猜出来了。@H_673_2@

我的情况非常类似于这个：@H_673_28@Angular/Node/Express/Passport – Issues when connecting to facebook(CORS)@H_673_2@
