在Node.js的和AngularJS CORS [英] CORS in Node.js and AngularJS

问题描述

我有一个CORS问题，我的应用程序。

I have a CORS problem with my app.

我的栈的Node.js与前preSS 4 并使用AngularJS的 Restangular

My stack is Node.js with Express 4 and AngularJS using Restangular

我已经尝试了一些东西（例如），但我不断收到：

I already have tried a few things (for example) but I keep getting:

XMLHttpRequest cannot load http://localhost:8080/api/users. Request header field Content-Type is not allowed by Access-Control-Allow-Headers.

在服务器端我有这样的标题：

In the server side I have this headers:

app.all('/*', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  res.header("Access-Control-Allow-Methods", "GET, POST","PUT");
  next();
});

在AngularJS部分我使用这样的：

In the AngularJS part I am using this:

$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];

和我做与Restangular的帖子是这样的：

And I am doing the post with Restangular like this:

var baseUsers = Restangular.all('users');
....
....
baseUsers.post(newUser).then(function(user){
console.log(user);
});

还有一件事，在Node.js的服务器，我安慰了 req.method 和它说选项 ，我真的不知道为什么。

One more thing, in the Node.js server I am consoling the req.method and it says OPTIONS, I really don't know why.

也许是愚蠢的东西，希望有人能帮助我。

Perhaps is something silly, hope someone can help me.

谢谢！

推荐答案

更改 -

res.header("Access-Control-Allow-Headers", "X-Requested-With");

到

res.header("Access-Control-Allow-Headers", "X-Requested-With, Content-Type");
