AngularJS/SailsJS :Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers

Question

我正在 Angular js和sails.js(node.js框架)之间的cors问题上挣扎

我尝试修复错误:XMLHttpRequest无法加载http://localhost:1337/en/auth/forgetpass/email。 Access-Control-Allow-Headers不允许请求 header 字段Access-Control-Allow-Origin。

当我不激活拦截器时，它会很好地工作。我没有这个错误。激活它时，出现错误。

在我的.config文件中，我设置了以下代码:

  //Enable cross domain calls
$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];

$httpProvider.defaults.headers.common['Access-Control-Allow-Headers'] = '*';
$httpProvider.defaults.headers.common['Access-Control-Allow-Origin'] = '*';
$httpProvider.defaults.headers.common['Access-Control-Allow-Methods'] = 'GET,POST,PUT,HEAD,DELETE,OPTIONS';

$httpProvider.interceptors.push('TokenInterceptor');

然后在我的拦截器中，设置以下代码:

    return {
    request: function (config) {
      var id = Session.getprop('id');
      if(id) {
        config.headers = config.headers || {};
        config.headers.Authorization = 'Bearer ' + id;
      }
        return config;
    }, ...

最后，chrome网络标签页的结果是:

Request URL:http://localhost:1337/en/auth/forgetpass/email
Request Method:OPTIONS
Status Code:200 OK

而且我仍然遇到相同的错误。一个主意？

非常感谢!

好的，我终于找到了问题。

我将响应和请求 header 与拦截器以及它进行了比较。

我如下更改我的代码，它可以工作。

在angularjs的app.js中

我评论了所有标题部分。

   //Enable cross domain calls
  /*  $httpProvider.defaults.useXDomain = true;

//Remove the header used to identify ajax call  that would prevent CORS from working
delete $httpProvider.defaults.headers.common['X-Requested-With'];

$httpProvider.defaults.headers.common['Access-Control-Allow-Headers'] = 'origin, content-type, accept';
$httpProvider.defaults.headers.common['Access-Control-Allow-Origin'] = '*';
$httpProvider.defaults.headers.common['Access-Control-Allow-Methods'] = 'GET,POST,PUT,HEAD,DELETE,OPTIONS';*/

$httpProvider.interceptors.push('TokenInterceptor');

在我的sails.js cors设置配置中，我评论了方法和 header 。而且效果很好。

    module.exports.cors = {
