我尝试修复错误：XMLHttpRequest无法加载http://localhost:1337/en/auth/forgetpass/email.请求标头字段Access-Control-Allow-Origin不允许Access-Control-Allow-Origin.

当我不激活我的拦截器时它运作良好.我没有这个错误.当我激活它时,我有错误.

在我的.config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我设置下面的代码：

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网络标签的结果是：

我仍然得到同样的错误.一个主意？

非常感谢！

我将响应和请求标头与拦截器及其进行了比较.

我改变我的代码如下,它的工作原理.

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,OPTIONS';*/

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

在我的sails.js cors setup config中我评论了方法和标题.它运作良好.

module.exports.cors = {
