angularjs – Grunt Connect代理：404未找到

我正在使用 grunt-connect-proxy“^ 0.2.0”从我的angularjs应用程序代理api.该项目由yeoman角度发电机启动. @H_772_1@我按照说明here但是当使用代理时,我得到：

Failed to load resource: the server responded with a status of 404 (Not Found)
http://localhost:9000/api/users

@H_772_1@我的代理配置：

connect: {
  options: {
    port: 9000,// Change this to '0.0.0.0' to access the server from outside.
    hostname: 'localhost',livereload: 35729
  },proxies: [{
    context: '/api',// the context of the data service
    host: 'localhost',// wherever the data service is running
    port: 8080,// the port that the data service is running on
    https: false,xforWARD: false
  }],

@H_772_1@我的中间件：

livereload: {
    options: {
      open: true,base: '',middleware: function (connect,options) {
        var middlewares = [];

        middlewares.push(require('grunt-connect-proxy/lib/utils').proxyrequest);

        middlewares.push(connect.static('.tmp'));
        middlewares.push(connect.static('test'));
        middlewares.push(connect().use(
            '/bower_components',connect.static('./bower_components')
          ));
        middlewares.push(connect.static(appConfig.app));

        return middlewares;
      }
    }
  },

@H_772_1@我的服务任务

grunt.registerTask('serve','Compile then start a connect web server',function (target) {
  if (target === 'dist') {
    return grunt.task.run(['build','connect:dist:keepalive']);
  }

  grunt.task.run([
    'clean:server','wiredep','concurrent:server','autoprefixer:server','configureProxies:server','connect:livereload','watch'
  ]);
});

@H_772_1@编辑
localhost：8080 / users目前通过Postman返回403,因此API正在运行.
