Question

当我想删除用户时，为什么Restangular会出现406错误？卷曲请求工作：

curl -X DELETE -v "http://localhost:3000/api/v1/users/1"

这是Restangular方法：

removeOne: function(user) {
      var deferred;
      deferred = $q.defer();
      if (_.isUndefined(user.id) || _.isNaN(user.id)) {
        AlertsServ.logError(err);
        deferred.reject(err);
      } else {
        user.remove().then(function(result) {
          return deferred.resolve(result);
        }, function(err) {
          AlertsServ.logError(err);
          console.log(err);
          return deferred.reject(err);
        });
      }
      return deferred.promise;
    }

和Rails方法（我使用Grape框架）：

    delete ':id' do
      user = User.find(params[:id])
      user.update(hidden: true)
      user
    end

Answer 1

只需将RestangularProvider.setDefaultHeaders（{＆＃39; Content-Type＆＃39;：＆＃39; application / json＆＃39;}）添加到module.config。

Restangular和Rails，DELETE 406不可接受，卷曲工作
