我正在尝试使用节点child_process执行curl以从本地网络中的共享文件夹获取JSON文件(大约220Ko).但它实际上返回了一个我无法解决的缓冲问题.这是我的代码:

var exec = require('child_process').exec;

var execute = function(command, callback){
    exec(command, function(error, stdout, stderr){ callback(error, stdout); });
};

execute("curl http://" + ip + "/file.json", function(err, json, outerr) {
    if(err) throw err;
    console.log(json);
})

这是我得到的错误:

if(err) throw err;
          ^
Error: stdout maxBuffer exceeded.

我正在使用Jasmine来测试我的角度应用程序,并希望监视一个匿名函数.使用angular-notify服务https://github.com/cgross/angular-notify,我想知道是否已经调用了通知功能.

这是我的控制器:

angular.module('module').controller('MyCtrl', function($scope, MyService, notify) {

  $scope.isValid = function(obj) {
    if (!MyService.isNameValid(obj.name)) {
      notify({ message:'Name not valid', classes: ['alert'] });
      return false;
    }
  }
});

这是我的测试:

'use strict';

describe('Test MyCtrl', function () {
  var scope, $location, createController, controller, notify;

  beforeEach(module('module'));

  beforeEach(inject(function ($rootScope, $controller, _$location_, _notify_) {
    $location = _$location_;
    scope = $rootScope.$new();
    notify = _notify_;

    notify = jasmine.createSpy('spy').andReturn('test');

    createController = function() {
      return $controller('MyCtrl', {
        '$scope': scope
      });
    };
  }));

  it('should call notify', function() {
    spyOn(notify);
    controller …
