我正在尝试使用我的GET请求发送我的会话cookie iron-ajax.现在,请求中根本没有cookie.有什么建议？

<iron-ajax
  auto
  url="{{apiHost}}/users/me"
  withCredentials="true"
  handle-as="json"
  versbose="true"
  requestHeaders='{"Cookie":"curves"}'
></iron-ajax>

使用入门套件2中的模板,是否可以将应用程序抽屉放在app-header？现在,应用程序抽屉从视口顶部开始,并在旁边列化app-header.

我希望我的应用程序像谷歌保持和谷歌云控制台,其中应用程序标题跨越视口的整个宽度,应用程序抽屉从下面开始.

在阅读了元素目录之后app-layout,我没有看到设置它的官方api /属性.我尝试了一些但没有成功的事情:

<app-drawer-layout fullbleed>
  <!-- Drawer content -->
    <app-header condenses reveals effects="waterfall">
      <app-toolbar>
        <paper-icon-button icon="menu" drawer-toggle></paper-icon-button>
        <div main-title>My App</div>
      </app-toolbar>
    </app-header>

  <app-drawer>
    <app-toolbar>Menu</app-toolbar>
    <iron-selector selected="[[page]]" attr-for-selected="name" class="drawer-list" role="navigation">
      <a name="view1" href="/view1">View One</a>
      <a name="view2" href="/view2">View Two</a>
      <a name="view3" href="/view3">View Three</a>
    </iron-selector>
  </app-drawer>

我有一个dom-repeat模板,我希望能够实时对列表进行排序.所以,我采用的方式是下面的方式.但是,当用户从中选择新选择时,我需要一种方法来刷新dom-repeat paper-menu.

通常,对结果集数组的修改会执行此操作.但在这种情况下,对列表进行排序的更改不需要添加或删除该数组中的任何内容(因此没有数组突变).

我怎么能<template is="dom-repeat" items="[[pic.results173]]" as="url" sort="_sortList">刷新？

<paper-menu-button>
  <paper-button class="dropdown-trigger" raised>
    <iron-icon icon="visibility"></iron-icon>
    <span>View By</span>
  </paper-button>
  <paper-menu id="viewMode" class="dropdown-content" selected="0">
    <paper-item>Most Recent</paper-item>
    <paper-item>Least Recent</paper-item>
    <paper-item>Highest Price</paper-item>

  <template is="dom-repeat" items="[[pic.results173]]" 
    as="url" sort="_sortList">

  _sortList: function(first, second) {
    var el = this.$.viewMode;
    var listMode;
    switch(el.selected) {
      case 0:
        listMode = this._mostRecent(first , second);
        break;
    }
    return listMode;
  },

foo = document.getElementById("outer");

function cycleIt() {
    if (client.browser.Firefox) {
        foo.addEventListener("animationend", updateClassName, true);
    } else {
        foo.addEventListener("webkitAnimationEnd", updateClassName, true);
    }
}

function updateClassName() {

    var z = foo.getAttribute("class");

    if ( z == "a" ) {
        foo.className = "b";
    } else if ( z == "b" ) {
        foo.className = "c"
    } else if ( z == "c" ) {
        foo.className = "d"
    } else {
        foo.className = "a"
    }
    return foo;
}

有人在Javascript聊天频道上告诉我,我应该为if if语句创建一个哈希表.我该怎么办呢？

    var xml = null;
    xml = new XMLHttpRequest();
    xml.open("get", who, false);
            xml.send(null);
    if ((xml.status >= 200 && xml.status <= 300) || xml.status == 304) {
    var hi = xml.responseText;
    } else {
    alert("No Internet Connection! You will have to enter information by hand");
    };

我想设置这个警报,如果没有互联网连接,它会这样说.但是,浏览器停止/挂起xml.send(null)与NS_ERROR_FAILURE:失败.如何为连接正确设置测试？

在angular.js中,我有一个按钮,提供下拉菜单.我遇到的问题是,始终如一,我必须单击按钮两次以显示下拉菜单.我第一次点击按钮,我看到它亮起来...所以点击注册.但是,我必须再次点击它以显示下拉菜单.是什么造成的？

指示:

angular.module('main.vips')
.directive('actionButton', ['ActionButtonService', function(ActionButtonService) {
    openAddVipModal = function() {
        return $modal.open({
            templateUrl: 'vips/addvip.html',
            controller: 'AddVipCtrl',
            size: 'lg',
            windowClass: 'modal-fullscreen vip-modal'
        });
    }

  return {
    templateUrl: 'vips/directives/actionButton.html',
    restrict: "AE",
    replace: true,
    transclude: false,
    scope: {
      'label': "@?",
      'icon': "@?",
      'type': "@?",
      'actions': "=?"
    },
    link: function(scope, element, attrs) {
        scope.actions = ActionButtonService[attrs.type];
    }
  }
}]);

服务:

angular.module('main.vips')
.factory('ActionButtonService', function() {
  var actions = {};
  actions.loadbalancer = [
    {
      label: "Create New VIP",
      fn: function() {
        return openAddVipModal();
      },
      icon: …

我正在使用Python服务器与Python的Requests模块进行http调用.请求调用在常规python shell中没有问题.但是在Flask中,它出现了"引发ConnectionError(e)"的错误.这真的很痛,因为我需要使用python在后端进行url调用,因为我不能使用javascript因为跨域限制.

flask python # cat myapp.py
import json
import requests
from flask import Flask
app = Flask(__name__)


@app.route('/', defaults={'path': ''}, methods=('GET', 'POST'))
@app.route('/<path:path>', methods=('GET', 'POST'))
def catch_all(path):
    link = "http://10.44.11.33/api/v1/counts/latest/15"
    r = requests.get(link)
    return "Hello World"


if __name__ == '__main__':
    app.run(debug=True, host="0.0.0.0")

错误输出:

def raw_list(function):
    @wraps(function)
    def wrapper(args, producer_data):
        print producer_data[2]
        tenant, token, url = producer_data
        body, status_code = do_request(url, token)
        return function(args, producer_data)
    return wrapper

    # consumer is aliased to producer.
    uuid = args['uuid']
    producer_data[2] = producer_data[2] + "/" + uuid + "/members"

我有几个函数可以获取URL,对其进行修改,并使用URL进行API调用.出于这个原因,我为API调用部分创建了一个包装函数.因此,每个函数只需要改变URL并用包装函数进行修饰.

但我遇到的问题是,变异的URL代码producer_data[2] = producer_data[2] + "/" + uuid + "/members"似乎在函数装饰器代码运行之后运行,而不是之前.因此,使用原始URL而不是变异URL.

如何修复此逻辑流并将其调用到使用变异URL进行API调用的位置？

使用Restangular,get方法/ promise将解析,但传递给.then()的结果为空...使用console.log(data); 显示未定义.我检查了chrome debug中的网络选项卡,xhr请求很好,200次成功...正文中有一个完整的json响应.

使用addResponseInterceptor,我发现data参数是未定义的,但response参数显示包含带有负载/ body的data属性的对象.

所以,我还在挠头......为什么数据参数未定义,而响应对象在response.data中正确包含json有效负载/响应？

我需要解决这个问题,以便在解析时将结果传递给.then().

createNode: function(node) {
      var account = "9936";
      var eventId = "0fd6afd9-4aa0-a5c9-ff0b3e60cdcf";
      Restangular.addResponseInterceptor(function(data, operation, what, url, response, deferred) {
          console.log("````````````````");
          console.log(data);
          console.log(operation);
          console.log(what);
          console.log(url);
          console.log(response);
          console.log(deferred);
          console.log("````````````````");
      });

这很奇怪......我第一次输入输入框时,会弹出typeahead模板,但会显示为空.但如果退格并再次执行...那么模板就会填充.就像有某种竞争条件一样typeahead-template-url.Ater认为,问题会消失,直到下一页刷新.有任何想法吗？

        dropDownItems = [];

Angular UI路由器问题

当$state.go("main.loadbalancer.readonly");在resolve块中激活时,main.loadbalancer.vips状态控制器VipListCtrl(仅控制器)仍然在解析后加载.

由于状态main.loadbalancer.readonly被激活,如何让控制器VipListCtrl取消而不加载？

我尝试使用一个承诺并且永远不会解除承诺,但是UI路由器似乎永远都会坚持这个决心.

angular.module("main.loadbalancer", ["ui.bootstrap", "ui.router"]).config(function($stateProvider) {
  return $stateProvider.state("main.loadbalancer", {
    url: "device/:id",
    views: {
      "content@": {
        templateUrl: "loadbalancer/loadbalancer.html",
        controller: "LoadBalancerCtrl"
      }
    }
  }).state("main.loadbalancer.vips", {
    resolve: {
        isDeviceReadOnly: function($state) {
        if (!$state.current.data['deviceId']) {
          $state.go("main.loadbalancer.readonly"); //THIS IS RAN...NEED CONTROLLER
                                                   //VipListCtrl TO NOT RUN AFTERWARDS
        }
      }
    },
    url: "/vips",
    templateUrl: "loadbalancer/vip-table.html",
    controller: "VipListCtrl"
  }).state("main.loadbalancer.nodes", {
    url: "/nodes",
    templateUrl: "loadbalancer/node-table.html",
    controller: "NodeListCtrl"
  }).state("main.loadbalancer.admin", {
    url: "/admin",

我是新来的咖喱功能,有人建议我使用它们.我想知道这个:

var updateNodeStorage;

updateNodeStorage = function(devicesToCheck) {
  var nodesToCallOut;
  nodesToCallOut = devicesToCheck.filter(function(device) {
    var nodeExistInStorage;
    return nodeExistInStorage = nodeStorage.devices.every(function(nodeInStorage) {
      return device.id !== nodeInStorage.id;
    });
  });
  nodesToCallOut.forEach(function(node) {
    getNodeProtocol(node.id);
  });
};

为此代码使用咖喱函数是否有益？如果是这样,我将在何处以及如何使用它？
