我有一个棘轮聊天服务器文件

use Ratchet\Server\IoServer;
use Ratchet\WebSocket\WsServer;
use MyAppChat\Chat;
require dirname(__DIR__) . '/vendor/autoload.php';
$server = IoServer::factory(
    new WsServer(
        new Chat()
    )
  , 26666
);
$server->run();

我使用Websocket连接,ws它工作正常

if ("WebSocket" in window) {
    var ws = new WebSocket("ws://ratchet.mydomain.org:8888");
    ws.onopen = function() {
        // Web Socket is connected. You can send data by send() method.
        ws.send("message to send");
    };
    ws.onmessage = function (evt) { 
        var received_msg = evt.data;
    };
    ws.onclose = function() { 
        // websocket is closed. 
    };
} else {

我有一个集合,称为article_category哪个商店都article_id属于category_id具有数据格式的类别.

集合1:article_category

{
  "article_id": 2015110920343902,
  "all_category_id": [5,8,10]
}

然后我有其他收集称为article哪个存储我的所有帖子

收集2:文章

{
  "title": "This is example rows in article collection"
  "article_id": 2015110920343902,
},
{
  "title": "Something change"
  "article_id": 2015110920343903,
},
{
  "title": "This is another rows",
  "article_id": 2015110920343904,
}

现在,我想执行的MongoDB查询发现title与regex同时category_id必须等于8.这是我的查询,但不起作用.

db.article.aggregate(
{
  $match: 
  {
    title: 
    {
       $regex: /example/
    }
  }
},
{
    $lookup:
       {
         from: "article_category",
         pipeline: [
            { $match: { category_id: 8 } } …

我想在我的血腥请求中添加一个自定义标题,这是我的代码,但它不起作用.

var datasource = new Bloodhound({
    datumTokenizer: Bloodhound.tokenizers.whitespace,
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    remote: {
        url: url,
        prepare: function (query, settings) {
            var authHeaders;
            settings.type = "POST";
            settings.data = param + '=' + query;
            settings.headers = {
                'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
            };


            return settings;
        },
        wildcard: '%QUERY'
    }
});

任何的想法？

我使用 Laravel 5.4，现在我想对控制器进行动态路由，这意味着我可以直接访问UserController和Profile函数抛出路由，例如。

GET http://localhost/user/profile?userid=123

上面的示例网址意愿访问UserController和功能profile与后动态参数?。如果我想访问不同的控制器，我只需要将userparam更改为Controllername。

我创建了一条这样的路线并且它有效。

Route::get('v1/{controller_name}/{function_name}/{query?}', function ($controller_name, $function_name){

    $app = app();
    $controller = $app->make('\App\Http\Controllers\Api\\'.$controller_name.'Controller');
    return $controller->callAction($function_name, $parameters = array());
});

但我不知道如何传递参数。

还有其他更好的方法来做到这一点吗？

我将我的Mac更新到1.9.4并安装Xcode 6,我创建了一个新项目并UIBubbleTable从项目中复制了源代码,之前我使用过这个库,并且根据我上次的检查工作仍然可以正常工作.

旧项目适用于此库,但新项目会出错.

我添加了每个需求框架,但仍然是错误.

这是我的错误日志,请帮忙.

当 PhpStorm 尝试修复一个常见错误时，我真是太疯狂了Method 'Bla bla' not found in class.

我已经在谷歌搜索了几天，希望找到解决这个问题的方法，但没有运气。

几乎我读过的每个单一主题都将我指向这个 laravel-ide-helper，但是在安装数千次之后（使用新的 laravel 项目），PhpStorm 仍然无法识别那些该死的方法。

我也在 PhpStorm 中安装了 laravel 插件，但仍然无法工作，现在该怎么办？

这是我的代码。

<?php

namespace App\Http\Controllers;

use App\Article;
use App\Menu;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Requestst;
use Illuminate\Support\Facades\Input;

class PagesController extends Controller
{
    public function index()
    {
        $article = Article::latest('published_at')->get();
        $data = array(
            'articles' => $article
        );
        return view('pages.index' , compact($data));
    }

    public function contact()
    {
        return view('pages.contact');
    }

    public  function about()
    {
        return view('pages.about');
    }
}

请帮忙。

我使用此代码将视频栏添加到视图控制器中.

self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 64, MAINSCREEN.size.width, self.searchBar.frame.size.height)];
self.searchBar.delegate = self;

self.searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchDisplayController.delegate = self;
self.searchDisplayController.searchResultsDataSource = self;

[self.view addSubview:self.searchBar];

self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 64 + self.searchBar.frame.size.height, MAINSCREEN.size.width, MAINSCREEN.size.height)];
self.tableView.delegate = self;
[self.view addSubview:self.tableView];

我必须以编程方式将搜索栏和表格视图添加到视图中,因为我希望搜索栏始终位于表格视图的顶部,因此我使用了这些代码.

不幸的是,有一个问题,当我修复位置时搜索栏没有动画,CGRectMake所以我必须创建自己的动画来处理这个代码的问题.

我有一个数组,现在我将这个数组放入for loop显示此数组中的每个项目,但我想要设置项目限制(每列4个项目),这是我的代码.

<?php 
    $area = $custom_area_settings; //is an array with 5 element
    for($i=0;$i<=count($area->custom_area_list) - 1; $i++):
        if($area->custom_area_list[$i]->top_show):
            echo '<div class="sub-column column'.$i.'">';
            echo '<p class="line"> ' . $area->custom_area_list[$i]->header . '</p>';
            echo '</div>';
        endif;
    endfor;
?>

在这段代码中,div column$i已经创建了每次循环运行但是我只想在循环运行4次时创建这个div,4次后这个div将再次创建,8次后这个div将再次创建并继续...

这是我想要的结果.

Column 1           Column 2
---------------    ---------------
item 1             item 5
item 2             item 6
item 3             item 7
item 4             item 8

这是我现在得到的结果

Column 1
---------------------
item 1
Column 2
---------------------
item 2

请帮忙.
