Event::emit('user.nav.render', $object);
還有加這個(gè)事件是啥作用，不加有什么問題嗎？

不要在 plugin/user/api/Template.php 里改代碼，在你的插件或者主項(xiàng)目/config/event.php配置中添加對應(yīng)的菜單.

比如
plugin/nat/config/event.php中添加如下

use plugin\foo\app\service\UserEvent;
return [
    // 當(dāng)有用戶注冊時(shí)
    'user.register' => [
        [UserEvent::class, 'onUserRegister']
    ],
    // 當(dāng)渲染用戶端導(dǎo)航菜單時(shí)
    'user.nav.render' => [
        [UserEvent::class, 'onUserNavRender']
    ],
    // 當(dāng)渲染用戶中心左側(cè)邊欄時(shí)
    'user.sidebar.render' => [
        [UserEvent::class, 'onUserSidebarRender']
    ],
];

plugin/nat/app/service/UserEvent.php

<?php

namespace plugin\nat\app\service;

use plugin\nat\app\model\NatApp;
use plugin\user\app\model\User as UserModel;
use stdClass;

/**

class UserEvent
{
    /**

     */
    public function onUserRegister(UserModel $user)
    {
        $request = request();
        $host = $request->host(false);
        // 創(chuàng)建一個(gè)默認(rèn)內(nèi)網(wǎng)穿透應(yīng)用
        if (!filter_var($host, FILTER_VALIDATE_IP)) {
            $username = $user->username;
            $domain = "$username.$host";
            if (!NatApp::where('domain', $domain)->first()) {
                $app = new NatApp;
                $app->user_id = $user->id;
                $app->name = '我的應(yīng)用';
                $app->domain = $domain;
                $app->local_ip = '127.0.0.1';
                $app->local_port = 8787;
                $app->save();
            }
        }
    }

    /**

    public function onUserNavRender(stdClass $object)
    {
        $request = request();
        $path = $request ? $request->path() : '';
        // 添加內(nèi)網(wǎng)穿透自己的導(dǎo)航欄菜單
        $object->navs[] = [
            'name' => '內(nèi)網(wǎng)穿透',

    {
        $request = request();
        $path = $request ? $request->path() : '';
        // 添加內(nèi)網(wǎng)穿透自己的左側(cè)用戶中心菜單
        $object->sidebars[] = [
            'name' => '內(nèi)網(wǎng)穿透',
            'items' => [
                ['name' => '用戶中心菜單1', 'url' => '/app/nat/apps', 'class' => $path === '/app/nat/apps' ? 'active' : ''],
                ['name' => '用戶中心菜單2', 'url' => '/app/nat/token', 'class' => $path === '/app/nat/token' ? 'active' : ''],
            ]
        ];
    }
}

結(jié)果類似如下

用戶模塊建議整個(gè)簡單的文檔，類似webman-admin

如果我每個(gè)左側(cè)邊欄不一樣該怎么辦呢？我看siderbar那段模板代碼是公用的。但是我想在一些控制器里面設(shè)置不同的siderbar，我定義了event，也寫了對應(yīng)的代碼，但是沒有展示，是怎么回事呢？
event代碼：

    // 當(dāng)渲染教育中心左側(cè)邊欄時(shí)
    'teach.sidebar.render' => [
        [app\event\Teach::class, 'onTeachSidebarRender'],
    ],

app\event\Teach代碼：

<?php

namespace app\event;

use stdClass;

class Teach
{
    public function onTeachSidebarRender(stdClass $object)
    {
        $request = request();
        $path = $request ? $request->path() : '';
        // 動態(tài)添加自己的導(dǎo)航欄菜單
        $object->sidebars[] = [
            'name' => '各種工具',
            'items' => [
                ['name' => '視頻工具', 'url' => '/tool/video/index', 'class' => $path === '/tool/video/index' ? 'active' : ''],
                ['name' => '教育工具', 'url' => '/tool/teach/mathHomework', 'class' => $path === '/tool/teach/mathHomework' ? 'active' : ''],
            ],
        ];
        // 一個(gè)欄目一個(gè)數(shù)組，這樣好管理
        $object->sidebars[] = [
            'name' => '測試多個(gè)菜單',
            'items' => [
                ['name' => '視頻工具', 'url' => '/tool/video', 'class' => $path === '/tool/video' ? 'active' : ''],
                ['name' => '教育工具', 'url' => '/tool/teach', 'class' => $path === '/tool/teach' ? 'active' : ''],
            ],
        ];
    }

}

然后我在控制器里面觸發(fā)：

        $object = new stdClass();
        $object->sidebars = [];
        Event::emit('teach.sidebar.render', $object);

        $vars = [
            'operators' => array_keys(self::OPERATORS),
            'need' => 100,
            'sidebars' => $object->sidebars,
        ];

但是頁面沒有如期展示。
