网上找遍了国内和国外的资料，没有能够为动态增加的文件加上时间戳的，进过分析Yii2源码，发现其实非常简单：
修改main.php
'assetManager' => [
'appendTimestamp' => true,
],
$bundle=AppAsset::register($this);
$bundle->js[]='js/windowview.js';
$bundle->css[]='css/robot.css';
解决办法是设置format为raw:
[
'attribute' => 'attribute',
'format' => 'raw',
'value' => function ($model, $key, $index, $column) {
return Html::a($model->title, ['view', 'id' => $model->id], ['target' => '_blank']);
},
],
Yii::$app->params['myVar']
Yii::app()->session['myvar']
或者通过Flash Message
首先，需要再控制器添加参数
class SiteController extends CController {
public $myvar;
//...
然后在layout/main.php获取控制器变量
$this->context->myvar
Yii::$app->controller->myvar

Yii 2 的 2.1x版本后，采用asset-packagist.org给bower提速，效果明显，旧版本Yii要升级到新版本可以采用以下步骤：
"config": {
"process-timeout": 1800,
"fxp-asset": {
"enabled": false
}
},
"repositories": [
{
"type": "composer",
"url": "https://asset-packagist.org"
}
]
'aliases' => [
'@bower' => '@vendor/bower-asset',
'@npm' => '@vendor/npm-asset',
],
composer clear-cache
composer install
公司服务器连接数超过10K了，查了下大多数是没有即时回收，采用tcp复用容易后程序出现了故障，以前一直看到说PHP持久连接有问题，所以没怎么用，最近有机会试了下。
非常香，连接数直接降低到几百了，目前观察数周没有问题。
netstat -n | wc -l # 总连接数
netstat -n | grep -i time_wait | wc -l # time_wait 连接数
netstat -anp # 查看占用端口过多的程序网上大部分解决方案是修改sysctl.conf回收重用ipv4连接，但是可能带来其他问题
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_timestamps=1
net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_fin_timeout=30
net.ipv4.tcp_keepalive_time = 600修改nginx.conf
upstream fastcgi_backend {
server 127.0.0.1:9000;
keepalive 60;
}
location ~ \.php$ {
fastcgi_pass fastcgi_backend;
fastcgi_keep_conn on;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
主要是 fastcgi_keep_conn on 与 upstream 的 keepalive
upstream wxpic {
keepalive 60;
server 127.0.0.1:xxx;
}
server {
keepalive_requests 10000; # 默认100
location / {
proxy_http_version 1.1;
proxy_set_header Connection "";
}
}主要是 proxy_http_version, proxy_set_header Connection ""以及keepalive_requests
修改yii数据库配置采用长链接
'db' => [
'class' => 'yii\db\Connection',
'dsn' => '*', 'username' => '*',
'password' => '*',
'charset' => 'utf8mb4',
'attributes' => [
PDO::ATTR_PERSISTENT => true
]
],
参考官方安装指南Yii advanced template installation提到：
It uses asset-packagist for managing bower and npm package dependencies through Composer. Also you can use asset-plugin, as in earlier versions, but it works slowly.
找到
"config": {
"process-timeout": 1800,
"fxp-asset":{
"installer-paths": {
"npm-asset-library": "vendor/npm",
"bower-asset-library": "vendor/bower"
}
}
},
"replace": {
"bower-asset/jquery": ">=1.11.0",
"bower-asset/inputmask": ">=3.2.0",
"bower-asset/punycode": ">=1.3.0",
"bower-asset/yii2-pjax": ">=2.0.0"
}
修改为
"config": {
"process-timeout": 1800,
"fxp-asset": {
"enabled": false
}
},
"repositories": [
{
"type": "composer",
"url": "https://asset-packagist.org"
}
]
修改config/main.php
'aliases' => [
'@bower' => '@vendor/bower-asset',
'@npm' => '@vendor/npm-asset',
],
from https://asset-packagist.org/
Composer + Bower + NPM = friends forever!
This repository allows installation of Bower and NPM packages as native Composer packages.
NO plugins and NO Node.js are required.
At the moment we’ve added most popular Bower and NPM packages 4000+ each.
In case Composer fails to install some asset package, use the search line at the top of the page to check specific package health.
For NPM scoped packages use scope--package instead of @scope/package, e.g. npm-asset/pusher--chatkit.
Got tired of fxp/composer-asset-plugin.
Got tired of fxp/composer-asset-plugin.
It’s a good project with nice idea and good implementation. But it has some issues: it slows down composer update a lot and requires global installation, so affects all projects. Also there are Travis and Scrutinizer integration special problems, that are a bit annoying.
Extension of Yii 2 Framework, which is wrapper for bootstrap-gtreetable plugin, on the other hand it provides functionality which allows to save the nodes states into database. http://gtreetable2.gilek.net
The nested sets behavior for the Yii framework.
jQuery TreeGrid Extension for Yii 2
This is the jQuery TreeGrid extension for Yii 2. It encapsulates TreeGrid component in terms of Yii widgets, and thus makes using TreeGrid component in Yii applications extremely easy.
An enhanced tree management module from Krajee with inbuilt jQuery plugins and Yii widgets for tree node manipulation and management using nested sets. The module provides ability to manage hierarchical data stored using nested sets. It utilizes the yii2-nested-sets extension to manage the tree structure in your database. Refer the documentation for yii2-nested-sets extension before you start using this module. The yii2-tree-manager module includes two major widgets TreeView and TreeViewInput. In addition, it includes module level settings to easily configure your tree management preferences. It includes a Tree Model which includes inbuilt tree management flags and rules. The model implements and uses a TreeTrait. So one can choose to extend from the Tree Model or implement their own model that uses the TreeTrait. It also includes a NodeController that allows you to manage tree nodes easily via ajax. The tree view widgets and jQuery plugins are built from scratch by Krajee entirely without using any third party plugins. The TreeView is designed using HTML5, jQuery & CSS3 features to work along with the Yii 2 framework.
View a complete demo for TreeView or TreeViewInput.
