Official website Documents

Http://www.yiiframework.com/doc-2.0/guide-structure-assets.html

The Yii directory runs

Asset/template assets.php

Generates assets.php, which is a configuration template and modifies the following

<?php/** * Configuration file for the "Yii asset" console command. *//In the console environment, some path aliases could not exist. Please define These:yii::setalias (' @webroot ', __dir__.
'/web ');
Yii::setalias (' @web ', '/');  return [///Adjust Command/callback for JavaScript files compressing://' jscompressor ' => ' Java-jar Compiler.jar {from}--js_output_file {to} ', ' Jscompressor ' => ' Java-jar Yuicompressor.jar--type js {from}-o {to} ',//Adjust com  Mand/callback for CSS files compressing: ' Csscompressor ' => ' Java-jar Yuicompressor.jar---type CSS {from}-o {to} ',// The list of asset bundles to compress: ' Bundles ' => [' app\assets\appasset ', ' yii\web\yiiasset ', ' Yii\web\jqueryasset ' ,],//Asset bundle for compression output: ' Targets ' => [' All ' => [' class ' => ' Yii\web\assetbundle '], ' Basepat H ' => ' @webroot/assets ', ' baseurl ' => ' @web/assets ', ' js ' => ' js/all-{hash}.js ', ' css ' => ' css/all-{hash}.css ',],],//Asset manager ConfiguratIon: ' Assetmanager ' => [' basepath ' => ' @webroot/assets ', ' baseurl ' => ' @web/assets ',],]; 

Here CSS and JS are all used Yuicompressor

Then create the Js,css folder under Web/assets and set permissions 777

Install Java command line, under Ubuntu

sudo apt-get install Default-jre

Download Yuicompressor.jar:

Https://github.com/yui/yuicompressor/releases

Put it in the Yii root directory.

Run

./yii Asset Assets.php config/assets-dev.php

assets-dev.php files are generated under Config

Add in Config/web.php's component configuration

' Assetmanager ' => [
' Bundles ' => require (__dir__. '/assets-'. Yii_env. '. php '),
],

F5 Refresh the page can see the use of compressed CSS and JS

If you want to cancel, comment out the corresponding code in the web.php

PS:YII2 controllers, method naming conventions, and access routes

If the module name or controller name or action name is in camel format, then each uppercase word in the route is connected with "-". Such as

Datetimecontroller::actionfastforward the corresponding route is Date-time/fast-forward.

For example: Http://dfms.com/backend/web/api-test/test-upload

Api-test is the controller name

Test-upload is the method name
