使用 vuex 的 mapState
在 vue 中：
<template>
<div>
{{user.name}}
</div>
</template>
<script>
import {mapState} from 'vuex';
export default {
computed: {
...mapState({
user: state => state.user
})
}
}
</script>
在 store 中：
export default {
state: {
user: {}
},
}
实现mysql自动备份的简单脚本
#!/bin/bash
#chmod 700 backup.sh
#crontab -e
#每天4点， mysql备份数据
#0 4 * * * /home/cron/mysql_backup.sh
host="localhost"
user="dbname"
password="dbname"
db_name="dbname"
#backup directory
base_dir="/home/backup"
backup_log="${base_dir}/mysql_backup.log"
backup_path=${base_dir}
#file info
date=$(date +"%Y-%m-%d")
filename=$backup_path/$db_name-$date.sql.gz
#back up
mkdir -p $backup_path
mysqldump --user=$user --password=$password --host=$host $db_name | gzip > $filename
#Delete files older than 10 days
find $backup_path/* -mtime +10 -exec rm {} \;
echo "backup finished at $(date +'%Y-%m-%d %H:%M:%S')" >> "$backup_log"
js删除数组里的某个元素
// Array Remove - By John Resig (MIT Licensed)
Array.prototype.remove = function(from, to) {
var rest = this.slice((to || from) + 1 || this.length);
this.length = from < 0 ? this.length + from : from;
return this.push.apply(this, rest);
};
// 移除数组中的第二项
array.remove(1);
// 移除数组中的倒数第二项
array.remove(-2);
// 移除数组中的第二项和第三项（从第二项开始，删除2个元素）
array.remove(1,2);
// 移除数组中的最后一项和倒数第二项（数组中的最后两项）
array.remove(-2,-1);
scss 使用 @font-face 引入 fonticon 字体报错
webpack 内置的路径检索在使用特定方式引入文件时，会出现无法加载字体的问题，例如以下方式：
vue
<style lang="scss" src="./path-to-file.scss"></style>
scss
@font-face {
font-family: "iconfont";
src: url('./iconfont/iconfont.eot?t=1501135137439'); /* IE9*/
src: url('./iconfont/iconfont.eot?t=1501135137439#iefix') format('embedded-opentype'), /* IE6-IE8 */
url('./iconfont/iconfont.woff?t=1501135137439') format('woff'), /* chrome, firefox */
url('./iconfont/iconfont.ttf?t=1501135137439') format('truetype'), /* chrome, firefox, opera, Safari, Android, iOS 4.2+*/
url('./iconfont/iconfont.svg?t=1501135137439#iconfont') format('svg'); /* iOS 4.1- */
}
下载的字体
如果是从 iconfont 下载的字体，将字体放到访问根目录下。
比如 laravel 的访问根目录是 /public，在里面创建字体目录，如 static/fonts/iconfont，将字体放在该目录下。
在 scss 文件中将路径改为绝对路径。如上面的例子，则可以写为：
@font-face {
font-family: "iconfont";
src: url('/static/fonts/iconfont/iconfont.eot?t=1501135137439'); /* IE9*/
src: url('/static/fonts/iconfont/iconfont.eot?t=1501135137439#iefix') format('embedded-opentype'), /* IE6-IE8 */
url('/static/fonts/iconfont/iconfont.woff?t=1501135137439') format('woff'), /* chrome, firefox */
url('/static/fonts/iconfont/iconfont.ttf?t=1501135137439') format('truetype'), /* chrome, firefox, opera, Safari, Android, iOS 4.2+*/
url('/static/fonts/iconfont/iconfont.svg?t=1501135137439#iconfont') format('svg'); /* iOS 4.1- */
}
其实就是不要 loader 自动寻找文件，而直接输出路径，我们只要事先准备好对应的文件即可。
fontawesome
加载 fontawesome 需要先定义 $fa-font-path 变量，如下：
$fa-font-path: "~font-awesome/fonts";
@import '~font-awesome/scss/font-awesome';
laravel 5.5 安装使用 passport
使用 Composer 安装 Passport ：
composer require laravel/passport:~4.0
Laravel 5.6 已经发布，最新的
laravel/passport版本为5.0适配 Laravel 5.6，所以我们需要使用 Laravel 5.5 的适配版本4.0。
如果安装过程中遇到 paragonie/random_compat 版本冲突的问题，可以先执行以下命令将其降级为 2.0 的版本。
composer require paragonie/random_compat:^2.0
