shell使用微信公众号发送模板消息

Posted 2022-03-05 5ifbk

1.配置微信公众号

由于没有认证的公众号，只能通过自己申请的个人订阅号（可以自行申请），并到开发者工具中开通公众平台测试帐号实现该功能。
1.获取测试公众号appID和appsecret

 

*2.关注测试号二维码获取用户openid

 

 

3.新增模板获取模板ID

 

 

得到模板id： OA0PX8pqc2X7t_y05y5GxZ8LutBpu341FIYSeQOkno

2.通过脚本实现消息发送

#!/bin/sh

#全局配置--
#微信公众号appID
appID=wxe14bed8b9882c259

#微信公众号appsecret
appsecret=f97826cd18236872b07e53e330ae02b6

#微信公众号发送消息模板
tpl_id=0P67Th60_C_xExoCIdDJyEUap26r_-MR5VJ1g1qBNjw
#消息模板：
#   first.DATA 
#   项目名称：name.DATA 
#   报警时间：date.DATA
#
#   remark.DATA

#获取微信公众号AccessToken，并缓存到本地 函数
getAccessToken()
    if [ -f "$HOME/.wechat_accesstoken" ]; then
        access_token=`cat $HOME/.wechat_accesstoken | awk -F":" ‘print $1‘`
        expires_in=`cat $HOME/.wechat_accesstoken | awk -F":" ‘print $2‘`
        time=`cat $HOME/.wechat_accesstoken | awk -F":" ‘print $3‘`
            if [ -z $access_token ] || [ -z $expires_in ] || [ -z $time ]; then
            rm -f $HOME/.wechat_accesstoken
            getAccessToken 
        fi
    else
        content=$(curl "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appID&secret=$appsecret")
        echo "get content: $content"
        access_token=`echo $content | awk -F "\\"" ‘print $4‘`
        expires_in=`echo $content | awk -F "\\"" ‘print $7‘ | cut -d"" -f1|cut -c2-`
        echo "access_token = $access_token"
        echo "expires_in = $expires_in"
        time=$(date +%s)
        echo "$access_token:$expires_in:$time" > $HOME/.wechat_accesstoken

        if [ -z $access_token ] || [ -z $expires_in ] || [ -z $time ]; then
                    echo "not get access_token"
                    exit 0
        fi
        fi

    remain=$[$(date +%s) - $time]
    limit=$[$expires_in - 60]
    if [ $remain -gt $limit ]; then

关于微信公众号接口说明查看如下接口wiki： 

https://mp.weixin.qq.com/wiki
1.开始开发->获取access_token
2.消息管理->模板消息接口

3.接收到消息

执行命令脚本即上述shell脚本内容。记得设置脚本执行权限 chmod +x sendMessageForWechat
shell
./sendMessageForWechat -u o4bHbvjL9aWoRCa29vdOQ9aJMq0w -s "192.168.1.90磁盘空间不足" -n 测试系统 -t "2017-01-15 13:00:10" -d "磁盘已使用超过80%，剩余5G，请及时处理" -l "http://m.baidu.com"
