MSSQL/WMI/PowerShell结合篇（四）PowerShell发送微信信息

本文介绍如何通过PowerShell发送微信信息

先申请企业微信(企业、政府、组织三种类型)，通过PowerShell调用企业微信的API群发接口发送微信信息，API详细信息可参考企业微信开发者文档

以下为PowerShell调用企业微信API发送文本信息

----Script File: send_WeChat.ps1

param($param1,$param2,$param3)

##设置16-32位长度的密钥

function Set-Key {

param([string]$string)

$length = $string.length

$pad = 32-$length

if (($length -lt 16) -or ($length -gt 32)) {Throw "String must be between 16 and 32 characters"}

$encoding = New-Object System.Text.ASCIIEncoding

$bytes = $encoding.GetBytes($string + "0" * $pad)

return $bytes

}

##解密方法

function Get-EncryptedData {

param($key,$data)

$data | ConvertTo-SecureString -key $key |

ForEach-Object {[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($_))}

}

##发送微信方法

function send_WeChat_To_DBA {

Param(

[String]$corpid,

[String]$pwd,

[String]$Content

)

$auth_string = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$corpid&corpsecret=$pwd"

$auth_values = Invoke-RestMethod $auth_string

$token = $auth_values.access_token

$body="{

`"toparty`":`"receive group id`",

`"agentid`":`"your agent id`",

`"text`":{

`"content`":`"$content`"

},

`"msgtype`":`"text`"

}"

$CN=[System.Text.Encoding]::UTF8.GetBytes($body)

Invoke-RestMethod "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=$token" -ContentType "application/json" -Method Post -Body $CN

}

##解析帐号密码

$cidstr= Get-Content E:Monitorcidstr.txt;

$pwdstr = Get-Content E:Monitorkeystr.txt;

$cidkey = Set-Key $cidstr;

$pwdkey = Set-Key $pwdstr;

$cidfromFile = Get-Content E:Monitorwxcid.txt;

$pwdfromFile = Get-Content E:Monitorwxpwd.txt;

$corpid = Get-EncryptedData -data $cidfromFile -key $cidkey;

$pwd = Get-EncryptedData -data $pwdfromFile -key $pwdkey;

$content=$param1+$param2+$param3

##调用发送方法

send_WeChat_To_DBA -corpid $corpid -pwd $pwd -Content $content

##send_WeChat.ps1调用方式

E:Monitorsend_WeChat.ps1 $param1 $param2 $param3
