MSSQL/WMI/PowerShell結合篇（四）PowerShell發送微信信息

本文介紹如何通過PowerShell發送微信信息

先申請企業微信(企業、政府、組織三種類型)，通過PowerShell調用企業微信的API群發接口發送微信信息，API詳細信息可參考企業微信開發者文檔

以下為PowerShell調用企業微信API發送文本信息

----Script File: send_WeChat.ps1

param($param1,$param2,$param3)

##設置16-32位長度的密鑰

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($_))}

}

##發送微信方法

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

}

##解析帳號密碼

$cidstr= Get-Content E:\Monitor\cidstr.txt;

$pwdstr = Get-Content E:\Monitor\keystr.txt;

$cidkey = Set-Key $cidstr;

$pwdkey = Set-Key $pwdstr;

$cidfromFile = Get-Content E:\Monitor\wxcid.txt;

$pwdfromFile = Get-Content E:\Monitor\wxpwd.txt;

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

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

$content=$param1+$param2+$param3

##調用發送方法

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

##send_WeChat.ps1調用方式

E:\Monitor\send_WeChat.ps1 $param1 $param2 $param3
