Powershell - 将CSV数据发送到表格中的电子邮件

时间：2017-12-06 17:01:46

标签： powershell csv email import-csv

现在我的目标是从网址下载包含威胁数据的CSV，捕获两列，文件名和DeviceName，这两列都是CSV中的标题。然后，我想将这些数据导出到电子邮件中的一行，然后由我们的安全团队中的两名成员以明文格式进行审核。目标是让他们不必直接从CSV下载和复制粘贴，因为CSV中存在大量无关数据。

这是一个非常简单的脚本，所以一切正常。我的问题是：如何从csv中提取两列数据并将其写入电子邮件正文？理想情况下，在某种表中，两列是对齐的。

我在网上找到了一些资源，最明显的是从PowerShell界面获取任何对象的脚本，将对象（表格）转换为HTML，然后通过电子邮件发送：https://gallery.technet.microsoft.com/scriptcenter/bd0c8d87-466f-4488-92a2-0f726cb6f4cd

这是完美的，因为这正是我想要做的。我只是不确定如何正确地将数据从CSV传递到powershell函数。

请注意，这也是我在powershell中的第一个项目，它主要是通过technet文档和我在网上找到的代码示例碎片拼凑而成的。我是一名初级系统管理员，所以没有大量的编程背景。

谢谢束！

这次设法取得了一些成功，但不幸的是，通过电子邮件发送的输出是一个乱码列表，与CSV中的任何数据都不对应。

我很确定我的错误就在这里，但我不确定我在哪里失败：

$csv = Import-Csv $output | Select "File Name",DeviceName | ConvertTo-Html

我的其余代码如下：

管理得出答案！

首先，我在链接中抛弃了Send-HTMLEmail，因为它既不必要也不特别有用。

我的固定工作代码是

#Defines variables
$url = "mysite.com/ThreatsDataReport.csv"
$output = "$PWD\ThreatsDataReport.csv"
$emailSMTPServer = "smtp.mydomain.com"
$emailFrom = "reportingemail@domain.com"
$emailRecipients = @("Foo <foo@domain.com>"), "Bar <bar@domain.com>")
$emailSubject = "Cylance Reporting"

(New-Object System.Net.WebClient).DownloadFile($url, $output)
#Downloads the CSV from $url and saves it to $output

#Sets HTML Head Information
$a = "<style>"
$a = $a + "BODY{background-color:peachpuff;}"
$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"
$a = $a + "TH{border-width: 1px;padding: 0px;border-style: solid;border-color: black;background-color:thistle}"
$a = $a + "TD{border-width: 1px;padding: 0px;border-style: solid;border-color: black;background-color:palegoldenrod}"
$a = $a + "</style>"




$csv = Import-Csv $output | Select "File Name",DeviceName,"File Path" | ConvertTo-Html -head $a -Body "<H2>Cylance Weekly Report</H2>"
#Imports the CSV saved to $output.
#Selects File Name, Device Name, and File Path columns, then converts to HTML using the Head +Body Information
$emailBody = "$csv"

#defines the body text of the email. Note that this has to be a string, $emailBody = $csv will not work on its own. 

Send-MailMessage -From $emailFrom -To $emailRecipients -SmtpServer $emailSMTPServer -subject $emailSubject -Body $emailBody -BodyAsHtml
#Sends the actual email

感谢您发布此信息。我将其用作模板，并扩展了一些我想要的东西。我的csv数据来自PRTG。

我可以使用Invoke-WebRequest来下载csv。插入-UseBasicParsing允许使用任务计划程序计划脚本。

$WebResponse = Invoke-WebRequest -UseBasicParsing "URL to CSV DATA"
$output = $WebResponse.Content

我还为内容添加了一些过滤和排序逻辑

#Uses data from WebResponse, filters, sorts, and selects columns
#Multiple sections of the resultant html output allows for formatting
#Evaulates results set and sets alternate header when null
#Sets results and converts to html while inserting HTML head
$prep1 = ConvertFrom-Csv $output | ? Status -like Down | sort -Property 'Device', 'Sensor'| Select Probe,Device,Sensor
if (!$prep1) { $out1 = '<H3>No Sensors in <span style="color: #ff0000;">Down</span> State</H3>' }
else {$out1 = $prep1 | ConvertTo-Html -head $head -Body '<H3>Sensors in <span style="color: #ff0000;">Down</span> State</H3>'}

当我想要具有不同标题的数据的不同部分时，我重复了上面的内容，然后通过将所有内容附加在一起来完成它。

#Create HTML Body
$emailBody = "$out1 $out2"

这是完成的脚本。

#Define variables
$WebResponse = Invoke-WebRequest -UseBasicParsing "URL with output=csvtable"
$output = $WebResponse.Content
$emailSMTPServer = "smtp.mydomain.com"
$emailFrom = "reportingemail@domain.com"
$emailRecipients = @("Foo <foo@domain.com>"), "Bar <bar@domain.com>")
$emailSubject = "PRTG Status Report"

#Sets HTML Head Information when result set is not Null
$head = "<style>"
$head = $head + "BODY{}"
$head = $head + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"
$head = $head + "TH{border-width: 1px;padding: 1px;border-style: solid;border-color: black;background-color:gainsboro}"
$head = $head + "TD{border-width: 1px;padding: 1px;border-style: solid;border-color: black;background-color:palegoldenrod}"
$head = $head + "</style>"

#Uses data from WebResponse, filters, sorts, and selects columns
#Multiple sections of the resultant html output allows for formatting
#Evaulates results set and sets alternate header when null
#Sets results and converts to html while inserting HTML head

$prep1 = ConvertFrom-Csv $output | ? Status -like Down | sort -Property 'Device', 'Sensor'| Select Probe,Device,Sensor
if (!$prep1) { $out1 = '<H3>No Sensors in <span style="color: #ff0000;">Down</span> State</H3>' }
else {$out1 = $prep1 | ConvertTo-Html -head $head -Body '<H3>Sensors in <span style="color: #ff0000;">Down</span> State</H3>'}

$prep2 = ConvertFrom-Csv $output | ? Status -like Warning | ? Sensor -Notmatch 'Windows Updates Status' |sort -Property 'Device', 'Sensor'| Select Probe,Device,Sensor
if (!$prep2) { $out2 = '<H3>No Sensors in <span style="color: #ffcc00;">Warning</span> State</H3>' }
else {$out2 = $prep2 | ConvertTo-Html -head $head -Body '<H3>Sensors in <span style="color: #ffcc00;">Warning</span> State</H3>'}

#Create HTML Body
$emailBody = "$out1 $out2"

#Send email 
Send-MailMessage -From $emailFrom -To $emailRecipients -SmtpServer $emailSMTPServer -subject $emailSubject -Body $emailBody -BodyAsHtml

如果您只希望CSV文件中的第一行包含这些列名，您可以执行以下操作：

$csv = Import-Csv $output | Select-Object -First 1
$emailBody = "File Name: {0}`r`nDevice Name: {1}" -f
  $csv."File Name", $csv.DeviceName
$params = @{
  "From"       = $emailFrom
  "To"         = $emailRecipients
  "SmtpServer" = $emailSMTPServer
  "Subject"    = $emailSubject
  "Body"       = $emailBody
}
Send-MailMessage @params

要获取多行输出，您可以执行以下操作：

$emailBody = Import-Csv $output |
  Select-Object "File Name",DeviceName |
  Format-Table -AutoSize | Out-String
$params = @{
  "From"       = $emailFrom
  "To"         = $emailRecipients
  "SmtpServer" = $emailSMTPServer
  "Subject"    = $emailSubject
  "Body"       = $emailBody
}
Send-MailMessage @params
