使用Powershell中的SOAP使用參數呈現SSRS報告

Question

我一直在玩這個沒有運氣的日子。基本上我試圖建立一個簡單的庫來使用Powershell來呈現SSRS報告。我正在使用Powershell試圖稍後緩解開發（而不是爲每個項目編寫C＃應用程序）。大多數情況下，這將用於安排報告的各種事情。

我有報告渲染主要是在Powershell中工作。我無法弄清楚的一件事是如何在調用渲染方法之前向報告提供參數。我發現很多與C＃和VB（我在其他SSRS項目中使用過）有關的代碼，但是我無法將其轉換爲Powershell。

由於我是Powershell的新手，我不熟悉正確的方法。下面是我一直使用的代碼：這對那些不需要參數，顯然報告工作正常

$ReportExecutionURI = "http://glitas10//ReportServer//ReportExecution2005.asmx?wsdl" 
$ReportPath = "/Financial/ExpenseReportStub" 
$format = "PDF" 

$deviceInfo = "<DeviceInfo><NoHeader>True</NoHeader></DeviceInfo>" 
$extension = "" 
$mimeType = "" 
$encoding = "" 
$warnings = $null 
$streamIDs = $null 

$Reports = New-WebServiceProxy -Uri $ReportExecutionURI -UseDefaultCredential 

# Load the report 
$Report = $Reports.GetType().GetMethod("LoadReport").Invoke($Reports, @($ReportPath, $null)) 

# Render the report 
$RenderOutput = $Reports.Render($format, $deviceInfo, [ref] $extension, [ref] $mimeType, [ref] $encoding, [ref] $warnings, [ref] $streamIDs) 

。

有關我需要做什麼來實例化正確的對象和傳遞參數的任何想法？

下面是我最終使用的解決方案的一些信息，以防其他人需要這樣做。它工作得很好。

工作的第一種方法是構建一個由Powershell腳本使用的DLL。這工作得很好，但它會導致兩個問題。首先，你的腳本有來裝載一個DLL。其次，這個DLL綁定到特定的SSRS服務器。爲了訪問另一臺服務器，你必須使用多個DLL。

最後，我回到使用Web代理。這裏的關鍵是使用名稱空間，以便您可以實例化一個ParameterValue對象。這裏的代碼：

# Create a proxy to the SSRS server and give it the namespace of 'RS' to use for 
# instantiating objects later. This class will also be used to create a report 
# object. 
$reportServerURI = "http://<SERVER>/ReportServer/ReportExecution2005.asmx?WSDL" 
$RS = New-WebServiceProxy -Class 'RS' -NameSpace 'RS' -Uri $reportServerURI -UseDefaultCredential 
$RS.Url = $reportServerURI 

# Set up some variables to hold referenced results from Render 
$deviceInfo = "<DeviceInfo><NoHeader>True</NoHeader></DeviceInfo>" 
$extension = "" 
$mimeType = "" 
$encoding = "" 
$warnings = $null 
$streamIDs = $null 

# Next we need to load the report. Since Powershell cannot pass a null string 
# (it instead just passses ""), we have to use GetMethod/Invoke to call the 
# function that returns the report object. This will load the report in the 
# report server object, as well as create a report object that can be used to 
# discover information about the report. It's not used in this code, but it can 
# be used to discover information about what parameters are needed to execute 
# the report. 
$reportPath = "/PathTo/Report" 
$Report = $RS.GetType().GetMethod("LoadReport").Invoke($RS, @($reportPath, $null)) 

# Report parameters are handled by creating an array of ParameterValue objects. 
$parameters = @() 

$parameters += New-Object RS.ParameterValue 
$parameters[0].Name = "Parameter 1" 
$parameters[0].Value = "Value" 

$parameters += New-Object RS.ParameterValue 
$parameters[1].Name = "Parameter 2" 
$parameters[1].Value = "Value" 

# Add the parameter array to the service. Note that this returns some 
# information about the report that is about to be executed. 
$RS.SetExecutionParameters($parameters, "en-us") > $null 

# Render the report to a byte array. The first argument is the report format. 
# The formats I've tested are: PDF, XML, CSV, WORD (.doc), EXCEL (.xls), 
# IMAGE (.tif), MHTML (.mhtml). 
$RenderOutput = $RS.Render('PDF', 
    $deviceInfo, 
    [ref] $extension, 
    [ref] $mimeType, 
    [ref] $encoding, 
    [ref] $warnings, 
    [ref] $streamIDs 
) 

# Convert array bytes to file and write 
$Stream = New-Object System.IO.FileStream("output.pdf"), Create, Write 
$Stream.Write($RenderOutput, 0, $RenderOutput.Length) 
$Stream.Close() 

它似乎很容易，它是。此方法運行得非常好，並且是我現在用於呈現和發送計劃報告的方法，因爲它比內置的SSRS計劃提供了更多的靈活性。另外，它相對較快。我用來發送報告的一個腳本可以呈現並每分鐘發送大約20-30個報告。

有同樣的問題，而且要發送生成的MHT文件作爲電子郵件正文： 下面發現工作 老CDO.Message是我發現的唯一的事情，允許發送一個MHTML文件作爲電子郵件身體。 下面是VB程序的（工作）翻譯 舊但簡單;-)！

################## Send MHTML email ############################## 
# use antiquated CDO to send mhtml as email body 

$smtpServer = "my-mail-server" 
$smtpSubject = "MHT file sent as body of email" 
$smtpTo = "you@work.com" 
$smtpFrom = "me@home.org" 
$MHTMLfile = "my-MHT-File.mht 
# e.g. from an SSRS.Render 


$AdoDbStream = New-Object -ComObject ADODB.Stream 
$AdoDbStream.Charset = "ascii" 
$AdoDbStream.Open() 
$AdoDbStream.LoadFromFile($MHTMLfile) 
$CdoMessage = New-Object -ComObject CDO.Message 
$CdoMessage.DataSource.OpenObject($AdoDbStream,"_Stream") 

$SendUsingPort = 2 
$smtpPort = 25 

$cfg = "http://schemas.microsoft.com/cdo/configuration/" 
$CdoMessage.Configuration.Fields.Item($cfg + "sendusing") = $SendUsingPort 
$CdoMessage.Configuration.Fields.Item($cfg + "smtpserver") = $SmtpServer 
$CdoMessage.Configuration.Fields.Item($cfg + "smtpserverport") = $smtpPort 

$CdoMessage.To  = $smtpTo 
$CdoMessage.From = $smtpFrom 
$CdoMessage.Subject = $smtpSubject 

$CdoMessage.MimeFormatted = $true 
$CdoMessage.Configuration.Fields.Update() 

WRITE-HOST "Sending email" 
$CdoMessage.Send()
