帶表單身份驗證的PowerShell WebServiceProxy

Question

我正在與Remedy 9.1 Web服務構建一些接口。它使用Forms身份驗證進行配置以獲取WSDL。我希望將其保留在該配置中，以便更強大的Web服務得到保護。

我有一個解決方案的一部分，但我不知道他們可以一起工作，也許你知道一個解決方案？

這工作，如果我刪除窗體身份驗證：

function New-ObjectFromProxy { 
param($proxy, $proxyAttributeName, $typeName) 
# Locate the assembly for $proxy 
$attribute = $proxy | gm | where { $_.Name -eq $proxyAttributeName } 
$str = "`$assembly = [" + $attribute.TypeName + "].assembly" 
invoke-expression $str 
# Instantiate an AuthenticationHeaderValue object. 
$type = $assembly.getTypes() | where { $_.Name -eq $typeName } 

    return $assembly.CreateInstance($type) 
} 
$Now = get-date -Format G 
$Q = "'System Broadcast End Date' >= """ + $Now + """" 

$proxy = New-WebServiceProxy -Uri "https://mycompany-itsm.columncloud.com/arsys/WSDL/public/servername/CFG%3ABroadcast" 
$authHeader = New-ObjectFromProxy -proxy $proxy -proxyAttributeName "AuthenticationInfoValue" -typeName "AuthenticationInfo" 
$authHeader.userName = "username" 
$authHeader.password = "password" 
$proxy.AuthenticationInfoValue = $authHeader 
$Response = $proxy.GetList($Q,"","") 
$Response | format-Table Broadcast_Start_Date, Broadcast_Message 

但是，如果我移動Web服務後面的窗體身份驗證的背後，我能到WSDL如果我這樣做：

#this is the url that you want will send thae request to 
$url = "https://mycompany-itsm.columncloud.com/arsys/servlet/LoginServlet" 
#here you can set your POST params 

$parameters = "username=username&pwd=ppaasswwoorrdd&encpwd=1&ipoverride=0&initialState=-1&timezone=-28800000&goto=/arsys/WSDL/protected/servername/HPD_IncidentInterface_Create_WS" 
#creating the xmlHtpp system object    
$http_request = New-Object -ComObject Msxml2.XMLHTTP 
$http_request.open('POST', $url, $false) 
#Setting required header of the request 
$http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded") 
$http_request.setRequestHeader("Content-length", $parameters.length) 
#Assigning the params to the request 
$Resp = $http_request.send($parameters) 
echo $http_request.responseText 

我想找到一個解決方案將這些解決方案結合在一起，以使用表單認證來訪問WSDL並創建一個webServiceProxy對象。也許我的google-fu很弱，但我還沒有找到new-webserviceProxy的formsauth解決方案。

來自POSHCODE網站的原始碼。更新到添加formsauth

基本上我不得不使用回機器來找出這是如何完成之前，它是由新的WebServiceProxy超級簡單。我啓動了一個Web請求，用表單身份驗證數據發佈並獲取對話的cookie。如果我的cookie過期了，我會去找一個新的（可能會解釋我的腰圍）。

7年前發佈他的代碼的巨大道具給Oisin Grehan。

這樣稱呼它： \新WebServiceProxy-FormsAuth.ps1 -url 「https://mycompany/WSDL/public/servername/CFG%3ABroadcast」 - 命名空間 「的MyStuff」 -cookies $ CookieJar -lurl 「https://mycompany/servlet/LoginServlet」 -postData「用戶名=用戶名& PWD = ppaasswwoorrdd & encpwd = 1 & ipoverride = 0 &的初始化狀態= -1 &時區= -28800000"
