Question

我正在使用Remedy 9.1 Web服务构建一些接口。它配置了Forms身份验证以进入WSDL。我希望将其保留在该配置中，以便更强大的Web服务保持受保护。

我有部分解决方案，但我不确定它们是否可以一起工作，也许您知道解决方案？

如果我删除表单auth：

，则此方法有效

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，如果我将webservice移回到表单身份验证之后，如果我这样做，我可以访问WSDL：

#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

我想找到一个解决方案，将这些解决方案组合在一起，使用表单auth来获取WSDL并创建一个webServiceProxy对象。也许我的google-fu很弱，但我还没有找到new-webserviceProxy的formauth解决方案。

Answer 1

来自POSHCODE网站的原始代码。更新以添加formauth

基本上我必须使用back-machine的方式来弄清楚如何通过new-WebServiceProxy使它变得非常简单。我启动了一个Web请求，使用表单身份验证数据发布并获取对话的cookie。如果我的cookie过期，我会得到一个新的（可能会解释我的腰围）。

Oisin Grehan在7年前发布他的代码的巨大道具。

这样称呼它：。\ New-WebServiceProxy-FormsAuth.ps1 -Url＆＃34; https://mycompany/WSDL/public/servername/CFG%3ABroadcast＆＃34; -Namespace＆＃34; mystuff＆＃34; -Cookies $ CookieJar -lurl＆＃34; https://mycompany/servlet/LoginServlet＆＃34; -postData＆＃34; username = username＆amp; pwd = ppaasswwoorrdd＆amp; encpwd = 1＆amp; ipoverride = 0＆amp; initialState = -1＆amp; timezone = -28800000＆＃34;
