调用 SOAP API 方法时的 PowerShell 'Cannot find overload'

Question

我正在尝试使用PowerShell调用SOAP API方法，但在向其传递参数时遇到问题。

我能够进行身份验证并拥有所有必需的权限。该方法可用。根据文档和WDSL，它有4个必需参数datetime、datetime、bool、int。我正在通过它们，但结果总是一样的错误：

Cannot find an overload for "GetFirstPageAlarms" and the argument count: "4".
At line:1 char:1
+ $alarmz = $Client.GetFirstPageAlarms([datetime]$endDate,[datetime]$en ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : NotSpecified: (:) [], MethodException
+ FullyQualifiedErrorId : MethodCountCouldNotFindBest

以下是我的尝试：

# Connect to the API
$Client = New-WebServiceProxy -Uri $url -Credential get-credential
# Connects successfully
# Define parameters
$startDate = (get-date).AddDays(-2)
$endDate = get-date
$allUsers = $true
$maximumResultsPerPage = 10
# Call the method
$results = $Client.GetFirstPageAlarms([datetime]$endDate,[datetime]$endDate,[boolean]$True,[int]"5")
# Fails here.
# Alternative, also fails with same error
$Client.GetFirstPageAlarms("2020-11-01","2020-12-01","True","5")
# And another alternative failing
$Client.GetFirstPageAlarms([datetime]"2020-11-01",[datetime]"2020-12-01",[boolean]$True,[int]"5")

从谷歌搜索来看，Overload错误似乎与所需参数的错误类型有关。我试图指定类型，但仍然失败。

我尝试了更多的东西，到处寻找信息，没有选择和想法了。我希望有人能帮忙。谢谢

方法的WSDL定义：

<xs:element name="GetFirstPageAlarms">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" name="startDate" type="xs:dateTime"/>
<xs:element minOccurs="0" name="endDate" type="xs:dateTime"/>
<xs:element minOccurs="0" name="allUsers" type="xs:boolean"/>
<xs:element minOccurs="0" name="maximumResultsPerPage" type="xs:int"/>
</xs:sequence>
</xs:complexType>
</xs:element>

我想这已经解决了：

$client | get-member GetFirstPageAlarms

返回

TypeName   : Microsoft.PowerShell.Commands.NewWebserviceProxy.AutogeneratedTypes.WebServiceProxy1ices_AlarmServiceBasicAuth_svc.AlarmService
Name       : GetFirstPageAlarms
MemberType : Method
Definition : Microsoft.PowerShell.Commands.NewWebserviceProxy.AutogeneratedTypes.WebServiceProxy1ices_AlarmServiceBasicAuth_svc.AlarmSummaryDataResults GetFirstPageAlarms(datetime startDate, bool startDateSpecified, datetime
endDate, bool endDateSpecified, bool allUsers, bool allUsersSpecified, int maximumResultsPerPage, bool maximumResultsPerPageSpecified)

有一些隐藏的属性需要添加。出于某种原因，医生没有提到他们。

$Client.GetFirstPageAlarms([datetime]"2020-11-01",[bool]$true,[datetime]"2020-12-01",[bool]$true,[bool]$true,[bool]$true,[int]"5",[bool]$true)

出现新错误：

Exception calling "GetFirstPageAlarms" with "8" argument(s): "An error occurred when verifying security for the message."
At line:1 char:1
+ $Client.GetFirstPageAlarms([datetime]"2020-11-01",[bool]$true,[dateti ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : SoapHeaderException

但这可能是一个单独的问题，与作战手册中的问题无关。
