Custom Object for API

jcannon · January 25, 2018, 7:45am

I am working with an API, and this one is requiring the first parameter passed to it be an object and not a string. I think I need to create an object and set the “.ID” string field to the value I am pulling from SQL.

$OSSNAWS = New-WebServiceProxy -Uri "http://localhost/websiteA/Web.asmx?wsdl" -Namespace WebServiceProxy -Credential $Credential 

$applicationUri = "http://websiteB.com/Apps/SMessages/MPage.aspx" 

$extDeviceID = '00AA11BB22CC' 

$devID = New-Object -TypeName PSObject 

Add-Member -InputObject $devID -MemberType NoteProperty -Name Id -Value $extDeviceID 

$devID.Id = $extDeviceID 

$OSSNBWS.LaunchClientApplication($devID,$applicationUri)

The API is the “LaunchClientApplication” and the parameter that needs to be an object is the $devID.

When I run the above, this is the error I get back.

Cannot convert argument "0", with value: "@{Id=00AA11BB22CC}", for "LaunchClientApplication" to type "WebServiceProxy.ExternalId": "Cannot convert the "@{Id=00AA11BB22CC}" value of type "System.Management.Automation .PSCustomObject" to type "WebServiceProxy.ExternalId"." At C:\PowerShellScripts\Test-.ps1:23 char:38 + $OSSNBWS.LaunchClientApplication <<<< ($devID,$applicationUri) + CategoryInfo : NotSpecified: (:) [], MethodException + FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument

I have been playing around and researching this and cannot seem to get that parameter right. I feel that there is a rather simple solution that is just out of my reach.

Thanks.

This is tricky to answer because we don’t have access to the API you’re using which is probably why you’ve not had a response to your post.

The error message is given because the LaunchClientApplication method is unable to cast (convert) your PSCustomObject to the object of type ExternalID that it is expecting.

In the first instance, I’d be inclined just to pass it a string and see if you get a similar error.

Yes, I figured that would be the case, so I hoped at least someone would ask for more information.

I tried passing just the $extDeviceID variable as a string and received a similar error. I think my problem is that I do not know how to make an object as a type “WebServiceProxy” with the method “.ID”. I found some help in another forum with someone that knows C# but not PowerShell and they posted this:

"You need to create the object and set the “.Id” string field to the value of the external device Id. Here is some C# code fragment.

        String appURL = “https://myServerURL.com/WebFolder/WebApp.aspx”;
        String extDeviceId = “MySTB_External_Device_ID”;
        UINotificationsWS.DeviceExternalId devID = new UINotificationsWS.DeviceExternalId();
        devID.Id = extDeviceId;
        uinws.LaunchClientApplication(devID, appURL);

"

I do not know C#. Hoping someone can help me translate.

Thanks for the response.

Can you pipe $OSSNAWS to Get-Member and post the results.

Yes, trying a cut and paste.

I was hoping to see a more obvious method for creating it but based on the C# example, I’m thinking something like this:

$OSSNAWS = New-WebServiceProxy -Uri "http://localhost/websiteA/Web.asmx?wsdl" -Namespace WebServiceProxy -Credential $Credential 

$applicationUri = "http://websiteB.com/Apps/SMessages/MPage.aspx" 

$extDeviceID = '00AA11BB22CC' 

$devID = New-Object WebServiceProxy.UINotificationsWS.DeviceExternalId

$devID.Id = $extDeviceID

$OSSNBWS.LaunchClientApplication($devID,$applicationUri)

Much thanks. I just tried that but I am still getting errors.

Ok, I based it off the example but the object type in the method definition is ExternalID not DeviceExternalID.

So you could try

$devID = New-Object WebServiceProxy.UINotificationsWS.ExternalId

or

$devID = New-Object WebServiceProxy.ExternalId

If those don’t work I think we’re clutching at straws without access to the documentation for the API.

I found the page where it shows the SOAP code for the API, but cannot seem to get it to display here, in this message. ???

I will look for more in the morning (EST). Much thanks for all the help.

Also;

Trying to post the SOAP code…

SOAP Code-01

SOAP Code-02

matt-bloomfield · January 30, 2018, 3:39pm

After creating the namespace can you see if the class’s static methods offer any clues. The C# example suggests the class has a method for creating the object:

WebServiceProxy.UINotificationsWS | Get-Member -Static

jcannon · January 30, 2018, 3:48pm

Do you mean this?

PS C:\> $OSSNBWS | Get-Member -static


   TypeName: WebServiceProxy.UINotificationsWS

Name                MemberType Definition                                                                                                                                                                  
----                ---------- ----------

GenerateXmlMappings Method     static bool GenerateXmlMappings(type type, System.Collections.ArrayList mappings), static hashtable GenerateXmlMappings(type[] types, System.Collections.ArrayList mappings)
ReferenceEquals     Method     static bool ReferenceEquals(System.Object objA, System.Object objB)

Or this?..

PS C:\> $OSSNBWS.LaunchClientApplication | Get-Member -static

ReferenceEquals Method     static bool ReferenceEquals(System.Object objA, System.Object objB)

Yes that’s what I was after but it doesn’t help One last thing that might be worth a try, I found an old Don Jones article that shows how to give your object a custom type name. I don’t know if that will fool it into thinking that’s what’s being passed.

https://technet.microsoft.com/en-us/library/hh750381.aspx

$OSSNAWS = New-WebServiceProxy -Uri "http://localhost/websiteA/Web.asmx?wsdl" -Namespace WebServiceProxy -Credential $Credential 

$applicationUri = "http://websiteB.com/Apps/SMessages/MPage.aspx" 

$extDeviceID = '00AA11BB22CC' 

$devID = New-Object -TypeName PSObject 

Add-Member -InputObject $devID -MemberType NoteProperty -Name Id -Value $extDeviceID 

$devID.PSObject.TypeNames.Insert(0,'WebServiceProxy.ExternalId')

$OSSNBWS.LaunchClientApplication($devID,$applicationUri)

If you pipe $devID to Get-Member you’ll now see the typename reported as WebServiceProxy.ExternalID instead of System.Management.Automation.PSCustomObject

jcannon · January 31, 2018, 7:26am

Much thanks. I will certainly check out that article!

Yeah, this is kicking my butt. Tried that code and received the following error.

PS C:\> C:\PowerShellScripts\Test-Crawler-02.ps1
Cannot convert argument "0", with value: "@{Id=00AA11BB22CC}", for "LaunchClientApplication" to type "WebServiceProxy.ExternalId": "Cannot convert the "@{Id=00AA11BB22CC}" value of type "WebServiceProxy.ExternalId
" to type "WebServiceProxy.ExternalId"."
At C:\PowerShellScripts\Test-Crawler-02.ps1:23 char:38
+ $OSSNBWS.LaunchClientApplication <<<< ($devID,$applicationUri)
    + CategoryInfo          : NotSpecified: (:) [], MethodException
    + FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument

You are right and that code does appear to change the type of $devID, but the API still did not like it.

PS C:\> $devid | Get-Member


   TypeName: WebServiceProxy.ExternalId

Name        MemberType   Definition                    
----        ----------   ----------                    
Equals      Method       bool Equals(System.Object obj)
GetHashCode Method       int GetHashCode()             
GetType     Method       type GetType()                
ToString    Method       string ToString()             
Id          NoteProperty System.String Id=00AA11BB22CC

I have reached out (again) to someone that might know how to work with this API. Fingers crossed.

Thanks so much for all the help. And if you have any other ideas, please let me know. And I will do the same. Believe it or not, this was suppose to be the easy part of the script I am trying to make. Little did I know…
