Having trouble trying to get JSON info from Spiceworks Website. RRS feed

  • Question

  • For some background on what I'm trying to do, Click here - http://community.spiceworks.com/topic/295123-fun-spiceworks-community-project?page=2#entry-2035675

    Spiceworks is a web based software package. If I am logged into the website I can enter this into a browser:


    and I get this back (Count of currently unassigned Tickets)


    When I try this:

    PS C:\> $page = (new-object net.webclient).DownloadString("http://servername:port/api/tickets.json?total_count=true&filter=unassigned")

    Exception calling "DownloadString" with "1" argument(s): "The remote server returned an error: (406) Not Acceptable."
    At line:1 char:1
    + $page = (new-object net.webclient).DownloadString("http://servername:port/api/tick ...
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
        + FullyQualifiedErrorId : WebException

    This may be because I'm not logged into the website, but I can't quite figure that part out, I'm trying some things now using the IE COM object, but I haven't gotten too far yet. 

    The goal is to take the above response and grab the number and use it to control a real world status indicator(already have that part figured out, just need to grab the damn number from the website).

    I'm a novice coder at best, and alot of this stuff is over my head, but I'm using this small project as a way to learn powershell and object oriented programming. I've learned alot since I've started working on it, but I've taken it as far as I can with my current knowledge.

  • Error 406 indicates that is probably error in the headers sent from your client. (Ie User-Agent, Accepted mime-types etc)...

    I would recomend using Fiddler to see your request and the answer going back, a great way of troubleshooting.

    If it is as I suspect you can try and add those headers on.

  • Also, if you are on PowerShell 3.0, try the Invoke-WebRequest cmdlet.

  • I am on Powershell 3.0. I upgraded just to get the Invoke-WebRequest cmdlet. I can get the main page to return code, but I'm unsure how to pass my username and password to the website before attempting to grab the unassigned count.

  • This is the login page. 

    It's from http://servername:port/login

    It doesn't show the name of the html file, so I'm assuming it's generated on the fly?

  • Ok. Seems to be "working".

    I think what you need to do is to first make a post-request with the user_email and user_password.

    $formFields = @{user_email='john doe'; user_password ='123'}

    $LoginPage = Invoke-WebRequest -Method POST -Uri <loginpage> -WebSession $sessionVariable -Body $formFields -ContentType "application/x-www-form-urlencoded"

    then the next request can be for the original url where the content is.

    I noticed that there is a authenticity_token field in the form, but hopefully you can ignore that one..

  • Thanks Dainel,

    I will try that. I also downloaded Fiddler and am reviewing the Invoke-WebRequest help. 

    I will post my results tomorrow.

  • It seems to be having a problem with the & in http://servername:port/api/tickets.json?total_count=true&filter=unassigned

    I tried quoting the & and then tried quoting the whole thing but no luck yet.

  • I'm not exactly sure it's logging me in. 

    I'm using a different URL to test this now instead of the json request, just so I can see if I'm getting authenticated. I don't think that I am, it looks like the login dialog. 

    $formFields = @{user_email='username'; user_password ='password'}

    $LoginPage = Invoke-WebRequest -Method POST -Uri http://server:port/login -WebSession $sessionVariable -Body $formFields -ContentType "application/x-www-form-urlencoded"

    $Unassigned = Invoke-WebRequest http://server:port/tickets/list/my_tickets

  • I would guess that you need to pick up the authenticity_token field and send also when logging in. Seems to be some additional security in that field..

    As for if you have encoding issues you can use [System.Web.HttpUtility]::UrlEncode to encode parts of the URL 

    Lastly I think that if you try the transaction by browser (still using Fiddler) you will se the "correct" flow of posts and can compare to what you are getting back now. Fiddler also let's you replay and make post directly from Fiddler so you can experiment before you implement it in PowerShell.

    I found this also: http://community.spiceworks.com/scripts/show/311-spiceworks-ticket-rss-atom-feed

  • I think I'll mess with Fiddler so I know what I'm trying to duplicate. Watching the instructional video's now. 

    Thanks alot for that link. I've searched spiceworks for weeks, never saw that one. 

    Thanks again for all your assistance so far.

  • Daniel's Suggestions have been very helpful. I'm still working on it. I think he's right with the Auth Token, though I don't yet know what one is, but I can see it when I use fiddler. 

    I'm not a web developer, so all of this is new to me, and in order for me to solve my problem, I have to have an understanding of what's going on behind the scenes. 

    This is a pet project so I am working on it when I'm caught up on other work. I'll post my findings as soon as I make some progress.

    As this is not only a powershell script issue, I would like to suggest you post in the MSDN and Official scripting guys forum as well.

  • Hi Nextonex -

    Have you made any headway with this project?

    I'm working on the same.



    Wednesday, November 13, 2013 5:46 PM
  • No, I had other projects and never got back to it. I would be interested in any progress you make and will continue to monitor this thread. 
    Wednesday, November 13, 2013 7:22 PM
  • This code doesn't look quite right:

    $formFields = @{user_email='username'; user_password ='password'}
    $LoginPage = Invoke-WebRequest -Method POST -Uri http://server:port/login -WebSession $sessionVariable -Body $formFields -ContentType "application/x-www-form-urlencoded"
    $Unassigned = Invoke-WebRequest http://server:port/tickets/list/my_tickets

    What you should be doing is passing the -SessionVariable parameter to the first Invoke-WebRequest call (loading the logon page).  This is a lot like -ErrorVariable, etc; you specify a variable name without a dollar sign, and it saves the session to that variable.  Then, in future calls to Invoke-WebRequest, you use -WebSession $variable .

    You can see an example of using this technique to log on to FaceBook in the Invoke-WebRequest help file:

    (Get-Help Invoke-WebRequest -Examples).examples.Example[1]

    Interesting about the blank cookie issue.  Rather than replacing ",," with "," (which only works if there isn't more than one consecutive blank entry in the list), you could do something like this to remove all blank entries from the list:

    $cookies = $r.Headers['Set-Cookie'] -split ',' -match '.' -join ','



    Also, on this line:

    Import-Module ($([System.Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory()) + "System.Web.dll")
    # it would probably be simpler to just do this:
    Add-Type -AssemblyName 'System.Web'

    # But in fact, you don't need that assembly at all, if you're running PowerShell 3.0 or later.
    # .NET Framework 4.0 added a similar class to the System.Net assembly, and you can use it
    # without loading any other types:
