A couple of weeks ago I\u2019ve been working with a customer in this use case and I think is very useful to share with you<\/p>\n\n\n\n

Basically, the idea is to upload a file in a Catalog Item Request and then, process it in vRO.<\/p>\n\n\n\n

So, let\u2019s start working!!<\/p>\n\n\n\n

Service design<\/h1>\n\n\n\n

The idea for this simple service is to upload a file in Service Broker Catalog so the information in the file can be processed in a vRO workflow. For this example, the workflow itself doesn\u2019t have any input parameters. The \u201cfile Upload\u201d parameter is added in Form Designer and retrieved the value from workflow during execution.<\/p>\n\n\n\n

vRA Catalog Item Form<\/h1>\n\n\n\n

From a Catalog perspective the Blueprint, for this example, is a simple XaaS workflow presented throught the Service Catalog.<\/p>\n\n\n\n

This workflow doesn\u2019t have any input parameters, all parameter are gathered via API calls in vRO workflow.<\/p>\n\n\n\n

I\u2019ve added, using the form designer, an input value of type \u201cFile Upload\u201d, as we can see in the screenshot.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Here we can see the input to be used is a \u201cFile Upload\u201d type, and no vRO input is associated with it.<\/p>\n\n\n\n

vRO Workflow<\/h1>\n\n\n\n

For this example, the Workflow we are using, is divided in two main parts<\/p>\n\n\n\n

\u00abGet Deployment Details\u00bb<\/strong><\/p>\n\n\n\n

  1. Get Token<\/li><\/ol>\n\n\n\n

    First step is to get the token so we can start executing rest calls to vRA.<\/p>\n\n\n\n

    The following example is a simple code to obtain a token based on user and password:<\/p>\n\n\n\n

    \n
    \n

    \/\/Get Token<\/code><\/p>

    var url = \"\/csp\/gateway\/am\/api\/login?access_token\";<\/code><\/p>

    var requestContent = '{ \"username\": \"' + username + '\", \"password\": \"' + password + '\"}';<\/code><\/p>

    var request = vRARestHost.createRequest(\"POST\", url, requestContent);<\/code><\/p>

    request.setHeader(\"Content-Type\", \"application\/json\");<\/code><\/p>

    request.setHeader(\"Cache-Control\", \"no-cache\");<\/code><\/p>

    var RestResponse = request.execute();<\/code><\/p>

    var token = JSON.parse(RestResponse.contentAsString).access_token;<\/code><\/p><\/blockquote>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

    1. Get Deployment based on deploymentId<\/em><\/li><\/ol>\n\n\n\n

      Using the token we\u2019ve obtained in the previous step, we will use vRA API to get the deployment details for the request.<\/p>\n\n\n\n

      The requisites to run this code are:<\/p>\n\n\n\n
