    • Use policy action scripts to get, update, or set values in cloud requests.

    Avant de commencer

    Role required: sn_cmp.cloud_governor or admin.

    Pourquoi et quand exécuter cette tâche

    For more information on using scripts, see Cloud scripts and cloud script templates.

    Procédure

    1. On the Cloud Admin Portal, navigate to Govern > Policies.
    2. On the Policy Action Scripts tab, click New, enter a unique and descriptive Name and Description, fill in the form, and then click Submit.
      After you enter a name, a script appears with a variable that uses the name that you entered.
      Field Description
      Action Script Category Choose another category or keep the one you created in an earlier step.
      Script Modify the customScripts function in the script. This is the only part of the script that you need to modify.

    Exemple

    The following example script determines whether the user belongs to a user group and then overrides the user-specified application server node name value with the value MyNodeName.
    
customScript : function(formData){
  var groups = this.parameters.userData.groups; 
    if( groups.length > 0){ 
      formData.App_Server_NodeName = "MyNodeName"; 
    }
  return formData;
},

    This example returns a random number:

    
customScript : function(formData){
  var min = 10000;
  var max = 99999;
  var num = Math.floor(Math.random() * (max - min + 1)) + min;
  formData.randomNumber = num + "";  
  return formData;
},

    This example script adds three hours to the lease date using the base-system GlideDateTime class.

    
var SetLeaseShort = Class.create();
SetLeaseShort.prototype = Object.extendsObject(sn_cmp.PolicyExecutionBase, {
	customScript : function(formData){
		// Manipulation of form parameters are supported. Changes in any other attributes
              // will be ignored.
		// The data available for manipulation is as follows:
		// Form Data -  for example: StackName can be accessed through formData.StackName
		// formData.StackName = "MyStack";
		// User Data  - for example: User Id can be accessed through this.parameters.userData
		// if(this.parameter.userData.userId == 'servicenowuserId')
		// this.info("id = " + formData.StackName);
		
		// var leaseValue = now();
		// leaseValue = leaseValue.setHours(leaseValue.getHours()+4);
		// formData.LeaseEndDate = leaseValue;
		
		if (formData.hasOwnProperty("LeaseEndDate")) {
			gdt = new GlideDateTime();
			// 10800 = 3 hours
			gdt.addSeconds(10800);
			formData.LeaseEndDate = gdt.getDisplayValue();
		}	
		return formData;
	},
	execute: function() {
		if(this.parameters !=  null && this.parameters.formData != null){
        	var inputData = JSON.parse(JSON.stringify(this.parameters.formData));
		    var outputFormData = this.customScript(inputData);
            if( outputFormData != null){
                this.parameters.formData = outputFormData;
            }
       	}
		var output = {};
		output.answer = this.parameters;
		return JSON.stringify(output);
	},
	type : 'SetLeaseShort'
});	

var SetLeaseShortObj = new SetLeaseShort(inputAttributes);
var outputParams = SetLeaseShortObj.execute();
gs.info( "Output of script is = " + outputParams);

    This example script sets the user-specified Azure Wordpress DNS name field from the form to the same name as the stack name:

    var WordpressFill = Class.create();
WordpressFill.prototype = Object.extendsObject(sn_cmp.PolicyExecutionBase, {
	customScript : function(formData){
		// Manipulation of form parameters are supported. Changes in any other attributes
        // will be ignored.
		// The data available for manipulation is as follows:
		// Form Data -  for example: StackName can be accessed through formData.StackName
		// formData.StackName = "MyStack";
		// User Data  - for example: User Id can be accessed through this.parameters.userData
		// if(this.parameter.userData.userId == 'servicenowuserId')
		//this.info("id = " + formData.StackName);
		
		formData.Azure_Wordpress_v6_vmDnsName = formData.StackName;
		
		return formData;
	},
	execute: function() {
		if(this.parameters !=  null && this.parameters.formData != null){
        	var inputData = JSON.parse(JSON.stringify(this.parameters.formData));
		    var outputFormData = this.customScript(inputData);
            if( outputFormData != null){
                this.parameters.formData = outputFormData;
            }
       	}
		var output = {};
		output.answer = this.parameters;
		return JSON.stringify(output);
	},
	type : 'WordpressFill'
});	

var WordpressFillObj = new WordpressFill(inputAttributes);
var outputParams = WordpressFillObj.execute();
gs.info( "Output of script is = " + outputParams);
