What is the best way to stop triggered web jobs

Question

I got requirement from team like ,currently they are running the triggered jobs at particular intervals by setting up the schedule.They have setup schedule ,so as per the scheduled time those triggered jobs will run but at the time of deploy we must make sure the triggered jobs shouldn't run as it will not accept the deploy jar's into azure.So I want to run webjobs continuous jobs stop and as well as triggered jobs shouldn't run.It should check the triggered job running at the time of deploy if its running we can't deploy jar's even though if u stop continuous jobs.Please help me.How to accomplish the above task? whether we need to add any script to check triggered jobs running or not if it runs how to deploy jar's.

And other requirement is like,currently we are passing the parameters like

-webjobs @(@{"name"="abc";"typeName"='continuous'},@{"name"="def";"ty‌​peName"='continuous'‌​}) -website kgh -rg ghi....

But team want these parameters will be passed in a separate file.So that when they add new web job they can add in a file itself.how can I call if I put the parameter script in a separate file and pass to the webjobs script.

Any post deploy of webjobs I should validate whether the webjobs are started properly or not.So these 3 requirements I need to implement in the script.Kindly share me the script full filling the above requirement.

You can get the processes of current web app through Process kudu API, then check whether there is the process related to the WebJob (process name), if so, kill that process.

For example:

param(
[string]$webJobName,
[string]$userName,
[string]$password,
[string]$webAppName
)
$kuduApiAuthorisationToken="Basic {0}" -f [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $userName, $password)))
$kuduApiUrl="https://$webAppName.scm.azurewebsites.net/api/processes/"
$processes=Invoke-RestMethod -Uri $kuduApiUrl -Headers @{"Authorization"=$kuduApiAuthorisationToken;"If-Match"="*"} -Method GET
foreach($p in $processes){
    if($p.name -eq $webJobName){
    $killAPI="https://$webAppName.scm.azurewebsites.net/api/processes/$($p.id)"
    Invoke-RestMethod -Uri $killAPI -Headers @{"Authorization"=$kuduApiAuthorisationToken;"If-Match"="*"} -Method DELETE
    }
}

Parameter: -webJobName "XX" -userName "XX" -password "XX" -webAppName "XX"

Note: If there is $ in the username, such as $test, you can specify the username like -userName "`$test"

You can get the username and password from publish profile manually or programmatically: (Answered in your thread: Could any one help me how to stop and start azure webjobs through vsts)

Regarding put the parameter in a file:

parameter.json

[
  {
    "filepath": "data.csv",
    "Cols": "Col1,Col2,Col3"
  },
  {
    "filepath": "data2.csv",
    "Cols": "Col1,Col6,Col7,Col8"
  }
]

Code:

[object[]]$fileObj=Get-Content "parameter.json"|ConvertFrom-Json
foreach($fo in $fileObj){

}

Update:

Parameter.json:

{
    "userName": "user1",
    "password": "password1",
    "webAppName": "webapp1",
    "resourceGroup": "resourceGroup1",
    "webJobs": [   
      {
        "name": "abc",
        "typeName": "continuous"
      },
      {
        "name": "def",
        "typeName": "continuou‌"
      }
    ]
  }

Script:

 [object]$paramObj=Get-Content "PowerShellModuleProject1\parameter2.json"|ConvertFrom-Json 
    $userName =$paramObj.userName
    $password =$paramObj.password
    $webAppName =$paramObj.webAppName
    $resourceGroup=$paramObj.resourceGroup
    [object[]]$webJobs=$paramObj.webJobs
    foreach($wj in $webjobs){
     if($wj.typeName -eq "continuous")
     {
Invoke-AzureRmResourceAction -ResourceGroupName $resourceGroup -ResourceType Microsoft.Web/sites/ContinuousWebJobs -ResourceName "$webAppName/$($wj.name)" -Action start -ApiVersion 2015-08-01 -Force
      Write-Host "continuous"
     Write-Host $wj.name
     }
     else{
     Invoke-AzureRmResourceAction -ResourceGroupName $resourceGroup -ResourceType Microsoft.Web/sites/TriggeredWebJobs -ResourceName "$webAppName/$($wj.name)" -Action run -ApiVersion 2015-08-01 -force
     Write-Host "triggered"
     Write-Host $wj.name
     }
     }
