Besides the poplpular CI services Travis circleci there is AppVeyor which fills the Windows gap:
Continuous Delivery service for Windows
We cannot use Downloading AppVeyor build artifacts (PowerShell - basic example) due to the lack of PowerShell on our download server we "translated" the script to GNU Bash.
Declaring variables
PowerShell:
$apiUrl = 'https://ci.appveyor.com/api'
Bash:
API_URL="https://ci.appveyor.com/api"
GET a JSON file
PowerShell:
$project = Invoke-RestMethod -Method Get -Headers @{ "Content-Type" = "application/json" } -Uri "$uri"
Bash:
$PROJECT=$(curl -sS --header "Content-type: application/json" "$URI")
Parse JSON file
PowerShell (built-in):
$jobId = $project.build.jobs[0].jobId
Bash (with jq)
JOB_ID=$(echo $PROJECT | jq -r '.build.jobs[0].jobId')
Note: You can download jq (a lightweight and flexible command-line JSON processor) here
With httpbin you can easily experiment with this setup on your own:
$ curl -sS https://httpbin.org/get | jq -r '.url'
https://httpbin.org/get
For more detailed explanation in case you have more complex scenarios I highly recommend this post HTTP to HTTP with bash, curl and jq
Good luck with your migration!
