This post is part of the series on PowerShell Snippets.

In the previous post, I showed how a single element could be retrieved from a GitHub release by executing curl and selecting the required element.

I quickly discovered that the element retrieved in this was contained some additional characters and I needed only the numeric ones. The PowerShell below will extract the numeric elements of the $id variable and return them in the $releaseID variable:

$releaseID = $id -replace "[^0-9]" , ''

While looking into uploading a release asset to a GitHub release, I discovered that to do this I needed the internal numeric id for a release and not just the id I’d given it. The element I needed from the GitHub json was id which can be retrieved using the below PowerShell which executes curl and then selects a single element:

$ghAuthorizationToken = "ghp_authorizationtoken"

$ghUser="username"
$ghRepo="repositoryname"
$ghTag="v1.4.2"

$URL= "https://api.github.com/repos/$ghUser/$ghRepo/releases/tags/$ghTag"

$Json=(curl.exe $URL)|ConvertFrom-json

$id=$Json| Select id

The following PowerShell command will execute curl passing in the authorization token and json parameters defined above the curl statement.

The main difference between this and curl on a normal command line is that you need to do curl.exe which is a built in alias for the Invoke-WebRequest cmdlet:

$ghAuthorizationToken = "ghp_authorizationtoken"
$ghUser = "username"
$ghRepo = "repository name"

$json = "
    { \`"tag_name\`": \`"$ghTag\`", \`"target_commitish\`": \`"main\`", \`"name\`": \`"$ghTag\`", \`"body\`": \`"$ghTag release\`", \`"draft\`" :false, \`"prerelease\`": false, \`"generate_release_notes\`": false }
"

curl.exe -X POST -H "Accept: application/vnd.github+json" -H "Authorization: token $ghAuthorizationToken" https://api.github.com/repos/$ghUser/$ghRepo/releases -d "$json"

The variables at the top need to be changed to those for your GitHub account and repository.

The following PowerShell shows the format required for use in Curl (which I will cover in the next post of this series). It took me a number of attempts to get the format correct; the backticks (`) are needed to escape the double quotes (") for PowerShell and the backslashes (\) to escape them for the curl command:

$json = "
    { \`"tag_name\`": \`"$ghTag\`", \`"target_commitish\`": \`"main\`", \`"name\`": \`"$ghTag\`", \`"body\`": \`"$ghTag release\`", \`"draft\`" :false, \`"prerelease\`": false, \`"generate_release_notes\`": false }
