A Basic Powershell Webserver

Powershell_HTTP_Server.MD

This is a super simple Exmple of how to create a very basic powershell webserver

# Http Server
$http = [System.Net.HttpListener]::new() 

# Hostname and port to listen on
$http.Prefixes.Add("http://localhost:8080/")

# Start the Http Server 
$http.Start()

# Log to terminal 
if($http.IsListening){write-host "Ready! $($http.Prefixes)" -f 'green'}





# INFINTE LOOP
# Used to listen for requests
while ($http.IsListening) {
    
    

    # Get Request Url
    # When a request is made in a web browser the GetContext() method will retuen the request url
    # Our ROUTE EXAMPLE's will use this to decide how to respond
    $context = $http.GetContext()



    # ROUTE EXAMPLE 1
    if ($context.Request.RawUrl -eq '/') {

        # We can log the request to the terminal
        write-host "A request has been made from $($context.Request.UserHostAddress) for $($context.Request.Url)" -f Magenta

        # the html/data you want to send to the browser
        # you could replace this with ( Get-Content "C:\some\path\index.html" | Out-String )
        [string]$html = "<h1>A Powershell Webserver</h1><p>Root Route</p>" 
        
        #resposed to the request
        $buffer = [System.Text.Encoding]::UTF8.GetBytes($html) # convert htmtl to bytes
        $context.Response.ContentLength64 = $buffer.Length
        $context.Response.OutputStream.Write($buffer, 0, $buffer.Length) #stream to broswer
        $context.Response.OutputStream.Close() # close the respose
    
    }



    # ROUTE EXAMPLE 2
    if ($context.Request.RawUrl -eq '/some/path') {

        # We can log the request to the terminal
        write-host "A request has been made from $($context.Request.UserHostAddress) for $($context.Request.Url)" -f Magenta

        # the html/data you want to send to the browser
        # you could replace this with ( Get-Content "C:\some\path\index.html" | Out-String )
        [string]$html = "<h1>A Powershell Webserver</h1><p>Some Other Route</p>" 

        #resposed to the request
        $buffer = [System.Text.Encoding]::UTF8.GetBytes($html) # convert htmtl to bytes
        $context.Response.ContentLength64 = $buffer.Length
        $context.Response.OutputStream.Write($buffer, 0, $buffer.Length) #stream to broswer
        $context.Response.OutputStream.Close() # close the respose
    
    }


    # powershell will continue looping and listen for new requests...
    

} 

# Note:
# To end the loop you have to kill the powershell terminal. ctrl-c wont work :/
