Powershell Neo4j connectivity Invoke-RestMethod

Question

I am trying to connect to a Neo4j via Invoke-RestMethod (PowerShell versions 3,4,5).

Based on web recommendations, I am setting URI: $Uri = "http://localhost:7474/db/data/cypher"

... followed by a call to invoke rest method (POST or GET, does not matter)

Invoke-RestMethod -Uri $Uri -Method Post -Body $Body -ContentType 'application/json'

Message I get is:

System.Net.WebException: The remote server returned an error: (401) Unauthorized.
   at Microsoft.PowerShell.Commands.WebRequestPSCmdlet.GetResponse(WebRequest request)
   at Microsoft.PowerShell.Commands.WebRequestPSCmdlet.ProcessRecord()

I tried putting in http://userId/pwd@localhost:7474.... but the error is the same.

Is there another way to pass authentication information to Neo4j?

Disabling security is not an option.

Thank you!

The authetication havs to bee the http standard authentication. You can do this in powershell for example with the following code.

    $user = 'user'
$pass = 'pass'

$pair = "$($user):$($pass)"

$encodedCreds = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($pair))

$basicAuthValue = "Basic $encodedCreds"

$Headers = @{
    Authorization = $basicAuthValue
}

Invoke-RestMethod -Uri $Uri -Method Post -Body $Body -ContentType 'application/json' -Headers $Headers

Background The error code 401 says that the authentication is not correct on the server.

I found this information in the documentation. https://neo4j.com/docs/developer-manual/3.4/http-api/authentication/
