Issues connecting to the camera

[Akita54]

Hi, I’m trying to make a basic connection to my camera with the below commands. Once it gets to Invoke WebRequest, it errors. Any ideas why?

PS C: $Username = "xxxxxxxxx"
$Password = "yyyyyyyyyyy"

$AuthInfo = [Convert]::ToBase64String(
[Text.Encoding]::ASCII.GetBytes("${Username}:${Password}")
)

$Headers = @{
Authorization = "Basic $AuthInfo"
}
Invoke-WebRequest -Uri "http://192.168.0.90/config/rest/basic-device-info/v2beta"
-Method POST `
-Headers $Headers

Error
Invoke-WebRequest : Unable to connect to the remote server

@Akita54
The error shows: Unable to connect to the remote server.
This is just like a normal error when you can connect over network to your device.
Looks for me either your camera ip is wrong. Or may your device is HTTPS only.

[Akita54]

The IP is correct, I can HTTP the camera address and sign in manually via a browser. When I use HTTPS in the Invoke-WebRequest, I get this error: Invoke-WebRequest : The underlying connection was closed: Could not establish trust relationship for the SSL/TLS
secure channel.

@Akita54 yes because its an self signed.
i dont now why you use this api, but its "GET"

and your first post shows that you use "POST"

Hi @Akita54 ,

Powershell script (I used the ChatGPT 😉 ). Works with CMD only.

# Trust all SSL certificates (PowerShell 5.1)
Add-Type @"
using System.Net;
using System.Security.Cryptography.X509Certificates;

public class TrustAllCertsPolicy : ICertificatePolicy {
    public bool CheckValidationResult(
        ServicePoint srvPoint,
        X509Certificate certificate,
        WebRequest request,
        int certificateProblem) {
        return true;
    }
}
"@

[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

# Read credentials
$username = Read-Host "Username"
$password = Read-Host "Password" -AsSecureString

$plainPassword = [Runtime.InteropServices.Marshal]::PtrToStringAuto(
    [Runtime.InteropServices.Marshal]::SecureStringToBSTR($password)
)

# Build Basic Auth header
$authBytes  = [Text.Encoding]::ASCII.GetBytes("$($username):$($plainPassword)")
$authHeader = [Convert]::ToBase64String($authBytes)

# Invoke request
Invoke-WebRequest `
    -Uri "https://10.176.12.35/config/rest/basic-device-info/v2beta" `
    -Method GET `
    -Headers @{
        "Accept"        = "application/json"
        "Authorization" = "Basic $authHeader"
    }

Output

For HTTP

For HTTP, you need to use the Digest Auth

Powershell script (I used the ChatGPT 😉 )

$username = Read-Host "Username"
$password = Read-Host "Password" -AsSecureString

$cred = New-Object System.Net.NetworkCredential($username, $password)

$request = [System.Net.HttpWebRequest]::Create(
    "http://10.176.12.35/config/rest/basic-device-info/v2beta"
)
$request.Method = "GET"
$request.Accept = "application/json"
$request.Credentials = $cred
$request.PreAuthenticate = $true

$response = $request.GetResponse()
$reader   = New-Object System.IO.StreamReader($response.GetResponseStream())
$reader.ReadToEnd()

Output:

PS E:\Vivek\Discussions\1210> pwsh -ExecutionPolicy Bypass -File .\Sample2.ps1

  "data": {
    "allowAnonymous": true
  }
}

Note: If you face the following error using PS. Then check 1209
