使用powershell使用ambari rest-api

Question

由于我们的监控是从Windows平台完成的，我们希望使用powershell从ambari-rest-api中检索信息。

在浏览器中可以探索api。首次登录，然后可以粘贴使用过的URL：https://someazurenode.westeurope.cloudapp.azure.com/ambari/api/v1/clusters它只是在浏览器中显示json响应。

卷曲：

curl --user myusr:mypwd --insecure -i -H 'X-Requested-By:ambari' -X GET https://someazurenode.westeurope.cloudapp.azure.com/ambari/api/v1/clusters

工作良好

在powershell中（在禁用ssl-verification **之后）：

$cred = New-Object System.Management.Automation.PSCredential ("myusr", (ConvertTo-SecureString "mypwd" -AsPlainText -Force))
Invoke-WebRequest -Method Get `
  -UseBasicParsing `
  -Uri "https://someazurenode.westeurope.cloudapp.azure.com/api/v1/clusters" -Headers @{"X-Requested-By"="Ambari"} `
  -Credential $cred

--> 404

这似乎是授权的东西，因此我尝试了下面的选项（**）：

Invoke-WebRequest -Method GET `
  -Uri "https://someazurenode.westeurope.cloudapp.azure.com/api/v1/clusters" `
  -Headers @{Authorization =[Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes('myusr:mypwd'))}

- > 404未找到

**无视ssl验证的灵感：Ignoring Self-Signed Certificates from Powershell Invoke-RestMethod doesn't work (it's changed again...)

**处理基本认证Use Invoke-WebRequest with a username and password for basic authentication on the GitHub API的灵感

Answer 1

找到问题，最后......在我们的案例中，我们需要通过3个步骤来修复连接：

1. 忽略证书错误（抱歉，我们还没有实现一个整洁的证书）
2. 使用基本身份验证而不是“普通”PowerShell凭据
3. 强制TLS版本。

从那里很容易检索信息。

function Disable-SslVerification
{
    if (-not ([System.Management.Automation.PSTypeName]"TrustEverything").Type)
    {
        Add-Type -TypeDefinition  @"
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;
public static class TrustEverything
{
    private static bool ValidationCallback(object sender, X509Certificate certificate, X509Chain chain,
        SslPolicyErrors sslPolicyErrors) { return true; }
    public static void SetCallback() { System.Net.ServicePointManager.ServerCertificateValidationCallback = ValidationCallback; }
    public static void UnsetCallback() { System.Net.ServicePointManager.ServerCertificateValidationCallback = null; }
}
"@
    }
    [TrustEverything]::SetCallback()
}
function Enable-SslVerification
{
    if (([System.Management.Automation.PSTypeName]"TrustEverything").Type)
    {
        [TrustEverything]::UnsetCallback()
    }
}

$domain = "my-cluster.westeurope.cloudapp.azure.com/ambari"
$usernm = "myusr"
$userpwd = "mypwd"

Disable-SslVerification
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$uri = "https://{0}/api/v1/clusters" -f $domain
Write-Output $uri

$credstring = "{0}:{1}" -f $usernm, $userpwd
$credbytes = [System.Text.Encoding]::ASCII.GetBytes($credstring)
$credbase64 = [System.Convert]::ToBase64String($credbytes)
$credAuthValue = "Basic {0}" -f $credbase64
$headers = @{ Authorization = $credAuthValue}

$result = "-"
$result = Invoke-RestMethod -Method Get -UseBasicParsing -Uri $uri -Headers $headers
$result
