function Invoke-ImageClassification {
param(
[string]$ImagePath,
[string]$ApiKey,
[ValidateRange(1,100)]
[int]$MaxResults = 5
)

try {
$base64Image = [Convert]::ToBase64String((Get-Content $ImagePath -Encoding Byte))
$headers = @{ "Ocp-Apim-Subscription-Key" = $ApiKey }
$body = @{ url = "data:image/jpeg;base64,$base64Image" } | ConvertTo-Json

$response = Invoke-RestMethod -Uri "https://eastus.api.cognitive.microsoft.com/vision/v3.1/analyze?visualFeatures=Categories"
-Method Post
-Headers $headers
-Body $body

$results = $response.categories | Select-Object name, score -First $MaxResults
return $results | Format-Table -AutoSize
}
catch {
Write-Error "分类失败:$($_.Exception.Message)"
}
}

实现原理分析:

  1. 将本地图像转换为Base64编码格式进行传输
  2. 通过Microsoft Cognitive Services视觉API实现智能分类
  3. 参数验证机制确保返回结果数量在合理范围
  4. 结构化返回结果便于后续处理分析
  5. 异常处理机制捕获网络请求和API调用错误

该脚本将传统图像管理升级为智能分类系统,特别适合需要处理大量用户生成内容的内容管理平台。
