PowerShell で Cognitive Services の呼び出し方

先日 Cogbot 勉強会に行った日に試したメモ
あとでもう少し真面目に書く

$EMOTION_API_KEY = '<Your API KEY>'
$URL = 'https://api.projectoxford.ai/emotion/v1.0/recognize'

$image = 'C:\Users\hoge\Desktop\1.jpg'

$result = Invoke-RestMethod `
    -Uri $URL `
    -Method Post `
    -ContentType 'application/octet-stream' `
    -Headers @{'Ocp-Apim-Subscription-Key' = $EMOTION_API_KEY } `
    -InFile $image 

$result | format-list *
