ทดสอบ OCR ของ Asure เป็น Rest api

      public void simplePost()

        {

            HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create("https://westcentralus.api.cognitive.microsoft.com/vision/v2.0/ocr?language=en&detectOrientation=true&textAngle=90");

            //       httpWebRequest.Headers.Add("Host","westcentralus.api.cognitive.microsoft.com");

           // getkey from microsoft

ทดลอง ล่าสุด ไม่ได้ ยังไม่รู้สาเหตุ


Code ของ Curl

curl -i -d "{\"url\": \"http://abc.com/x.jpg\"}" -H "Content-Type: application/json" -H "Prediction-Key: 1212324234123412341234" -X POST https://southcentralus.api.cognitive.microsoft.com/customvision/v3.0/Prediction/xxxx-aaaa-bbb-ccc/classify/iterations/Iteration3/url?application=CHK_ABC


Code ของ Python 3.8 ต้องลง rest ก่อน python -m pip install rest



import requests

headers = {
    'Content-Type': 'application/json',
    'Prediction-Key': 'key',
}

params = (
    ('application', 'CHK_ABC'),
)

data = '{"url": "http://abc.com/x.jpg"}'

response = requests.post('https://southcentralus.api.cognitive.microsoft.com/customvision/v3.0/Prediction/prjectid-xxxx/classify/iterations/Iteration3/url', headers=headers, params=params, data=data)

print(response.text)
