Curl 从php调用AWS Rekognition HTTP API的示例

我正在学习亚马逊Rekognition API。我想知道是否可以通过curl调用Amazon Rekognition API？

当然可以。下面是如何构造curl请求的示例

curl -X POST \
  https://rekognition.us-east-1.amazonaws.com \
  -H 'Authorization: AWS4-HMAC-SHA256 Credential=**accessKey**/20180930/us-east-1/rekognition/aws4_request, SignedHeaders=content-length;content-type;host;x-amz-date;x-amz-target, Signature=**signature**' \
  -H 'Content-Length: **body legnth**' \
  -H 'content-type: application/x-amz-json-1.1' \
  -H 'host: rekognition.us-east-1.amazonaws.com' \
  -H 'x-amz-date: 20180930T143928Z' \
  -H 'x-amz-target: RekognitionService.DetectLabels' \
  -d '{"Image":{"S3Object":{"Bucket":"**bucket name**", "Name":"**file name**"}}}'
