Requests to one of the proxy endpoints will be forwarded to the backend. When a successful result is returned from the backend, content is extracted from the body and sent to the client. The following proxy endpoints are available:
| /json | All metadata is extracted from the backend response using
exiftool -j -g -a -struct and returned to the client with
Content-Type header set to application/json. |
| /xmp | The xmp packet is extracted from the response and returned to the client
with Content-Type header set to application/rdf+xml. |
| /preview | The first preview image is extracted from the backend response and returned to the client as a JPEG image. |
- /pageimage/{N}
- The Nth page image is extracted from the backend response and returned to the
client as a JPEG image. Index starts from
0.
Run twist exifproxy --backend=https://raw.githubusercontent.com/exiftool/exiftool/master/t/images
Then use curl to access any of the exiftool example images through one of the proxy endpoints:
curl http://localhost/xmp/Photoshop.psd curl http://localhost/json/GIMP.xcf
