How to use LSE File Proxy and prepare tasks

1. You run simple http server with basic auth on the machine where your local storage is.

pip install sauth  # sauth - simple http file server with auth
sauth admin 12345 -d /path/to/storage

2. Now you can have access to images from your storage this way:

<http://localhost:8333/image.jpg>  # image is stored as /path/to/storage/image.jpg

3. Let’s assume your storage server has an IP address 192.168.1.42, so the file name will be

<http://192.168.1.42/image.jpg>

4. LSE server has API in the same network, let it be 192.168.1.77. So, files from storage 192.168.77.42 will be accessible from LSE 192.168.1.77.

5. Let’s expose your storage files to annotators by enabling the basic auth proxy on LSE side:

6. Now we can prepare LS tasks for import:

 {
  "image":"<http://192.168.1.42/image.jpg>",
  "meta": {
    "info": "test_image"
    "text": "some text"
  }          
}

8. LSE will download this image and return to annotators it using its own proxy by this url:
