the request carries entity id, and the entity in the request is not limited to entities such as personnel, cases and the like; the request is for obtaining a list of images from the entity id.
Step 2, traversing all adapters by the unified framework;
traversing all adapters in the step refers to sending a query request to each adapter;
step 3, the adapter sends a query request to the unified storage;
in this step, the query request is used to query the corresponding image according to the entity id.
Step 4, the adapter acquires a response returned by unified storage;
in the step, the response carries the queried image list result; and directly jumping to the step 7 when the returned image list result is not null, and executing the step 5 if the returned image list result is null:
