创建针对多列表元素负载的GET操作RESTCONF URI

Let's break down how to build the correct RESTCONF URI to target a specific list element in your nested structure. RESTCONF uses a hierarchical path based on your data model, with special syntax to target individual list items using their key fields.

Step-by-Step Breakdown #

1. Start with the standard RESTCONF data root:
   All data retrieval URIs begin with /restconf/data — this is the base path for accessing configuration or state data via RESTCONF.

2. Traverse the container hierarchy:
   Follow the structure of your payload from top to bottom:

   • System (top-level container)
   • tm-items (child container)
   • sensor-items (child container)

3. Target the specific top-level list element:
   Lists in RESTCONF require you to specify their key field to select an individual item. For your SensorGroup-list, the key is id. Use the syntax list-name=key=value to pin down the exact element:

   • To get the SensorGroup-list item with id="10", append SensorGroup-list=id=10 to the path.

4. Drill into nested sub-lists (if needed):
   If you want to target a specific SensorPath-list item inside that group, repeat the list targeting syntax. Assuming depth is the key field for SensorPath-list, append /path-items/SensorPath-list=depth=1 to reach the item with depth="1".

Example URIs #

• Get the entire SensorGroup-list item with id=10:

  /restconf/data/System/tm-items/sensor-items/SensorGroup-list=id=10
  

• Get the specific SensorPath-list item (depth=1) inside the id=10 SensorGroup:

  /restconf/data/System/tm-items/sensor-items/SensorGroup-list=id=10/path-items/SensorPath-list=depth=1
  

• Get the id=20 SensorGroup's SensorPath item with depth=5:

  /restconf/data/System/tm-items/sensor-items/SensorGroup-list=id=20/path-items/SensorPath-list=depth=5
  

Key Notes #

• Always use the defined key field of the list to target individual items — this is the most efficient and standard approach in RESTCONF (reserve query param filtering for cases where you need to match non-key fields).
• Container names are used as-is in the path; only lists require the list-name=key=value syntax to select a specific entry.
