  11.     },
  12.     "task_id": 2
  13. }

1.4.2 获取所有的IndexLabel

Method & Url
  1. GET http://localhost:8080/graphs/hugegraph/schema/indexlabels
Response Status
  1. 200
Response Body
  1. {
  2.     "indexlabels": [
  3.         {
  4.             "id": 3,
  5.             "base_type": "VERTEX_LABEL",
  6.             "base_value": "software",
  7.             "name": "softwareByPrice",
  8.             "fields": [
  9.                 "price"
  10.             ],
  11.             "index_type": "RANGE"
  12.         },
  13.         {
  14.             "id": 4,
  15.             "base_type": "EDGE_LABEL",
  16.             "base_value": "created",
  17.             "name": "createdByDate",
  18.             "fields": [
  19.                 "date"
  20.             ],
  21.             "index_type": "SECONDARY"
  22.         },
  23.         {
  24.             "id": 1,
  25.             "base_type": "VERTEX_LABEL",
  26.             "base_value": "person",
  27.             "name": "personByCity",
  28.             "fields": [
  29.                 "city"
  30.             ],
  31.             "index_type": "SECONDARY"
  32.         },
  33.         {
  34.             "id": 3,
  35.             "base_type": "VERTEX_LABEL",
  36.             "base_value": "person",
  37.             "name": "personByAgeAndCity",
  38.             "fields": [
  39.                 "age",
  40.                 "city"
  41.             ],
  42.             "index_type": "SECONDARY"
  43.         }
  44.     ]
  45. }

1.4.3 根据name获取IndexLabel

Method & Url
  1. GET http://localhost:8080/graphs/hugegraph/schema/indexlabels/personByCity
Response Status
  1. 200
Response Body
  1. {
  2.     "id": 1,
  3.     "base_type": "VERTEX_LABEL",
  4.     "base_value": "person",
  5.     "name": "personByCity",
  6.     "fields": [
  7.         "city"
  8.     ],
  9.     "index_type": "SECONDARY"
  10. }

1.4.4 根据name删除IndexLabel

删除 IndexLabel 会导致删除相关的索引数据，会产生一个异步任务

Method & Url
  1. DELETE http://localhost:8080/graphs/hugegraph/schema/indexlabels/personByCity
Response Status
  1. 202
Response Body
  1. {
  2.     "task_id": 1
  3. }

注：

可以通过GET http://localhost:8080/graphs/hugegraph/tasks/1（其中”1”是task_id）来查询异步任务的执行状态，更多异步任务RESTful API
