如何通过HTTP API插入或更新Doc

本文介绍如何通过HTTP API向Collection中插入或更新Doc。

---

说明

1. 若调用本接口时Doc Id已存在，则等同于更新Doc；Doc Id不存在，则等同于插入Doc。

2. 若调用本接口时不指定Doc Id，则等同于插入Doc，DashVector会自动生成Doc Id，并在返回结果中携带id信息。

前提条件

• 已创建Cluster：创建Cluster。

• 已获得API-KEY：API-KEY管理。

Method与URL

HTTP

POST https://{Endpoint}/v1/collections/{CollectionName}/docs/upsert

使用示例

说明

1. 需要使用您的api-key替换示例中的YOUR_API_KEY、您的Cluster Endpoint替换示例中的YOUR_CLUSTER_ENDPOINT，代码才能正常运行。

2. 本示例需要参考新建Collection-使用示例提前创建好名称为quickstart的Collection

插入或更新Doc

Shell

curl -XPOST \
  -H 'dashvector-auth-token: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
  "docs": [{"id": "1", "vector": [0.1, 0.2, 0.3, 0.4]}]
  }' https://YOUR_CLUSTER_ENDPOINT/v1/collections/quickstart/docs/upsert

# example output:
# {"request_id":"1b8b4ada-1148-49ce-82e3-f7f521bb6f3b","code":0,"message":"Success","output":[{"doc_op":"insert","id":"1","code":0,"message":""}]}

插入或更新不带有Id的Doc

Shell

curl -XPOST \
  -H 'dashvector-auth-token: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
  "docs": [{"vector": [0.1, 0.2, 0.3, 0.4]}]
  }' https://YOUR_CLUSTER_ENDPOINT/v1/collections/quickstart/docs/upsert

# example output:
# {"request_id":"9c3f2441-c47b-43a0-bb84-127ff6a88711","code":0,"message":"Success","output":[{"doc_op":"insert","id":"6176745980928","code":0,"message":""}]}

插入或更新带有Fields的Doc

Shell

curl -XPOST \
  -H 'dashvector-auth-token: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "docs": [
      {
      	"id": "2", 
        "vector": [0.2, 0.3, 0.4, 0.5], 
        "fields": 
          {
            "age": 70, 
            "name": "zhangshan",
            "anykey1": "str-value",
            "anykey2": 1,
            "anykey3": true,
            "anykey4": 3.1415926
          }
      }
    ]
   }' https://YOUR_CLUSTER_ENDPOINT/v1/collections/quickstart/docs/upsert

# example output:
# {"request_id":"e1467d91-f4fd-4944-9ec0-1634de426db1","code":0,"message":"Success","output":[{"doc_op":"insert","id":"2","code":0,"message":""}]}

批量插入或更新Doc

Shell

curl -XPOST \
  -H 'dashvector-auth-token: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{ 
    "docs": [ 
      {"id": "3", "vector": [0.3, 0.4, 0.5, 0.6]},
      {"id": "4", "vector": [0.4, 0.5, 0.6, 0.7], "fields": {"age": 20, "name": "zhangsan"}},
      {"id": "5", "vector": [0.5, 0.6, 0.7, 0.8], "fields": {"anykey": "anyvalue"}}
    ]
   }' https://YOUR_CLUSTER_ENDPOINT/v1/collections/quickstart/docs/upsert

# example output:
# {"request_id":"113d221b-ec79-4fde-b546-58db5154e49d","code":0,"message":"Success","output":[{"doc_op":"insert","id":"3","code":0,"message":""},{"doc_op":"insert","id":"4","code":0,"message":""},{"doc_op":"insert","id":"5","code":0,"message":""}]}

插入或更新带有Sparse Vector的Doc

Shell

curl -XPOST \
  -H 'dashvector-auth-token: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "docs": [
      {"id": "6", "vector": [0.1, 0.2, 0.3, 0.4], "sparse_vector":{"1":0.4, "10000":0.6, "222222":0.8}}
    ]
   }' https://YOUR_CLUSTER_ENDPOINT/v1/collections/quickstart/docs/upsert

# example output:
# {"request_id":"c401e51d-430e-4c49-9d07-c944ec94de7b","code":0,"message":"Success","output":[{"doc_op":"insert","id":"6","code":0,"message":""}]}
