如何通过HTTP API更新Collection中已存在的Doc - 向量检索服务

本文介绍如何通过HTTP API更新Collection中已存在的Doc。

说明

若更新Doc时指定id不存在，则本次更新Doc操作无效
如只更新部分属性fields，其他未更新属性fields默认被置为null

前提条件

已创建Cluster：创建Cluster。
已获得API-KEY：API-KEY管理。

Method与URL

HTTP

PUT https://{Endpoint}/v1/collections/{CollectionName}/docs

使用示例

说明

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。
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Doc

Shell

curl -XPUT \
  -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

# example output:
# {"request_id":"b1ce1b30-14a2-4e38-9931-f0b832660da9","code":0,"message":"Success","output":[{"doc_op":"update","id":"1","code":0,"message":""}]}

插入带有Fields的Doc

Shell

curl -XPUT \
  -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

# example output:
# {"request_id":"0d22a37f-e906-4121-8408-7f1b685bb211","code":0,"message":"Success","output":[{"doc_op":"update","id":"2","code":0,"message":""}]}

批量插入Doc

Shell

curl -XPUT \
  -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

# example output:
# {"request_id":"d9a81bbc-7010-4902-a91c-7402e13143fa","code":0,"message":"Success","output":[{"doc_op":"update","id":"3","code":0,"message":""},{"doc_op":"update","id":"4","code":0,"message":""},{"doc_op":"update","id":"5","code":0,"message":""}]}

插入带有Sparse Vector的Doc

Shell

curl -XPUT \
  -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

# example output:
# {"request_id":"bb28479a-1a54-4d0b-a083-6399ac7bceeb","code":0,"message":"Success","output":[{"doc_op":"update","id":"6","code":0,"message":""}]}
