Elasticsearch java api以json为值更新api

Question

curl-xpost'localhost:9200/test/type1/1/_update'-d'{“script”：“ctx._source.name_of_new_field=\”value_of_new_field\“”}“

这是elasticsearch参考站点使用新字段更新现有文档的一个示例。https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html

我想用“新文件”更新现有文档，但用json作为“新字段的值”，而不是作为“新文件的值”的单个字符串。就像下面那样。

curl-xpost'localhost:9200/test/type1/1/_update'-d'{“script”：“ctx._source.test={\”newtest\“:\”hello\“}”}‘

它返回如下所示的错误。

{
  "error": {
    "root_cause": [
      {
        "type": "remote_transport_exception",
        "reason": "[Ravage 2099][127.0.0.1:9300][indices:data/write/update[s]]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "failed to execute script",
    "caused_by": {
      "type": "script_exception",
      "reason": "Failed to compile inline script [ctx._source.test2 = {\"test2\":\"hihi\"}] using lang [groovy]",
      "caused_by": {
        "type": "script_exception",
        "reason": "failed to compile groovy script",
        "caused_by": {
          "type": "multiple_compilation_errors_exception",
          "reason": "startup failed:\n4e487d5bc8afde27adf29b77e8427f5da1534843: 1: expecting '}', found ':' @ line 1, column 29.\n   ctx._source.test2 = {\"test2\":\"hihi\"}\n                               ^\n\n1 error\n"
        }
      }
    }
  },
  "status": 400
}

甚至可以用“JSON值”更新现有文档吗？还是每个更新请求都应该有单个字符串值？

您可以尝试对部分文档进行更新:https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#_updates_with_a_partial_document

比如：

curl -XPOST 'localhost:9200/test/type1/1/_update' -d '{
"doc" : {
    "test" : {
         "newTest" : "hello"
        }
    }
}'
