[英]Elasticsearch java api update API with json as value
curl -XPOST'localhost:9200 / test / type1 / 1 / _update'-d'{“ script”:“ ctx._source.name_of_new_field = \\” value_of_new_field \\“”}'
这是来自Elasticsearch参考站点的一个示例,用于使用新字段更新现有文档。 https://www.elastic.co/guide/zh-CN/elasticsearch/reference/current/docs-update.html
我想用“新文件”来更新现有文档,但用json作为“新字段的值”而不是单个字符串作为“新文件的值”。 就像下面一样。
curl -XPOST'localhost:9200 / test / type1 / 1 / _update'-d'{“ script”:“ ctx._source.test = {\\” newTest \\“:\\” hello \\“}”}'
返回如下错误。
{
"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
}
甚至可以使用“ json值”更新现有文档吗? 还是每个更新请求都应具有单个字符串值?
您可以尝试Updates with a partial document
: https : //www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#_updates_with_a_partial_document
喜欢:
curl -XPOST 'localhost:9200/test/type1/1/_update' -d '{
"doc" : {
"test" : {
"newTest" : "hello"
}
}
}'
如果要添加JSON对象,只需使用常规的哈希,就像这样
curl -XPOST 'localhost:9200/test/type1/1/_update' -d '{
"script" : "ctx._source.test = ['newTest':'hello']"
}'
之后您的对象将如下所示
{
"test": {
"newTest": "hello"
}
}
