我尝试创建一个简单的模板，包括一些动态模板，但我似乎无法为文档编制索引。
我得到错误:
400 {"error":"MapperParsingException[mapping [_default_]]; nested: ClassCastException[java.util.LinkedHashMap cannot be cast to java.util.List]; ","status":400}
如果我删除 JSON 的 dynaic_templates 部分，它会正常工作。
我做错了什么？
以下是 python 代码的复制:
import requests
import json
template = {
"template": "some_index_*",
"settings": {
"index": {
"number_of_replicas": "0",
"number_of_shards": "8",
}
},
"mappings": {
"_default_": {
"_all": {
"enabled": False
},
"properties": {
"H1": {
"properties": {
"sub1": {
"doc_values": True,
"type": "boolean",
"index": "not_analyzed"
},
"sub2": {
"index": "no",
"type": "string"
},
}
}
},
"dynamic_templates": {
"text_indexed_template": {
"match_mapping_type": "string",
"mapping": {
"index": "not_analyzed",
"type": "string",
"doc_values": True
},
"match": "*_idx"
}
},
"_source": {
"compress": False
}
}
},
}
res = requests.put(
url="http://127.0.0.1:9200/" + "_template/my_template/",
data=json.dumps(template)
)
print res.status_code, res.content
new_doc = {
"H1": {
"sub1": True,
"sub2": "testing, testing"
}
}
res = requests.post(
url="http://127.0.0.1:9200/" + 'some_index_tryme/record/',
data=json.dumps(new_doc)
)
print res.status_code, res.content
最佳答案
dynamic_templates 应该是一个元素数组，意味着被 [ ] 包围。所以，你的应该是这样的:
"dynamic_templates": [
{
"text_indexed_template": {
"match_mapping_type": "string",
"mapping": {
"index": "not_analyzed",
"type": "string",
"doc_values": true
},
"match": "*_idx"
}
}
]
